Abstract:The electricity produced from fossil fuels is essential to the worlds prosperity and security. On the other hand, increasing atmospheric CO2 concentration caused by the fossil fuel combustion are causing concerns regarding global warming. Although there are several methods for… more
Abstract:Synthesis gas, a mixture of H2 and CO, is one of the top-ten platform chemicals produced from biomass and can be used to produce fuel-ethanol. However, existing heterogeneous catalysts have only a low selectivity for ethanol and produce too much low-value methane. As a result, the production of… more
Abstract:TDA Research Inc. has developed a catalyst that will enable mixtures of coal and biomass to be co-gasified to produce synthetic fuels. Our catalyst exhibits resistance to deactivation that is better than existing commercial catalysts for this application. By mixing agricultural waste with coal to… more
Abstract:DHS requires the ability to respond to an attack with biological agents. Specifically, it requires a decontaminant to kill anthrax spores on building
exteriors and interiors, and other surfaces. In this proposal we describe an innovative bio-agent decon technology that is particularly suitable for… more
Abstract:ABSTRACT: Current aircraft fuel tank coatings provide excellent corrosion protection but do so by incorporating chromates. Unfortunately, these hexavalent chromates are known carcinogens and their use and disposal is strictly regulated. An ideal aircraft fuel tank coating would provide effective… more
Abstract:The corrosion of military equipment and facilities is a significant and ongoing problem. In total, corrosion cost the Department of Defense $23 billion annually and is the number one cost driver in military life-cycle costs. The effective monitoring of aircraft structural health is essential to… more
Abstract:TDA Research, Inc. (TDA) proposes a new route for the chemical synthesis of the explosive compound CL-20. CL-20, which is an acronym for 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane, is an oxidizing explosive nitramine molecule that has higher energy density than the widely used… more
Abstract:Ablative thermal protection system (TPS) materials are widely used in spacecraft and missiles that re-enter the atmosphere. Since they constitute a significant portion of the re-entry body"s mass, improving their performance could greatly reduce mission cost or increase payload. The ablative… more
Abstract:ABSTRACT: Electrolytic Hard Chrome (ECH) is the standard coating method for 4XXX steels used in actuators and depot-based repair of damaged items. The properties of EHC coatings are excellent, and as a result EHC coatings have been used for more than 50 years. Unfortunately, EHC plating uses… more
Abstract:Human exploration of Mars, as well as unmanned sample return missions can benefit greatly from use of propellants and life-support consumables produced from the resources available on Mars. The first major step of any in-situ propellant production system is the acquisition of carbon dioxide from… more
Abstract:An on-board oxygen concentrator is required during long duration manned space missions to supply medical oxygen. The commercial medical oxygen generators based on pressure swing adsorption (PSA) are large and highly power intensive. TDA Research, Inc. (TDA) proposes to develop a small, lightweight… more
Abstract:TDA Research proposes to develop a computer-controlled lightweight and compact device for aerobic and resistive training (DART) to counteract muscular atrophy and bone loss and to improve the overall wellness of astronauts operating in microgravity. The DART will be able to provide resistive loads… more
Abstract:The increasing frequency of International Space Station (ISS) egress operations contaminates the spacecraft environment with propellant residues (such as anhydrous hydrazine) and their decomposition by-products, as well as coolants such as ammonia and Freon. NH3 and N2H4 have a 24 hour Spacecraft… more
Abstract:TDA Research, Inc. (TDA) proposes to develop a post-fire air purification system that consists of a particulate removal assembly, a sorbent bed to remove the combustion by-products generated by low intensity fires (such as HCN, HCl, SO2 and NH3) and an ambient temperature oxidation catalyst to… more
Abstract:Diesel engines are more efficient than gasoline powered engines, but have high emissions of particulate matter, nitrogen oxides and at times volatile organic compounds. New low temperature catalyst materials are needed for exhaust after-treatment systems that can meet the increasingly stringent… more
Abstract:DESCRIPTION (provided by applicant): Dental caries are the most common childhood disease in the United States. Dental sealants are materials that are applied to the pits and fissures of healthy teeth to prevent dental caries or other forms of decay. This method prevents bacteria ingress and acid… more
Abstract:DESCRIPTION (provided by applicant): New and improved technologies are needed for monitoring perchlorate contamination in groundwater. TDA Research Inc. proposes a new portable sensor platform for in-the-field monitoring of the perchlorate anion, ClO4-, for which the recommended remediation goal is… more
Abstract:ABSTRACT: The development of weapons that can travel at hypersonic speeds is becoming a high priority to the US Air Force. A key technology needed for the continued development of these propulsion systems is the ability to cool the combustor by flowing fuel through channels machined in the walls. … more
Abstract:Spacecraft and remote vehicle operations demand a high level of responsiveness in dynamic environments. During operations it is possible for unexpected events and anomalies to disrupt the mission schedule, and in the case of critical faults, even threaten the health and safety of the spacecraft. … 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.
