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.

A new theory on the interactions of nanoparticles with laser light predicts some surprising effects when more than one particle is involved, such as a particle being drawn toward the source of the beam, against the flow of photons.
