Enhancement of the ozone-sensing properties of ZnO through chemical-etched surface texturing Abstract: Semiconductor metal oxides (SMOx) are widely studied for different applications. It is well established that the gas-SMOx interaction strongly depends on the charge […]
Light-assisted ozone gas-sensing performance of SnO2 nanoparticles: Experimental and theoretical insights Abstract: We report herein an investigation on the ozone gas-sensing performance at room temperature of SnO2 nanoparticles assisted by a light-emitting diode. X-ray diffraction and […]
Ozone detection in the ppt-level with rGO-ZnO based sensor Abstract: Although several studies have explored the rGO-ZnO nanocomposites gas sensing properties towards many gases, only a few are devoted to ozone detection. This paper explores […]
Unveiling the efficiency of microwave-assisted hydrothermal treatment for the preparation of SrTiO3 mesocrystals Abstract: Material processing has become essential for the proper control, tuning and consequent application of the properties of micro/nanoparticles. In this case, […]
Highly selective ozone gas sensor based on nanocrystalline Zn0.95Co0.05O thin film obtained via spray pyrolysis technique Abstract: Chemiresistors are highly important for monitoring and detection of harmful gases produced from industrial processes and vehicle emissions. We […]
Improving the ozone gas-sensing properties of CuWO4 nanoparticles Abstract: This paper consists of an experimental investigation on the effects of annealing temperature on the structural, surface and ozone gas-sensing properties of CuWO4 nanoparticles prepared via a […]
