Overview
Magnetic resonance imaging (MRI) in hospitals non-invasively scans a patient providing grey-scale images for medical use. Image contrast may arise from the variation of a relaxation time, called T1
, in different tissue types. Professor Faux's inaugural lecture is about a specialist technique that measures T1 as a function of magnetic field strength and which, uniquely, probes the nano-dynamics of water in porous material, including biomaterial. Professor Faux's “3-Tau Model” is described. Potential applications are then discussed for catalysts (biofuel), cement paste, drug-delivery hydrogels, creams and pastes, foodstuffs, and in cancer progression assessment.

Professor of Physics
Biography
David obtained a First-Class Honours degree in Physics from the University of Nottingham in 1983 followed by a PhD from the University of Birmingham three years later. A two-year spell as a Postdoctoral researcher at North Carolina State University preceded his appointment as a Lecturer in the Physics Department at the University of Surrey in 1988. For nearly forty years, David has worked as a theorist and computational modeller with specialism in the interpretation of nuclear magnetic resonance (NMR) relaxometry experiments on porous materials. His seminal 3-Tau Model maximises the dynamical and structural information that can be obtained from field-cycling NMR experiments, spawning a spin-out scientific consultancy business serving industry and academia.
