Abstract:We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead… more
Abstract:Extracorporeal life support (ECLS) is used for newborn infants with respiratory failure. Improvedlong term ECLS efficiency is desirable and would allow broader (children/adults/ cardiac support) andsafer use. Systems are based on microporous (hollow fiber) membranes or silicon non-porousmembranes.… more

Advanced neutron-based sensors are required in support of treaties to enforce international non-proliferation and national security goals pertaining to weapons of mass destruction. Reliable, long-life sources… more
Abstract:Success in aquaculture depends heavily on delivery of oxygen to fish. Currently, liquid oxygen and on-site generation by pressure swing adsorption (PSA) are two methods for supplying oxygen to aquaculture. Both are costly and have absorption efficiency problems. Membrane contractors, paddle… more
Abstract:Disinfection is a critical process step in potable water treatment. Chlorine is currently the most widely used, and least costly disinfectant. An unfortunate by-product of chlorine disinfection is the formation of carcinogenic trihalomethanes (THMs) when chlorine reacts with organics dissolved in… more
Abstract:Osteoporosis is a major worldwide public health problem with over 20 million individuals affected in the united states. Over 1.5 million fractures occur in the united states annually, resulting in 750,000 visits to the physician and long term hospitalization with a total impact to the health care… more
Abstract:Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water,… more
Abstract:Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean… more

Abstract:We propose a new epitaxial growth technology for low-defect SiC substrates based on metallic solution growth of SiC on silicon and SiC wafers. A significant feature of the our approach is the use of epitaxial lateral overgrowth for "defect filtering." In the Phase I proposal, we present arguments… more
Abstract:There is much need for lasers with emission wavelengths in the mid-infrared (2 to 5 microns) for applications that include molecular spectroscopy, environmental and atmospheric trace gas analysis, long haul fiber communications, laser surgery, and atmospheric free-space laser transmission. The… more
Abstract:AstroPower proposes to develop a new high voltage solar cell for photovoltaic linear concentrator arrays based on our thin GaAs solar cell and epitaxial lateral overgrowth technologies and applying lateral segment interconnection techniques. This solar cell design has several advantages which make… more
Abstract:Many lung disorder patients (cystic fibrosis, COPD) require supplemental oxygen. Studies showboth quality and length of life improves if these patients maintain active mobile lives. Their mobility islimited, since many need to stay near their supplemental oxygen source. Portable oxygen enriching… 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.
