## Abstract We introduce a simple method to fabricate an ammonia gas sensor with a nanocomposite of singleβwalled carbon nanotubes (SWNTs) and SnO~2~. The nanocomposite showed a semiconducting property. With exposure to ammonia gas, the electrical resistance of the nanocomposite sensor increases ra
A new rapid detecting method (called dynamic measurements) was reported to detect and distinguish the presence of two pesticide gases in the ambient atmosphere. The method employed only a single SnO 2 -based gas sensor in a rectangular temperature mode to perform the qualitative analysis of a binary
