Structural effects of intrinsic and extrinsic perturbations to model membranes

Creator:: Church, Sara E.
Abstract:: The observed and calculated structural parameters of three systems of phosphatidylcholine bilayers in fully-hydrated multilamellar vesicles (MLVs) were determined using x-ray diffraction techniques. The analysis used the x-ray reflections from the low-, intermediateand wide-angle regions of the diffraction patterns in the subgel, gel, rippled and fluid phases to determine the...

The infrared and far-infrared spectra of sublimed films of formaldehyde

Creator:: Held, Andrew Mackie
Abstract:: The infrared spectra of liquid and solid films of formaldehyde were taken over the range of 35 to 4,000 cm⁻¹ using Beckman IR 7 and IR 11 spectrometers. A new overtone band and a new combination band were found as well as three fundamental peaks due to lattice vibrations and...

The role of iron-oxides in U(VI) adsorption and the kinetics of contaminant organic reduction

Creator:: Logue, Brian A.
Abstract:: Contaminant transport in ground water is an important environmental process that affects a host of natural systems. Transport of contaminants is affected by many processes, including aqueous complexation, adsorption, and redox reactions. One of the most important components of an aquifer that controls transport is iron-oxide. In this study, the...

A study of the oxide/solution interface by capacitance measurements of electrolyte/oxide/semiconductor structures and potentiometric titrations of colloidal oxide suspensions

Creator:: Hindagolla, Suraj L.
Abstract:: The oxide/electrolyte solution interface has been studied experimentally by two methods, and a mathematical model for the interface has been developed. The change in interfacial potential with solution composition was determined through the capacitance of electrolyte/oxide/semiconductor (EOS) structures and the charge through potentiometric titrations of colloidal oxide suspensions. The differential...

The distribution of organic bases in reverse phase liquid chromatography : a study of mechanisms

Creator:: Jayasinghe, Dudley Shelton
Abstract:: The distribution of hydrophobic ionogenic organic compounds (HIOC's) between aqueous and nonaqueous phases has been investigated. The HIOC's are aniline and methyl substituted anilines. The aqueous phases are methanol-water mixed solvents with varying pH and ionic strength. The nonaqueous phases are silica and alkyl derivatized silica with ethyl- (C-2), octyl-...

Development and application of an analytical technique for the determination of methylmercury compounds in environmental samples based on isolation by distillation, followed by purge-and-trap sample concentration and GC/MS separation and detection, after aqueous phase ethylation with sodium tetraethylborate

Creator:: Rice, William R.
Abstract:: An analytical technique has been developed for the determination of methylmercury compounds in environmental samples. The technique is based on a two-stage procedure. In the first stage, methylmercury compounds are isolated from the sample matrix as methylmercury chloride (MeRgCl) by distillation. The distillation procedure is based on a series of...
