VEHICLES -- Charge on the fly . . .
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. "Our laboratory tests have been successful in transmitting greater than 4 kilowatts," said Laura Marlino of the Energy and Transportation Science Division. "This has been demonstrated with efficiencies in the mid-90s from the transmitting antenna to the load across a 10-inch air gap." [Contact: Ron Walli, (865) 576-0226; firstname.lastname@example.org]
NANOSCIENCE -- Sapphire's sacrifice . . .
Sapphire nanowires grow using an unexpectedly complicated reaction with oxygen atoms changing between partners in vapor, liquid and solid phases. By concentrating on the triple-junction of the three phases, observations captured with high-resolution electron microscopy at the atomic scale, at high temperature and in real time, reveal a growth process that requires the nanowire to sacrifice some of its mass in order to grow longer. While vapor-liquid-solid growth has been studied previously, these are the first studies at atomic resolution. This investigation by an international team that includes Korea's Pohang University of Science and Technology and DOE's Oak Ridge National Laboratory produced a clearer view of the process, allowing improved understanding of the complicated mass transport involved in the growth of nanowires using a liquid catalyst. The work is published in Science. [Contact: Bill Cabage, (865) 574-4399; email@example.com]
