The project aims to engineer positively charged metal complexes and use them to explore the chemistry of bound activated alkane ligands. The transformation of cheap, plentiful alkanes into more valuable products is a major quest in chemistry, and complexes of alkanes bound to metals are expected to play a key role in transformations of alkanes. The project intends to use the activated metal bound alkane to transform the normally inert alkane into compounds with desirable functional groups. This should make the synthesis of alkane complexes stable at room temperature in solution a realistic possibility. These cheap, plentiful alkanes can be turned into more valuable products, bringing benefits to industry.Read moreRead less
Alkane transformations through binding to metals. Alkanes are fully saturated hydrocarbons and they are the major components of petroleum, including natural gas and liquid hydrocarbon fuels. They are abundant but finite, and their primary usage has been as fuels since they burn readily and release energy. Alkanes are relatively low-value, high-volume chemical feedstocks which are not easy to convert into more useful value-added materials. This project focuses on developing positively charged met ....Alkane transformations through binding to metals. Alkanes are fully saturated hydrocarbons and they are the major components of petroleum, including natural gas and liquid hydrocarbon fuels. They are abundant but finite, and their primary usage has been as fuels since they burn readily and release energy. Alkanes are relatively low-value, high-volume chemical feedstocks which are not easy to convert into more useful value-added materials. This project focuses on developing positively charged metal-based compounds that can bind directly to alkanes to increase their reactivity and enable their transformation into higher value products such as alcohols and olefins which are important chemical feedstocks.Read moreRead less

A New Spin on Liquid Hydrogen: Controlled Cold Energy. While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive.

While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through the provision of controllable refrigeration (so-called 'cold energy') following regasification. In particular we will measure, optimise and exploit the highly endothermic catalysed conversion of para- to ortho- hydrogen, which can provide up to 525 kJ/kg of cooling at convenient temperatures.

This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in situ. This will enable the control of stereochemistry in photoredox reactions – not possible with standard catalysts - and establish other useful synthetic transformations. These strategies will make it easier to prepare valuable classes of organic molecules – efficiently, safely, and cost-effectively.
