Soft ferrites are very important electronic materials because of their electrical and magnetic behavior. In last decade, remarkable efforts have been taken for the development of ferrite gas sensors in detection of toxic gas pollutants from vehicle exhaust, biological hazards, environment, and pollution monitoring.

Abstract A general purpose instrument embodying the principles of an electronic nose suggests a very extensive system of sensors, software and output indicators, with obvious disadvantages in terms of cost and, hence, commercial viability. However, many of these disadvantages can be overcome if a modular approach to system design is adopted.

Abstract Measurements with dilute gaseous mixtures of hydrocarbons and oxygen in a nitrogen carrier gas have shown that the workfunction of a Pt film in interaction with the gas phase changes abruptly and reversibly by approximately 0.7 eV at elevated temperature as the concentrations of the chemically active species are varied through their ...
