Metal oxide nanomaterials have been widely utilized in gas sensors due to their excellent performance. Comparing to n-type metal oxides, p-type ones have been less studied for gas sensing applications. In this work, CuO nanoplates were synthesized at different temperatures by a facile hydrothermal r[r]

The solvent-free microwave heating protocol offers significant rate enhancement compared to conventional synthesis done through oil bath heating. In general, the time taken for MTNPc synthesis was shortened from 4-5 hours to 3-6 minutes. The drastic reduction in reac[r]

The coefficients of thermal expansion of thin metal film with face-centered cubic structure at zero pressure are investigated using the statistical moment method (SMM), including the anharmonic effects of thermal lattice vibration.
