Oak Ridge National Laboratory's Center for Nanophase Materials Sciences, the first of the DOE Office of Science's nanoscience centers, is now open. October 1 marked the first day of the new fiscal year and the nanoscience center's first day with operating funds. Although the first research proposals are just entering the final stage of the review and approval process, the nanoscience center's bank of computers the theory cluster is up and running. The theory cluster will provide nanoscience center researchers and users with computing resources for modeling the theoretical simulations developed in the nanoscience center's Nanomaterials Theory Institute. The close collaboration among nano theorists and computational scientists is indicative of the role theory, modeling and simulation will play in the development of nanoscience.
