| abstract = {Steady states of driven lattice gases with open boundaries are investigated. Particles are fed into the system at one edge, travel under the action of an external field, and leave the system at the opposite edge. Two types of phase transitions involving nonanalytic changes in the density profiles and the particle number fluctuation spectra are encountered upon varying the feeding rate and the particle interactions, and associated diverging length scales are identified. The principle governing the transitions is the tendency of the system to maximize the transported current.}, | |

| abstract = {A theoretical analysis of charged adsorbates on a metal surface reveals a pronounced polarity asymmetry between electropositive and electronegative species, thus reproducing a well known but so far not properly understood experimental fact. For ionic adsorbates on metal surfaces, we analyze the several, often canceling, terms that contribute to the change of the interface dipole and, hence, to work-function changes, Δϕ. We demonstrate that for the prototypic case of I on Cu(111) the magnitudes and the signs of these terms can be understood on the basis of their physical and chemical origins. An important consequence of their cancellation is that negatively charged adsorbates can lead to a paradoxical Δϕ{\textless}0 rather than the expected Δϕ{\textgreater}0.}, | |

| abstract = {The CO oxidation reaction on Pt-group metals (Pt, Rh, and Pd) has been investigated at low ([less-than-or-equals, slant]10-3 Torr) and near atmospheric (1-102 Torr) pressures in a batch reactor under steady-state conditions and at various gaseous reactant compositions using PM-IRAS and kinetic measurements. The results indicate that Langmuir-Hinshelwood kinetics adequately provides a general description of the kinetic trends over a wide range of pressures provided that mass transfer effects are considered. At high pressures, the reaction kinetics fall into three regimes: a CO-inhibited low temperature regime where the reaction rate is determined by CO desorption; a mass transfer limited regime at high temperatures; and a transient, high-rate regime which lies in between the other two regimes. The data show that the most reactive surface phase, at both low and high pressures, is a CO-uninhibited phase. This surface phase is not an oxide phase, but a surface phase that contains primarily chemisorbed atomic oxygen and a low coverage of CO.}, | |

The evolution of the microstructure, the average grain size, the variance of grain size and the distribution of grain-boundary mis-orientation of the deposit are also considered in simulations. The model has proven capable of capturing some key aspects of nucleation and growth mechanism including the nucleation type (e.g. homogeneous or heterogeneous), texture development, the growth of grains and higher energetic state of grain boundaries.

| abstract = {The coverage of surface adsorbates influences both the number and types of sites available for catalytic reactions at a heterogeneous surface, but accounting for adsorbate–adsorbate interactions and understanding their implications on observed rates remain challenges for simulation. Here, we demonstrate the use of a density functional theory (DFT)-parameterized cluster expansion (CE) to incorporate accurate adsorbate–adsorbate interactions into a surface kinetic model. The distributions of adsorbates and reaction sites at a metal surface as a function of reaction conditions are obtained through Grand Canonical Monte Carlo simulations on the CE Hamiltonian. Reaction rates at those sites are obtained from the CE through a DFT-parameterized Brønsted–Evans–Polyani (BEP) relationship. The approach provides ready access both to steady-state rates and rate derivatives and further provides insight into the microscopic factors that influence observed rate behavior. We demonstrate the approach for steady-state O2 dissociation at an O-covered Pt (1 1 1) surface—a model for catalytic NO oxidation at this surface—and recover apparent activation energies and rate orders consistent with experiment.}, | |

| abstract = {Surface science emerged in the 1960s with the development of reliable ultrahigh vacuum apparatus, providing exact structures of surfaces of metal single crystals, information about their compositions, and relationships between surface structure and composition and catalytic reaction rates. Catalysis, the acceleration of a chemical reaction by a catalyst (substance), provided much of the driving force for the early development of surface science.As surface science continues its rapid development, this book illustrates how it is still driven by the challenges of catalysis and how both theory and scanning tunneling microscopy have forcefully emerged as essential tools. It is also evident how surface science continues to serve as the foundation of catalytic science.This is a compendium written by leading surface scientists presenting an incisive assessment of up-to-date theoretical and experimental results constituting the foundation of fundamental understanding of surface catalysis.This paperback edition is adapted from the serial Advances in Catalysis, Volume 45, ISBN: 0-12-007845-7.COVERAGE INCLUDES: Dynamics of reactions at surfaces on time scales ranging from 10-13s to 103s Density functional theory of adsorption and surface chemical reactions Catalysts in action: atomic-resolution STM images elucidating elementary reactions on surfaces Adsorption energetics and bonding: femtomole calorimetry and first-principles theory Active sites on oxide catalysts: from single crystals to powders Model supported catalysts: metal particles on well-ordered oxide layers Vibrational spectra of reaction intermediates on catalyst surfaces by sum frequency generation}, | |

| abstract = {The optimization of ab initio molecular geometries is discussed. Based on comparisons of 30 minimizations and 15 saddle-point optimizations, the most efficient combination of coordinate system, approximate and exact Hessians, and step control is determined. Use of a proposed set of extra-redundant internal coordinates is shown to reduce the number of geometry steps significantly relative to the use of redundant coordinates. Various update schemes are tested for minimum and saddle-point optimizations, including combination formulas. The complete expressions for the first and second derivatives of the Wilson B matrix are presented, thereby avoiding the need to calculate this by finite-difference methods. The presented scheme appears to be the most efficient, robust and generally applicable scheme to date. © 2002 American Institute of Physics.}, | |

| abstract = {{\textless}p{\textgreater}{\textless}br/{\textgreater}Adsorbed oxygen at room temperatures exists on Pd(110) in two states, a surface state ([beta]2) and a more weakly bound state ([beta]1), previously designated as "subsurface" oxygen. The "subsurface" state was postulated as responsible for the oscillations in the kinetics of catalytic CO oxidation observed on this surface. However, previous studies have cast doubt on this explanation. We have investigated the interaction of oxygen on Pd(110) by temperature programmed desorption (TPD), ultraviolet photoemission spectroscopy (UPS) and x-ray photoelectron spectroscopy (XPS). The XPS combines conventional UHV with in-situ surface analysis in controlled atmospheres of up to 1 mbar. UPS work function measurements show a decrease with oxygen adsorption, coinciding with [beta]1 formation observed in TPD as reported previously. XPS measurements of the Pd 3d5/2 line show only oxyg induced surface core-level shifts (SCLS) for oxygen exposures as high as 22 800 L (po2 = 1.0 × 10-4 mbar and T = 400 K). surface-sensitive XPS measurements and TPD for higher oxygen exposures (po2 = 4.0 × 10-2 mbar for 20 min at T = 400 K) s oxide formation coinciding with a corresponding high increase in [beta]1 formation. These results for oxygen pressures and temperatures in the oscillation regime, suggest that the oscillatory behavior on this surface may be due to an oxidation and reduction mechanism.{\textless}/p{\textgreater}}, | |

| abstract = {The present status of development of the density-functional-based tight-binding (DFTB) method is reviewed. As a two-centre approach to density-functional theory (DFT), it combines computational efficiency with reliability and transferability. Utilizing a minimal-basis representation of Kohn-Sham eigenstates and a superposition of optimized neutral-atom potentials and related charge densities for constructing the effective many-atom potential, all integrals are calculated within DFT. Self-consistency is included at the level of Mulliken charges rather than by self-consistently iterating electronic spin densities and effective potentials. Excited-state properties are accessible within the linear response approach to time-dependent (TD) DFT. The coupling of electronic and ionic degrees of freedom further allows us to follow the non-adiabatic structure evolution via coupled electron-ion molecular dynamics in energetic particle collisions and in the presence of ultrashort intense laser pulses. We either briefly outline or give references describing examples of applications to ground-state and excited-state properties. Addressing the scaling problems in size and time generally and for biomolecular systems in particular, we describe the implementation of the parallel `divide-and-conquer' order-N method with DFTB and the coupling of the DFTB approach as a quantum method with molecular mechanics force fields.}, | |

| abstract = {We present a mathematical framework for constructing and analyzing parallel algorithms for lattice Kinetic Monte Carlo (KMC) simulations. The resulting algorithms have the capacity to simulate a wide range of spatio-temporal scales in spatially distributed, non-equilibrium physiochemical processes with complex chemistry and transport micro-mechanisms. The algorithms can be tailored to specific hierarchical parallel architectures such as multi-core processors or clusters of Graphical Processing Units (GPUs). The proposed parallel algorithms are controlled-error approximations of kinetic Monte Carlo algorithms, departing from the predominant paradigm of creating parallel KMC algorithms with exactly the same master equation as the serial one. Our methodology relies on a spatial decomposition of the Markov operator underlying the KMC algorithm into a hierarchy of operators corresponding to the processors' structure in the parallel architecture. Based on this operator decomposition, we formulate Fractional Step Approximation schemes by employing the Trotter Theorem and its random variants; these schemes, (a) determine the communication schedule\vphantom{\{}\} between processors, and (b) are run independently on each processor through a serial KMC simulation, called a kernel, on each fractional step time-window. Furthermore, the proposed mathematical framework allows us to rigorously justify the numerical and statistical consistency of the proposed algorithms, showing the convergence of our approximating schemes to the original serial KMC. The approach also provides a systematic evaluation of different processor communicating schedules.}, | |

| abstract = {Optical IR-visible sum-frequency generation (SFG) surface vibrational spectroscopy was applied for in situ detection of chemisorbed CO during heterogeneous CO oxidation on a polycrystalline platinum catalyst. The substrate temperature was between 300 and 700 K at a total pressure of 20 mbar. Experiments were carried out under laminar flow conditions in a well-defined stagnation point flow geometry to allow for a detailed comparison with numerical reactive flow simulations. These were carried out to investigate the interaction among surface heterogeneity, catalytic surface reactions and gas-phase processes, and their coupling by molecular transport. To reproduce the experimental results, the model for the Pt foil is based on two different adsorption sites: ≈80\% A and 20\% B sites. The activation energy for desorption of a CO molecule on a clean surface was found to be 183 kJ/mol with a pre-exponential factor of 3·1019s−1 on the A sites and 220 kJ/mol with a pre-exponential factor of 5·1021s−1 on the B sites. A strong dependency of the desorption energy on the Co coverage was found on the A sites, dropping to 71 kJ/mol on a CO covered surface. These values match the heat of adsorption on Pt(111) and Pt(311) reported by King et al., suggesting structural similarities of these surfaces to a Pt foil. B sites were found to be effectively blocked in the presence of oxygen. But since no significant CO2 production was observed at low temperatures, we conclude that B sites are not the active sites for the CO2 formation. This finding could be explained by the strong bonding of oxygen to those sites.}, | |

| abstract = {We have constructed first principle based six-dimensional (6D) potential energy surfaces (PESs) describing the interaction of H2 with Cu(111) obtained by interpolation of a set of density functional theory (DFT) total energy data. The DFT calculations have been performed within the generalized gradient approximation (GGA) framework. In applying the GGA we have tested the two exchange?correlation (XC) functionals most popular in surface science, i.e., the PW91 and RPBE functionals. The interpolation of the PW91 PES has been performed using two different methods, the corrugation reducing procedure (CRP), which has been proven to be one of the most successful interpolation methods to build 6D PESs, and the modified Shepard (MS) interpolation method, a very promising method to build high dimensional (nD) PESs, which is computationally cheaper than the CRP. We show that, in spite of the difference between the CRP-PES and the MS-PES and the inaccuracies found in the latter, quantum and classical reaction and scattering probabilities obtained for both PESs are very similar. We also show that PW91 predicts higher reactivity than RPBE, due to the presence of lower energy dissociation barriers in the PW91-PES. The differences between the PW91-PES and the RPBE-PES are also reflected in the vibrational excitation and rotational excitation probabilities, and the diffraction patterns.}, | |

| abstract = {We construct a nonlocal density functional approximation with full exact exchange, while preserving the constraint-satisfaction approach and justified error cancellations of simpler semilocal functionals. This is achieved by interpolating between different approximations suitable for two extreme regions of the electron density. In a “normal” region, the exact exchange-correlation hole density around an electron is semilocal because its spatial range is reduced by correlation and because it integrates over a narrow range to −1. These regions are well described by popular semilocal approximations (many of which have been constructed nonempirically), because of proper accuracy for a slowly varying density or because of error cancellation between exchange and correlation. “Abnormal” regions, where nonlocality is unveiled, include those in which exchange can dominate correlation (one-electron, nonuniform high density, and rapidly varying limits), and those open subsystems of fluctuating electron number over which the exact exchange-correlation hole integrates to a value greater than −1. Regions between these extremes are described by a hybrid functional mixing exact and semilocal exchange energy densities locally, i.e., with a mixing fraction that is a function of position r and a functional of the density. Because our mixing fraction tends to 1 in the high-density limit, we employ full exact exchange according to the rigorous definition of the exchange component of any exchange-correlation energy functional. Use of full exact exchange permits the satisfaction of many exact constraints, but the nonlocality of exchange also requires balanced nonlocality of correlation. We find that this nonlocality can demand at least five empirical parameters, corresponding roughly to the four kinds of abnormal regions. Our local hybrid functional is perhaps the first accurate fourth-rung density functional or hyper-generalized gradient approximation, with full exact exchange, that is size-consistent in the way that simpler functionals are. It satisfies other known exact constraints, including exactness for all one-electron densities, and provides an excellent fit to the 223 molecular enthalpies of formation of the G3/99 set and the 42 reaction barrier heights of the BH42/03 set, improving both (but especially the latter) over most semilocal functionals and global hybrids. Exact constraints, physical insights, and paradigm examples hopefully suppress “overfitting.”}, | |

It is found that H forms an essentially covalent bond with the metal, whereas O and OH form a largely ionic bond. The O and OH adsorbates prefer the high coordination three-fold hollow site on all metals: no such clear trend for H is found, the adsorption energy for on-top and hollow sites being comparable for most metals, especially on transition metals. The O and OH adsorbates are attracted towards, and donate some electronic charge to, the surface when a positive electric field (electrode potential) is applied, whereas the effect of an applied field on H adsorption is much smaller. We also show how the trends in the OH adsorption energies on different metals, as compared with O adsorption, can be explained by a weaker covalent interaction and a stronger Pauli repulsion of the OH with the metal d electrons.}, | |

Our calculations reveal strong changes in the PES upon atomic N adsorption, which becomes much more corrugated than that of the clean Ag(111) surface. This apparently contradicts a key experimental finding made for atoms with incident average energy ?Ei? = 4.3 eV, namely that the N reflection dynamics on Ag(111) at N saturation coverage are quantitatively similar to those of clean Ag(111). In good agreement with the experiments, we find that the stronger PES corrugation of the N-covered Ag(111) surface does not affect the angular distribution of the scattered N atoms with that ?Ei? value. However, discrepancies are found in the final-to-initial average energy ratios, ?Ef?/?Ei?, at grazing outgoing angles. Upon examination of the adsorption trajectories, it can be inferred that gas N is likely to react with adsorbed N. MD shows that this ?pickup? mechanism is particularly effective for slow atoms and could be behind the experimental ?Ef?/?Ei? values.}, | |

| abstract = {We used density functional theory calculations to examine the initial stages of oxidation of the Pt(111) surface. Consistent with prior studies, our calculations predict that oxygen atoms adsorb on fcc sites and form p(2×2) and p(2×1) structures at coverages of 0.25 and 0.50 ML, respectively. In addition to various surface configurations of oxygen on fcc sites, we examined subsurface oxygen and clustering of oxygen atoms on the surface. We find that subsurface oxygen is not the precursor to the oxidation of the Pt(111) surface. Instead, we predict a strong preference for the formation and growth of one-dimensional Pt oxide chains within the p(2×1) structure. In particular, at coverages above 0.50 ML, additional oxygen atoms prefer to aggregate between the close-packed oxygen rows formed by the p(2×1) structure and induce large buckling (∼1.8 Å) and modification of the charge of the surface Pt atoms. The result is an oxide compound with threefold and fourfold Pt-O coordination that grows as a one-dimensional chain running parallel to the oxygen rows of the p(2×1) structure. Furthermore, half of the oxygen atoms in the Pt oxide chains reside near hcp sites, contrary to some reports that oxygen atoms reside only on the fcc sites on Pt(111). Our results agree well with a recent scanning tunneling microscopy study and suggest a precursor mechanism to the oxidation of metal surfaces involving Pt oxide chain formation and growth on terraces at moderate oxygen coverages. Our results should have important implications to current models of NO and CO oxidation on Pt(111) and potentially on studies of the initial oxidation of other transition-metal and bimetallic surfaces.}, | |

Specifically, studying a particular system, we attempt to construct a phenomenological theory describing the interplay between mechanical work and heat that takes place during operations through which the system undergoes transitions between non-equilibrium steady states. We find that, in contrast to the case of the equilibrium theory, apparently, there exists no systematic way within a phenomenological formulation to describe the work done by the system during such operations. With this observation, we conclude that the attempt to construct a thermodynamic theory of non-equilibrium steady states in analogy to the equilibrium theory has limited prospects for success and that the pursuit of such a theory should be directed elsewhere.}, | |

| abstract = {Pd(111) has recently been shown to exhibit a propensity to form a subnanometer thin surface oxide film already well before a full monolayer coverage of adsorbed O atoms is reached on the surface. Aiming at an atomic-scale understanding of this finding, we study the initial oxygen incorporation into the Pd(111) surface using density-functional theory. We find that oxygen incorporation into the sub-surface region starts at essentially the same coverage as formation of the surface oxide. This implies that the role of sub-surface oxygen should be considered as that of a metastable precursor in the oxidation process of the surface. The mechanisms found to play a role towards the ensuing stabilization of an ordered oxidic structure with a mixed on-surface/sub-surface site occupation follow a clear trend over the late 4d transition metal series, as seen by comparing our data to previously published studies concerned with oxide formation at the basal surface of Ru, Rh, and Ag. The formation of a linearly aligned O-TM-O trilayered structure (TM=Ru,Rh,Pd,Ag), together with an efficient coupling to the underlying substrate seem to be key ingredients in this respect.}, | |

These Pd oxide species preferentially form a thin layer at the particle/support interface, stabilized by the iron-oxide support. Their formation and reduction is fully reversible.

In consequence, the Pd interface oxide layer acts as an oxygen reservoir, the capacity of which by far exceeds the amount of chemisorbed oxygen on the metallic surface.{\textless}br/{\textgreater}Additionally, Pd surface oxides can also be formed at temperatures above 500 K. The extent of surface oxide formation critically depends on the oxidation temperature. This effect is addressed to different onset temperatures for oxidation of the particle facets and sites. It is shown that the presence of Pd surface oxides sensitively modifies the adsorption and reaction properties of the model catalyst, i.e. by lowering the CO adsorption energy and CO oxidation probability. Still, a complete reduction of the Pd surface oxides can be obtained by extended CO exposure, fully reestablishing the metallic Pd surface.{\textless}/p{\textgreater}}, | |

| abstract = {Adsorbate interactions affect both the energies and arrangements of adsorbates on surfaces and consequently influence rates of surface chemical reactions. Here we examine these effects for a rate-limiting O2 dissociation model of catalytic NO oxidation on the late transition metals. We report periodic density functional theory calculations of atomic oxygen adsorption on the (0001) facets of Ru, Os, and Co, and the (111) facets of Rh, Ir, Ni, Pd, Pt, Cu, Ag, and Au and correlate these results using cluster expansion (CE) representations. We use grand canonical Monte Carlo simulations implementing these CE Hamiltonians to determine both the number and energetics of first-nearest-neighbor binding site vacancies available for the dissociative adsorption of O2 at conditions representative of catalytic NO oxidation. We estimate steady-state turnover frequencies and compare results to predictions using non-interacting adsorbates. We show that coverage dependence manifests itself in both the energetics and statistical availability of reaction sites and causes rates to deviate substantially from the coverage-independent limit.}, | |

| abstract = {The kinetics of the oxygen reduction reaction (ORR) was investigated in acid solutions on Pt monolayers that were deposited on carbon-supported Ru nanoparticles using the rotating disk electrode technique. The Pt mass and specific ORR activities greatly depend on the number of Pt monolayers, and the optimum activity occurs with two Pt monolayers. Density functional theory calculations showed that Pt overlayers destabilize O* and OH* with respect to pure Pt, leading to more favorable hydrogenation kinetics. However, with only a single Pt overlayer, the destabilization is too much, and O?O bond breaking becomes rate limiting. Two to three Pt monolayers supported on the Ru core of our nanoparticles lead to increased activity. This work demonstrates that one can modulate the ORR activity of Pt monolayers supported on other metals by eliminating a part of the ligand effect by increasing the thickness of the Pt shell on top of the supporting metal surface.}, | |

| abstract = {Kinetic and isotopic methods were used to establish the identity and kinetic relevance of elementary steps and the effects of cluster size for NO oxidation on supported Pd catalysts. O2 activation on vacancies within nearly saturated oxygen adlayers is the sole kinetically relevant step. Water, present in combustion effluents, inhibits NO oxidation via reversible adsorption on vacancies to form unreactive OH species. The coverage and chemical potential of oxygen are determined by the NO2/NO ratios prevalent during catalysis; they are rigorously described by O2 virtual pressures accessible to measurement. At a given oxygen chemical potential, O2 activation during 16O2-18O2 exchange and NO oxidation occurs at similar rates, indicating that NO-assisted O2 activation is not required for NO oxidation turnovers. These findings confirm the rigor and relevance of O2 virtual pressure as a measurable surrogate for the oxygen chemical potential during catalysis, as well as the role of mobile oxygen species, which allow O2 dissociation to occur on isolated vacancies. Oxygen chemical potentials prevalent during NO oxidation cause active clusters to exist as PdO at all relevant conditions, consistent with steady-state turnover rates that are insensitive to reductive or oxidative treatments. NO oxidation turnover rates decrease as PdO clusters become smaller because of stronger oxygen binding and lower vacancy concentrations in small clusters. The catalytic consequences of size are similar on PdO and Pt clusters, despite their different oxidation state, consistent with a common requirement for surface vacancies in O2 activation steps on both catalysts. Such requirements lead to strong NO2 inhibition effects and to a marked increase in NO oxidation rates when NO2 adsorbents, present as physical mixtures, decrease NO2 concentrations near active sites.}, | |

| abstract = {The interaction of NO with a flat and two stepped Rh(111) surfaces was studied at different temperatures by monitoring in situ the evolution of the O 1s and N 1s spectra during NO exposure using fast high resolution x-ray photoelectron spectroscopy. The O 1s and N 1s intensities and binding energies were used to fingerprint the types of adsorbed species and to monitor the changes in their coverage and adsorption sites. From the O 1s intensity during uptake on Rh(533) it was determined that the NO initial sticking coefficient is temperature independent between 330 and 490 K. The N 1s spectra revealed the consecutive appearance of two atomic nitrogen species. By comparing the N 1s spectra on Rh(533) with those measured on Rh(111) and Rh(311) these species were attributed to adsorption on terrace sites, N T , and step sites, N S . N T is the only species formed in the initial stage of adsorption, whereas the N S species appears later on. This finding indicates that the NO dissociation occurs on terrace adsorption sites in the low coverage regime (total coverage ⩽0.25 monolayers). The stepped surfaces conserve a high reactivity at higher coverages because the NO dissociation continues on the steps after the terraces have been filled. The abrupt changes in the NO dissociation probability with increasing adsorbate coverage are discussed in terms of destabilization of the N T species by repulsive interactions and of subsequent compression of the adsorbed O and NO.}, | |

The CO2 reduction activities of these electrodes exhibited a strong dependence on the initial thickness of the Cu2O layer. Thin Cu2O layers formed by annealing at 130 °C resulted in electrodes whose activities were indistinguishable from those of polycrystalline Cu. In contrast, Cu2O layers formed at 500 °C that were ≥??3 ?m thick resulted in electrodes that exhibited large roughness factors and required 0.5 V less overpotential than polycrystalline Cu to reduce CO2 at a higher rate than H2O. The combination of these features resulted in CO2 reduction geometric current densities {\textgreater}1 mA/cm2 at overpotentials {\textless}0.4 V, a higher level of activity than all previously reported metal electrodes evaluated under comparable conditions. Moreover, the activity of the modified electrodes was stable over the course of several hours, whereas a polycrystalline Cu electrode exhibited deactivation within 1 h under identical conditions. The electrodes described here may be particularly useful for elucidating the structural properties of Cu that determine the distribution between CO2 and H2O reduction and provide a promising lead for the development of practical catalysts for electrolytic fuel synthesis.}, | |

| abstract = {The gradient geometry‐optimization procedure is reformulated in terms of redundant internal coordinates. By replacing the matrix inverse with the generalized inverse, the usual Newton–Raphson–type algorithms can be formulated in exactly the same way for redundant and nonredundant coordinates. Optimization in redundant coordinates is particularly useful for bridged polycyclic compounds and cage structures where it is difficult to define physically reasonable redundancy‐free internal coordinates. This procedure, already used for the geometry optimization of porphine, C20N4H14, is illustrated here at the ab initio self‐consistent‐field level for the four‐membered ring azetidine, for bicyclo[2.2.2]octane, and for the four‐ring system C16O2H22, the skeleton of taxol.}, | |

| The results obtained revealed that CuO underwent solid–solid interaction with Fe2O3 at temperatures starting from 800 °C producing nanocrystalline CuFe2O4. The degree of propagation of this reaction increases progressively by increasing both the calcination temperature and the amounts of dopant added. The promotion effect of MgO and Al2O3 towards the ferrite formation was attributed to an effective increase in the mobility of the various reacting cations.

| volume = {33}, | |
| abstract = {Anlasslich der Verleihung des ersten Deutschen Buchpreises 2005 an Arno Geiger fur seinen Familienroman Es geht uns gut‘ (2005) kommentierte Bernhard Jahn, der seit der Wende spurbare Trend zum Familienroman sei offensichtlich bestatigt worden. Er stellte auch fest, dass die ‘neuen’ Familienromane Generationenromane seien, die chronologisch mindestens drei Generationen umfassten, wobei sich die Familie als genealogische Kette erweise. Die zeitliche Ausweitung bringt in den Familienromanen die diachrone Dimension des Generationenbegriffs ins Spiel, die seit dem Karl Mannheimschen Generationenkonzept, das den besonderen Akzent auf die synchrone Seite legt, weitgehend ignoriert worden ist. Somit werden die Texte, die sich mit den familiaren Generationenproblemen auseinandersetzen, in der vorliegenden Arbeit als Generationenromane verstanden. Heutzutage fuhren wir kein GroSSfamilienleben mehr, sondern bevorzugen uber das Kleinfamiliare hinaus sogar das ‘Single-Leben’. In der Tat standen die Single- Existenz und die damit einhergehenden Probleme in den vorher beliebten Popromanen im Mittelpunkt. Woran liegt dann an die heutige Renaissance der Generationenromane? Die vorliegende Arbeit versucht, am Beispiel Arno Geigers Es geht uns gut‘ aufzuzeigen, was fur Bedeutungen und Funktionen die Familie in den ‘neuen’ Generationenromanen hat. In Arno Geigers Es geht uns gut‘ hat Philipp, die familiar unambitionierte Hauptfigur, ein Trauma vor verbindlichen Beziehungen und will das von seiner GroSSmutter geerbte Haus sofort auflosen. Er geht dabei in doppelter Weise vor: Zum Ausraumen des Dachbodens, der sich spater im von Alma erzahlten Kapitel als ‘Speicher’ fur Familientraumata erweist, engagiert er zwei Schwarzarbeiter aus der Ukraine. Aber er selbst bleibt nur an der Vortreppe der Villa und beschaftigt sich mit dem Nachdenken und Schreiben uber seine Familie. Dabei wird ihm immer bewusster, dass er ein Teil der genealogischen Familienkette ist, und sein ‘Jetzt’ mit der vergangenen Familiengeschichte eng zusammenhangt. Auch wenn Philipps Fertigstellung seiner Familiengeschichte im Romantext Arno Geigers nicht erwahnt wird, konnte man den Eindruck gewinnen, als ware Es geht uns gut‘ ein von Philipp verfasster Roman, weil Philipp unter anderem auch Schriftsteller ist, es in den Rahmengeschichten fast nur um Philipps Nachdenken und Notizen geht, und acht ‘historische Kapitel’ dazwischen eingefugt sind. Die durch die Retrospektive gelungene Familienrekonstruktion lasst ihn seine Identitat verstarken, so dass er am Ende in die ‘Zukunft’ sowie ins ‘Fremde’ fortschreiten und sogar die zwei ‘fremden’ Schwarzarbeiter als ‘Gefahrten’ aufnehmen kann. So konnte man feststellen, dass die Familie in Es geht uns gut‘ nicht nur als Ort gilt, wo es zwischenmenschliche Konflikte gibt, aus denen Traumata entstehen, und die dann von Generation zu Generation unterschwellig weitervererbt werden, sondern auch als Konservierungsort, an dem man die Moglichkeiten bekommt, sich der Familie gegenuberzustellen, dadurch seine Identitat zu bestatigen oder neu zu entdecken, und schlieSSlich damit die Zwiste beizulegen.}, | |

| abstract = {The interaction of hydrogen with palladium surfaces represents one of the model systems for the study of the adsorption and absorptionat metal surfaces.Theoretical gas-surface dynamics studies have usually concentrated on the adsorptiondynamics on clean surfaces. Only recently it has become possible, based on advances in the electronic structure codes and improvements in the computer power, to address the much more complex problem of the adsorptiondynamics on precoveredsurfaces. Here, I present ab initiomolecular dynamics (AIMD) simulations based on periodic density functional theory(DFT) calculations of the adsorption of H2 on hydrogen-precovered Pd(100) for a broad variety of different hydrogen coverage structures. The stability of the adsorbate structures and the adsorptiondynamics are analyzed in detail. Calculated sticking probabilities are larger than expected for pure site-blocking consistent with experimental results. It turns out that the adsorptiondynamics on the strongly corrugated surfaces depends sensitively on the dynamic response of the substrate atoms upon the impact of the impinging H2 molecules. In addition, for some structures the adsorption probability was evaluated as a function of the kinetic energy.Adsorbate structures corresponding to the same coverage but with different arrangements of the adsorbed atoms can lead to a qualitatively different dependence of the adsorption probability on the kinetic energy changing also the order of the preferred structures, as far as the adsorption is concerned, as a function of the kinetic energy. This indicates that dynamical effects such as steering and dynamical trapping play an important role in the adsorption on these precovered substrates.}, | |

| abstract = {An approximately self-consistent crystal potential is constructed for Si from a superposition of free-atom core and a sampling of crystal valence band charge densities. Valence-core exchange is calculated directly from core wave functions while valence-valence exchange is included using momentum-independent and momentum-dependent approximations taken from the results for a free-electron gas. The resulting crystal potential is surprisingly similar to one previously obtained by Woodruff from a superposition of free-atom charge densities. The calculated valence wave functions in the core region differ substantially from those of Woodruff because of the variational method used by him to calculate wave functions in that region. As a result the calculated energy gap is changed from Woodruff's value of 4 ev to about 1.5 ev, in substantially better agreement with the experimental value (1.1 ev). The various uncertainties in the calculation are listed; it is concluded that the relative position of levels near the band gap should be correct to within about 1 ev. Effective masses are also calculated and compared with experiment; the agreement is quite good.}, | |

| abstract = {Hamilton population (HP) analysis—a bond-by-bond partitioning of the electronic energy—is used to elucidate the physical mechanisms by which direct (through-space) and surface-mediated interactions between adsorbates are propagated in ordered CO, NO and mixed CO/NO phases on the Pd(1 1 1) surface. Analysis of ( 3 × 3 ) R 30 ° -CO and NO phases at one-third coverage, c(4 × 2)-2CO, 2NO, and mixed CO/NO phases at half-coverage, and p(2 × 2)-3CO and 3NO phases at high (0.75 ML) coverage demonstrates that, in each case, the interaction between neighboring adsorbates is principally surface-mediated. Within the HP description, direct interactions between neighboring adsorbates are found to be of little consequence, even at high (0.75 ML) adsorbate coverages. At each coverage, the surface-mediated interaction between adsorbates primarily results from a reduction in surface–adsorbate bonding that, in turn, results from the competition between neighboring adsorbates for bonding to individual surface atoms. The magnitude of the surface-mediated interaction is shown to be strongly influenced by the relative orientation of the adsorbates about intervening surface atoms. As such, the surface-mediated interaction between adsorbates is not found to be a simple function of adsorbate separation. The reduction in surface–adsorbate bonding about shared surface atoms is shown to be influenced by the extent to which neighboring adsorbates compete for σ and π bonding with the intervening surface atoms. The extent to which the interaction between neighboring CO and/or NO molecules is mediated by Pd–Pd bonds within the surface is also shown to be a function of the respective ability of CO and NO to act as σ-donors and π-acceptors.}, | |

The theory thus constructed generalizes thermostatics and linear irreversible thermodynamics into the realm of nonlinear irreversible processes. In this theory the extended Gibbs relation and the entropy balance equation appear as a pair of mutually consistent equations under the postulates made. An equivalent theory is also formulated by replacing one of the postulates with another that is basically a variational principle. The variational principle yields the evolution equations for fluxes as the Euler equations that extremize the variational functional postulated. The local form of the extremized variational functional is the entropy balance equation for the irreversible processes in the system. Some further consequences of the theory are also considered. For example, nonequilibrium specific heats are shown to be at least quadratic functions of fluxes and reduce to the equilibrium specific heats in the limit of vanishing fluxes. In order to illustrate an example of possible applications, we have considered nonlinear transport processes in fluids. The connections of the present theory with other theories are discussed.}, | |

In an equivalent description such layers may be regarded as a mixture of phase and anti-phase domains of a lower coverage structure separated by regularly spaced domain walls (solitons), at which the local CO density is higher. Due to the flat potential energy surface the molecules at the domain walls can adjust to the repulsive CO-CO interaction by moving off the high symmetry sites. The soliton model has the advantage of providing a convenient description of the formation of such phases and of the transitions from one phase to another. In the present paper low energy electron diffraction (LEED) and infrared spectroscopy are used to illustrate these phenomena in the adsorption systems Pt111-CO and Pd111-CO.}, | |

Pd and Rh catalysts individually exhibit an opposite trend in the thermal sintering behavior with respect to the aging atmosphere. Under oxidizing conditions, the Pd catalyst becomes more resistant to sintering in higher O2 concentrations, whereas the Rh catalyst reveals the opposite behavior, regardless of the aging temperature. Physicochemical characterizations by using TGA and CO chemisorption have indicated that the state of Pd (PdO vs. Pd0) and Rh (Rh2O3 vs. Rh0) on the catalyst surface formed during the thermal aging plays an important role for determining the trend of thermal sintering; the positive effect of the O2 concentration on Pd sintering is attributable primarily to the formation of PdO, while the main cause for severe deactivation of the Rh catalyst under oxidizing conditions is the diffusion of Rh2O3 into the support along with the agglomeration of Rh particles.}, | |

Reaction pathways on both surfaces at two different coverages have been studied. It is found that the reaction pathways on both surfaces possess crucial common features despite the fact that they have different surface symmetries. Having determined reaction barriers in these systems, we find that the reaction on Pd(111) is strongly coverage dependent. Surface coverages, however, have little effect on the reaction on Pd(100).

| abstract = {We present total-energy, force, and electronic-structure calculations for Na and K adsorbed in various geometries on an Al(111) surface. The calculations apply density-functional theory together with the local-density approximation and the ab initio pseudopotential formalism. Two adsorbate meshes, namely, (√3 × √3 )R30° and (2×2), are considered and for each of them the geometry of the adlayer relative to the substrate is varied over a wide range of possibilities. By total-energy minimization we determine stable and metastable geometries. For Na we find for both adsorbate meshes that the ordering of the calculated binding energies per adatom is such that the substitutional geometry, where each Na atom replaces a surface Al atom, is most favorable and the on-top position is most unfavorable. The (√3 × √3 )R30° structure has a lower energy than the (2×2) structure. This is shown to be a substrate effect and not an effect of the adsorbate-adsorbate interaction. In contrast to the results for Na, we find for the (√3 × √3 )R30° K adsorption that the calculated adsorption energies for the on-top, threefold hollow, and substitutional sites are equal within the accuracy of our calculation, which is ±0.03 eV. The similarity of the energies of the on-surface adsorption sites is explained as a consequence of the bigger size of K which implies that the adatom experiences a rather small substrate electron-density corrugation. Therefore for potassium the on-top and hollow sites are close in energy already for the unrelaxed Al(111) substrate. Because the relaxation energy of the on-top site is larger than that of the threefold hollow site both sites receive practically the same adsorption energy. The unexpected possibility of surface-substitutional sites is explained as a consequence of the ionic nature of the bonding which, at higher coverages, can develop strongest when the adatom can dive into the substrate as deep as possible. The interesting result of the studied systems is that the difference in bond strengths between the ‘‘normal’’ and substitutional geometries is sufficiently large to kick out a surface Al atom.}, | |

Oxygen adsorption at 300 K was studied for coverages up to 0.5, while coadsorption with CO was studied in the temperature range of 80 to 450 K, and O and CO coverages of 0 to 0.25 and 0 to 0.8, respectively. Oxygen adsorbed into p(2 × 2) islands for coverages in excess of 0.05 and yielded a fully developed p(2 × 2) structure for monolayer coverage at 300 K. The p(2 × 2)O pattern was gradually replaced by a c(2 × 2)O structure as the oxygen coverage was increased to 0.5. Oxygen desorption occurred in three temperature programmed desorption states at 840, 730, and 695 K. The highest temperature state was populated at all coverages, whereas the 730 and 695 K states appeared as the oxygen coverage exceeded 0.25 and 0.36, respectively. The 695 K state was unusually narrow suggesting attractive interactions in the oxygen adlayer for coverages of 0.36 to 0.5. For the surface precovered with 0.25 monolayer of oxygen, CO adsorption at 80 K caused a disordering of the p(2 × 2)O structure. At lower oxygen coverages CO initially adsorbed at sites apart from the oxygen domains, but also adsorbed within oxygen islands upon filling of the exterior sites. CO adsorption in the interior of the islands produced a directly interacting CO---Pd---O complex characterized by a CO stretching frequency of 2125 cm-1. Reaction-limited CO2 evolution occurred in three states; viz. reaction of CO with (1) isolated oxygen atoms or p(2 × 2)O islands at 420 K, (2) disordered oxygen islands at 360 K, and (3) by a low temperature reaction between 100 and 310 K due to the CO---Pd---O complexes. No evidence of molecularly adsorbed CO2 or carbonate (CO3) reaction intermediates was observed by EELS at 80 K.{\textless}/p{\textgreater}}, | |

In the present work, we show that the Zhang and Yang functional (revPBE) also improves the chemisorption energetics of atoms and molecules on transition-metal surfaces. Our test systems comprise atomic and molecular adsorption of oxygen, CO, and NO on Ni(100), Ni(111), Rh(100), Pd(100), and Pd(111) surfaces. As the revPBE functional may locally violate the Lieb-Oxford criterion, we further develop an alternative revision of the PBE functional, RPBE, which gives the same improvement of the chemisorption energies as the revPBE functional at the same time as it fulfills the Lieb-Oxford criterion locally.}, | |

| abstract = {We review and provide a perspective on multiscale modeling of catalytic reactions with emphasis on mechanism development and application to complex and emergent systems. We start with an overview of length and time scales, objectives, and challenges in first-principles modeling of reactive systems. Subsequently, we review various methods that ensure thermodynamic consistency of mean-field microkinetic models. Next, we describe estimation of reaction rate constants via quantum mechanical and statistical–mechanical methods as well as semi-empirical methods. Among the latter, we discuss the bond-order conservation method for thermochemistry and activation energy estimation. In addition, we review the newly developed group-additivity method on adsorbate/metal systems and linear free energy or Brønsted–Evans–Polanyi (BEP) relations, and their parameterization using DFT calculations to generate databases of activation energies and reaction free energies. Linear scaling relations, which can enable transfer of reaction energetics among metals, are discussed. Computation-driven catalyst design is reviewed and a new platform for discovery of materials with emergent behavior is introduced. The effect of parameter uncertainty on catalyst design is discussed; it is shown that adsorbate–adsorbate interactions can profoundly impact materials design. Spatiotemporal averaging of microscopic events via the kinetic Monte Carlo method for realistic reaction mechanisms is discussed as an alternative to mean-field modeling. A hierarchical multiscale modeling strategy is proposed as a means of addressing (some of) the complexity of catalytic reactions. Structure-based microkinetic modeling is next reviewed to account for nanoparticle size and shape effects and structure sensitivity of catalytic reactions. It is hypothesized that catalysts with multiple sites of comparable activity can exhibit structure sensitivity that depends strongly on operating conditions. It is shown that two descriptor models are necessary to describe the thermochemistry of adsorbates on nanoparticles. Multiscale and accelerated methods for computing free energies in solution, while accounting explicitly for solvent effects in catalytic reactions, are briefly touched upon with the acid catalyzed dehydration of fructose in water as an example. The above methods are illustrated with several reactions, such as the CO oxidation on Au; the hydrogenation of ethylene and hydrogenolysis of ethane on Pt; the glycerol decomposition to syngas on Pt-based materials; the NH3 decomposition on single metals and bimetallics; and the dehydration of fructose in water. Finally, we provide a summary and outlook.}, | |

Presently, the fastest reported methods use binary trees to search through a list of rates in O(log2M) time, where M is the number of rates. These methods are applicable to an arbitrary set of rates, but typical KMC bond-counting schemes involve only a finite set of distinct rates. This allows one to construct a faster list-based algorithm with a computation time that is essentially independent of M. It is found that this algorithm typically reduces computation time by between 30\% and 50\% for typical simulations, with this factor increasing for larger simulations.}, | |

| abstract = {Using the Monte Carlo technique, we simulate the kinetics of temperature-programmed associative desorption (TPD) of oxygen atoms from Pt(111) at coverages below a quarter of the monolayer. Oxygen atoms are assumed to be adsorbed on a triangular lattice of fcc sites. Nearest-neighbour (nn) O–O lateral interactions, ϵ1, are considered to be strongly repulsive so that there are no occupied nn sites. The second- and third-nn interactions, ϵ2≥0 and ϵ3⩽0 (positive values correspond to repulsion), are chosen to reproduce the p(2×2) ordering of oxygen atoms. Comparison between the simulations and experimental TPD spectra for the O/Pt(111) system is supporting repulsive O–O interactions. More specifically, the TPD spectra are hard to reconcile with the assumption that the O–O lateral interactions are partly attractive and that this attraction is sufficiently strong to stabilize the p(2×2) islands at low coverages and relatively high temperatures (∼400 K). The consequence of this finding for interpretation of available experimental data on oxygen diffusion on Pt(111) is discussed in detail.}, | |

| abstract = {Interpolation methods such as the nudged elastic band and string methods are widely used for calculating minimum energy pathways and transition states for chemical reactions. Both methods require an initial guess for the reaction pathway. A poorly chosen initial guess can cause slow convergence, convergence to an incorrect pathway, or even failed electronic structure force calculations along the guessed pathway. This paper presents a growing string method that can find minimum energy pathways and transition states without the requirement of an initial guess for the pathway. The growing string begins as two string fragments, one associated with the reactants and the other with the products. Each string fragment is grown separately until the fragments converge. Once the two fragments join, the full string moves toward the minimum energy pathway according to the algorithm for the string method. This paper compares the growing string method to the string method and to the nudged elastic band method using the alanine dipeptide rearrangement as an example. In this example, for which the linearly interpolated guess is far from the minimum energy pathway, the growing string method finds the saddle point with significantly fewer electronic structure force calculations than the string method or the nudged elastic band method. © 2004 American Institute of Physics.}, | |

| abstract = {High resolution photoelectron spectroscopy and density functional theory calculations have been used to study the composition of clean and oxidized Pd75Ag25(100). The results for the clean surface confirm earlier reports of surface segregation by Wouda et al. (1998), where the top most layers are rich in Ag. The Pd 3d core level component from the surface region is observed at higher binding energies than the contribution from the bulk which is found to be a signature of Pd embedded in Ag. Low energy electron diffraction and scanning tunneling microscopy measurements reveal that oxidation of the Pd75Ag25(100) surface results in a 5 × 5 R 27 ° -O structure similar to the one reported for Pd(100). The calculations suggest that the stable structure is a PdO(101) monolayer supported on a (100) surface rich in Ag at the interface to the stoichiometric alloy. The calculated core level shifts for the oxidized surface are in good agreement with the experimental observations.}, | |

| abstract = {Single-particle states in electronic Bloch bands form a Riemannian manifold whose geometric properties are described by two gauge invariant tensors, one being symmetric the other being antisymmetric, that can be combined into the so-called Fubini-Study metric tensor of the projective Hilbert space. The latter directly controls the Hall conductivity. Here we show that the symmetric part of the Fubini-Study metric tensor also has measurable consequences by demonstrating that it enters the current noise spectrum. In particular, we show that a non-vanishing equilibrium current noise spectrum at zero temperature is unavoidable whenever Wannier states have non-zero minimum spread, the latter being quantifiable by the symmetric part of the Fubini-Study metric tensor. We illustrate our results by three examples: (1) atomic layers of hexagonal boron nitride, (2) graphene, and (3) the surface states of three-dimensional topological insulators when gaped by magnetic dopants.}, | |

| abstract = {The specific CO oxidation activity of palladium versus palladium oxide is still controversially discussed. In this study, 5 wt. \% Pd-γ-Al2O3 catalysts were utilized to investigate the effect of the palladium oxidation state on the CO oxidation activity. Comprehensive in situ and ex situ characterization of different alumina supported PdOx (x = 0−1) phases (by HR-TEM, XRD, and FTIR spectroscopy), combined with kinetic measurements and DFT calculations of CO adsorption, allowed us to assess the catalytic activity of the different PdOx (x = 0−1) species: Supported Pd0 and substoichiometric PdOx{\textless}1 exhibited comparable high activities, due to a rapid reduction of PdOx{\textless}1 to Pd upon CO exposure. PdO nanoparticles showed a lower catalytic activity resulting from their higher stability against reduction by CO. The limited extent of oxidation of Pd under typical reaction conditions together with the facile reduction of substoichiometric PdOx{\textless}1 suggest that the active phase present under the current reaction conditions is oxygen-covered metallic Pd.}, | |

Electron beam dissociation of adsorbed NO was used to cleanly prepare N atom coverages between 0.05 and 0.5 monolayers. By using isotopically labeled NO and N reactants, we determined that NO and N react, under our conditions, to form only N2O. In contrast to previous reports, we see no evidence that suggests that NO and N can react to form N2 as a product. In complementary experiments, we have completed computer modeling of an NO temperature-programmed desorption experiment. These simulations show that NO dissociation rates in the high NO coverage limit are as much as 500 times slower than previously reported dissociation in the low coverage limit.}, | |

The original method has been shown to satisfy detailed balance at the coarse scale and to provide a good representation of various equilibrium properties in both atomic and molecular systems. However, we show here that the original method is inconsistent with non-equilibrium trajectories generated by full-resolution Monte Carlo simulations, which, under certain conditions, have been shown to correspond to Langevin dynamics. The modified coarse-grained method is generated by simultaneously biasing the forward and backward transition probability for every possible move, thereby preserving the detailed balance of the original method. The resulting coarse-grained Monte Carlo simulations are shown to provide trajectories that are consistent with overdamped Langevin (Smoluchowski) dynamics using a sequence of simple non-equilibrium examples. We first consider the purely diffusional spreading of a Gaussian pulse of ideal-gas particles and then include an external potential to study the influence of drift. Finally, we validate the method using a more general situation in which the particles interact via a Lennard-Jones interparticle potential.}, | |

| abstract = {Experimental studies employing surface science methods indicate that kinetic oscillations, chaos, and pattern formation in heterogeneous catalytic reactions often result from the interplay of rapid chemical reaction steps and relatively slow complementary processes such as oxide formation or adsorbate-induced surface restructuring. In general, the latter processes should be analysed in terms of theory of phase transitions. Therefore, the conventional mean-field reaction–diffusion equations widely used to describe oscillations in homogeneous reactions are strictly speaking not applicable. Under such circumstances, application of the Monte Carlo method becomes almost inevitable. In this review, we discuss the advantages and limitations of employing this technique and show what can be achieved in this way. Attention is focused on Monte Carlo simulations of CO oxidation on (1\&\#xa0;0\&\#xa0;0) and (1\&\#xa0;1\&\#xa0;0) single-crystal Pt and polycrystal Pt, Pd and Ir surfaces and of NO reduction by CO and H2 on Pt(1\&\#xa0;0\&\#xa0;0). CO oxidation on supported nanometre-sized catalyst particles and NO reduction on composite catalysts are also discussed. The results show that with current computer facilities the MC technique has become an effective tool for analysing temporal oscillations and pattern formation on the nanometre scale in catalytic reactions occurring on both single crystals and supported particles.}, | |

| abstract = {Rational design and advancement in materials science will ultimately rely on an atomic-scale understanding of the targeted functionality. Corresponding modeling must then address the behavior of electrons and the resulting interactions that govern the elementary processes among the atoms and molecules. Modern electronic structure theory methods like density-functional theory (DFT) have matured, allowing a description that is often already accurate enough to allow for a modeling with predictive character. These techniques are referred to as first-principles (or in latin: ab initio) to indicate that they do not rely on empirical or fitted parameters, which then makes them applicable for a wide range of realistic conditions. A predictive modeling of materials properties requires a consistent treatment in the wide hierarchy of scales from the electronic level to macroscopic lengths and times. The central idea of ab initio atomistic thermodynamics is to employ the information on the potential energy surface provided by modern electronic structure theories, in order to calculate appropriate thermodynamic potential functions. With the latter, macroscopic system properties at finite temperatures can immediately be discussed. At surfaces, such a thermodynamic description can be particularly useful, since it provides the possibility to suitably divide the total system into smaller subsystems that are mutually (or partly) in equilibrium with each other. This way, infinite, but homogeneous parts of the system like bulk or surrounding gas phase can be efficiently represented by corresponding reservoirs, which e.g. allows to address surfaces in contact with realistic environments. In this tutorial text we have focused on a very simple realization of this general scheme, namely the direct screening approach, to determine the equilibrium geometry and composition of a solid surface in contact with a given environment at finite temperature and pressure.}, | |

The method extends the density-functional codes SIESTA and TRANSIESTA that use atomic basis sets. The inelastic conductance characteristics are calculated using the nonequilibrium Green’s function formalism, and the electron-phonon interaction is addressed with perturbation theory up to the level of the self-consistent Born approximation. While these calculations often are computationally demanding, we show how they can be approximated by a simple and efficient lowest order expansion. Our method also addresses effects of energy dissipation and local heating of the junction via detailed calculations of the power flow. We demonstrate the developed procedures by considering inelastic transport through atomic gold wires of various lengths, thereby extending the results presented in Frederiksen et al. Phys. Rev. Lett. 93 256601 (2004)]. To illustrate that the method applies more generally to molecular devices, we also calculate the inelastic current through different hydrocarbon molecules between gold electrodes. Both for the wires and the molecules our theory is in quantitative agreement with experiments, and characterizes the system-specific mode selectivity and local heating.}, | |

It has been found that surfaces representing acidic and alkaline conditions have a significant influence on both the shape of the nanocrystals and the anatase-to-rutile transition size. The latter introduces the possibility of inducing phase transitions by changing the surface chemistry.}, | |

As expected, we find that water forms several ordered hydration layers, with the first hydration layer having water molecules aligned so that oxygen atoms are on average situated above Na sites. In an attempt to understand the dissolution of NaCl in water, we have then combined AIMD with constrained barrier searches, to calculate the dissolution energetics of Cl− and Na+ ions from terraces, steps, corners and kinks of the (100) surface. We find that the barrier heights show a systematic reduction from the most stable flat terrace sites, through steps to the smallest barriers for corner and kink sites. Generally, the barriers for removal of Cl− ions are slightly higher than for Na+ ions. Finally, we use our calculated barriers in a Kinetic Monte Carlo as a first order model of the dissolution process.}, | |

| abstract = {The indirect interaction between adatom pairs on the (100) surface of a simple-cubic tight-binding solid is investigated within a molecular-orbital approach. A general scheme for calculating the surface-density-of-states change and the interaction energy of one and two single-level adatoms is presented, and contact (and a correction) is made with Grimley's formulation. The method permits binding above surface atoms, at bridge sites, or at centered positions, and yields interaction energy as a function of band filling, adatom energy level, and a general hopping potential V between an adatom and the nearest surface atom(s). Calculations have been carried out for VWb in the range 1/12-1/2, the upper limit giving split-off states (Wb≡bandwidth). The single-atom interaction shows little dependence on binding type, in all three cases being most attractive when the Fermi energy equals the noninteracting adatom level, with a strongly V-dependent strength. For the pair interaction, one finds a strength at nearest-neighbor separation of about an order of magnitude smaller than the absorption energy of a single adatom. This interaction has an exponentiallike dropoff and sign alternations as one moves along the ⟨10⟩ direction. Under reasonable conditions, the nearest-neighbor interaction is often repulsive while the next nearest, third nearest, or fourth nearest is attractive, suggesting the patterns c(2×2), (2 × 2), and c(4×2), respectively, which are frequently observed in the adsorption of simple gases on the (100) surfaces of transition metals. On the basis of two-dimensional Ising-model calculations including second-neighbor interactions, one can estimate the strength of V from the observed disordering temperature of the adatom lattice; the result is similar to that obtained from estimates based on the heat of adsorption.}, | |

| abstract = {Existing kinetic Monte Carlo(KMC) frameworks for the simulation of adsorption, desorption,diffusion, and reaction on a lattice often assume that each participating species occupies a single site and represent elementary events involving a maximum of two sites. However, these assumptions may be inadequate, especially in the case of complex chemistries, involving multidentate species or complex coverage and neighboring patterns between several lattice sites. We have developed a novel approach that employs graph-theoretical ideas to overcome these challenges and treat easily complex chemistries. As a benchmark, the Ziff-Gulari-Barshad system is simulated and comparisons of the computational times of the graph-theoretical KMC and a simpler KMC approach are made. Further, to demonstrate the capabilities of our framework, the water-gas shift chemistry on Pt(111) is simulated.}, | |

Equilibrium geometries, dipole moments, harmonic vibrational frequencies, and atomization energies were calculated for a set of 32 small neutral molecules by six different local and gradient‐corrected DFT methods, and also by the ab initio methods Hartree–Fock, second‐order Mo/ller–Plesset, and quadratic configuration interaction with single and double substitutions (QCISD). The standard 6‐31G* basis set was used for orbital expansion, and self‐consistent Kohn–Sham orbitals were obtained by all DFT methods, without employing any auxiliary fitting techniques. Comparison with experimental results shows the density functional geometries and dipole moments to be generally no better than or inferior to those predicted by the conventional ab initio methods with this particular basis set. The density functional vibrational frequencies compare favorably with the ab initio results, while for atomization energies, two of the DFT methods give excellent agreement with experiment and are clearly superior to all other methods considered.}, | |

| abstract = {Elucidation of complex heterogeneous catalytic mechanisms at the molecular level is a challenging task due to the complex electronic structure and the topology of catalyst surfaces. Heterogeneous catalyst surfaces are often quite dynamic and readily undergo significant alterations under working conditions. Thus, monitoring the surface chemistry of heterogeneous catalysts under industrially relevant conditions such as elevated temperatures and pressures requires dedicated in situ spectroscopy methods. Due to their photons-in, photons-out nature, vibrational spectroscopic techniques offer a very powerful and a versatile experimental tool box, allowing real-time investigation of working catalyst surfaces at elevated pressures. Infrared reflection absorption spectroscopy (IRAS or IRRAS), polarization modulation-IRAS and sum frequency generation techniques reveal valuable surface chemical information at the molecular level, particularly when they are applied to atomically well-defined planar model catalyst surfaces such as single crystals or ultrathin films. In this review article, recent state of the art applications of in situ surface vibrational spectroscopy will be presented with a particular focus on elevated pressure adsorption of probe molecules (e.g. CO, NO, O2, H2, CH3OH) on monometallic and bimetallic transition metal surfaces (e.g. Pt, Pd, Rh, Ru, Au, Co, PdZn, AuPd, CuPt, etc.). Furthermore, case studies involving elevated pressure carbon monoxide oxidation, CO hydrogenation, Fischer–Tropsch, methanol decomposition/partial oxidation and methanol steam reforming reactions on single crystal platinum group metal surfaces will be provided. These examples will be exploited in order to demonstrate the capabilities, opportunities and the existing challenges associated with the in situ vibrational spectroscopic analysis of heterogeneous catalytic reactions on model catalyst surfaces at elevated pressures.}, | |

Besides the known effect of the continued d-band filling on the oxygen?metal bond strength, we also discern trends in the adsorption geometries, work functions, and electron density of states. The repulsive lateral interactions in the overlayer give rise to a pronounced reduction of the adsorption energy at higher on-surface coverages. In fact, for oxygen coverages ? {\textgreater} 0.5 monolayers, the thermodynamic equilibrium phase of O/Pd(111) is known to be a surface oxide. The calculations reported in this paper show that on-surface adlayers at such higher coverages, that may exist as metastable phases, still possess qualitatively the same surface chemical bond as that which is found at low coverages. The dependence of the surface relaxation on oxygen coverage exhibits some unexpected behavior. | |

In fact, for oxygen coverages ? {\textgreater} 0.5 monolayers, the thermodynamic equilibrium phase of O/Pd(111) is known to be a surface oxide. The calculations reported in this paper show that on-surface adlayers at such higher coverages, that may exist as metastable phases, still possess qualitatively the same surface chemical bond as that which is found at low coverages. The dependence of the surface relaxation on oxygen coverage exhibits some unexpected behavior.}, | |

| abstract = {The accelerating effect of various multivalent cations, the halogen anions and the acidity of the solution on the rate of the electrochemical reduction of CO2 on a Cu (88)–Sn (6)–Pb (6) alloy cathode was studied. In 1.5 mol L−1 HCl containing various cations, at −0.65 V vs. Ag/AgCl the rate increases with the increase of the surface charge of the cation of the supporting electrolyte in the order Na+ \< Mg2+ \< Ca2+ \< Ba2+ \< Al3+ \< Zr4+ \< Nd3+ \< La3+. In La3+ containing electrolyte the rate was two-times higher than that in the case of Na+ at the same potential. The acceleration effect was attributed to the participation of the radical anion (CO2−) in the rate determining step. The effect of the cation was somewhat higher at pH \> 4, but less pronounced at quite negative potentials (−1.7 V). This was attributed to the change of the rate-determining step of the reduction at high overpotentials. In strongly acidic solution at −0.65 V the halogen anion increases the rate in the order Cl− \< Br− \< I−, while the increase of the [H3O+] from 0.1 to 2 mol L−1 resulted to an increase in the rate by 53\%. The main products of the reduction were CH3OH, CH3CHO, HCOOH and CO. The \% current efficiency (\% CE) of CH3OH and HCOOH displayed maxima (∼35 and 28\%) at −0.6 and −0.65 V respectively. The \%CE of CH3CHO was continuously increased with increasing negative potential from −0.55 to −1.2 V, while that of CO followed the reverse trend. In the presence of Zr4+ a relatively high \%CE of CH3CHO (17.6\%) was obtained. The main conclusion of this work is that the rate of CO2 reduction can be increased at low overpotentials and the distribution of the products can be controlled simply by varying the composition of the electrolyte.}, | |

| abstract = {Abstract | |
| Ceria offers great promise in catalysis, due to its facile switchable oxidation state manifested from its oxygen buffering capability. This work presents the first equilibrium surface phase diagram of ceria exposed to various oxygen providing reservoirs (e.g., a pure O2 reservoir as well as NO/NO2, H2/H2O, or CO/CO2 redox environments) using first principles thermodynamics. For a pure O2 environment, the stoichiometric ceria (111) surface is favored at ambient conditions. Any appreciable surface reduction is observed only at ultra-low oxygen partial pressures (\< 10− 30 atm) and room temperature or at temperatures \> 2000 K and ambient pressures. On the other hand, a redox environment promotes surface reduction at temperatures as low as 300 K. Semi-local, Hubbard modified semi-local, and hybrid electronic exchange-correlation functionals are used to capture the energetics and phase transitions. We observe no difference between the three theories in the energetics governing ceria surface reduction in the dilute limit. The predicted phase transitions by all levels of theory are in agreement with each other and in excellent agreement with literature experimental data. Creation of oxygen vacancies in the sub-surface is energetically favored over surface vacancies, and is pivotal in determining the key features of the surface phase diagram. Consequently, we identify the oxygen vacancy formation energy as a descriptor for the surface reactivity of ceria in various oxygen environments. This single governing factor could be used in future studies to probe the surface reactivity of ceria and also to design improved ceria-based materials for redox reactions.}, | |

| abstract = {We present the case for the nonempirical construction of density functional approximations for the exchange-correlation energy by the traditional method of “constraint satisfaction” without fitting to data sets, and present evidence that this approach has been successful on the first three rungs of “Jacob’s ladder” of density functional approximations [local spin-density approximation (LSD), generalized gradient approximation (GGA), and meta-GGA]. We expect that this approach will also prove successful on the fourth and fifth rungs (hyper-GGA or hybrid and generalized random-phase approximation). In particular, we argue for the theoretical and practical importance of recovering the correct uniform density limit, which many semiempirical functionals fail to do. Among the beyond-LSD functionals now available to users, we recommend the nonempirical Perdew–Burke–Ernzerhof (PBE) GGA and the nonempirical Tao–Perdew–Staroverov–Scuseria (TPSS) meta-GGA, and their one-parameter hybrids with exact exchange. TPSS improvement over PBE is dramatic for atomization energies of molecules and surface energies of solids, and small or moderate for other properties. TPSS is now or soon will be available in standard codes such as GAUSSIAN, TURBOMOLE, NWCHEM, ADF, WIEN, VASP, etc. We also discuss old and new ideas to eliminate the self-interaction error that plagues the functionals on the first three rungs of the ladder, bring up other related issues, and close with a list of “do’s and don’t’s” for software developers and users.}, | |

| abstract = {The adsorption energy of reactant molecules and reaction intermediates is one of the key descriptors of catalytic activity of surfaces and is commonly used as a metric in screening materials for design of heterogeneous catalysts. The efficacy of such screening schemes depends on the accuracy of calculated adsorption energies under reaction conditions. These adsorption energies can depend strongly on interactions between adsorbed molecules in the adlayer. However, these interactions are typically not accounted for in screening procedures that use DFT-based zero-coverage adsorption energies. Identifying the physical mechanisms behind these interactions is essential to model realistic catalyst surfaces under reaction conditions and to understand the dependence of adsorption energies on reaction parameters like surface strain and composition. This article describes a method to quantitatively resolve the observed inter-adsorbate interactions into various direct adsorbate–adsorbate interactions (i.e. Coulombic and steric) and surface-mediated interactions (i.e. adsorbate-induced surface relaxation and change in electronic structure) by combining density functional theory and cluster-expansion calculations of coverage-dependent adsorption energies. The approach is implemented on a model catalyst surface of FeS2(100) reacting with H2S molecules. We find that the adsorption energy of H2S molecules can be affected by over 0.55 eV by the repulsive inter-adsorbate interactions caused primarily by the adsorbate-induced changes to the electronic structure of the FeS2 surface. These interactions also show a strong monotonic dependence on surface strain, being three times stronger on compressively strained surfaces than on surfaces under tensile strain. The large magnitude of inter-adsorbate interactions as well as their strong dependence on lattice strain demonstrate the need for using coverage-dependent adsorption energies for more accurate screening, for example for strained catalytic systems like core–shell and overlayer structures.}, | |

Here, we review the first steps towards using computational methods to design new catalysts. Examples include screening for catalysts with increased activity and catalysts with improved selectivity.

| abstract = {This paper deals with the ground state of an interacting electron gas in an external potential v(r). It is proved that there exists a universal functional of the density, F[n(r)], independent of v(r), such that the expression E≡∫v(r)n(r)dr+F[n(r)] has as its minimum value the correct ground-state energy associated with v(r). The functional F[n(r)] is then discussed for two situations: (1) n(r)=n0+ñ(r), ñn0≪1, and (2) n(r)=ϕ(rr0) with ϕ arbitrary and r0→∞. In both cases F can be expressed entirely in terms of the correlation energy and linear and higher order electronic polarizabilities of a uniform electron gas. This approach also sheds some light on generalized Thomas-Fermi methods and their limitations. Some new extensions of these methods are presented.}, | |

The model incorporates nucleation of oxide islands via conversion of on-surface to back-bonded oxygen, together with an observed transformation in the shapes of just-formed islands from linear to two-dimensional. Model analysis via Kinetic Monte Carlo simulation quantifies oxygen uptake and oxide island nucleation kinetics, including possible enhanced nucleation at step edges. Simulated etching of vicinal Si(100) surfaces reveals that receding steps are pinned by oxide islands and transform into finger-like structures even at higher temperatures where oxide island growth is inhibited.}, | |

| abstract = {High resolution electron energy loss spectroscopy (HREELS), low-energy electron diffraction(LEED), and thermal desorptionspectroscopy (TDS) were used to study lateral interactions in the adsorbate layer of the CO/Rh(111) system. The vibrational spectra show that CO adsorbs exclusively on top at low coverage. At about half a monolayer a second adsorption site, the threefold hollow site, becomes occupied as well. A steady shift to higher frequencies of the internal C–O vibrations is observed over the whole coverage range. The frequency of the metal CO (M–CO) vibration in the on-top mode hardly shifts at low coverage. However, upon the emergence of the second adsorption site the M–CO vibrations experience a shift to lower frequencies. The population of the second site is also accompanied by the development of a low temperature shoulder in the TD spectra, indicating an increasingly repulsive interaction in the adsorbed CO layer. Vibrational spectra of isotopic mixtures of 12 CO and 13 CO were used to assess the origin of the observed frequency shifts. They confirm that frequency shifts of the C–O stretching vibration at total CO coverage of 0.33 ML in the (√3×√3) R 30° structure arise purely from dipole–dipole coupling. Dilution of an isotopic species effectively suppresses frequency shifts arising from dipole–dipole coupling. Therefore, experiments with a small amount of 13 CO as a tracer to monitor the frequency shifts in the 12 CO adlayer were carried out over the entire coverage range of 12 CO . The results demonstrate that dipole–dipole coupling causes the frequency shifts at low coverage (\<0.5 ML), whereas chemical effects set in at higher coverage (0.5–0.75 ML), connected with the population of the threefold sites. The results illustrate that HREELS in combination with isotopic dilution is a powerful tool in the assessment of lateral interactions between adsorbed molecules.}, | |

| abstract = {The introduction of in situ techniques has had a vast impact on research and development in the area of heterogeneous catalysis as emphasized in many reviews and monographs. Recently, the number of in situ techniques that can give information at the atomic scale has increased significantly and new possibilities exist for making the measurements under industrially relevant conditions. In order to fully exploit the results from the in situ and operando studies, it has also become increasingly gainful to combine the experimental studies with theoretical methodologies based on, for example, Density Functional Theory (DFT). This has allowed one to extract more detailed atomic-scale information from the measurements and it has also allowed the establishment of detailed structure-activity relationships. Furthermore, the interplay between in situ techniques and theory has helped bridging the pressure gap such that in situ information obtained at conditions far from industrial ones may be used in a more relevant manner. Here, we will illustrate how microscopy-, spectroscopy- and X-ray-based techniques in combination with experimental and theoretical surface science methods can aid industrial catalyst developments. We will do this by presenting examples of our current understanding and latest developments in the areas of heterogeneous nano-particle catalysts for methanol synthesis, steam reforming and hydrotreating.}, | |

| abstract = {We employ a first-principles lattice-gas Hamiltonian (LGH) approach to determine the lateral interactions between O atoms adsorbed on the Pd(100) surface. With these interactions, we obtain an ordering behavior at low coverage that is in quantitative agreement with experimental data. Uncertainties in the approach arise from the finite LGH expansion and from the approximate exchange-correlation (xc) functional underlying the employed density-functional theory energetics. We carefully scrutinize these uncertainties and conclude that they primarily affect the on-site energy, which rationalizes the agreement with the experimental critical temperatures for the order-disorder transition. We also investigate the validity of the frequently applied assumption that the ordering energies can be represented by a sum of pair terms. Restricting our LGH expansion to just pairwise lateral interactions, we find that this results in effective interactions which contain spurious contributions that are of equal size, if not larger than any of the uncertainties, e.g., due to the approximate xc functional.}, | |

For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary controlled for Pd(100) in the temperature range investigated, from 30 °C to 120 °C. On Pd75Ag25(100) the surface oxide reduction is significantly slower compared to Pd(100). Also in this case, a phase boundary controlled reduction of the surface oxide is observed at temperatures of 120 °C and above, while at T ≤ 70 °C the reduction is found to be diffusion limited. Density functional theory calculations show that the presence of silver in the outermost surface layer significantly increases the CO diffusion barriers on the reduced areas, supporting a diffusion limited reduction process for Pd75Ag25(100) at lower temperatures.}, | |

The industrial application of propane ODH has not succeeded so far due to low propene yields. Therefore, propane ODH has been extensively investigated in recent decades using different catalysts and reaction conditions. Although several important aspects have been discussed in previous reviews (e.g., supported vanadium oxide catalysts, bulk catalysts, productivity toward propene, etc.), other relevant aspects have not been addressed (e.g., support effects, loading effects, vanadia precursor or catalyst synthesis methods, surface impurities, structure?reactivity relationships, etc.). In this review, we endeavor to cover the majority of the publications with an emphasis on the following: (1) catalyst synthesis: to focus on the influence of synthesis methods on the final vanadium oxide surface species, (2) catalyst characterization: to identify the molecular structures of the supported vanadium oxide species as well as the oxide support surface physical and chemical characteristics, (3) kinetics: to understand how reaction rates depend on variables such as concentration of gas-phase reactants and temperature, (4) structure?activity relationship: to examine the influence of the concentration as well as molecular structures of the surface vanadium oxide species on the reaction kinetics, and (5) reaction mechanism: to use the structure?activity relationships as well as kinetic studies plus theoretical calculations to corroborate and/or propose reaction pathways that account for the overall ODP reaction mechanism.}, | |

The transformation from fcc to bcc starting from a flat interface with the fcc(1 1 1)//bcc(1 1 0) and fcc[1 1 ]//bcc[0 0 ] orientation in a single component system has been simulated. Growth occurs in two different modes depending on the chosen values of the bond energies. For larger fcc-bcc energy differences, continuous growth is observed with a rough transformation front. For smaller energy differences, plane-by-plane growth is observed. In this growth mode two-dimensional nucleation is required in the next fcc plane after completion of the transformation of the previous fcc plane.}, | |

| abstract = {As a first step towards gaining microscopic understanding of copper-based catalysts, e.g., for the low-temperature water-gas shift reaction and methanol oxidation reactions, we present density-functional theory calculations investigating the chemisorption of oxygen, and the stability of surface oxides on Cu(111). We report atomic geometries, binding energies, and electronic properties for a wide range of oxygen coverages, in addition to the properties of bulk copper oxide. Through calculation of the Gibbs free energy, taking into account the temperature and pressure via the oxygen chemical potential, we obtain the (p,T) phase diagram of O∕Cu(111). Our results show that for the conditions typical of technical catalysis the bulk oxide is thermodynamically most stable. If, however, formation of this fully oxidized surface is prevented due to a kinetic hindering, a thin surface-oxide structure is found to be energetically preferred compared to chemisorbed oxygen on the surface, even at very low coverage. Similarly to the late 4d transition metals (Ru, Rh, Pd, Ag), sub-surface oxygen is found to be energetically unfavorable.}, | |

| abstract = {Atoms and molecules adsorbed on metals affect each other indirectly even over considerable distances. Via systematic density-functional calculations, we establish the nature and strength of such interactions, and explain for what adsorbate systems they critically affect important materials properties. This is verified in kinetic Monte Carlo simulations of epitaxial growth, which help rationalize a number of recent experimental reports on anomalously low diffusion prefactors.}, | |
