Perovskites under pressure: Hot electrons cool faster

In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...

Putting on the pressure improves glass for fiber optics

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these ...

Supercritical answer to waste oil found

Lubricating oils deteriorate and oxidize with use as well as accumulating particles from the engines and other machinery in which they are used. Ultimately, their effectiveness worsens and they begin to damage the components ...
