Better Materials through Clusters
Better materials through clusters Though limited to a cast of 90 or so atomic elements, chemists can build a veritable universe of molecules and materials. Materials scientists have been learning how to assemble tens to many thousands of molecules...
Cold Traps for Ion Crystals, Solid Plasmas
Cold traps for ion crystals, solid plasmas Taking an electron away from an atom produces a positively charged ion. Such atomic ions repel each other. When they are cooled to temperatures near absolute zero and held in electromagnetic traps, the...
Dif-Fusion: Beware the Ideas of March
Dif-fusion: Beware the Ideas of March More than 40 sunrises powered by old-fashioned fusion have passed since the day B. Stanley Pons and Martin Fleischmann told the world they may have found a new, room-temperature route to potentially practical...
