Nearly all animals are capable of sensing changes in environmental oxygen (O2) and carbon dioxide (CO2) levels, which can signal the presence of food, pathogens, conspecifics, predators, or hosts. The free-living nematode Caenorhabditis elegans is a powerful model system for the study of gas sensing. C.

Gas-sensing selectivity of n-ZnO/p-Co3O4 sensors for homogeneous reducing gas
, 2021Poor selectivity has always been the most severe challenge in the practical applications of gas sensors based on metal-oxide semiconductors (MOSs). It is difficult to distinguish CO and H2 because of the cross-sensitivity phenomenon.

Sensors and Actuators B: Chemical, 1994
Abstract Solid-electrolyte sensors for detecting air pollutants are urgently needed for the sake of environmental protection. Rapid progress is being marked in the development of sensors for CO 2 , NO 2 , NO, SO 2 , ozone and fluorocarbons. Some of them, such as the CO 2 sensor, have almost reached a stage of practical application, while others are ...
