Synthetic Ion Channels From Lipophilic Guanosine Derivatives
… but also demonstrate their potential applications in the areas of drug delivery, biosensors, antimicrobial agents and other molecular devices. In this thesis, lipophilic guanosine derivatives that combine both "molecular recognition" and "membrane soluble" features are utilized for the …

Ionic Mobility In Stuffed-Silica Minerals
… techniques, the dynamical behaviour of loosely bound cations in the stuffed-silica minerals nepheline, yoshiokaite and ß-eucryptite has been investigated. The investigation has been extended to include the feldspar minerals albite, K-feldspar and anorthite. The low-frequency dielectric …

Temporal variability in chemical cycling of the subterranean estuary and associated chemical loading to the coastal ocean
… gradient and therefore SGD. Fluxes of sediment bound cations to the ocean increased coincidently with sea level rise due to desorption. There was enhanced nitrogen attenuation during winter, potentially due to longer groundwater residence times, with greater nutrient delivery to coastal waters …

Hydrolysis and Toxicity of Aspartyl Peptides and the Influence of Metal Ions on Aspartyl Peptide Hydrolases in Salmonella Enterica Serovar Typhimurium
… sites of unequal affinity in DapE, Mn 2+ is bound to the low affinity site and Zn2+ to the high affinity site when DapE functions as a peptidase. Overexpression of DapE in the MPD dapE strain conferred strong growth on Asp-Leu as a Leu source indicating DapE functions well as a peptidase when …

Ru,Rh,Ru Supramolecular Photocatalysts within Nafion® Membranes: Ion-exchange, Photoelectrolysis and Electron Transfer Processes
… cationic complexes, and the study of polymer-bound cations may provide insight regarding Nafion® morphology by contrasting molecular size with existing models. The trimetallic complex, [{(bpy)2Ru(dpp)}2RhBr2] 5+, is readily absorbed by ion exchange into Na+ -form Nafion® membranes under …

Investigation of Temperature, Solution Strength, and Applied Stress Effects on Cation Exchange Processes in Geosynthetic Clay Liners
… (MSW) landfills and laboratory testing applications. Needlepunched-reinforced, double non-woven Na-B GCL specimens were conditioned in fluids of increasing ionic strength (DI water, 2 mM CaCl2, 50 mM CaCl2, and 200 mM CaCl2 representing control, pore water, mild MSW leachate, and harsh MSW …
