Abstract:Parenteral vaccines have many limitations which pose problems for both military and civilian vaccination programs. Parenteral vaccines must be administered by trained personnel, a booster is generally required for maximum protection, they usually contain a single immunogen and require refrigeration… more
Abstract:Fuel cells bring about the direct conversion of stored chemical energy to electrical energy having efficiencies much higher than those of Carnot engines. So far, the proton exchange membrane (PEM) fuel cell system is the leading candidate fuel cell power source for many military and commercial… more
Abstract:Semiconductor-catalyzed photooxidation of chemical waste is a comparatively recent development which offers several advantages over other know oxidation processes. The advantages include: 9i) no consumption of expensive oxidant; (ii) catalyst is non- hazardous; (iii) the photocatalytic reactions… more
Abstract:The purpose of this Phase I project is to demonstrate a feasibility of using room-temperature, air and water stable molten salts to fabricate advanced non-lithium batteries as compact, high power, quick reacting, long term inert storable energy sources for use in military weapons or missile targets.… more
Abstract:The structures of aircraft onen suffer from corrosion especially in humid, hot, polluted areas, and near to marine environnents. CoiTosion nay shorten the aircraft's sevice life, increase naintenance and repair costs, and even cause structural failures. Therefore, there is a critical need to develop… more
Abstract:No one questions the philosophy that it is better to avoid industrial pollutionrather than to attempt the clean up of an environmentally abused site.Unfortunately, we are slow to learn this lesson and hazardous wastes become moreexotic and continue to increase. Causing 21 of the 28 EPA superfund… more
Abstract:Treating waste sites contaminated with dioxin is both costly and difficult. Current clean up standards require that treatment reduce dioxin residuals to very low levels. The allowable level of residuals is very strict because of the assessment that dioxin poses a serious health hazard. At present,… more
Abstract:Insulated gate bipolar transistors (IGBT) represent the standard component in converters for electric vehicles and motor control. However, they are a mature technology where only marginal performance improvements can be expected, and improvements in IGBT based converter efficiency can only reflect… more
Abstract:Industrial wastewater containing toxic waste compound and metal ions pose manyproblems of disposal. The most generally used method of removing metalcontaminants is lime treatment to precipitate metals as hydroxides. The metalis not normally recovered resulting in the need for sludge disposal. The… more
Abstract:Todays thermoelectric cooling materials exhibit a peak performance, termed ZT, of about 1.0. Recent development in the theory of quantum-well superlattices suggest that ZTs of up to 9 are possible. Work is ongoing to synthesize superlattices using techniques such as molecular beam epitaxy,… more
Abstract:Bismuth rich BiSb alloys exhibit the best n-type thermoelectric properties known. However, these properties are realized only in single crystals which are difficult to machine because they tend to cleave. Also, the anisotropic nature of BiSb requires that that the device current be passed across… 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.
