News

In May 2014 we welcomed two new postdocs to the group - Dr Daniel Haley and Dr Stella Pedrazzini, working on hydrogen embrittlement in metals and perovskites for nuclear waste storage respectively.
On 7th and 8th April 2014 an Atom Probe Workshop was held in the Department of Materials in celebration of Professor George Smith’s research over the past 50 years leading the Atom Probe research group. George retired from the group in 2011.
 
Hydrogen in metals (HEmS) -  headed by Dr Michael Moody and Dr Paul Bagot.
 
Radiation effects in perovskites - headed by Dr Philip Edmondson and Dr Paul Bagot (with Neil Young of the Electron Microscopy group)
 


Atom Probe Group

Atom probe tomography is a microscopy technique that provides 3D atom-by-atom imaging of materials with a uniquely powerful combination of spatial and chemical resolution. For more than 40 years, the Atom Probe Research Group in the Department of Materials at the University of Oxford has maintained a tradition of pioneering field ion microscopy research and in particular the development and application of the atom probe technique. The group is currently active in all aspects of atom probe research, including: establishing new materials applications, instrumentation and the development of 3D reconstruction and data analysis techniques.
