Engineered Vesicles for Perchlorate Degradation
… the use of engineered vesicles to reduce perchlorate. Specifically, cell-free extracts containing perchlorate reductase and chlorite dismutase enzymes were encapsulated in a triblock copolymer vesicle functionalized with the outer membrane porin OmpF. The porin allows for perchlorate …

Weakening of ice by magnesium perchlorate hydrate
I show that perchlorate hydrates, which have been indirectly detected at high Martian circumpolar latitudes by the Phoenix Mars Lander, have a dramatic effect upon the rheological behavior of polycrystalline water ice under conditions applicable to the north polar layered deposits (NPLD). I …

Investigation on Ammonium Perchlorate Based Electrically Controlled Propellants
… polymer (polyethylene glycol) and ammonium perchlorate (AP) was conducted. Complexation of AP with PEG enabled ion transport when a voltage was applied resulting in ignition. Although the propellant was manufactures by solution casting, the final product contained no solvent as confirmed by …

The removal of perchlorate from waters using ion-exchange resins
… several types of ion-exchange resins to remove perchlorate from waters. The capability of the resins to remove perchlorate, as well as their regeneration efficiency, were evaluated using both synthetic solutions and perchlorate-contaminated water from the Las Vegas Valley. For synthetic …

Abiotic and Biotic Perchlorate Removal in an Activated Carbon Filter
… research has demonstrated that, while abiotic perchlorate removal by GAC is ineffective, BAC filtration can provide efficient, sustained perchlorate removal under a broad range of operating conditions and water quality characteristics.

Low flux radiative ignition studies of ammonium perchlorate composite propellants
The vast majority of propellant ignition data has been collected and studied for heat fluxes in the typical, intentional ignition range. However, when a propellant contained within a rocket motor case is exposed to low fluxes in hazardous situations, such as close proximity to a fire, unwanted …

Kinetics and stoichiometry of the aquation reaction of pentaaquomonobromomethylchromium (III) perchlorate
The purpose of this thesis was to determine the kinetics and stoichiometry for the aquation of the pentaaquomonobromonmethylchromium(III) complex. The complex was prepared by the reduction of dibromomethane by chromium(II). The products of aquation, in the absence of oxygen, were found to be …

Transport of perchlorate in the Las Vegas Wash and Lake Mead
This thesis investigates the fate of perchlorate in the Las Vegas Wash and Lake Mead resulting from the long-term contamination by the manufacturing of rocket fuels in Henderson, Nevada. The changes in perchlorate concentrations for the Las Vegas Wash and Lake Mead were investigated for the last 10 …

Evaluation of in situ biodegradation of perchlorate in a contaminated site
This thesis investigated parameters affecting perchlorate biodegradation in the Las Vegas Wash area in Las Vegas, NV. Perchlorate is known to interfere with the functioning of the thyroid gland of humans. Perchlorate concentrations along the Las Vegas Wash were found to range from zero to 1000 ppb, …

The removal of perchlorate from waters by a membrane-immobilized biofilm
… a membrane-immobilized biofilm reactor to remove perchlorate from waters. Perchlorate (ClO4 -) is easily reduced under anaerobic conditions to harmless chloride (Cl-). In this system, the perchlorate-contaminated water is physically separated from the biofilm by the membrane. Perchlorate diffuses, …

Catalytic Role of Boron Nitride in the Thermal Decomposition of Ammonium Perchlorate
The decomposition of Ammonium Perchlorate (AP), a strong oxidizer used in solid rocket propellant, is widely studied in an attempt to increase the burn characteristics of propellants. Many materials have been shown to catalyze its decomposition, but little is known about the mechanism by which AP …

Microbial Reduction of Perchlorate in Fixed Bed Biofilm Reactors for Water Treatment
… reduce oxygen's negative effect on biological perchlorate removal was discussed. Chemisorption of oxygen onto GAC was found to enhance the performance of BAC under sudden increases in influent DO. A mathematical biofilm model describing the competition between PRB and other heterotrophic …
