A reliable physical model of molecular motion in crystals. The scientific benefits would flow, in the first instance, to the large national and international communities of scientists whose research makes use of the results of X-ray diffraction experiments. Applications of the research to amino acids and peptides will benefit investigations into the structure and molecular dynamics of biological systems, including proteins and enzymes.

The scientific benefits would flow, in the first instance, to the large national and international communities of scientists whose research makes use of the results of X-ray diffraction experiments. Applications of the research to amino acids and peptides will benefit investigations into the structure and molecular dynamics of biological systems, including proteins and enzymes. Studies of charge densities in crystals will obtain a standard tool for improved modelling of molecular motion, resulting in physically more realistic charge density functions, and hence greater insight into the relationship between properties of crystals and their constituent molecules.Read moreRead less
Electronic and Optical Properties of Doped Titanium Dioxide. Titanium dioxide, is widely used as a white pigment, owing to its high refractive index, second, only after diamond. Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify ....Electronic and Optical Properties of Doped Titanium Dioxide.

Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify the specific electronic cause of the yellowing process, the nature of the Al defect,it's effect on the electronic structure of rutile, and the electronic perturbations that may occur when other dopants are used.Read moreRead less

Crystal engineering is an exciting modern branch of chemistry that seeks to understand intermolecular interactions in the context of crystal packing, and to use this understanding in the design of new materials with desirable physical and chemical properties. This project will considerably extend our already significant contribution to the detailed analysis of intermolecular interactions in molecular crystal structures. It will achieve this by a substantial enhancement of our novel visualization tools, by improving upon current approaches to the analysis of theoretical and experimental crystalline electron distributions for molecular materials, and by ensuring the widespread availability of resulting software to all researchers.Read moreRead less

This project will make a novel contribution towards the creation and optimisation of new optically-active materials, an objective central to future photon science and information technology. By developing and implementing innovative approaches in the charge density analysis of high-resolution, low-temperature single-crystal X-ray diffraction data, we will obtain in-crystal estimates of the electronic part of molecular (hyper)polarisabilities and related bulk susceptibilities, for crystals of selected important organic nonlinear optical (NLO) materials. The program will exploit advances in CCD technology for X-ray data collection, procedures for electron density and wavefunction fitting, and analysis of molecular dynamics in crystals.Read moreRead less
