Abstract:A novel urine pretreatment that will prevent biological growth or chemical instabilities in urine without using hazardous chemicals is proposed. Untreated urine fosters biological growth, ammonia generation, creation of bio-solids, and inorganic precipitates, which foul water… more
Abstract:DESCRIPTION (provided by applicant): This project will determine the performance and operating specifications for a low-cost optical ammonia sensor for medical applications. Ammonia in human breath has been established as a significant biomarker with high… more
Abstract:… gas (NCG) inside the reservoir. At low power, most of the condenser is blocked by the NCG. As the power increases, more and more of the condenser becomes active. This allows a VCHP to passively control the temperature while the power varies. Aluminum/ammonia VCHPs are… more
Abstract:… an economical means for industrial facilities to achieve stringent dioxin-furan emission limitations. Air Control Techniques, P.C believes that photochemical treatment for dioxin-furans will simultaneously reduce emissions of other contaminants such as formaldehyde and … more
Abstract:… is currently not economically favorable, primarily because of the high costs of building and operating the complex systems required for nitrogenous waste removal (biofiltration). We propose to develop and test a simple and efficient device that converts ammonia in water… more
Abstract:"The National Research Council has concluded that ammonia is a major concern for
air quality at global, national and regional scales. In the US, livestock operations are
believed to contribute over 80% of the total emissions of ammonia. Specific interest in
ammonia emissions… more
Abstract:This Phase II program will produce a sensitive, reliable and cost-effective monitor for ammonia
emissions in confined animal feeding operations (CAFOs). CAFOs have become a major form
of animal production. There is increased concern over emissions from confinements houses… more

Abstract:… (>7000 hours), low cost (100W system under $1000), instant startup (less than 2 seconds), start/stop resilience (>7000 start/stops), and a wide environmental temperature (-20 to 55 degrees C). Jadoo has already developed standardized fuel canisters that use ammonia… more
Abstract:… limiting cloud production and reducing precipitation. Also, sulfate aerosols in the stratosphere reflect sunlight, moderating climate warming. In laboratory experiments, sulfate aerosol formation appears to depend in a strong and non-linear manner on ammonia… more
Abstract:… to develop a lightweight, compact, rugged, near and mid-infrared gas-sensing spectroscopy instrument to accurately measure the abundance of various gases on Mars and other extra-terrestrial bodies. These gases include methane, water vapor, carbon dioxide, and ammonia. This… 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.
