The DSC method has been employed to monitor the kinetics of reticulation ofaqueous polyurethane systems without catalysts, and with the commercial catalyst of zirconium(CAT^®XC-6212) and the highly selective manganese catalyst, the complex Mn(III)-dia...

The precursors of SnO₂ or In₂O₃/SnO₂ nanocrystlline powders have been prepared bythe sol-precipitation method. The precursors were calcined at different temperatures to prepareSnO₂ or In₂O₃/SnO₂ nanocrystalline powders with different particle sizes....

Effects of surface chemical modification with sodium silicate on the gas-sensingproperties of F-doped SnO₂ gas sensor designed and fabricated employing micro-electromechanical system (MEMS) technology were investigated. Gas sensing properties of thes...

Light-dependent resistances (LDR) are cheap light sensors. A less known lightdetector is the electret microphone, whose electret membrane functions as a perfectabsorber, but only detects pulsed light. The aim of this study was to analyze the use of a...

In case of typical chemical gas sensors reacted by gas adsorption on surface of anactive layer, it is difficult to detect some gases which have low chemical adsorption energylike inert gases. In this paper, we report a gas sensor using carbon nanotub...

The ionophore 1,4,7,10,13-penta(n-octyl)-1,4,7,10,13-pentaazacyclopentadecane(L¹) was used for the development of miniaturised perchlorate-selective electrodes in thick-film technology. Different PVC membranes containing L¹ and the plasticizers o-nit...

In this paper, a novel nano aqueous flow sensor which consists of two closelyspaced amperometric sensors is investigated by digital simulation. The simulation resultsindicate that the ratio of the responses of two closely spaced amperometric sensors...
