A compact and affordable, microchip-based system for the automated, in situ analysis of inorganic ions in atmospheric aerosols will be develop and verified against traditional, filter-based methods. Our approach combines tow new technologies: (1) a growth tube impactor for particle collection and (2) lab-on-a-chip (LOC) analysis of sulfates and nitrates. The growth tube impactor enlarges indivi ...

Conventional cement based construction materials such as stucco and concrete are prone to cracking with poor thermal insulation, and are very permeable to water. Repair of deteriorated cement based structures is a major problem, and in United States alone repair cost is estimated to be over $100 billion range. Commercial stuccos are susceptible to cracking under the influenced of repeated fluctu ...

A compact and affordable microchip-based system for the automated, in situ analysis of inorganic ions in atmospheric aerosols will be develop and verified against traditional, filter-based methods. Aerosol Dynamics, Inc., will combine two new technologies: (1) a growth tube impactor for particle collection, and (2) lab-on-a-chip (LOC) analysis of sulfates and nitrates. The growth ...

In the 2002 Small Business Innovation Research Solicitation, the U.S. Environmental Protection Agency explicitly expressed interest in instruments that can accurately and reliably measure particulate emissions from vehicles. The availability of suitable instruments for measuring particulate emissions from engines and vehicles will benefit two broad categories of users: (1) it will directly help ...

In 1991, the U.S. Secretary of Health and Human Services called lead ¿the number one environmental threat to the health of children in the United States.¿ Lead exposure can cause premature birth and impair a child¿s mental and physical development. In adults, lead exposure can cause kidney damage, high blood pressure, and other problems. The U.S. Environmental Protection Agency estimates tha ...

This Phase II project addresses the development of technology that would provide field-based quantitative detection of a wide range of environmental contaminants through the use of molecularly imprinted polymers and fluorescence detection. The proposed method would complement immunological methods of analysis that have been adapted to contaminants such as herbicides and pesticides. The well-docume ...
