Abstract:The proposed research effort will develp a new, lower-cost and more environmentally benign sorbent system to remove mercury from the flue gases produced by waste combustion incinerators. Current removal systems use dry sorbent injection of activated carbon, which is collected in the fabric filter… more
Abstract:This Small Business Innovation Research Phase I project aims to develop a new process to manufacture small fullerenes having a size less than conventional fullerenes. Prior research performed has lead to the successful development and commercialization of a combustion process for making fullerenes,… more
Abstract:This Small Business Innovation Research Phase I project aims to develop biocidal nanoparticle additives for thermoplastics, in particular, poly (vinyl chloride). Biocides can now be added as a component during the plastic manufacturing process to make it inherently resistant to microbial attack. PVC… more
Abstract:In February 2004 NASA released "The Vision for Space Exploration". The important goals include extending human presence in the solar system culminating in the exploration of Mars and other remote destinations. To accomplish this goal, affordable, new technologies to support long-term missions must… more
Abstract:The corrosion of steel has widespread economic and environmental effects, and the annual cost of corrosion exceeds $275 billion. About 49% of U.S. steel production goes to replace corrodded matal parts and consumer goods. Corrosion also has a significant impact on the environment. Structures such… more
Abstract:DESCRIPTION (provided by applicant): Endohedral metallofullerenes are spherical fullerene carbon cages confining one or more metal atoms in their interior spaces. Biomedical applications exploiting special properties of metallofullerenes in different areas are promising, including diagnostic and… more
Abstract:Liquefied methane is a promising fuel for space launch vehicles because it has a high specific impulse, excellent cooling capacity, and is very resistant to coking and soot formation. Unfortunately, it is also a very stable molecule and therefore ignition delay times can exceed combustor residence… more
Abstract:Current decontamination systems for chemical warfare (CW) agents require large volumes of liquid, are bulky and corrosive, and a catalytic decontaminant capable of decontaminating large amounts of agents with a small amount of catalyst would be highly desirable. The U.S. Government has sponsored… more
Abstract:Surfaces and enclosed spaces (such as vehicle crew compartments) that are contaminated with chemical warfare (CW) or biological warfare (BW) agents must be rapidly decontaminated to allow continued operations. Unfortunately, all of the current decon technologies have significant disadvantages, such… more
Abstract:Since their identification in the early `80s, pathogenic and infectious proteins called prions have been linked to a number of degenerative neurological diseases in humans and animals. The diagnosis and tracking of these transmissible spongiform encephalopathies (TSEs) is difficult because it can… more
Abstract:Since pure aluminum is soft and has only moderate strength, aluminum alloys are used for aerospace and other structural applications. However, the copper in these alloys significantly reduces the corrosion resistance of the aluminum. The standard pretreatment used to clean aluminum alloys before… more
Abstract:NASA's planned future missions set stringent demands on the design of the Portable Life Support Systems (PLSS) used to cool the astronaut and provide them with air. Dramatic reductions in weight, decreased reliance on supplies and greater flexibility on the types of missions are all needed. The… more
Abstract:The performance of rockets and missiles is almost always limited by the energy density of the propellant, and the development of new types of higher energy density components remains an important research challenge. The energy density of hydrocarbon propellant components is normally increased by… more
Abstract:DESCRIPTION (provided by applicant): Quantum dots are recognized as the core materials of a new generation luminescent agents for biolabelling applications. This project will establish proof-of-concept for a new class of non-toxic, metal free quantum dot-like materials. We will synthesize these new… more
Abstract:This SBIR Phase II research project will develop energy-aware compiler techniques to reduce power and energy consumption in microprocessors, without affecting performance. A key principle behind this approach is to use speculative information available at compile time to reduce power and energy… more
Abstract:The semantic web is a worldwide effort aimed at attaching machine-understandable semantic information to content, and to develop applications that make use of that information. SWRL (Semantic Web Rule Language) is a logic programming language that is becoming a standard for providing reasoning… more
Abstract:Adversaries reverse engineer weapons systems to replicate a system's advanced capabilities or discover its weaknesses. The software in advanced civilian products is similarly reverse engineered by competitors. Many of these critical systems are real-time systems. The restrictions of real-time have… more
Abstract:As hardware platforms age, manufacturers are less willing to support them and related technologies. Legacy weapons systems must eventually be modernized. Re-implementation of the legacy software by hand is prohibitively expensive. A system is needed for automatically translating software written in… more
Abstract:The problem of supporting large mixed-language software systems is of great importance to the Navy and beyond. Often the only reliable source of information about their architecture is the source code itself. Having a reliable way to automatically create visualizations of the architecture is… more
Abstract:The goal of this proposal is to advance the state-of-the-art in malware detectors, and thereby offer protection against next-generation malicious code. Currently, malware detectors - in the form of commercial virus scanners - are an important component in the defense of computer systems. We propose… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project will investigate a new approach to hardening programs against attack. The defense mechanism works by controlling how a process can interact with its environment, making it exceedingly difficult for an attacker to commandeer a system and… more
Abstract:Development of modern software applications involves the use (or reuse) of a large number of software components from many different developers - some of whom may be unknown, untrustworthy, or even hostile parties. A comprehensive approach is needed for identifying malicious and unauthorized code in… more
Abstract:We propose to develop a trace-based disassembler and integrate it with our break-through binary analysis tool, CodeSurfer/x86. A trace-based disassembler builds a trace of the instruction sequence that is executed at run time (during one or more runs of the program). The trace is analyzed to… more
Abstract:Malicious logic may be intentionally inserted into software as is the case with insider attack, or innocent mistakes may open vulnerabilities to worms and the like. We propose a double edged approach to inserting monitoring logic for machine code on all operating systems in order to ensure that:… more
Abstract:DESCRIPTION (provided by applicant):
Dose reduction for x-ray CT has taken on substantial importance with the increased use of this imaging modality and the imaging of younger patients. The objective of this work is to develop and demonstrate the technical and commercial feasibility of a novel… 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.
