Vegetable oil similar to the stuff you use to cook your food may one day fill your cars engine. Researchers at the U.S. Department of Agriculture have developed a chemically modified version of the edible oil that shows promise as a cleaner, renewable alternative to petroleum-based motor oil, while enhancing its protective properties.
Veggie motor oil could eventually be produced cheaper than petroleum-based oil and may help reduce this countrys dependence on foreign oil, the researchers say. Their work was described today at the 225th national meeting of the American Chemical Society, the worlds largest scientific society.
"Vegetable oil is going to have a huge impact on the future by making the world a cleaner, greener place. Our new version is a significant step in that direction," says Atanu Adhvaryu, Ph.D., a chemist with the USDAs National Center for Agricultural Utilization Research in Peoria, Ill., and a lead researcher on the project.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
