Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less
PRODUCTION OF OPTIMAL MICROSTRUCTURED POLYMER OPTICAL FIBRE. Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow i ....PRODUCTION OF OPTIMAL MICROSTRUCTURED POLYMER OPTICAL FIBRE. Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow improved draw reproducibility and fibre uniformity so that commercial quality fibres can be produced at economic rates. We will establish quantitative relationships between drawing parameters and optical properties, thus developing optimal designs and production processes.Read moreRead less
Nanostrutured Magnesium-base Composites for High-density Hydrogen Storage. This project aims to develop nanocrstalline magnesium-based composites for effective hydrogen storage, overcoming two main technical barriers of current metal hydride systems: high charging/discharging temperature and slow kinetics. Nanoscale catalysts based on mesoporous carbons and metal nanoparticles will be introduced into the magnesium to increase storage capacity and increase the rate at low temperatures. Fundament ....Nanostrutured Magnesium-base Composites for High-density Hydrogen Storage. This project aims to develop nanocrstalline magnesium-based composites for effective hydrogen storage, overcoming two main technical barriers of current metal hydride systems: high charging/discharging temperature and slow kinetics. Nanoscale catalysts based on mesoporous carbons and metal nanoparticles will be introduced into the magnesium to increase storage capacity and increase the rate at low temperatures. Fundamental understanding on the effects of catalysts, and adsorption and desorption mechanisms will be obtained to optimise the composite materials. This project will lead to effective and practical technology for hydrogen storage that will meet the target of commercial fuel cell vehicles.Read moreRead less
