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
Abstract:…. Both Chlorine and Iodine are extremely caustic substances and require great care when handling. Of particular importance is the lifetime of high performance valves used to meter these substances as well as all other ABL fluid products (Helium, Nitrogen, ammonia and… more
Abstract:… voltage, possibly reducing it from tens of volts to few volts with faster switching times. Also, environmentally hazardous mercury droplet is replaced by non-toxic gallium alloy. Since gallium alloy is easy to oxidized, use of separation of oxide liquid/gas such as ammonia… more
Abstract:…roach incorporates a novel system design for selective photoionization for electrophoresis of selected gases, for electrophoretic processing, to meet the NASA requirement for equipment with low launch mass to separate hydrogen, carbon dioxide, nitrogen, helium, water, ammonia,… more
Abstract:In this Phase I program teaming with system integrator, Powdermet will develop a low cost light weight, high strength, chlorine, iodine, helium, ammonia, caustic compatible corrosion resistant, high performance, long life capable, maintenance free Self- Lapping Chemical Valves… more
Abstract:Toxic industrial chemicals (TICS) include widespread substances, such as ammonia, chlorine, and hydrogen cyanide. In order to help DOD with its efforts to detect TICS in military operations, Sensorcon is proposing to integrate carbon nanotubes (CNT) into its micro… more
Abstract:The effects of aerosol particles on climate are the most uncertain aspects for quantifying the impact of human activities on future climate changes. Although ammonia plays a critical role in the formation and identity of atmospheric aerosol particles, ammonia is incredibly… more
Abstract:… propulsion systems. N2O can replace both hot-gas propellants such as hydrazine and cold-gas ACS systems such as nitrogen or isobutane. N2O is non-toxic, has a low freezing point (-91oC), and stores as a liquid. N2O is also a byproduct of the catalysis of … more
Abstract:Emission of ammonia to the atmosphere is a major environmental concern and a potential health hazard, but the accurate measurement of ammonia sources requires improved instrumentation. There is an immediate need for such instrumentation for both monitoring and research in… more
Abstract:… spatial and temporal variability in agricultural, environmental, and climatic conditions, and will be implemented within a user interface on the internet. NUGGET will assist users in developing management strategies that minimizing nutrient and pesticide leaching, ammonia… more
Abstract:The Department of Energy (DOE) has 280 underground tanks used to process and store over 90 million gallons of high-level radioactive chemical waste. The conditions in the tanks are conducive to the formation of flammable gases such as hydrogen, ammonia, and methane, as well as… more
Abstract:… noise and enables the use of very small gas cells (< 1cm3), which facilitates the development of portable and sensitive trace gas point sensors. The objective of the Phase I project is to develop and test a prototype QEPAS sensor for sensitive measurement of atmospheric ammonia… 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.
