Journal ArticleDOI
Effect of Alloying on the Optical Properties of Ag–Au Nanoparticles
TL;DR: In this article, the optical response of Au-Ag bimetallic nanoalloys has been studied using pseudopotential time-dependent density-functional theory calculations, in qualitative agreement with available experiment and previous calculations.
Journal ArticleDOI
Aspect-ratio- and size-dependent emergence of the surface-plasmon resonance in gold nanorods – an ab initio TDDFT study
TL;DR: It is demonstrated that small Au nanorods with a high aspect ratio develop a strong longitudinal SPR, with intensity comparable to that in Ag rods, as soon as the resonance energy drops below the onset of the interband transitions due to the geometry.
Journal ArticleDOI
New opportunities to understand heterogeneous catalysis processes on nanoscale bimetallic particles through synchrotron radiation and theoretical studies
TL;DR: In this paper, the relaxation of the intermetallic distances and the chemical local ordering can be predicted from the electronic structure of a bimetallic system at thermodynamical equilibrium.
Journal ArticleDOI
Ordering and surface segregation in Co 1 -c Pt c nanoparticles: A theoretical study from surface alloys to nanoalloys
TL;DR: In this paper, Monte Carlo simulations within a tight-binding Ising model (TBIM) were performed on bulk, surfaces, and nanoclusters of Co-Pt alloys in order to describe and understand the competition or synergy between surface segregation and chemical ordering phenomena in nanoalloys.
Journal ArticleDOI
CO Adsorption-Induced Surface Segregation and Formation of Pd Chains on AuPd(100) Alloy: Density Functional Theory Based Ising Model and Monte Carlo Simulations
TL;DR: In this article, an Ising model based on density functional theory calculations is derived to define interatomic potentials that describe metal-metal, metal-CO, and CO-CO interactions.
