WEST LAFAYETTE, Ind. - A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials ...

Even the simplest molecules are complex creatures. They can vibrate and rotate, and may have a permanent electric dipole moment that enables them to interact over relatively long distances. All these ...

The ancient Greek and Indian philosophers who first conjectured that matter was made of tiny little bits of stuff would not believe that now, more than 25 centuries later, we can actually see them.

Although atomic resolution has been attained previously for AFM imaging of individual atoms in nanotubes and in unit cells of crystals on surfaces, this is the first time all the atom positions and ...

Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Vortex beams made of light or electrons have shown promise for making special types of microscope images and for ...
