Important Similarity Between Behavior of Polycrystalline Materials and Glasses

Better predictions of how many valuable materials behave under stress could be on the way from the National Institute of Standards and Technology (NIST), where scientists have recently found evidence* of an important similarity between the behavior of polycrystalline materials-such as metals and ceramics-and glasses.

Shape Matters in the Case of Cobalt Nanoparticles

Shape is turning out to be a particularly important feature of some commercially important nanoparticles-but in subtle ways. New studies* by scientists at the National Institute for Standards and Technology (NIST) show that changing the shape of cobalt nanoparticles from spherical to cubic can fundamentally change their behavior.

Biophysicists Create Nonstick Gold Surfaces and Laser-Safe Gold Nanoposts

Biophysicists long for an ideal material-something more structured and less sticky than a standard glass surface-to anchor and position individual biomolecules. Gold is an alluring possibility, with its simple chemistry and the ease with which it can be patterned.
