There is significant opportunity for energy efficiency improvements in the industrial and manufacturing sectors in the U.S., both from the production and consumption perspective. Higher energy density battery materials will play a role in both, through improved storage of electricity from renewable sources, the enabling of electric vehicles, and through the development of longer lasting, higher po ...

Ice crystals can form spontaneously from the freezing of water droplets at temperatures colder than -38

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 ...

The cost of dewatering particles is inversely proportional to particle size. Costs dramatically increase as particle size approaches 10

Bright coherent light sources in the soft x-ray region of the spectrum are useful for a variety of applications of interest to DOE in the basic sciences, nanoscience and biology, and for technological applications. At Free-Electron Laser Facilities, peak power output of the x-ray pulses is enhanced by using a mid-infrared laser pulse instead of a near-infrared pulse. The current front end for mid- ...

Hydrogen produced today from coal, natural gas, or biomass must be separated and purified outside the reactors using pressure swing absorption (PSA), a process that requires significant additional space and energy. Placing hydrogen-permeable membranes inside the reactors themselves would allow hydrogen to diffuse out, thereby reducing the cost of hydrogen production. In this Phase I effort, Mainst ...

Spallation neutron source user facilities require reliable, intense beams of protons. The technique of H- charge exchange injection into a storage ring or synchrotron has the potential to provide the needed beam currents. However, the facility operation is limited by the performance of H- ion sources with currents, brightness, reliability and availability that could still be improved. In this pro ...

Typically, high power sources for accelerator applications are many megawatt microwave tubes that may be combined together to form ultra high-power localized power stations. The RF power is then distributed to multiple strings of cavities through high power waveguide systems, which are expensive to produce and to operate, because of reduced efficiency and lower reliability. Magnetrons are the lo ...

A superconducting RF (SRF) power coupler capable of handling 500 kW CW RF power at 750 MHz is required for present and future storage rings and linacs. There are over 35 coupler designs for SRF cavities ranging in frequency from 325 to 1500 MHz. Coupler windows vary from cylinders to cones to disks and RF power couplers will always be limited by the ability of ceramic windows and their matching ...

Muon beam ionization cooling is a key element in the design of next-generation low-emittance and high-luminosity muon colliders. New approaches in that cooling could greatly improve the performance and capabilities of these colliders. To obtain low-emittance muon beams, a new concept is being developed that combines ionization cooling in a Helical Cooling Channel (HCC) with parametric resonances. ...
