The combination of X-ray absorption spectroscopy (XAS) with x-ray emission spectroscopy (XES) provides unique diagnostic analysis of both the structure and chemical composition of complex heterogeneous materials. The penetration of X-rays make this method ideal for studying and optimizing material properties under realistic, real time reaction conditions with simultaneous analysis of r ...

NOVA Scientific proposes the development of efficient position sensitive detectors capable of time-tagging epithermal energy neutrons with high accuracy and efficiency. These devices will be able to perform energy-resolved imaging at the pulsed neutron sources and detect every neutron with spatial resolution of & lt; 60 m and timing resolution & lt; 1 s for thermal neutrons and & lt;100 ns for epi ...

The remediation of underground nuclear waste storage tanks and associated disposal cribs and trenches at the U.S. Department of Energy (DOE) nuclear waste storage facilities, together with the associated needs to characterize and monitor the chemical compositions of the contaminants, presents a major scientific challenge. Several of these storage tanks are leaking, and significant quantities of w ...

Coal-fired power plants are a very large, concentrated, and stationary source of carbon dioxide emissions, and represent the best target to address the problem of increasing CO2 emissions through use of carbon dioxide capture, utilization, and storage technologies. The overall objective of the proposed Phase II research is to continue development of and enhance the hybrid sorbent tec ...

The non-aqueous ionomer dispersion technology invented at Los Alamos National Laboratory (LANL) has demonstrated great potential to significantly improve the lifetime of proton exchange membrane (PEM) fuel cells and electrolyzers. However, further validation and improvements are needed to make this technology commercially viable. The overall objective of this project is to further devel ...

This Phase II Small Business Innovation Research project targets the development of a technology for segregating fuelbased contaminants (char and ash) from oxygen carrier material in the context of chemical looping combustion application. In chemical looping, the wellmixed solids that flow from the fuel reactor consisting of char, ash, and oxygen carrier particles cannot be completely separated in ...

Existing methodologies for attrition evaluation of oxygen carriers in Chemical Looping Combustion systems do not adequately reflect the unique process conditions to which oxygen carriers are exposed, specifically high temperatures and cyclically reacting oxidizing and reducing atmospheres. This proposed Small Business Innovation Research (SBIR/STTR) project targets the development of novel equipme ...

Current methods for manufacturing carbon fiber rely on high temperature ovens for the stabilization/oxidation and carbonization steps, which tend to be slow and energy intensive. As such, carbon fiber composites are expensive then steel, which limits their use in costsensitive, highvolume industrial applications such as automobiles, oil and gas, and infrastructure. To reduce energy consumption and ...

"High brightness and high average power Free Electron Lasers known as x-ray FELs, developed by DOE, are intently desired by the scientific community for their unique capabilities and for the opportunities they enable in the medical and biological sciences, such as imaging biological molecules or chemical reactions. Beam optics codes (particularly Particle-in-Cell codes) couple non-uniformity and s ...

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...
