Asymmetric Synthesis of Chiral Phosphines, Arsines, and Stibines. There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides.

There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides. This project is aimed at a generalised asymmetric synthesis of the critical components of these enzyme mimics, notably enantiopure chiral phosphines, but also chiral arsines and stibines, by a highly innovative approach that involves novel six-electron phosphenium, arsenium, and stibinium cations that are themselves stabilised by chiral phosphines so that chemical breeder reactions are possible. The use of chiral auxiliaries from the natural pool and from biotechnology will also be investigated.Read moreRead less

Summary
Multi-dimensional polymer characterization facility. The microstructure of polymers dominates their physical properties. This integrated facility will create a world-leading means of characterizing in multiple dimensions the microstructure of complex polymers, eg copolymers and branched polymers. The facility will yield information on the distributions of chain end-groups, monomer microstructure, and branches, as functions of molecular weight.

This integrated facility will create a world-leading means of characterizing in multiple dimensions the microstructure of complex polymers, eg copolymers and branched polymers. The facility will yield information on the distributions of chain end-groups, monomer microstructure, and branches, as functions of molecular weight. The facility will provide otherwise unobtainable data for a set of projects exploring questions ranging from how new synthetic materials with tailor-made properties can be created, through to how our understanding of natural polymers can be advanced to improve crop utilization.Read moreRead less

Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less
The effects of local strain on the crystal chemistry of solid solutions. The concept of the solid solution, the substitution of one kind of atom for another in a crystal structure, is a central idea in both mineral sciences and solid state chemistry. Such atomic substitutions alter local crystal chemistry and hence always introduce strain into crystal lattices. In this project we aim to characterize this substitutional strain. Ultimately this should lead to a better understanding of the geologic ....The effects of local strain on the crystal chemistry of solid solutions. The concept of the solid solution, the substitution of one kind of atom for another in a crystal structure, is a central idea in both mineral sciences and solid state chemistry. Such atomic substitutions alter local crystal chemistry and hence always introduce strain into crystal lattices. In this project we aim to characterize this substitutional strain. Ultimately this should lead to a better understanding of the geological history of rocks, improvements in metal recovery from ores and to the design and synthesis of new materials.Read moreRead less

The objective of the proposed research is to improve our understanding of such reactions. State-of-the-art quantum chemistry calculations will be used to examine a broad range of hydrogen-abstraction reactions, and to obtain accurate information about the factors that influence such reactions. Building on this work, more detailed case studies will be performed in two important areas: the hydrogen-abstraction steps in biochemical reactions mediated by coenzyme B12, and chain-transfer processes in conventional and controlled free-radical polymerization.Read moreRead less
