Ballast water discharge may contaminate receiving waters, creating an extremely pervasive problem in which control/mitigation after introduction is very expensive. Thus, prevention is paramount. This project will develop an automated, modular, pilot-scale add-on ballast treatment system based on the electrocatalytic onsite H2O2 solution generation technology demonstrated in Phase I. Phase II effor ...

This project will utilize photolithography and microfabrication in the assembly of a Cr(VI) monitoring device that is compact, portable, and cost effective. The proposed sensor will be a self-contained laboratory that samples, analyzes, and stores the results of onsite testing under a variety of sampling conditions. The device will rely on the pressure-driven introduction of aqueous samples that w ...

The objective of this project is to develop advanced heterogeneous catalysts for catalytic wet air oxidation (CWAO) of volatile or toxic organic compounds present in industrial wastewater. Inclusion of catalysts in wet air oxidation systems increases complete destruction of organic compounds and reduces the severity of the operation conditions, resulting in a substantial decrease in processing cos ...

"Under this proposal we will develop, test, and document new methodologies for creating probability density functions (PDFs)of first-arriving and secondary seismic phases from datasets of seismic phase arrival times and hypocenters. Algorithms will bedeveloped to use seismic phase PDFs in standard earthquake location procedures in the context of phase association and weighting. Tests will be condu ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

"Nuclear Weapons Effects Tests (NWET) frequently require that the test article be irradiated in an ultra-clean environment, making survivable shields a necessary part of many debris systems. Survivable shields as large as 12 inches in diameter are requiredbut have yet to be demonstrated in Plasma Radiating Source (PRS) environments. The loads on a survivable shield are a combination of radiation i ...

"Measurements of fluence from a Plasma Radiation Source (PRS) are critical to the performance of accurate Nuclear Weapon Effects (NWE) experiments. Fast, total stopping calorimeters have been demonstrated to provide a robust, reusable, economic sensor forfluence measurements. However, the output of these sensors is a few millivolts and thus high signal to noise recording is difficult to achieve, ...

Recent studies have shown that certain fluorosurfactants are toxic to aquatic life and tend to accumulate in the blood of animals and humans because they are persistent chemicals. As a consequence of this discovery, 3M decided to phase out some of their fluorosurfactants in May 2000. Among the phased-out products are 44 fire-fighting foams and foam components. At the present time, there is no repl ...
