(Phys.org)—Photographic film maker Fujifilm has been busy this year at the Nanotech 2013 conference being held in Tokyo. First came news of bendable/roll up speakers. Now the company is showing off a new thermoelectric ...
Thermoelectric devices—which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts—have been explored in the laboratory since the ...
