Herein we synthesized bi-metallic Pd@Ni and Au@Ni core-shell-like nanoparticles (NPs) for glycerol electrooxidation reaction (GEOR) in alkaline media. The morphological, structural and surface properties of the NPs were evaluated using a range of phy

NiTi alloy has important properties such as shape-memory, super-plasticity, resistance, and biocompatibility, therefore is frequently used in biomedical devices. We studied the oxidized form of this alloy and possible Ni segregation in three possible

We performed density functional calculation of the acetylene hydrogenation reaction on the PdGa(110) surface. The reaction C 2 H 2 +H 2 → C 2 H 4 is modeled and understood in terms of chemical bonding change. The evolution of electronic structure a

First-principles calculations based on the density functional theory (DFT) were applied to study the H2 adsorption on Au@Pd NP (core@shell icosahedral bimetallic nanoparticle). The calculations indicate that, for almost all adsorption sites, there is

In this work we performed density functional theory (DFT) calculations, analyzing the effects of adsorption of several alkali metals (AM) on pristine and defective (8,0) single-wall carbon nanotube (SWCNT). We found that after AM adsorption the semic

The Spin-polarized density functional theory is used to study the effect of a single vacancy in a (8,0) single-walled carbon nanotube (SWCNT) on the Rh clustering process. The vacancy is considered oxygenated and non-oxygenated and, in each case, dif
