The work is part of a study to understand the impact of the environment, and contaminants in the environment, on human life and health. Electric bus of the future A new motor controller with advanced soft-switching circuitry developed at DOE's Oak Ridge National Laboratory promises to make electric and hybrid vehicles more practical. The 100-kilowatt inverter and controller, which are being tested aboard an electric bus in Chattanooga, Tenn., represent breakthroughs in several areas, including cost, volume, weight and reliability. The soft-switching circuitry helps reduce damaging power spikes and increases efficiency. Early results are promising, according to ORNL and its partners, Chattanooga Area Regional Transit Authority, Advanced Vehicle Systems and the Electric Transit Vehicle Institute.
Researchers plan to operate the system on a test track and city route and collect and evaluate data.
Gundel first used denuder technology, not normally employed with organic chemicals, to measure tobacco smoke. Standard air samplers fitted with denuders outperformed samplers without them in EPA field studies. Mixing the microcapsules uniformly in soil samples results in true blind or double blind tests to measure the accuracy of a laboratory's analysis. The results can improve soil characterizations, increase efficiency and reduce costs of soil site remediation. The process is inexpensive, too, utilizing commercially available raw materials.
