The aim of this project is to develop novel characterisation methods that probe the structure and surface chemistry of carbons, ranging from highly graphitised thermal carbon black through ordered mesoporous carbon to disordered porous activated carbon. The project plans to develop a new generic molecular model based on wedge-shaped pores. Conventional parallel sided pore models fail to account for real structures and therefore for the physics of adsorption in real materials. The project then plans to back the theoretical model with high-resolution experimental measurements. It is expected that the model will unify the structural analysis for all carbons and account for all experimental isotherms within a rational and physically plausible framework.Read moreRead less

This project aims to address the intermittency of renewable energy sources using novel thermal storage media. Advanced heat transfer modelling and in situ neutron diffraction and imaging are intended to be used to optimise the microstructure of newly developed miscibility gap thermal storage systems. The new media store energy as the latent heat of fusion of one phase in a stable, high thermal conductivity inverted microstructure. The high energy density of the latent heat (0.5-4.5 Mega Joules/Litre) requires storage volumes as little as five per cent of those relying upon heat capacity and the metal matrix has a hundred-fold greater thermal conductivity than current systems. It is proposed that a range of such materials will be engineered for concentrated solar thermal and space heating applications.Read moreRead less
