Solar - Bridging the gap
December 09, 2009 — Titanium dioxide, the same inexpensive white pigment that protects us from sunburns, can be converted into a material that absorbs sunlight and could greatly increase the efficiency of solar energy cells. Until now, however, researchers had not been able to overcome the inherent wide band gap associated with the different energy levels, or bands, of the electrons.
Nuclear Energy- Record fuel burn
December 09, 2009 — Coated particle fuel fabricated at Oak Ridge National Laboratory, in cooperation with Idaho National Laboratory, General Atomics, and the Babcock & Wilcox Company, has set a world record for advanced high temperature gas-cooled reactor fuel.
Physics - Exploiting strain fields
December 09, 2009 — Electronic devices of the future may benefit from a fundamental discovery that allows researchers to customize the electronic properties of complex materials such as single-crystal thin-film structures.
Transportation - Gone hybrid
November 05, 2009 — Fuel economy ratings for the new 2010 model year automobiles are now posted at the http://www.fueleconomy.gov web site, which Oak Ridge National Laboratory developed and maintains for the U.S. Department of Energy and the U.S. Environmental Protection Agency.
Materials - Ferroelectric fury
November 05, 2009 — By discovering a technique to guide the ferroelectric switching process in bismuth ferrite, a team led by Oak Ridge National Laboratory's Nina Balke has moved one step closer to developing more rugged memory and logic devices. One key to the success is that the material has both electrical and magnetic properties at the same time, which is unusual.
Manufacturing - Holey truck frames
November 05, 2009 — Heavy trucks are a little less heavy but just as safe and rugged because of steel rail frames provided by Metalsa Roanoke, which enlisted the help of Cam Hubbard and the High Temperature Materials Laboratory User Program at Oak Ridge National Laboratory.
Nanoscience - Using neural networks
November 05, 2009 — A new approach to crunching massive volumes of data uses neural networks, an architecture of multiple elements that is figuratively taught to pool imbedded information into results, like an artificial brain.
Materials - Graphene cleanup
October 13, 2009 — Graphene, a single-layer sheet of graphite, has potential as a remarkable material, particularly for electronics and composite applications. However, working with the material leaves molecular-scale rough edges, which spoil its properties.
Transportation - IntelligentFreight hits highway
October 13, 2009 — Information sharing technologies at the heart of Web 2.0 are being integrated into an Oak Ridge National Laboratory freight tracking system that could revolutionize the industry.
Neutron Sciences - TOPAZ beam line
October 13, 2009 — Construction and installation has been completed recently on the newest instrument at the Department of Energy's Spallation Neutron Source at Oak Ridge National Laboratory. The Single-Crystal Diffractometer, also known as TOPAZ, will greatly expand the range of materials explored in chemistry, earth sciences, materials science and engineering, solid-state physics and biology.
