University of Massachusetts Amherst (UMass) scientists have developed a more efficient, easily processed and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the “electrode barrier.” Polymer scientists and synthetic chemists have been working for decades to improve the power conversion efficiency of organic solar cells. The effort has been [...]

A team of researchers at the University of Texas at Arlington has discovered a way to cool electrons to -228 °C without external means and at room temperature. This can be an impressive advancement that may enable electronic devices to function with very little energy. In the image above is a chip that contains nanoscale [...]

Lawrence Berkeley National Laboratory has released information about a new concept in metallic alloy design called “high-entropy alloys”. The multi-element high-entropy alloy not only tests out as one of the toughest materials on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures. [...]

Brown University scientists have discovered that copper foam could provide a new way of converting excess carbon dioxide into useful industrial chemicals. The catalytic foam is foamy form of copper with vastly different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide. The work done at Brown University’s Center for the [...]

A hybrid form of perovskite, the same type of material that has recently been found to make highly efficient solar cells that could one day replace silicon, has been used to make low-cost, easily manufactured LEDs. This particular class of semiconductor perovskites has generated excitement in the solar cell field over the past several years, [...]
