We present results on the formation of thin films of the charge transfer salts tetrathiafulvalene (TTF) and tetracyanoquinodimethane (TCNQ) prepared by physical vapor deposition on several substrates in a high vacuum. We mainly investigate the influe

Distributed power-supply systems have become more widespread recently. Recent distributed systems, such as fuel cells, offer high energy-use efficiency because they generate heat or hot water and electric power simultaneously. However, to avoid globa

We developed a sensor element for detecting formaldehyde. The sensor element was made of a porous glass impregnated with both a Schiff's reagent and an acid. The sensor element changed its color from yellow to violet after exposure to formaldehyde, a
