This review focuses on the synthesis of p-type metal-oxide (p-type MOX) semiconductor thin
films, such as CuO, NiO, Co3O4, and Cr2O3, used for chemical-sensing applications. P-type …

Hydrogen (H2) has been considered as one of the cleanest renewable energy sources.
However, it is still challenging to use H2 due to its hazardous flammable and explosive …

This paper discusses the direct fabrication of ultrathin Ni (OH) 2 nanosheets on substrates
via a facile solvothermal process, which is free from the use of additional surfactants. The …

Metal oxide heterostructures have great potential in gas sensor devices due to the attractive
chemical and electronic properties at the heterogeneous interfaces. Herein, a unique …

The cumulative aquatic contamination and contagious diseases in the present modernity are
