As a special class of materials, transition metal oxides exhibit in their crystalline phase a variety of interesting properties, such as metal-insulator transition, ferroelectricity, magnetism, superconductivity, and so ...

The presented work shows a synthesis route to obtain nanoparticles of the hexagonal α-NiS phase and core-shell particles where the same material is grown onto previously prepared Au seeds. In the bulk, this nickel sulfide ...
