Electronic noses (E-noses) use various types of electronic gas sensors that have partial
specificity. This review focuses on commercial and experimental E-noses that use metal …

Desired properties of a chemical sensor include high sensitivity, a large dynamic range, high
selectivity or specificity to a target analyte, related low cross-sensitivity to interferents, perfect …

Abstract Samarium oxide (Sm 2 O 3) nanorods were prepared by a facile hydrothermal route
using cetyl trimethyl ammonium bromide (CTAB) as an organic surfactant. The structural and …

Sensitive and selective detection of acetone in human exhaled breath plays an important
role in the diagnosis of diabetes. However, obtaining a reliable response to ppb levels of …

Engineering approaches designed to improve the parameters of conductometric gas
sensors, are considered in this short survey. In particular, in the first part of the paper we …

Nanostructured materials have attracted considerable research interest over the recent
decades because of their potential applications in nanoengineering and nanotechnology …

Nanocrystalline SnO2, In2O3 and In2O3–SnO2 thin films have been prepared by modified
sol–gel methods making use of no-standard precursors and a suitable surfactant. The oxide …

The gas sensing behavior of a single SnO2 gas sensor was investigated based on a
dynamic measurement method in which temperature was modulated by heating waveform …

Sharp operating temperature fluctuations in an analyte-exposed gas sensor result in
temporal responses containing considerable amounts of extractable analyte-related …

Magnesium doped SnO 2 polycrystalline thin films are deposited by Spray pyrolysis by
adding small amount of Mg between 0.3 and 1.2 wt%. Mg do** significantly modifies the …
