What limits CO2 diffusion inside leaves? Dissecting the diffusion path with Arabidopsis mutants. Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis. Discrimination between isotopes is affected by carbon dioxide dif ....What limits CO2 diffusion inside leaves? Dissecting the diffusion path with Arabidopsis mutants. Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis. Discrimination between isotopes is affected by carbon dioxide diffusion within leaves and key steps in this process will be identified through the use of Arabidopsis mutants. Better representation of this process in models will improve estimates of terrestrial photosynthesis and climate change forecastsRead moreRead less

The management of greenhouse and other acid gas emissions is vital to a sustainable future of both the economy and the ecosystem. This project will develop novel nano-materials for gas separation by tethering organic functional groups to the surface of porous inorganic supports. These materials offer the promise of combining the high selectivity and high capacity of liquid phase absorption systems with the rapid transport rates of gas-solid adsorption systems. Success would open up several new possibilities for reengineering gas separation systems based on the use of these materials in solution, as solid phase adsorbents (pressure swing adsorption) and/or as permeselective gas membranes.Read moreRead less

This project underpins the development of carbon dioxide (CO2)-neutral fuels for the future. Fuels account for around sixty seven percent of the global energy market. The Solar-Biofuels Consortium (www.solarbiofuels.org) is targeting this market by developing high efficiency second generation microalgal biofuel systems for the production of bio-diesel, bio-methane and bio-hydrogen (shown on Catalyst 2007). The solar-powered microalgal bioreactors can be located on non-arable land (eliminating competition with food production) and be coupled to carbon sequestration. Closed systems also minimize water use. This technology differs from most others (that is, clean-coal, nuclear, solar, wind, geothermal) as these target the electricity market.Read moreRead less
