Abstract:DESCRIPTION (provided by applicant): The objective of this Phase 1 project is to improve an effective treatment of recurrent small-cell lung cancer (rSCLC) by targeting a tumor-specific abnormal receptor, AbnV2 that is a surface-marker of the disease. Currently, there is no effective treatment for… more
Abstract:DESCRIPTION (provided by applicant): New therapies are in development for COPD (endobronchial valves/stents/glue) and asthma (endobronchial thermal ablation). Hyperpolarized xenon-129 (HXe) MRI, a noninvasive method to assess regional lung structure and function, may prove critical in the guidance… more
Abstract:Wide angle neutron analyzers require large volumes of polarized 3He gas that must maintain very high polarization. As these instruments have increased in size, they have outstripped 3He polarization capacity, shortening the run times and adversely affecting. A very high productivity source of… more
Abstract:The 12 GeV upgrade to the Continuous Electron Beam Accelerator Facility at Jefferson Lab will open a new program of nuclear physics experiments, some of which will be conducted with a polarized 3He target. The proposed developments will enable pressurizing polarized 3He from an external large-scale… more
Abstract:The Department of Homeland Security, the Military, and civilian first-responders have an urgent need for sensitive detectors of harmful materials such
as biological and chemical warfare agents, toxic industrial chemicals, and explosives. Handheld instruments must be sensitive, be able to detect a… more
Abstract:Radioxenon monitoring systems are an important tool for detecting nuclear weapon tests around the world. These systems must be reliable and have low contamination potential because nuclear detonations can occur without warning and the opportunity to detect these events is relatively brief. Currently… more
Abstract:Develop a reliable, compact cryogenic thermal switch to enable efficient cryogenic xenon collection in nuclear explosion monitoring systems. The thermal switch can be turned off during xenon removal, when the xenon cryotrap is heated up. This prevents the cryocooler cold head from overheating, and… more
Abstract:Structural ceramics are desirable for high-performance missile radomes due to their excellent strength-to-weight ratio and their ability to withstand high temperatures. Currently, the only way to machine silicon nitride to the tolerances and quality required involves a time-consuming and expensive… more
Abstract:Special Warfare Combat Swimmers operate in a hostile environment characterized by excessive physiologic demands and complete reliance on their equipment. Diver safety and situational awareness can be greatly improved by an integrated system capable of monitoring both diver physiologic status and… more
Abstract:Air-launched, small unmanned aerial systems (SUAS) offer the potential for a tremendous increase in airborne sensing and ground support capability. However, breakthrough power technology is needed to enable these systems to reach their potential. We propose to develop a power system designed to… more
Abstract:Thermoelectric generators (TEGs) offer the potential for simple and efficient conversion of heat directly to electricity. However, efficient power conversion systems that incorporate TEGs present an engineering challenge, requiring an overall system design that balances critical trade-offs between… more
Abstract:Many systems have mechanical couplings and gears that require lubrication and cooling, produce vibration and noise, experience wear, and are unreliable. Magnetic couplings and gears are an emerging technology that can provide superior characteristics for some applications. Although commercial… more
Abstract:ABSTRACT: Advanced space-borne electro-optical payloads require cooling at temperatures of 10 to 20 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at the primary load site, with additional loads at higher temperatures. During this program, we propose to build and test a… more
Abstract:ABSTRACT: Creare proposes to design, develop, test, and deliver an ultra-compact star tracker specifically intended for the CubeSat platform. Our design is based on proprietary"folded optics"technology previously developed by our partner for use in military and commercial optical… more
Abstract:Demonstrations have shown that laser-based stripping systems can effectively and affordably vaporize and strip aircraft coatings in an environmentally friendly manner when coupled to a vapor-removal system. However, all of the laser-based systems in use today are"open-loop"systems that… more
Abstract:ABSTRACT: The performance of modern propulsion devices such as gas turbine main combustors and augmentors is largely dependent on fuel spray dynamics. Fuel sprays, usually involving a liquid jet emanating into a gaseous flow followed by subsequent breakup and atomization, are critically important… more
Abstract:Combustion stability is critical to the performance of augmented military jet engines. Instabilities such as screech can result in reduced augmentor performance, blowout, or even catastrophic failure. Screech remains a difficult problem to predict and mitigate, and its occurrence can limit the… more
Abstract:ABSTRACT: Diagnostic measurements in gas turbine combustors and augmentors are challenging due to the hostile environment and limited optical access afforded by real engines. Probes that are inserted into the flow are generally undesirable because the probes inherently influence the flow and must… 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.
