The Kinetic Resolution of Secondary Alcohols Through A Tandem Enantioselective Silylation and the Synthesis of Bis(Oxazolidinyl)Pyridine Metal-Organic Complexes
… aldol reaction. The design of a bi-functional organic chiral catalyst, which comprises of a Lewis base acetate anion paired with a chiral quaternary ammonium cinchona alkaloid, is discussed. We found that when the addition of a silyl ketene acetyl to benzaldehyde is catalyzed with our …

Supramolecular organisation, conformation and electronic properties of porphyrin molecules on metal substrates
… level studies of porphyrin molecules adsorbed on metal surfaces via Low Temperature Scanning Tunneling Microscopy/Spectroscopy (STM/STS), supported by complementary X-ray absorption experiments. Intermolecular and molecule-surface interactions of tetrapyrdil porphyrin (TPyP) on Ag(111) and Cu(111) …

Influence of protozoan grazing on the marine geochemistry of particle reactive trace metals
… the chemistry of particle-associated trace metals. This is due both to the importance of protists as consumers of bacterial-sized particles, and to the unique low-pH, enzyme-rich microenvironment of the grazer food vacuole. This thesis examines the role of protozoan grazers in the marine …

Studies of the complexation behaviour of transition metals applicable in membrane technologies
Many industrial processes make use of metal ions. These metal ions, however, end up in several effluent streams. Due to very strict discharge values, new technologies are constantly emerging for treating and purifying all kinds of wastewater. One of these innovative technologies is the Supported …

Recovery of the Mersey Estuary from Metal Contamination
… and still contains high concentrations of trace metals and organic compounds. A combination of hydrodynamic, sedimentary and geochemical processes are responsible for maintaining trace metal concentrations at present-day levels. The distributions of trace metals in bed sediments reflect changes …

Monolayer terpyridyl metal complexes for high-efficiency electrochromic materials
… of ECMs in the industry is limited to mainly inorganic metal oxides, conjugated conducting polymers, and liquid crystal-based materials. Hybrid metal-organic materials belong to a relatively new class of ECMs that offer exciting properties of extended stability, great color variability and the …
