HJ Science & Technology, Inc. proposes to demonstrate the feasibility of an integrated“lab-on-a-chip” technology capable of rapid and real time detection and identification of a variety of toxins in drinking water, particularly microcystins and other toxins produced by cyanobacteria. During blooms, the toxins in freshwater become concentrated enough to be a serious concern for ahuman health, ...

Environmental pollutants that impact critical biological pathways involved in human development and physiology can have unpredictable effect on health. Among these critical pathways, various receptor tyrosine kinases, sonic hedgehog, transforming growth factor beta, Notch and WNT are known or suspected mediators of the effect of numerous environmental toxicants produced during manufacturing, pres ...

The environmental impact of wood coatings has become a pressing issue as the manufacturing of wooden products such as flooring, cabinetry, furniture and doors is moving back to the United States amidst rising labor costs overseas. For the last thirty years the bulk of these products have been painted in countries with lax environmental regulations, allowing the use of inexpensive but environmenta ...

The proposed EPA SBIR Phase I program will create a novel ultra low power and low cost microfabricated CO2 sensor. The initial developments of sensor technology will serve the very large Demand Controlled Ventilation market that has been identified by KWJ and its collaborators. Phase I is dedicated to design, fabrication and testing of the innovative system consisting of a unique MEMS sensor, di ...

Breast cancer is not a disease of individual cells, but principally a failure of cells and tissues to communicate properly. One communication mechanism that is frequently disrupted in breast cancer involves the hormone estrogen. Despite recognition that exposure to compounds with estrogenic activity can promote breast cancer formation and progression, no good mechanistic explanation presently ex ...

Wastewater treatments minimize transmission of pathogens, and are required by the EPA with established treatment and monitoring requirements. The efficiency of treatment processes is determined by measuring the inactivation of indicator organisms (e.g., fecal coliforms) with culture-based techniques. Recently, Clostridium perfringens spores have been identified as excellent indicator organisms t ...

In this abstract the development of vertical power transistors utilizing bulk GaN substrates with breakdown voltages of 1200V or higher, normally-off operation, and a drain current rating of 100A is proposed. These devices will feature vertical current flow, avalanche ruggedness, and a wide operating temperature range (-55 to 150°C). The target specific on-resistance for the transistor is 30x low ...

Atmospheric aerosol plays an important role in climate and climate change, reduced visibility in urban areas, heterogeneous atmospheric reactions, and acid rain production. Fine aerosol from combustion sources is believed to be an important risk factor for cardiopulmonary disease and mortality. The Phase I objective is to examine the feasibility of producing an inexpensive, compact, robust laser-b ...

The oxo process is an important method of converting inexpensive olefins into valuable oxygenated building blocks. As a result, almost 10 million tons of oxo chemicals are synthesized annually worldwide. All oxo plants produce a reactor purge gas stream that contains 1-2 percent of the feedstocks entering the reactor. This purge gas usually is flared, and the residual feedstocks are lost. Membrane ...
