Improving the stability of iridium-oxide anodes for hydrogen production
Polymer electrolyte membrane water electrolysers (PEMWE) represent many advantages over conventional alkaline electrolysers including the ability to operate at high current density as well as being able to better cope with intermittent use that would accompany the use of renewable energy sources such as wind and solar power. This project will look at improving the understanding of oxygen evolution reaction (OER) catalysts stability and dissolution mechanism as well as build on methods for standardised short term accelerated testing in aqueous acidic media that can better benchmark stability of OER catalysts for PEMWE applications.
Development of a novel approach for the direct measurement of effective dose in neutron and gamma fields
The aim of this PhD project is to develop a novel dosemeter that is sensitive to the energy and the direction of gammas and neutrons, allowing it to provide for the first time a direct estimate of the effective dose (the quantity in which dose limits are actually expressed). By combining the detector technology with modern machine learning techniques for analysing the signals, such a device could become a new reference instrument for neutron and gamma dosimetry
Development of new methods for measurements and modelling techniques for accurate greenhouse emission estimates
This PhD project developed different measurement and modelling techniques for improving methane emission estimates of different sources in the UK. Having more accurate figures should increase the urgency of acting now. Cutting methane emissions is the fastest opportunity we have to immediately slow the rate of global warming and it’s an opportunity we can’t afford to miss.
