Physical and chemical properties of solid materials are strongly. influenced by the chemical
composition of internal interfaces, One of the crucial parameters affecting interfacial …

Some aspects of particle size, bimetallic formulation and metal–support interaction on the
catalytic properties of supported metal catalysts in the hydrogenolysis of C–C and C …

Grain boundaries are important structural components of polycrystalline materials used in
the vast majority of technical applications. Because grain boundaries form a continuous …

The surface composition of Ni-Cu alloys has been calculated as a function of atomic layer,
crystal face, and bulk composition at a temperature of 800 K. The results show that the …

An overview about the effect of co-metal on the performance of Pd in bimetallic catalysts is
presented. In the first part, the promotion of monometallic catalysts by addition of a second …

Previous models of surface segregation have generally been based on the assumption that
a decrease in surface free energy constitutes the predominant driving force for the …

A set of embedded-atom method (EAM) potentials for Al Mg alloys are developed using the
“force matching” method. The potentials are fitted to both experimental data and a massive …

Publisher Summary This chapter discusses the catalysis by alloys in hydrocarbon reactions.
With solution alloys the effect of alloying on the electronic structure is surprisingly small, and …

The available models for grain-boundary diffusion are reviewed together with the relevant
mathematical techniques for extracting the grain-boundary diffusivity from the various types …

In this work, we aim to update the understanding of how impurity or promoter metals
segregate on metal surfaces, particularly in the application of single-atom alloys (SAA) for …
