Metal, metal oxide, and metal chalcogenide materials have a wide variety of applications.
For example, many metal clusters and nanoparticles are used as catalysts for reactions …

Gold is an element whose unique properties are strongly influenced by relativistic effects. A
large body of appropriate calculations now exists and its main conclusions are summarized …

Subnanometric transition-metal (TM) clusters have attracted great attention due to their
unexpected physical and chemical properties, leastwise compared to their bulk …

Graphene nanosheets serve as excellent support materials in the synthesis of advanced
metal nanoparticle–graphene electrocatalysts. In this study, we employ a combination of …

The knowledge of the atomic structure of clusters composed by few atoms is a basic
prerequisite to obtain insights into the mechanisms that determine their chemical and …

We study optical bistability (OB) behavior based on intersubband transitions in asymmetric
double quantum wells (QWs) where tunneling-induced quantum inference can be observed …

We analyze hybrid absorptive-dispersive optical bistability (OB) and multistability (OM)
behavior in a generic N-type atomic system driven by a degenerate probe field and a …

Ab initio calculations on Pt clusters having diameters of up to about 3 nm show planar,
layered, pyramidal, cage, simple cubic, and octahedral growth. Planar structures are …

The lowest-energy structure of thiolate-group-protected Au38 (SR) 24 is with ab initio
computations. A unique bi-isocahedral Au23 core is predicted for the Au38 (SR) 24 cluster …

Density functional theory (DFT) calculations were carried out to study gold clusters of up to
55 atoms. Between the linear and zigzag monoatomic Au nanowires, the zigzag nanowires …
