Collaborators of three labs in Mexico have demonstrated an innovative nanodevice for harvesting solar energy. The study paper has been published in the SPIE Journal of Nanophotonics. The paper, “Thermoelectric efficiency optimization of nanoantennas for solar energy harvesting,” reports that evolutive dipole nanoantennas (EDN) generate a thermoelectric voltage three times larger than the classic dipole […]

University of Texas at Austin’s Texas Advanced Computing Center has shown that a voltage can be generated by harnessing differences in spin populations on a metal contact attached to a ferromagnetic material through a mechanism known as the Spin Hall effect. The researchers used supercomputers to identify various forms of cobalt oxide combined with nickel […]

University of Zurich physicists have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it will gradually […]

An international team of scientists looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind […]

University of Houston researchers, taking advantage of recent advances in using theoretical calculations to predict the properties of new materials, have discovered a new class of half-Heusler thermoelectric compounds, including one with a record high figure of merit – a metric used to determine how efficiently a thermoelectric material can convert heat to electricity. Physicist […]
