Abstract:Aerospace structures are often subjected to a broad spectrum of mechanical and/or aerodynamic excitations and, therefore, there is a real need for the development of a modeling technique which can be used for the vibroacoustic analysis, with high fidelity and adequate spatial and spectral… more
Abstract:Representing knowledge in a triple store is trivial, yet querying and visualizing the resulting knowledge is difficult and inefficient when the number of triples is large. Needing to understand the data models from each of the contributing processes and how these data models overlap or interact… more
Abstract:The US military and intelligence community has been successfully fusing the data it gathers into actionable intelligence. However, the volume of data is increasing such that it cannot be processed on a single server, calling for distributed data fusion algorithms that operate across a cloud. As data… more
Abstract:Dimethyl carbonate (DMC) is a high value organic chemical with many potentially important applications. DMC can be made from CO2 directly or indirectly. With the development of CO2 capture and sequestration technology, huge amounts of low cost CO2 will be available as a feed stock. The conversion… more
Abstract:Monomers and other chemical intermediates are typically obtained from non-renewable resources, specifically petroleum. Renewable resources, such as plant derived biomass, may become a significant source of these critical materials but new technology is required for their safe and efficient… more
Abstract:Solvents are a valuable processing tool in the chemical and related industries. Solvent are used to enhance mass transfer, heat transfer and in most cases are a processing aid and eventually are not used in the final product but to enhance the fabrication of the final product. While solvents are… more
Abstract:Ethylene and propylene are the primary feedstocks for the manufacture of polyethylene and polypropylene, respectively. These olefins represent a major component of the polymer manufacturing cost. Consequently, there is significant economic benefit in minimizing losses of unreacted olefin from the… more
Abstract:There is interest to make improvements to foam currently on the market to improve performance (mechanical, thermal, etc.), reduce environmental impacts, and minimize health and safety issues associated with the chemicals and processes used to make foams. Foams made from epoxies, particularly using a… more
Abstract:The US DOE is very interested in promoting on-board vehicular hydrogen storage systems that will allow for a driving range of greater than 300 miles while meeting packaging, cost, safety, and performance requirements. The state-of-the-art H2 storage vessels that meet these requirements are too… more
Abstract:The United States Department of Energy is developing several devices to advance the development of fusion energy. Plans for future major fusion machines will undoubtedly utilize superconducting magnets which operate at 4K or below. Magnets for smaller fusion research devices may also be built… more
Abstract:Mass and volume efficient solar arrays are sought by NASA, DoD and commercial space to enable high power missions from 20-30 kW up to 300 kW. Flexible substrate arrays can have higher specific power (W/kg) and specific volume (kW/m3) than conventional arrays. Typical designs for flexible substrate… more
Abstract:NASA is keen on advancing technologies for lightweight composite cryotanks for heavy lift vehicles for future NASA missions. Two primary challenges must be overcome to enable the use of composite tanks for these new classes of heavy launchers. One is to develop novel, microcrack-resistant, polymer… more
Abstract:The proposed contract effort is for the design, development and proof-of-concept demontration testing of a low cost, pressure-fed liquid rocket booster propulsion system concept. The contract focus will be on four key component technologies in the booster system; (1)composite propellant tanks,… more
Abstract:The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a… more
Abstract:This Small Business Innovation Research Phase I project will demonstrate the technical feasibility of the growth of coilable single-crystal fibers of doped yttrium aluminum garnet (YAG) of sufficient quality to improve the performance of high-power fiber lasers. Single crystal fibers are an… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
