This project aims to design and engineer photocatalytic ceria of systematically controlled grain sizes and morphologies, using doping methods to achieve pure and mixed quantum confinement (which enhances performance). The intended outcomes of the computation, fabrication, and validation approach are a fundamental knowledge of the processing-performance matrix and reproducible photocatalysts of optimised performance. While these ceramics will be applied as bioceramics, which can be activated by ultraviolet light, X-rays and ultrasound, the benefits will be applicable in energy (solar cells, photoelectrodes) and the environment (air and water purification).Read moreRead less

Biodegradable porous shape memory alloys by additive manufacturing. This project aims to create a class of biodegradable Fe-Mn-Si based shape memory alloys and use additive manufacturing to fabricate porous structures with desired properties from these shape memory alloys.

This project aims to create a class of biodegradable Fe-Mn-Si based shape memory alloys and use additive manufacturing to fabricate porous structures with desired properties from these shape memory alloys. Biodegradable shape memory alloys offer great promise for biomedical applications due to their unique biodegradability, shape memory effects and superelasticity. However, a huge knowledge gap exists in developing and fabricating biodegradable shape memory alloys with desired properties for biomedical applications. The project expects to fill the critical knowledge gap and open up new opportunities for biomedical applications of biodegradable shape memory alloys. This project will provide significant benefits through the creation of novel materials for application in the healthcare industry such as biomedical devices.Read moreRead less
Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description of filled soft viscoelastic solids, which include compressibility and yielding - two important new features.Read moreRead less

Interfacial Structures in Thermal Spray Coatings. The use of coatings on the surfaces of components provides high levels of resistance to mechanical damage, corrosion, oxidation or thermal degradation. As a result, coated components exhibit increased lifetimes and reliability. However, the durability of such components is still crucially limited by the quality of the coating. An improved understanding of the bonding mechanisms that occur during the deposition of such coatings, prepared through t ....Interfacial Structures in Thermal Spray Coatings. The use of coatings on the surfaces of components provides high levels of resistance to mechanical damage, corrosion, oxidation or thermal degradation. As a result, coated components exhibit increased lifetimes and reliability. However, the durability of such components is still crucially limited by the quality of the coating. An improved understanding of the bonding mechanisms that occur during the deposition of such coatings, prepared through thermal spray methods, will provide improvements in coating structure and thus, component performance and lifetime. This will benefit a wide range of manufacturing industries that use such coatings. Read moreRead less

Tissue Therapies, which holds the rights to commercialization of VitroGroR, is seeking to develop methods of delivering VitroGroR in its active form to the wound environment. Two solutions to this problem will be developed in this project; a bioactive bandage containing a novel combination of microspheres and a hydrogel matrix, and secondly an in-situ polymerisable matrix for treatment of deep wounds. The growth factor complex will be protected from aggressive proteases through encapsulation within microspheres, and the use of MMP-inhibiting comonomers.Read moreRead less

New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high tec ....New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high technology industries, as well as in harsh environments. Because we will be able to manipulate the structure and observe property changes, it should also give us a greater insight into the adhesion mechanisms used by many small animals and bugs.Read moreRead less
