The quantum jiggling that molecules experience even at the lowest temperatures–motion associated with the uncertainty principle–is not as tiny as researchers assumed and may be detected in the scattering of light through a liquid.

Researchers measured the interaction between surface plasmons–electron waves on metal surfaces–with excitons, excited states of electrons in semiconductors. Understanding the communication between the two could improve solar cells and speed up electronic and optical devices.

Slow-moving nanoparticles hitting a surface bounce away, but surprisingly, fast-moving ones stick. New simulations explain that the sticking occurs because the fast particles absorb the collision energy by transforming their atomic structure.

Theorists predict that collisions can briefly create a beryllium nucleus in which neutrons bind two clumps of particles together the way electrons bind atoms into a molecule–in three very different configurations.
