Researchers have come much closer to their goal of converting waste heat into electrical power at small temperature differences. They managed to increase electrical power per footprint of thermomagnetic generators based on Heusler alloy films by a factor of 3.4.
The sensitivity of the device is already superior to commercially available analogs based on semiconductors and superconductors, which opens up prospects for applications of the graphene detector in wireless communications, security systems, radio astronomy, and medical diagnostics.
A surprisingly simple method improves 'drop casting' fabrication of tiled nanosheets that could be used in next-generation electronic devices. All you need is a pipette and a hotplate.
