(PhysOrg.com) -- First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. http://www.physorg.com/news177689867.html Nanotechnology Tue, 17 Nov 2009 14:22:12 EST news177689867 (PhysOrg.com) -- Researchers at the Georgia Institute of Technology have won a $6.5 million grant to develop improved components that will boost the efficiency of electric propulsion systems used to control the positions of satellites and planetary probes. http://www.physorg.com/news175365546.html Nanotechnology Wed, 21 Oct 2009 18:30:01 EST news175365546 (PhysOrg.com) -- In two separate studies, Princeton-led teams of scientists have found a new type of `light-like` electron and visualized for the first time another type that doesn`t bounce back when material imperfections are encountered on the surface of special insulators. The discoveries advance the fundamental understanding of condensed matter physics and may have implications for the development of computing devices millions of times faster than today`s most powerful computers. http://www.physorg.com/news169129727.html Physics Mon, 10 Aug 2009 13:38:16 EST news169129727 (PhysOrg.com) -- New work by condensed-matter theorists at the Stanford Institute for Materials and Energy Science at SLAC National Accelerator Laboratory points to a material that could one day be used to make faster, more efficient computer processors. http://www.physorg.com/news161615953.html Physics Fri, 15 May 2009 14:21:02 EST news161615953 (PhysOrg.com) -- An international team of scientists led by a Princeton University group recently discovered that on the surface of certain materials collective arrangements of electrons move in ways that mimic the presence of a magnetic field where none is present. The finding represents one of the most exotic macroscopic quantum phenomena in condensed-matter physics: a topological Quantum Spin Hall effect. http://www.physorg.com/news153672136.html Physics Thu, 12 Feb 2009 14:43:03 EST news153672136 (PhysOrg.com) -- When water transforms into steam, or magnetized iron changes to demagnetized iron, Katsushi Hashimoto explains to PhysOrg.com, a phase transition is taking place: `Classical phase transitions…often share many fundamental characteristics near the critical point. Quantum phase transitions also show universal critical behaviors, which are affected not only by temperature but also by quantum mechanics.` http://www.physorg.com/news150988279.html Physics Mon, 12 Jan 2009 13:11:19 EST news150988279
