Designing a Membrane Module for Determining the Permeance of High Fluxing Membranes and the Testing RTIL-Membranes for Dehumidification.
… operate, and take low process cost. Removal of water vapor from gases constitutes a significant expenditure of energy in our society. Dehydration via a membrane process would constitute wide spread energy savings. This thesis explores experimental issues involved with testing Room Temperature …

Miniaturized Fluorescence Biosensor for Studying Neuronal Events
… in aqueous media since the lipobeads are fully water miscible. The lipobeads also proved to be highly biocompatible in cellular studies. This is attributed to their phospholipid bilayer membrane, which is similar in structure to cell membranes. The dissertation will describe the analytical …

Protein refolding via immobilisation on crystal surfaces
… the immobilisation protein upon the surface of a watersoluble excipient (salt, amino acid or sugar) via a co-precipitation reaction in a water miscible organic solvent. These proteins can then be used as immobilised biocatalysts in both the aqueous and organic phase. In the immobilisation of …

Investigation of liquid carryover in the girdler-sulfide process for production of heavy water at the AEC Savannah River Plant
… process for the production of heavy water was carried out using 12 samples of carbon collected over a one-year time period. Organic impurities from the feedwater were concentrated by adsorption on carbon. Studies of methods for the drying of carbon showed that freeze drying resulted …

Development and Characterization of Advanced Polymer Electrolyte for Energy Storage and Conversion Devices
… terephthalamide) (PBDT) is a water-miscible system and forms a liquid crystal phase above a critical concentration. The diverse properties and broad applications of this rigid-rod polyelectrolyte may originate from the double helical conformation of PBDT molecular chains. We …

Anti-solvent precipitation and subsequent film formation of hydrophobic drugs for drug delivery
… are hydrophobic in nature, leading to poor water solubility and bioavailability in the gastrointestinal tract. Dissolution is a limiting factor in their in vivo performance, and increasing their dissolution rate is a major challenge. It has been proven that the dissolution rate is directly …

Electromechanical Transduction in Ionic Liquid-Swollen Nafion Membranes
Traditionally, water has been used as the diluent for ionomeric polymer transducers. The water mobilizes the counterions within the polymer and allows electromechanical transduction to occur. However, these water-swollen devices have limited stability when operated in a non-aqueous environment. In …

Chemical aspects of saponin bioactivity and ovine photosensitization diseases
… vitro, required the use of small percentages of water-miscible organic solvents and phosphate buffer solutions to obtain homogenous aqueous solutions. Inhibition of S. parasitica growth was seen at triketone oil concentrations of: (i) 150 and 200 ppm using aqueous solutions containing 0.5% and …
