A multi-institutional team used resources at the Oak Ridge Leadership Computing Facility to catalog how desert plants photosynthetic processes vary. The study could help scientists engineer drought-resistant crops for food and fuel.

Predictive Power

The Consortium for Advanced Simulation of Light Water Reactors carried out the largest time-dependent simulation of a nuclear reactor ever to support Tennessee Valley Authority and Westinghouse Electric Company during the startup of Watts Bar Unit 2, the first new US nuclear reactor in 20 years. The simulation was carried out primarily on OLCF resources.

Advantage: Water

When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the slightest advantage, like the score in a highly competitive tennis game.
