Contact electrification can arise when physical contact occurs between two materials. In a new report now published on Science Advances, Ding Li, and a team of scientists in nanoscience, nanoenergy and materials science in ...
When a piece of conducting material is heated up at one of its ends, a voltage difference can build up across the sample, which in turn can be converted into a current. This is the so-called Seebeck effect, the cornerstone ...
