The effect of acids precipitants on the synthesis of WO3 hierarchical nanostructures for highly selective and sensitive H2S detection

Frontiers in Sensors, 2023
The detection and monitoring of H2S gas at high and lower concentrations is very crucial since this gas is highly toxic and can affect tissues and organs, especially in occupational environment.

Electrical and mechanical studies on ferroelectric lithium rubidium sulphate crystals [PDF]

Journal of Advanced Dielectrics, 2018
Slow evaporation method was used to grow single crystals of lithium rubidium sulphate with high transparency. Single crystal X-ray diffraction analysis shows that at room temperature, the crystal belongs to a monoclinic system with the space group P21/n.

High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system [PDF]

, 2012
In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedicated to the classical piezoelectric, lead-zirconate-titanate (PZT) ceramic ...

Correlating the Energetics and Atomic Motions of the Metal-Insulator Transition of M1 Vanadium Dioxide [PDF]

, 2016
Materials that undergo reversible metal-insulator transitions are obvious candidates for new generations of devices. For such potential to be realised, the underlying microscopic mechanisms of such transitions must be fully determined.
