While there is a strong initiative to develop new (ideally renewable) energy sources for future applications, there is still a requirement for sustaining existing energy solutions, but with improved performance and efficiency. In the foreseeable future, there will continue to be a need for efficient steam based turbo-machinery for power generation, but with greater operating flexibility, to...

Understanding the fundamental properties of materials of relevance for alternative energy technologies is crucial in addressing the global challenge of cleaner sources of energy. In this presentation I aim to demonstrate the important role that neutron scattering now plays in advancing the state of the art of the fundamental understanding of proton conducting oxides, which show potential to be...

We present a SANS study of radiation-grafted fuel cell membranes
containing styrenesulfonic acid. The influence of the nano-structure
of the aqueous phase on the proton conductivity is studied.
We model the structure of the aqueous phase using a stochastic approach and estimate the tortuosity of the aqueous phase via the self-diffusion of a Brownian walker. We find a strong dependence of...
