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...

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...
