This Phase I research is intended to evaluate the feasibility of manufacturing low-cost, acid-resistant sanitary sewer pipe from sulfur concrete. Sulfur is an abundant mineral recovered from coking, natural gas processing, and petroleum refining. Secondary recovery of sulfur, resulting from environmental regulation, produces more material than is needed by U.S. industry. The U.S. Bureau of Mines ...

Infrared tunable diode laser spectrometers provide a highly effective means of measuring trace concentrations, with either remote sensing or with advective sampling. It is often desirable to measure more than one trace gas at a time. This is especially true when gas emissions are strongly correlated, such as in combustion emissions where measuring both the CO2 concentration and another minor con ...

This Phase I project will develop a multianalyte biosensor field screening instrument (MBFI). The MBFI has the potential to reduce the annual cost of environmental analyses in the United States by more than $20 million and to reduce the analysis turnaround time from approximately 19 days to less than 15 minutes. The major barrier to the development of a biosensor instrument for environmental mea ...

Laser-induced fluorescence (LIF) can sometimes be used as a diagnostic device in biology and medicine. In general, LIF has difficulties in relating the fluorescence spectra to the concentration of the emitters within the tissue, in identifying different species, and in the possibility of destroying the molecules being probed if the wrong excitation wavelength is chosen. Many of the problems asso ...

Zebra mussels cause an estimated $5 billion in economic damages annually. They clog water intake pipes, damage water supplies, threaten native fish and aquatic species, and promote the mobilization of toxic materials into the food chain. Chlorination is presently the most common treatment for zebra mussels. However, chlorine causes many serious environmental risks, thus necessitating the develo ...
