Biodiesel - Ultrasonic remedy
December 01, 2010 — A significant barrier to greater use of biodiesel could be blasted away with a proprietary approach developed by a team of researchers led by Mike Kass of Oak Ridge National Laboratory's Energy and Transportation Science Division.
Transportation - Single-wides save fuel
December 01, 2010 — Tractor-trailer trucks may leave a different "footprint" in the near future. Heavy trucks outfitted with single wide-based tires instead of the conventional dual tires are more fuel efficient, according to a study sponsored by DOE's Office of Vehicle Technologies.
Data - Finding feelings
December 01, 2010 — A prototype data-analysis software developed at Oak Ridge National Laboratory could help track potential terrorist groups by uncovering hidden meaning in the group's written interactions. The method can extract emotional content known as affective meaning from unstructured text documents like blogs, emails, tweets and chat feeds, said Jack Schryver, co-developer of the ORNL tool.
Biometrics - ID from afar
December 01, 2010 — Unsuspecting subjects could be identified in mere seconds with a novel recognition system being developed by researchers at Oak Ridge National Laboratory. Unlike conventional technologies that look at a facial feature or the iris, ORNL's off-angle multi-modal biometric recognition system captures several features — iris, face, ears, gait and soft biometrics at a distance.
Vehicles - Charge on the fly
November 05, 2010 — A prototype charging system for electric and hybrid vehicles is helping demonstrate a technology that could one day play a key role in the electrification of America's highways. The bench-scale prototype developed at Oak Ridge National Laboratory is allowing researchers to quantify the power transfer parameters necessary to wirelessly charge stationary and moving vehicles.
Nanoscience - Sapphire's sacrifice
November 05, 2010 — Sapphire nanowires grow using an unexpectedly complicated reaction with oxygen atoms changing between partners in vapor, liquid and solid phases.
Diesels - Joule of a milestone
November 05, 2010 — When Fuels, Engines and Emissions Research Center researchers at Oak Ridge National Laboratory achieved a 45 percent brake thermal efficiency in a multi-cylinder engine, they demonstrated a new potential for passenger-size diesel engines.
Supercomputing - Three-dimensional waste plumes
November 05, 2010 — A research team led by Peter C. Lichtner of Los Alamos National Laboratory (LANL) is using the Oak Ridge Leadership Computing Facility's (OLCF's) Jaguar supercomputer, located at Oak Ridge National Laboratory (ORNL), to build a three-dimensional model of an underground uranium waste plume at the Hanford Site's 300 Area, only a few miles from the city of Richland, WA.
Data - Tracking trucks
November 05, 2010 — A vehicle monitoring study at Oak Ridge National Laboratory could help transform energy-intensive vehicles like transit buses and utility trucks into energy-efficient equipment. ORNL researchers have installed data acquisition and wireless communication systems on several East Tennessee heavy vehicles to take a closer look at how the machines perform in real time.
Nano - World's smallest antenna
September 30, 2010 — Instead of the conventional long piece of metal or dipole antenna, electronic devices of tomorrow could incorporate an antenna no bigger than a gnat. This is made possible by a design that allows an electrically charged nano-mechanical oscillator to be tuned to specific electromagnetic waves.
