Electron Microscope Unit

Richard Webster holds a PhD from the University of Bristol in Physics and is employed as a research associate in the Electron Microscope Unit at UNSW, Sydney - a Node of Microscopy Australia. Richard has over 10 years experience using transmission electron microscopes and has over 40 peer-reviewed publications regarding TEM application to an extensive range of materials. Richard’s role in the unit is to collaborate with researchers applying the latest microscopy techniques to enhance their research and answer their scientific questions and to teach researchers to use TEM. Richard is responsible for the JEOL F200 microscope and operates the aberration corrected (S)TEM, the JEOL GrandARM300F2.

RIS 2018 - insitu gas & heating holder for the JEOL F200 TEM.

Richard’s recent research has focused on the application of electron microscopy techniques to analyse interfaces and defects to interpret the relationship between micro- and nano-structure and macro-properties. In particular the role of stacking faults in enhancing catalytic properties of branched metallic nanoparticles, the strengthening properties of Ce precipitates in 3d printed Al alloys and the application of low dose imaging on 2d perovskite materials used for solar energy harvesting.
