Abstract:Formaldehyde (H2CO) has been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC) since 2004. Formaldehyde is the most important aldehyde produced commercially, and is used in the preparation of urea-formaldehyde and phenol-formaldehyde resins. One source of… more
Abstract:A recent breakthrough in combustion stability analysis (UCDS) offers the means to accurately predict the combustion stability of a scramjet. This capability is very important due to the extreme scramjet operational environment, which makes cut-and-try development approaches impractical. With UCDS,… more
Abstract:Building upon the successful use of the Universal Combustion Device Stability (UCDS) process to resolve NASAs Ares I thrust oscillation issue, the proposed effort will optimize UCDS for application to the oxygen-rich staged combustion (ORSC) cycle under development by the Air Force. This will be… more
Abstract:Applying multivariable optimization in conjunction with modern materials technology has revealed an opportunity to dramatically improve flywheel energy storage technology.

Abstract:To achieve the high propellant mass fraction (PMF) required by future high energy propulsion systems, light-weight propellant tanks are essential. GTL's Supra-tanksT can approach the theoretical performance limit for carbon fiber pressure vessels using cryogenic or room-temperature propellants. By… more
Abstract:This project will develop a prototype a federated search engine and web service for locating international science education research results based on supplied query terms. This prototype system will provide capabilities that will expand the functionality currently being developed for… more
Abstract:Government digital libraries ¿ such as the DOE¿s Office of Scientific and Technical Information¿s Information Bridge, Energy Citation Database, and other resources ¿ have a unique opportunity to facilitate communication between scientific communities of common interest. This project will add… more
Abstract:Today, a gap exists in reporting web metrics. Standard metrics tools do not have the ability to combine information about web resources with product-level details, such as the number of full-text downloads or specific user queries. This project will develop a prototype web metrics analysis system… more
Abstract:DESCRIPTION (provided by applicant): OptiPush Wheelchair Training System Wheelchair users are over twice as likely to be obese as people in the general population. The solution to obesity in the wheelchair user population is the same as it is in the gener
al population, a healthy diet and regular… more
Abstract:This Small Business Innovation Research Phase I project will result in a suite of microbial source tracking assays to provide cost-effective identification of fecal contamination sources in surface waters. Beach closures and advisories exceeded 20,000 days in each of the past 3 years with more than… more
Abstract:The efficiency of the conventional fossil-power plant can be improved by increasing the steam temperature and pressure. The DOE is targeting an increase of the steam temperature from 593°C to 677°C by the year 2010 and to 760°C by 2020. Currently, ferritic steels are used at temperatures below… more
Abstract:Electronic waste (e-waste) is one of the most rapidly growing waste problems worldwide. Improper handling of e-waste results in vast amounts of toxic waste being sent to landfill and leaching into the water supply. Due to there concerns e-waste recycling is a rapidly growing industry. … more
Abstract:This Small Business Innovation Research Phase I submission proposes to design and produce nanofiber-based corneal tissue scaffolds to treat corneal diseases, the second most common cause of blindness worldwide, affecting 10-15 million people. This innovative approach uses electrospun mats from… more
Abstract:The semiconductor electrodes on segmented germanium planar detectors used in nuclear physics research require improvement, so that significantly more of the available high-purity germanium can be utilized for the detection function. This project will develop new semiconductor electrode technology… more
Abstract:The next generation of DOE low-background user facilities will require suitable germanium crystal production capabilities. These crystal-growth techniques must accommodate the handling of highly enriched germanium in a manner consistent with low background counting. In this project, germanium… more
Abstract:This project involves development of a non-destructive, non-invasive technique for visualization and characterization of root damage by devastating root pests using digital x-ray imaging.

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.
