Crawford Elliott and his PhD student Laura Zaunbrecher from Georgia State University, have been examining the adsorption mechanisms of metal cations onto soils and sediments. This effort is especially important for the environmental treatment of chemical and radioactive contaminants, including the fission product cesium-137—which is […]
Carlos Michelen (in Sandia’s Water Power Technologies Dept.) and a team of National Renewable Energy Laboratory (NREL) researchers (Michael Lawson, Braulio Garzon, Fabian Wendt, and Yi-Hsiang Yu) won the Offshore Mechanics and Arctic Engineering (OMAE) 2015 Hydraulic Modeling Competition during the 34th ASME International Conference on Ocean, Offshore, and Arctic Engineering in St. Johns, Newfoundland, Canada, in June. The NREL and Sandia team entered the competition and modeled the experimental device (described below) using both
Sandia researchers are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles.
This month, engineers lifted Sandia’s continuously recirculating falling-particle receiver to the top of the tower at the National Solar Thermal Test Facility (NSTTF), marking the start of first-of-its-kind testing that will continue through 2015. The Sandia-developed falling-particle receiver drops sand-like ceramic particles through the NSTTF’s concentrated sunlight beam, capturing and […]

Measures for keeping nuclear materials out of the wrong hands can be as straightforward as a stout post beam designed to stop massive, speeding trucks in their tire tracks—or they can be as complex as fencing draped with a web of sensors so acute they can differentiate the movements of men from those of jackrabbits. Multiple systems and strategies are necessary to safeguard nuclear materials in nonmilitary facilities such as hospitals, clinics, and nuclear power […]
