D.O.E. is particularly interested in methane measurements in the Arctic where rapid climatic change… more
Abstract:Knowing atmospheric 13CO2/12CO2 ratios precisely is important to understanding biogenic and anthroprogenic sources and sinks for carbon. However, instruments currently available have attributes that are not favorable for distributed UAV deployment; they are large, require a lot of power, are very… more
Abstract:Monitoring the root systems of plants is essential to improving models of crop productivity, soil carbon sequestration and biogeochemical cycling. Fine roots (considered to be smaller than 1-2 mm in diameter) are the dominant component of this system, with roots & lt;0.2 mm in diameter often… more
Abstract:Past industrial practices have resulted in groundwater that is contaminated by heavy metals. Long-term monitoring and maintenance is one of the largest costs of environmental management. This project is developing a compact analyzer for measuring chromium ions in ground water that should… more
Abstract:The Compound Specific Analyzer?Combustion Products, used on the International Space Station as a warning monitor of smoldering or combustion events, is being phased out of service. Southwest Sciences Inc. proposes to develop a replacement laser-based analyzer using wavelength modulation… more
Abstract:This Phase I research project will investigate a novel method of operating an atomic magnetometer to simultaneously measure total magnetic fields and vector magnetic fields. Magnetometry has provided critical scientific information throughout the history of space exploration. The ideal magnetic… more
Abstract:Ensuring a safe air environment in manned spacecraft is critical to the success of all missions. Exposure to hazardous chemical species threatens the well-being of the crew and prevents them from fulfilling their tasks. While a wide variety of sensors currently are available to monitor such… more
Abstract:The development of rocket-based and turbine-based combined cycle engines are a high priority for transportation into space. In order to test components and systems, and certify life cycles for these engines, non-intrusive flow diagnostics are required. In particular, high-speed measurements of… more
Abstract:DESCRIPTION (provided by applicant): Thyroid cancer is the most common type of endocrine malignancy. New thyroid cancers patients are identified daily, and most patients live for decades following diagnosis. Thyroglobulin (TG) levels in the sera or in fineneedle biopsies of thyroid cancer patients… more
Abstract:The U.S. portion of the International Space Station (ISS), which has been designated by Congress as a National Laboratory, holds great potential for a broad spectrum of researchers who are eager to take advantage of its unique scientific research facilities. The Light Microscopy Module (LMM), which… more
Abstract:Rechargeable batteries self discharge while in storage, and when allowed to remain at an extremely low state of charge for a long period of time, can be damaged permanently and then must be discarded. The USMC finds it far too costly and impractical to perform manual maintenance recharges every 3 to… more
Abstract:DESCRIPTION (provided by applicant): Techshot, Inc. has successfully completed SBIR Phase I and Phase II research demonstrating that magnetically labeled porcine islets of Langerhans can be isolated from contaminating exocrine tissue by flow sorting usinga quadrupole magnetic separator ( Quadrasep )… more
Abstract:There is no rad hard SDRAM currently available to support DDR2 and DDR3 applications. Space Micro proposes to build a radiation hardened by design (RHBD) SDRAM memory, using a modified version of our HF-Core Memory Controller to solve all the single event effects issues (SEU, SEFI and multiple bit… more
Abstract:Space Micro proposes to develop a radiation hardened, monolithic, heterogeneous processor for space imaging and radar systems. High performance processors are needed because many space systems generate copious amounts of sensor data at high data rates. The extraction of information from such data… more
Abstract:Radiation-hardened non volatile memory is needed to store the golden copy of the image(s) has not kept pace with the advances in FPGAs.

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.
