With the 4 billion tons of uranium estimated to be dissolved in the earth & apos;s oceans, an essentially unlimited resource is available to those with easy and affordable access. With decades of research towards the extraction of uranium from seawater, focus has been directed towards the selectivity of the adsorbent material, the cost of the material, and the ability of the adsorbent to be recycl ...

Computer simulations of multi-phase flows are important for many applications. In the proposed work, we plan to advance Eulerian-Lagrangian methods by using Adaptive Mesh Refinement for multi-scale resolutions, and CPU-GPU parallelization to drastically reduce computing time. Eulerian-Lagrangian methods treat the gas/liquid phase as a continuum (Eulerian) fluid, and solid particulates as discrete ...

Tungsten and its alloys are candidates for plasma facing component heat sinks and armor due to their low sputtering rate, high melting point, high thermal conductivity, high strength at elevated temperatures and low tritium inventory. However during service, the plasma facing components will be exposed to a high flux of 14MeV neutrons from the plasma and low energy neutrons from the blanket, whic ...

This Small Business Innovation Research Phase II project proposes a fundamentally new means for biogas/landfill gas desulfurization that produces negligible waste, allows for sulfur recovery/recycling, and provides annualized operating costs that are fraction of current practice. The proposed process consists of two synergistic components: a novel oxidative sulfur removal (OSR) catalytic reactor t ...

This Small Business Innovation Research (SBIR) Phase I project is a feasibility assessment of using ultrathin magnetic iron oxide nanowires as positive contrast agent for magnetic resonance imaging (MRI). Each year, approximately 30 million MRI scans are performed for diagnostic or therapeutic purpose. Two types of contrast agents are routinely administrated to alter the image contrast: T1 positiv ...

This Small Business Innovation Research Phase I project proposes to replace Cu on-chip interconnects with a graphene technology. Nanoscale Cu interconnects that make electrical connections to active devices, mainly transistors, are an essential component of nearly all semiconductor chips. In Complementary Metal Oxide Semiconductor (CMOS) Integrated Circuits (ICs), this Cu interconnect fabric is ap ...
