NAI has a strategy to identify plant species best suited for proof-of-concept testing for phytoremediation of perfluoroalkyl substances (PFAS) via phytoextraction. Phytoextraction refers to the uptake and translocation of contaminants in the soil by plant roots into the aboveground portions of plants. Once the phytoextraction concepts are proven at the bench-scale (Phase I) and followed with succe ...

The goal of this project is the formulation a rigid, insulating, low-density wood composite, with physical and thermal properties comparable to fossil fuel derived foams. _x000D_ _x000D_ To achieve energy conservation standards mandated by certification agencies such as Passive House and LEED, high performance buildings require multiple shells of insulation – an inner shell that contains electri ...

The objective of this project is to design a software architecture based on densely-connected neural network to perform automatic targetsegmentation and recognition using training datasets of limited size (low-shot). Deep learning architectures have proved to be extremelyeffective at object detection and recognition, but such capability comes at the cost of having large labeled datasets. Such data ...

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 ...

A1-CHEM FUELS, INC. HAS A PATENT PENDING FOR AN ELECTROTHER-MAL DEVICE TO PRODUCE MEDIUM TO HIGH BTU FUEL GAS FROM WASTEHYDROCARBON SOURCES. THIS UNIT OPERATES BY PRODUCING A HIGH-VOLTAGE ALTERNATING CURRENT ELECTRIC DISCHARGE ACROSS THE INTERFACE BETWEEN A WASTE HYDROCARBON AND WATER. THE EXTREMELY HIGH TEMPERATURE WITHIN THE ELECTRICAL DISCHARGE IS SUFFICIENT TO CAUSE LOCALIZED FAST PYROLYSIS OF ...

BACTERIA INDUCE MANY OF THE PROBLEMS ASSOCIATED WITH PUBLIC PROBLEMS ASSOCIATED WITH WATER BORNE PATHOGENS. IN ADDITIONTASTE, ODOR, COLOR AND TURBIDITY PROBLEMS ARE SOMETIMES CAUSED BY BACTERIAL, FOULING AND CORROSION ARE ALSO CAUSED BY BACTERIA. FOULED WATER SYSTEM COMPONENTS PROMOTE DEVELOPMENT OF PROTECTED OR SHIELDED CONSORTIA OF BACTERIA WHICH DECREASES THE EFFGECTIVENESS OF CHLORINE (OR OTHE ...

CONTAMINATION OF GROUNDWATER BY TRICHLOROETHYLENE AND OTHER VOLATILE HALOGENATED SOLVENTS REPRESENTS A SERIOUS THREAT TO THE NATION'S DRINKING WATER. CURRENT TREATMENT TECHNIQUES FOR CONTROLLING SUCH CONTAMINATION ARE LIMITED TO AERATION, ADSORPTION, AND LINKING. A PROMISING ALTERNATIVE IS PHOTOCHEMICAL OXIDATION, BUT THIS PROCESS IS AS YET UNOPTIMIZED, POORLY UNDERSTOOD, AND LARGELY LIMITED. PHOT ...
