At the 2002 SAE show in Detroit last March, Southwest Research Institute announced it is forming a consortium for investigating the potential of common lubricating oils to degrade and poison emissions control systems for diesel and gasoline engines. Diesel Aftertreatment Sensitivity to Lubricants, Non-Thermal Catalyst Deactivation (DASL/N-TCD) is a combination of two research projects. "Both will benefit from the research performed under the new consortium," says Bruce Bykowski, assistant director of the Institute's Emissions Research Department. The DASL portion is a parametric study designed to expose diesel emissions-control systems to oil combustion by-products. Researchers measure the deactivation of the emissions control systems as a consequence of oil exposure to determine the effects of lubricating oil components such as sulfur, phosphorus, zinc, and calcium. The N-TCD portion of the consortium explores the mechanisms of emission control system deactivation as a result of oil exposure. Any companies interested in joining the consortium should contact Bykowski at the Emissions Research Dept., Southwest Research Institute, P.O. Drawer 28510, San Antonio, Texas 78228-0510.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
