Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

Not Available This project is intended to develop a number of technologies and specific solutions to the problem of providing enhanced aircrew comfort particularly during extended missions and in ejection seats. This program will specifically address the issue of physical comfort associated with crew seating as opposed to the general cockpit environment. Efforts will be concentrated on the seat c ...

Not Available The purpose of the proposed research is to show that significant improvements in the performance of electrically tunable microwave devices can be obtained using a novel type of superlattice structures. The approach is based on recent work at Neocera showi

Not Available NASA SBIR Solicitation 98-1 emphasizes that ¿Advanced extravehicular activity (EVA) systems are necessary for the successful support of future human space missions.¿ Topic 09.05 recognizes that development of advanced EVA systems depends on ¿methods for..

Not Available Mod Works proposes to construct major airframe components using modern aluminum manufacturing process (MAM). The objective will be to reduce the cost of manufacturing while maintaining better surface quality. Major reduction in cost and labor requirement

Not Available There is rapid growth in the amount of remotely sensed (RS) image data. All future NASA and commercial remote sensing projects will have to deal with databases of unprecedent size and complexity. Providing an effective information link between these vast

This Phase I project is concerned with the development of a simple, cost-effective, environmentally friendly process for the production of potassium ferrate. Lynntech, Inc.'s proposed method can be readily scaled up for the production of industrial quantities of this extremely useful oxidant. Ferrate is an environmentally friendly oxidant that represents an ideal substitute for other oxidants, par ...

A novel, environmentally benign antimicrobial surface modification based on immobilized quaternary ammonium-functionalized dendrimers is proposed for the prevention of biofilm formation. Dendrimers are unique nanomaterials that have attracted attention as possible antimicrobial agents due to their compact structure, high local charge density of functional surface groups, unique carrier properties, ...

Chlorinated hydrocarbons represent the most prevalent contaminants in the subsurface, threatening the quality of groundwater at aquifers. Existing technologies for monitoring these contaminants require expensive, labor-intensive methods of sample collection and analysis. The goal of this Phase I research project is to develop a low-cost, compact, reliable, automated, unattended, and long-term mo ...
