A new technique developed by researchers at Aalto University and Oak Ridge National Laboratories in the US can detect Cooper pairs occurrence with atomic precision. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in […]

Researchers at ETH Zurich have investigated how fast electrons can ultimately be controlled with electric fields. The ETH team’s work is important for the petahertz electronic speed ranges of the future. Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Speed is the basis for technologies […]

Scientists researching superconductors at the U.S. Department of Energy’s Argonne National Laboratory (ANL) have discovered a previously unknown phase in a class of superconductors called iron arsenides. The discovery offers new information on a debate over the interactions between atoms and electrons that are responsible for their unusual superconductivity. Ray Osborn, an Argonne physicist and […]

Researchers at the Institute of Photonic Science (ICFO), in collaboration with Massachusetts Institute of Technology, USA, Max Planck Institute for Polymer Research, Germany, and Graphenea S.L. Donostia-San Sebastian, Spain have demonstrated graphene is able to convert a single photon such that when it’s absorbed it releases multiple freed electrons. This is a very promising discovery.  […]

The estimable Al Fin found a great explanation of grid operations with a truly useful analogy for imagining what goes on.  The explanation was written by Howard Shaffer, a Licensed Professional Nuclear Engineer in a seeming attempt to correct some misconceptions about the gird and the power that goes on it.  It is a fine […]
