Atomistic Mechanisms of Stress Relaxation in Amorphous Materials. Amorphous materials represent a major thrust in the search for new materials. Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals.

Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals. Ceramic glasses are finding increasing applications in data storage, photoelectronics and fibre optics. The greatest obstacle to the application of amorphous solids is their brittleness. The goal of this project is to use accurate computer simulations to provide detailed pictures of how atomic motions relax stress in very different types of glasses and, through this insight, explore ways of modifying the mechanical properties of these materials.Read moreRead less

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation.

Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less
