Research & Education
Recovery of nutrients from inedible plant material (Life Support Systems for Space Travel, NASA): Determination of the biodegradation rates and waste treatment requirements of the inedible part of the biomass (stem and leaves). Waste treatment is part of a life support system where materials are continuously recycled and re-used. Total recycle of materials is extremely important for extended space travel and planet missions (e.g. a mission to Mars) where supplies cannot be routinely transported from the earth
Greywater treatment in Gravity Independent Bioreactors: Development of a fixed bed bioreactor for the treatment of wastewater under microgravity conditions. The system operates under pressure to deliver oxygen to attached microbial consortia which metabolize the organic molecules in the waste
Investigation of Fate, Transport, Biodegradation and Potential Toxicity of hexanitrohexaazaisowurtzitane (CL-20) in Environmental Systems: Evaluation of the mobility of neat CL-20 in the Environment (soil, groundwater, air interactions), study of its bioavailability and degradation (both biotic and abiotic), and toxicity assessement. Assessment of Thorium Migration at a Training Site at Kirtland Air Force Base: A study of the fate and transport of Thorium (232Th) at a contaminated site at Kirtland Air Force Base in Albuquerque New Mexico. Specific containment technologies are investigated for their potential to reduce migration of the thorium -laden soil off site and vertically. In addition, remediation technologies such as soil washing and electro-kinetics are investigated. Investigation of Fate, Transport and Toxicity of Tungsten Alloys and Molybdenum Utilized in Munition Applications in Soil Environments: Evaluation of the rate of release and mobility of tungsten alloy components from projectile fragments and grains in the subsurface environment (soil, groundwater interactions), study their bioavailability and assess their toxicity
Investigation of RDX and PAX-21 Propellant Treatment Methods: Cost analysis of treatment processes for the decontamination of RDX contaminated groundwater, and investigation of the biodegradability of the post hydrolysis products of groundwater treated with hydroxide solutions. Alkaline hydrolysis of PAX-21 propellant in batch reactors. Development of Large Volume, Ambient Pressure, Non Thermal Diffuse Plasma Reactor for Destruction of Airborn Environmental Contaminants in Advanced Life Support Systems: An investigation on the effectiveness and efficiency of a novel, non-thermal diffuse plasma technology for the destruction of environmental air contaminants in space applications. The plasma characteristics, plasma chemistry, contaminant destruction efficiency and reaction kinetics for various compounds expected to be present in advance life support environments are studied
Monitoring of PCBs and other Semivolatile Organic Compound Air Emissions in Sites Receiving Stabilized Harbor Sediment: Development and implementation of a field monitoring program to investigate the potential volatilization of SVOCs, including PCBs, at two sites in New Jersey where placement and compaction of sediment from the NY/NJ Harbor region is taking place
Toxics Monitoring in the New York/New Jersey Harbor: Sampling and analysis of the water column at various locations in the rivers and tributaries flowing into the NY/NJ harbor. This includes identification of pollutant sources upstream, and fate and transport of organic contaminants and heavy metals into the water colun and the harbor
Investigation of a Novel Capillary Non-Thermal, Ambient Pressure Plasma for Cleaning of Aluminum Surfaces: Development of a non-thermal diffuse plasma technology for the cleaning and decontamination of aluminum surfaces. Experiments are being conducted to determine the plasma characteristics necessary for the destruction of organic substances deposited on aluminum surface, to identify the proper plasma gases for effective removal, to determine the role of the surface on destruction efficiency, and to evaluate surface changes due to plasma irradiation
Use of Capillary Non-Thermal, Ambient Pressure Plasma in Decontamination of Water Recovered from Vehicle Exhaust: Investigate the potential role of diffused non-thermal plasma in the treatment of water condensate recovered from the exhaust of the diesel engines of Hum-Vee and other vehicles. One treatment scenario involves pre-treatment of the combustion mixture in order to increase the efficiency of combustion and thus reduce the concentration of undesirable organic products in the diesel exhaust gases. The second treatment scheme focuses on plasma treatment of the exhaust gases prior to condensation. Finally, a treatment system is investigated which treats the aqueous solution obtained from the condenser by continuously passing the vapors produced from the liquid phase through a plasma reactor in a closed loop configuration
