With the escalating global awareness of air quality management, need for continuous and reliable monitoring toxic gases by using low-power operating systems has become increasingly important. One which, semiconductor metal oxide gas sensors have received great attention due to their high/fast response simple working mechanism. More specifically, self-heating sensors, wherein direct thermal activation in sensing material, been sought low power-consuming characteristics. However, previous...
The high explosiveness of hydrogen gas in the air necessitates prompt detection settings where is used. For this reason, sensors are required to offer rapid and possess superior sensing characteristics terms measurement range, linearity, selectivity, lifetime, environment insensitivity according publicized protocol. However, previous approaches have only partially achieved standardized requirements been limited their capability develop reliable materials for spatially accessible systems....
A plan-view analytical method to detect nano-voids of deposited copper layers, especially for the fabrication printed circuit boards, was investigated using transmission electron microscopy (TEM). Through electroless plating, thin layers were directly on small silicon nitride window grids, and presence within confirmed with various TEM techniques. The amount size further quantified from images, making it possible compare quickly multiple samples prepared under plating conditions. This is...
