A protective coating developed at Oak Ridge National Laboratory can extend the life of costly cutting and boring tools by more than 20 percent, potentially saving millions of dollars over the life of a project. The nanostructure coating, NanoSHIELD, is made from the laser fusing of glassy iron powders. The product was designed for high-wear applications such as tunnel boring, construction, drilling, industrial rock crushing and excavation operations, said Bill Peter, one of the inventors. While the coatings can be applied to any type of steel, its first application was for tunnel boring tools used to cut granite for the Combined Sewer Overflow Tunnel in Atlanta. Also, in 25 years of testing disc cutter coatings at Colorado School of Mines, NanoSHIELD-coated cutters were the first to not spall after one pass at actual rocks.

NUCLEAR ENERGY -- Supercomputer speeds path forward . . .
By using graphic processing units in a test bed for the Titan supercomputer, researchers have more than tripled the speed of a code designed to improve efficiency, longevity and safety of nuclear reactors. The algorithm, dubbed Denovo, sweeps through a virtual reactor to track the location of radioactive particles. When run on graphics processing units, Denovo ran 3.5 times faster than what was possible with ORNL's Jaguar, which uses only central processing units. With this increase, 3D simulations are now within reach, said Tom Evans, who led the Denovo development team. Titan is a GPU/CPU hybrid to be installed over the next several months. This research supports the Consortium for Advanced Simulation of Light Water Reactors (http://www.casl.gov/). [Contact: Dawn Levy, (865) 576-6448; email@example.com]
