The Grey group studies the nature of solid state materials by nuclear magnetic resonance (NMR), X-ray and Neutron scattering, electron microscopy and computational calculations. The materials we investigate have applications in supercapacitors, fuel cells, and batteries.
Our current research projects are described here and a full list of publications is available here. We currently have 40 group members including 21 PhD students (8 students being co-supervised) and 19 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with more than 10 nationalities represented.
Congratulations to Alexander Forse who received the Energy Sector PhD Thesis Award from the Royal Society of Chemistry, for his thesis on Nuclear Magnetic Resonance Studies of Ion Adsorption in Supercapacitor Electrodes.
In June, Michael Gaultois published an Op-Ed article entitled "Accurate science or accessible science in the media – why not both?".
In May, we went to our group retreat in the Wye Valley! This was an excellent time to exchange ideas and go hiking (see more in the Social Photo Gallery)!
The group has also welcomed Pierre Naeyaert, from the group of Prof. Chris Ling at the University of Sidney, who is going to work on Na NMR experiments on P2-type cathode materials.
Congratulations to Michael Hope who received the Detlef Müller Award for the Best Student Poster at the Developments and Applications of Solid State NMR conference in Varna!
