Understanding the secrets of water on a surface
February 22, 2010 • In Physics Today cover story, Peter Feibelman traces progression of an idea ALBUQUERQUE, N.M. — It may seem a harmless question to ask how molecules of water arrange themselves to cover a surface, but the answer has big consequences. For instance, the drag experienced by water flowing past a surface...

Why huge bands of iron formed billions of years ago on Earth’s surface
November 19, 2009 • Ironing out a longstanding geological puzzle ALBUQUERQUE, N.M. — No one knows why massive formations of banded iron — some ultimately hundreds of kilometers long, like a sleeping giant’s suspenders — mysteriously began precipitating on Earth’s surface about 3.5 billion years ago. Or why, almost 2 billion years later, the...

Yifeng Wang holds a piece of banded iron during a visit to an aquarium. Wang and colleagues have proposed an explanation -- published recently in Nature Geoscience -- for the precipitation of banded iron deposits in the planets oceans billions of years ago.

Sandia announces completion of mixed waste landfill cover construction
November 2, 2009 • ALBUQUERQUE, N.M. – The Environmental Restoration Project at Sandia National Laboratories reports the successful construction of an alternative evapotranspirative cover at the Mixed Waste Landfill (MWL) in September. The 2.6-acre site is located in Technical Area 3 in the west-central part of Kirtland Air Force Base. The protective cover consists...

Magnetic mixing creates quite a stir
October 27, 2009 • ALBUQUERQUE, N.M. – Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create mixing, with only “mixed” success. “In small devices,” says Sandia materials scientist Jim Martin “people have tried all kinds...

Salt block unexpectedly stretches in Sandia experiments
June 22, 2009 • Nanoscopic discovery may have implications for smog, asthma, cloud formation ALBUQUERQUE, N.M. — To stretch a supply of salt generally means using it sparingly. But researchers from Sandia National Laboratories and the University of Pittsburgh were startled when they found they had made the solid actually physically stretch. “It’s not...
