MATERIALS -- Next-generation electronics . . .
Changing the behavior of a material isn't big magic it's nanoscale chemistry. Alejandro Lopez-Bezanilla used the computing power of Oak Ridge National Laboratory's Jaguar supercomputer, America's fastest, to study the effects of adding oxygen, sulfur and hydrogen to nanoribbons made of boron nitride. The added elements changed the behavior of boron nitride a good insulator into that of a metal. That makes the material promising for faster computer chips and smarter cell phones. Stable, inexpensive boron nitride can serve as a substrate to support blazing-fast graphene, a material being studied for next-generation electronics. Graphene and boron nitride can be created in 1-atom-thick sheets and cut into ribbons to carry electrons and their on/off electronic messages.

SUPERCOMPUTING -- Optimization tools . . .
An upgrade is transforming Oak Ridge National Laboratory's Jaguar supercomputer, America's fastest, into Titan, a next-generation supercomputer that will employ the latest AMD Opteron central processing units as well as NVIDIA Tesla graphics processing units energy-efficient processors that accelerate specific types of calculations in scientific application codes. Titan's hybrid architecture will bring fundamental changes for researchers from academia, industry and government that employ computing resources. Members of the Oak Ridge Leadership Computing Facility's Application Performance Tools group are collaborating with Allinea, CAPS Enterprise, and the Technical University of Dresden to develop software tools to help with new challenges presented by Titan's design.
