Abstract:DESCRIPTION (provided by applicant): Current health care modalities for humans diagnosed with either precancerous actinic keratoses or skin cancers (including basal and squamous cell carcinomas) primarily involve surgical excision of the lesions or chemical or photodynamic burning of the affected… more
Abstract:US oil shale reserves contain a vast carbon energy source which if produced in an economically feasible and environmentally safe manner - would provide part of the solution for future US energy needs. While no commercial production of oil shales currently occurs, in situ retorting is generally… more
Abstract:The ability to effectively use large amount of automatically collected geophysical and hydrological data is relevant for both operational (clean up related) and scientific Department of Energy needs. Currently, data from geophysical monitoring systems at DOE sites requires extensive manual data… more
Abstract:DESCRIPTION (provided by applicant): As measured by the National Crime Victimization Survey (NCVS), people with disabilities age 12 and older experienced approximately 716,000 nonfatal violent crimes and 2.3 million property crimes in 2007. Rape, sexual assault, robbery, aggravated assault and… more
Abstract:DESCRIPTION (provided by applicant): The purpose of this application is to expand upon our Phase I work and further develop a fully-interactive multimedia (IMM) computer-based HIV/AIDS prevention curricula for adult women with mild intellectual disabilities (ID) (I.Q. approximately 55 through 75).… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project will demonstrate the feasibility of using a novel enzyme from a marine bacterium as part of a process to convert biomass to ethanol. The Trillium laboratory has preliminary data that indicates that this enzyme has unique characteristics… more
Abstract:"Cellulosic ethanol is a desirable transportation fuel for environmental and economic reasons. One of the issues limiting the commercialization is the utilization of xylose which is not fermented to ethanol by conventional brewing yeasts. Trillium Fiber Fuels is pioneering the use of xylos… more
Abstract:Combinatorial methods are proposed to develop advanced Aqueous Oxidation Catalysts (AOCs) with the capability to mineralize organic contaminants present in effluents from current and future primary wastewater treatment processes at temperatures less than 70Â?aC, pressures below 20 psig, and contact… more
Abstract:A microgravity-compatible Advanced Air Evaporation System (AAES) is proposed for recovering nearly 100% of water from highly contaminated wastewater without concern for precipitation of organic and inorganic solids. The AAES incorporates reusable wicks, and heat exchange and thermoelectric heat… more
Abstract:Plasma catalytic techniques are proposed for the extraction of oxygen from the abundant carbon dioxide contained in the Martian atmosphere (95% CO2).. The Phase I project will clearly demonstrate the feasibility of achieving these goals by focussing on key aspects of the technology, such as… more
Abstract:Oxygen (O2) contained within waste carbon dioxide (CO2) is a vital resource during long-duration, manned missions that must be reclaimed by Environmental Control and Life Support System (ECLSS) hardware. Current CO2 reduction technology to recapture oxygen as water utilizes the Sabatier reaction,… more
Abstract:DESCRIPTION (provided by applicant): The specific aim of this proposal is to determine if it is feasible to use a polymer-coated shaft in placed of a precision-machined roller die for the purposes of producing braille and tactile graphics. If successful, this project will result in the selection… more
Abstract:NASA has a requirement for a large-area, high-quantum-efficiency, high-throughput optical receiver for ground-, air-, and space-based LIDAR systems. A radiation-hardened direct detection analog LIDAR receiver will be developed to address this need in the proposed STTR program. The rad-hard LIDAR… more
Abstract:Existing photocathode-based technologies for visible and UV instruments lack sensitivity, are bulky, and have limited reliability.

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.
