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 […]

Chalmers University of Technology researchers recently unveiled a promising breakthrough for the lithium sulfur battery, using a catholyte with the help of a graphene sponge. Lithium sulfur batteries, which offer a theoretical energy density more than five times that of lithium ion batteries could meet the demands of an electric future when new battery technologies […]

Rensselaer Polytechnic Institute researchers have created a lithium-ion battery that can charge in a matter of minutes but still operate at a high capacity as is possible. The development has the potential to improve battery performance for consumer electronics, solar grid storage, and electric vehicles. The paper explaining the results as been published in Nature […]
