Event details
Professor Pete Nellist, Oxford University, Scientific Champion of SuperSTEM facility, will be visiting the University of Southampton to present 'Atomic resolution imaging and analysis of materials at SuperSTEM'
SuperSTEM is the EPSRC National Facility for Aberration-Corrected Scanning Transmission Electron Microscopy. It has been in operation at the Daresbury Laboratory for more than 10 years, but its funding was recently renewed through the EPSRC Mid-Range Facilities initiative. In this presentation, I will highlight some of the scientific contributions that SuperSTEM had made that highlight the capabilities of the facility. These include applications to the structural determination of crystal defects, heterostructure interfaces, identification of impurity atoms in graphene and probing of their bonding through electron energy-loss spectroscopy (EELS), and measurements on Fe nanoparticles in liver tissue. A new instrument for SuperSTEM has been funded, with a target EELS resolution of 30 meV that aims to allow the detection of bond vibrations. I will conclude with details of how the facility may be accessed by researchers.

Speaker information
P D Nellist (University of Oxford), Scientific Champion of SuperSTEM facility,Professor Nellist presents this talk on behalf of the SuperSTEM facility and in his role as Scientific Champion of the facility. Prof Nellist took his BA and PhD at Cambridge University before heading west to a post-doctoral position at Oak Ridge National Laboratory in Tennessee. He was tempted back to Cambridge by a Research Fellowship at Magdalene College, and shortly afterwards was awarded a Royal Society University Research Fellowship. He transferred this fellowship to the University of Birmingham for two years, but in 2000 he decided to try something outside academia by getting involved in a start-up company in Seattle. In 2004, he realised that he was starting to miss teaching so decided to return to academia, first to a lectureship at Trinity College Dublin, and two years later to his current position as Tutor for Materials Science at Corpus and Professor of Materials in the Department of Materials Science. Prof Nellist collaborates with a number of groups worldwide, and sits on the Electron Microscopy and Analysis Group committee of the Institute of Physics, the Electron Microscopy Section Committee of the Royal Microscopical Society, and the INSPIRE Ireland Scientific Advisory Board. In 2007 he was awarded the Burton Medal by the Microscopy Society of America for his contribution to the field.
