Chlorinated hydrocarbons represent the most prevalent contaminants in the subsurface, threatening the quality of groundwater at aquifers. Existing technologies for monitoring these contaminants require expensive, labor-intensive methods of sample collection and analysis. The goal of this Phase I research project is to develop a low-cost, compact, reliable, automated, unattended, and long-term mo ...

Some bioterrorism agents cause disease at very low infective doses and their presence can be masked by the environment. Therefore, ultrasensitive detection is required for homeland defense applications. In this Phase I research project, Operational Technologies Corporation (OpTech) proposes to couple DNA aptamers made by the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) proce ...

The design, construction and feasibility testing of X-ray fluorescence (XRF) based instrumentation capable of detecting the presence of atomic species within ambient particulate mater (PM) on near real time basis has been successful completed. The XRF analysis is made feasible for hourly ambient PM samples through the implementation of novel high volume flow impaction and post-impaction concentra ...

The goal of this Phase I research project is to develop a prototype instrument capable of performing specialized elemental speciation of ambient particulate matter (PM) in near real time (1-hour batch collection/analyses). The prototype monitor will incorporate high-volume impaction and x-ray fluorescence technology to accomplish the stated task. Through previous research, Rupprecht & ...

The Phase I study resulted in the development of an assay that tests substances that have the capacity to disturb reproductive and developmental processes during the lifecycle of a vertebrate animal by interfering with the endocrine system. The primary goal of this Phase II research project is to standardize, validate, and commercialize an amphibian lifecycle model using Xenopus as a ...

Perfluoroalkyl substances (PFASs) have received considerable attention due to their toxicity, ubiquitous presence and recalcitrance. Manufacture and disposal of PFAS-containing products has resulted in PFAS contamination of numerous water supplies. Recent reports indicate the Air Force alone is expecting to spend > $2.25 billion for cleanup for PFAS-contaminated sites. Thus, there is a huge market ...

The presence of per- and polyfluoroalkyl substances (PFAS) in the environment represents an emerging issue due to their stability, bioaccumulation potential, and risks to human and ecological well-being. There is a critical need to develop sampling methods for PFAS to assess risks and inform remedial investigations and feasibility studies (RI/FS) at locations where historical releases have elevate ...

This green approach to manufacturing plastic with decorative chrome will eliminate health and environmental hazards from the chrome electroplating process. The US and global market for decorative chrome on plastic is 12 million m2/year and 84 million m2/year respectively, with 80% in automobile trim, 10% in appliances and 10% in sanitary fixtures. Without a viable commercial alternative, US provid ...
