Every article, instrument, machine or device we use depends for its success upon materials, design and effective production.
We work on a wide range of materials topics including new material development, optimising of materials processing, testing and evaluation at component scale and at high spatial resolution, modelling and failure analysis. Much of our work is related to materials and processes for renewable energy generation, energy efficiency, carbon capture and storage. We also use biological and bio-inspired processes to develop new functional materials.

We are developing exciting new processes to form nano-diamonds. These have important applications as biological markers as a result of their unique optical properties.
Nanoparticles are used in a wide range of products – all the way from cosmetics to water treatment in developing countries. We design nanoparticles with novel properties to improve, for example, sunblocks or lubricants.
WS2 fullerene-like nanoparticles for lubricants
We take our understanding of behaviour at the atomic level and use it to create models which describe relationships between the structure of a material and its properties. This work has been used in the design of real products such as energy efficient solar-control coatings and self cleaning glazings.
Solar-control coating on architectural glass
We are developing new materials for use in renewable energy generation and are using our knowledge of material failure mechanisms to help improve the design of long life plant for tidal power generation and carbon capture and storage systems.
We are developing inorganic catalysts for carbon capture, utilisation and storage through ex-situ mineralisation. The purpose is to find permanent storage of CO2 with minimal energy input and accelerate the rates of the CO2 capture.
We are looking at methods to reuse/recycle difficult materials such as glass fibre-reinforced polyester composites and rare earth magnets and are developing novel methods to extract new and replacement raw materials using low energy processes.
Shredded and milled GFRP waste for incorporation into new composite products
Engineering of novel biomaterials has the potential to deliver exciting future technologies. We are currently working on materials for orthopaedics and biosensors.
Soft matter is a generic term for a range of materials with low compliance such as polymers, foams, emulsions and colloids and biological materials and is characterized by multi component mixtures, large ranges of length and time scales and many interacting degrees of freedom, leading to complex structures, phase behaviour and dynamics. We are working on dynamic functional polymer systems, organic electronics and novel foams based on polyHIPEs for impact resistance and tissue scaffolds.
