"This SBIR Phase I project will develop an affordable, sensitive, fast-response solution to real-time monitoring of Elemental Carbon (EC). EcoChem will employ a proven sensor technology, the photoemission aerosol sensor (PAS) to detect EC. The PAS photoionizes carbonaceous aerosols with a unique excimer lamp [Burtscher, 1992] whose wavelength is chosen to selectively ionize EX and polycyclic aro ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

Outdoor wood-fired boilers (OWB) are gaining in popularity for heating homes. As energy prices have risen, sales of OWBs are doubling each year because they provide a lower cost solution and use renewable fuel. There is concern about their air emissions, however. OWBs typically emit 18 times the pollution of an EPA certified wood stove and there are currently no emission controls for OWBs. The ...

"Operational Technology Corporation (OpTech) proposes to couple the ultrasensitivity of fluorescence-based detection with the high selectivity of synthetic DNA aptamers as replacements for antibodies to detect chemical and biological (CB) terrorism threats in 10 minutes or less from a variety of swabbed surfaces and liquid matrices. OpTech has previously provided strong proof-of-concept for a rap ...

Inorganic color pigments based on hazardous metals such as chromium, mercury, cobalt, lead, etc., account for more than 95% of the U.S. and worldwide pigments consumption. Color pigments are commonly used by numerous industries and in various consumer products. It is estimated that they are one of the largest vehicles of heavy metal-based chemicals in commerce. A technology that can provide a co ...

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 ...
