In this manuscript, we prepared gold nanorods (Au-NRs) through “silver-assisted seeded methodology” and studied their outermost layer using XPS spectroscopy and ab initio calculations to compare the chemical states of the constituents of the meta

Density Functional Theory based on ab initio calculations was employed to investigate single and complex defects of oxygen in indium nitride and their influence on the optical properties. Different oxygen contents (x=1.38%, 4.16%, 5.55% and 11.11%) w

A garnet (G7) silicate mineral belonging to pyralspite subgroup was studied using the technique of electron spin resonance (ESR). This study shows that iron is present in G7 as isolated species as well as species coupled by dipolar interactions. The
