Welcome to the Barbour Group home page. We mainly focus on the discovery, design, assembly and characterisation of new functional materials with interesting properties. In particular, we are interested in exploring and understanding structure-property relationships relating to (i) porous materials and (ii) materials that undergo unusual thermal behaviour (e.g. anomalous thermal expansion, thermosalience, phase transitions, etc.). Please visit the Research Page of this web site for more information on what we do.
