In 2001 the US EPA lowered the maximum contaminant level for arsenic in drinking water from 50 ppb to 10 ppb. This change is expected to impact 10 percent of the nation's drinking water systems; the vast majority of those impacted are small, rural water suppliers. New approaches, particularly simple, adsorption-based technologies are needed to provide cost effective treatment options for small wat ...

72679-Radioactively contaminated surfaces within Department of Energy and commercial nuclear facilities endanger workers and create problems with waste handling and disposal. Current methods for removing these radiological contaminants are expensive, use hazardous chemicals or dangerous rotating machinery, release removed materials into the airspace surrounding the jobsite, and generate considera ...

72275-With the ever-present threat of terrorist attacks on American soil, it is increasingly important to monitor pre-nuclear-event warning signs and provide post-nuclear-event assessment for use in consequent management and emergency response. In particular, major urban centers are potential targets of nuclear attacks, ¿dirty bomb¿ attacks, and chemical/biological agent attacks. This project ...

The release of mercury into the environment via combustion processes has become an issue of concern for the US and the entire world. Major sources either are regulated or are under review to develop regulations to reduce emissions. ADA Technologies has successfully demonstrated the performance of a novel reactive scrubbing technology for the removal of vapor-phase mercury from incinerator exhaus ...

75570-Coal gasification is a promising technology for reducing U.S. dependence on foreign energy sources. However, the development of efficient and cost effective pollution control technologies will be required before coal gasification can be introduced on a commercial scale. In particular, the removal of sulfur species and trace metals (mercury, arsenic, and selenium) presents a technical and e ...

72212-The uniform dispersion of nanoceramic filler particles within a polymer matrix, for producing high quality polymer/ceramic nanocomposites, is a very time-and energy-intensive process. The development of efficient methods for uniformly dispersing nanoceramic inclusions, which are well-adhered to the polymer throughout the polymer matrix, and for fabricating parts from such composites at low ...

A critical military requirement exists for a fast, cost-effective, six-degrees-of-freedom (6DOF) technology that can track a pilot's helmet though rear-projection screens and is immune to distortion and interference from scatterers of magnetic/electrical energy. Building upon Phase I research that demonstrated feasibility of projecting light energy through graphics projection screens, Ascension T ...

The malicious distribution of Bacillus anthracis spores through the U.S. Postal Service in the fall of 2001 demonstrated the vulnerability of the United States to biological threats. These events showed the need for improved decontamination methods for buildings and assets exposed to various biological agents, because the current methods rely on the application of a chlorine- or formaldehyde-base ...

Diverse mission requirements and advanced capabilities from defense spacecraft are placing demands on power subsystems beyond that which can be delivered by current state of the art solar arrays. Although cell level specific power has increased, similar advancement is necessary in the deployment system to take full advantage of future high power arrays. State of the practice systems have specifi ...

76206-Heat is generated and used in many industrial processes. Although, the remaining low-temperature heat from these processes is typically dispersed to the atmosphere, this waste heat could be utilized to produce electric power for on- or off-grid use. This project addresses this need through the development of an Organic Rankine Cycle engine that utilizes a hermetic seal-less approach for co ...
