The shape of melting in two dimensions

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

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.

Neutrons identify critical details in bacterial enzyme implicated in gastric cancer

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Neutron analysis at the Department of Energy's Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer. Understanding the details of this enzyme, and thus the Helicobacter pylori bacteria's metabolism and biological pathways, could be central to developing drugs that act against H. pylori, but that do not attack the stomach's useful bacteria.

Ceramic matrix composites take flight in LEAP jet engine

DOE/Oak Ridge National Laboratory

Ceramic matrix composite (CMC) materials are tough, lightweight and capable of withstanding temperatures 300-400 degrees F hotter than metal alloys can endure. A quarter-century ago, the US Department of Energy began a program, led by DOE's Oak Ridge National Laboratory, to support US development of CMC materials. This year, LEAP, a new aircraft engine, became the first widely deployed CMC-containing product. CFM International, a 50/50 joint venture of Safran and GE, manufactures LEAP.
