Paper, "Theory-based design of sintered granular composites triples three-phase boundary in fuel cells", in which we apply insight from packing of granular matter to improve fuel cell technology, has been published (Phys. Rev. E 96, 052903 (2017)).

Clara Wanjura has joined us as an ERASMUS student for part of her masters. Clara will be working with me and Dr Eiser in the next six months on a theoretical description of the structural organisation of granular matter.

David King started his PhD with me and Dr Eiser. He will be working on extending the statistical mechanics of granular matter to describe dynamic systems with the connectivity formalism.

My student, Shahar Amitai passed his viva with minor corrections. Congratulations Dr Amitai!
