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. 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 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
Janus particles and nanorattles: new materials for paint technology. This project will pave the way for self cleaning paints that achieve opacity with greatly reduced titanium dioxide levels. Painted surfaces will maintain their clean and new look for longer and a clean town look will be much more readily maintained. More efficient use of titanium dioxide will reduce the need for sand mining and reduce the cost of quality paint.
Polymer micro-capsules for stain-resistant paint. This project aims to create an advanced micro-capsule system to be used in the manufacturing of high-performance waterborne paints on a large scale. Surface coatings seal, strengthen, and decorate the majority of surfaces in the building industry.
