(Phys.org)—A team of researchers at Nanjing University in China has developed a new kind of solar desalinating device that does not require a traditional solar concentrator or thermal insulation. Instead, as the group explains ...
Some materials can generate a small voltage when bent and, conversely, can bend in response to a voltage. This phenomenon is called flexoelectricity, and until now, it was thought that the effect only existed in electrical ...
