Scientific Reports ORNL study examines tungsten in extreme environments to improve fusion materials
'We're trying to determine the fundamental behavior of plasma-facing materials with the goal of better understanding degradation mechanisms so we can engineer robust, new materials,' said materials scientist Chad Parish of Oak Ridge National Laboratory. He is senior author of a study in the journal Scientific Reports that explored degradation of tungsten under reactor-relevant conditions. Learning about how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials.

Public Release: 1-Feb-2017 The shape of melting in two dimensions
As part of her team's research into matter's tendency to self-organize, Sharon Glotzer of the University of Michigan ran a series of hard particle simulations to study melting in two-dimensional (2-D) systems. Specifically, the team explored how particle shape affects the physics of a 2-D solid-to-fluid melting transition.
