Mixing Up a Batch of Stronger Metals
April 08, 2015 — Just as a delicate balance of ingredients determines the tastiness of a cookie or cake, the specific ratio of metals in an alloy determines desirable qualities of the new metal, such as improved strength or lightness.
April 02, 2015 — Drivers trying to get to work or home in a hurry know traffic congestion wastes a lot of time, but it also wastes a lot of fuel. In 2011, congestion caused people in US urban areas to travel an extra 5.5 billion hours and purchase an extra 2.9 billion gallons of fuel costing $121 billion.
Collaborative vision, saving sight
March 27, 2015 — Nearly a decade ago, a meeting to explore research collaborations between the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee set the foundation for a company that provides accessible and remote health screenings for patients concerned about diabetic related eye diseases.
March 25, 2015 — For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers’ conventional notion that proteins have a static and well-defined structure.
Five more spring nature walks planned on Oak Ridge Reservation
March 24, 2015 — OAK RIDGE, Tenn., March 24, 2015 – Five more nature walks are planned this spring on the Department of Energy’s Oak Ridge Reservation with themes of frog calls and bat monitoring, wildflowers and forest growth, bird watching, invasive plants, reptiles and amphibians.
The frog calls and bat monitoring walk is scheduled from 7 until 9 p.m.
March 23, 2015 — Rechargeable lithium-ion batteries are commonly found in portable electronics such as cell phones and notebook PCs. They’re also gaining popularity in electric vehicles, where their compact, lightweight build and high-energy storage potential offers a more efficient and environmentally safe alternative to nickel metal hydride and lead-acid batteries traditionally used in vehicles.
Best of both worlds
