At the nanoscale, graphite can turn friction upside down (w/video)

A team of researchers at the National Institute of Standards and Technology has discovered that if graphite is sticky enough, as measured by a nanoscale probe, it actually becomes harder to slide a tip across the material's surface as you decrease pressure - the exact opposite of our everyday experience.

New paper reveals fundamental chemistry of plasma/liquid interactions

Though not often considered beyond the plasma television, small-scale microplasmas have great utility in a wide variety of applications. Recently, new developments have begun to capitalize on how these microplasmas interact with liquids in applications ranging from killing bacteria for sterilizing a surface to rapidly synthesizing nanoparticles.

Physicists crack another piece of the glass puzzle (w/video)

When it comes to physics, glass lacks transparency. No one has been able to see what's happening at the molecular level as a super-cooled liquid approaches the glass state - until now. Emory University physicists have made a movie of particle motion during this mysterious transition.

Center gets small to study nanoparticles in environment

In partnership with researchers from four Midwestern universities and a national laboratory, Robert Hamers hopes to scale the outer walls of living things - their cell membranes - and watch nanoparticles of various compositions, sizes and shapes knock on the door.
