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 39 group members including 19 PhD students (8 students being co-supervised) and 20 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with more than 10 nationalities represented.
Congratulations to David Halat who received the BRSG (British Radiofrequency Spectroscopy Group) Founder's Prize on the 14th December for his talk on "17O solid-state NMR of functional paramagnetic oxides for energy conversion and catalysis"!
Welcome to Robert Weatherup who joined our group in December!
Congratulations to Wei Meng (PhD student) and Oliver Pecher (Post-Doctoral researcher) for winning the STFC Experimental Design Award for their project entitled "High temperature synchrotron in situ X-ray diffraction to unravel structural changes of cathodes in Li- and Na-ion batteries"!
Congratulations to Dr Beth Howe for her successful viva on the 21st of November!
Kent Griffith won a "Chemunicate" contest by presenting a description of his research project on developing advanced lithium ion batteries. A nice graphic illustrating his research is featured on the Compound Interest website.
