Due to the dramatic growth in industrial development and population, the natural atmospheric environment has become polluted and is rapidly deteriorating. Thus, the monitoring and control of such pollutants is imperative to prevent environmental disasters. Conventional analytic instruments for this purpose are time consuming, expensive, and seldom used

Ultraselective Toluene-Gas Sensor: Nanosized Gold Loaded on Zinc Oxide Nanoparticles.
Analytical Chemistry, 2018Selectivity is an important parameter of resistive-type gas sensors that use metal oxides. In this study, a highly selective toluene sensor is prepared using highly dispersed gold-nanoparticle-loaded zinc oxide nanoparticles (Au-ZnO NPs).

Abstract The various ways that gaseous species can affect the resistance of a semiconductor are discussed, with particular emphasis on those where the effect is reversible and, hence, suitable for gas sensing. These latter include reduction/oxidation of the semiconductor, anion exchange with the semiconductor, adsorption directly on the semiconductor

Abstract This paper proposes a new sensing principle for gas detection. The working principle is based on the ultrasonic resonance within a cavity. Such sensors are working in flow-through conditions at, or near, room temperature. A quartz crystal resonator generates ultrasonic waves within a cavity. These are reflected by the cavity wall. If the gap
