Germanium Semiconductor Made Superconductor by Gallium Doping
Over on ScienceDaily we learn that an international team of scientists have turned a common semiconductor germanium into a superconductor. Researchers have been able to make the semiconductor germanium superconductive for the first time by incorporating gallium into its crystal lattice through the process of molecular-beam epitaxy (MBE). MBE is the same process which is […]

A Solderless, Soluble Circuit Board
Anyone who’s spent significant amounts of time salvaging old electronics has probably wished there were a way to take apart a circuit board without desoldering it. [Zeyu Yan] et al seem to have had the same thought, and so designed circuit boards that can be dissolved and recycled when they become obsolete. The researchers printed […]

Reducing Carbon Emissions With Coal
It might seem like a paradox, but coal might hold the answer to solving carbon emission problems. The key isn’t burning it, but creating it using carbon dioxide from the atmosphere.  While this has always been possible in theory, high temperatures make it difficult in practice. However, a recent paper in Nature Communications shows how […]
