Every solid or liquid has a surface. We probably take this for granted, but the surface of a material is particularly special. It is via the surface that the material interacts with its surroundings; so the surface is where corrosion begins, and it is what governs whether a medical implant will be populated by cells, or will prevent bacterial adhesion. In the chemical industry, tonnes of catalyst material are used in a vast array of processes, and in many cases it is the surface which governs their effectiveness – more recently, novel solar energy harvesting devices have been developed which rely on functionalisation of the surface, and which transfer a charge across an interface. This talk looks at what makes the surface of a material different from the bulk, and how research takes into account the nature of surface chemistry and physics to carry out specific functions.
