A droplet's pancake bounce

Studies of the impact a droplet makes on solid surfaces hark back more than a century. And until now, it was generally believed that a droplet's impact on a solid surface could always be separated into two phases: spreading and retracting. But it's much more complex than that, as a team of researchers now reports.

Study explores nanoscale structure of thin films

Scientists discuss a new way to apply a widely used local-structure analysis tool - known as atomic pair distribution function (PDF) analysis - to x-ray scattering data from thin films, quickly yielding high-quality information on the films' atomic structure. The work creates new avenues for studies of nanocrystalline thin films.
