A classification and ranking system on the H2 gas sensing capabilities of nanomaterials based on proposed coefficients of sensor performance and sensor efficiency equations

Author: Mwakikunga, Bonex W ; Motshekga, S ; Sikhwivhilu, L ; Moodley, M ; Scriba, Manfred R ; Malgas, G ; Simo, A ; Maaza, M ; Ray, Suprakas S Date: Jul 2013 A coefficient of performance is defined based on the traditional definitions of response, S, of a chemoresistive sensing material to a specific gas from resistance–time data. The new definition not only considers the S(sub response) and S(sub ... Read more
VO2 nanostructures based chemiresistors for low power energy consumption hydrogen sensing

Author: Simo, A ; Mwakikunga, Bonex W ; Sone, BT ; Julies, B ; Madjoe, R ; Maaza, M Date: May 2014 Mott-type VO(sub2) oxide nanobelts are demonstrated to be effective hydrogen gas sensors at room temperature. These nanobelts, synthesized by hydrothermal process and exhibiting the VO(sub2) (A) crystallographic phase, display room temperature ... Read more
