The Neutron Spin Echo (NSE) method has provided unique information about the dynamics of soft materials, including confirmation of the de Gennes model of polymer reptation, and quantitative measurement of the bending constants of various membranes. In almost all cases these measurements have been made at small neutron scattering angles, where structural correlations with length scales between 10 n ...

The injection and storage of captured CO2 in coal beds has been suggested as a strategy to reduce industrial emissions of CO2 into the atmosphere. The sequestration process involves the adsorption by coal of injected CO2 and an associated desorption of CH4 whose production can partially offset the operational cost. The acceptance of this strategy depends on: the ability to effectively monitor the ...

DoEs recent emphasis on increasing fuel economy requires electrification of the vehicle powertrain, thus leading to extended range electric vehicles (EREVs), hybrid electric vehicles (HEVs), battery electric vehicles (BEV) and fuel cell electric vehicles (FCEV). All electric propulsion systems require high current, high-voltage (600 V-1200 V), low-loss power semiconductor switches. Present electri ...

Society at large and DOE in particular have an interest in the continued development and refinement of a smart grid infrastructure that more efficiently and reliably matches electrical resources to demands. While technological advances in recent years have improved the smart grid, these advances have been limited by a lack of granularity of data (e.g. environmental conditions at multiple locations ...

This SBIR/STTR project delivers an ultra-low power structural health monitoring (SHM) system that uses autonomous, wirelessly embedded sensors to monitor and assess structural integrity in wind turbine blades. EASE features impedance-based active SHM, which is highly sensitive to damage like cracks, delimitations, mass variations, fastener failures and stiffness changes. Blades are the only wind t ...

One of grand challenges in nanoscience and nanotechnology is to achieve fundamental under- standing of the dynamic evolution of materials in actual operating environment, non-equilibrium conditions, or undergoing chemical reactions at the nanoscale. This requires forefront advances in imaging and analysis techniques that combine nanometer-scale spatial resolution, optical excitation and spectrosco ...

Small Angle Neutron Scattering (SANS) has been an extremely productive materials science probe for several decades and is used extensively by researchers studying a wide range of subjects, including polymers, ceramics, metals and biological macromolecules and functions. However, it is limited to length scales from 1 to 100 nm and requires highly collimated and relatively monochromatic neutron beam ...

Transmission electron microscopy (TEM) is one of the primary tools for biological and materials characterization; however, there is an overarching need to push TEM temporal resolution into a ps-range to study physical processes on their fundamental spatial and temporal scales. With state-of-the-art TEM, however, it is not possible to capture a single image with a temporal resolution better than 10 ...

Spectroscopy in the long-wave infrared (LWIR) wavelength region (8 to 12

To increase the utilization of electric vehicles, the US Department of Energy is seeking to reduce the cost of electric vehicle batteries to less than $125/kWh by 2022. To achieve this goal, the costs of cathode materials, which account for approximately 30% of the cost of vehicle batteries, must be reduced significantly. To address the challenge of lowering the costs of advanced lithium battery c ...
