Hamid Abdolvand - starting new group at Western
Hamid Abdolvand is about to take up an Assistant Professorship at the Western University, Ontario. We wish him every success as he begins the exciting task of setting up the Multi-Scale Deformation Lab in the Department of Mechanical and Materials Engineering, and look forward to continuing collaboration over the coming years.

Yuanbo Tang - Prizes
Yuanbo Tang was in Tokyo in August for the 4th UK-Japan Engineering Eduction League Joint Workshop. This was hosted by Prof Kikuo Kishimoto at Tokyo Tech's Ookayama Campus. Yuanbo gave a great 3 minute pitch for his work on grain boundary serration and talked enthusiastically about his work to all who dropped by his poster. He was award the Best Poster prize for his troubles. Earlier in the year Yuanbo was awarded a William R Miller Postgraduate Award by his college St Edmund Hall.

Building Bridges in Hong Kong
Dave Collins and Ed Tarleton spent a week at the Chinese University of Hong Kong running a Material Science course in a summer school organised by St Anne’s College. The summer school ran for 4 days, selecting 16-year old students local to Hong Kong. The Materials day was attended by a total of 100 students. The hands-on activities they organised by Ed and Dave included building bridges using lollipop sticks, then testing them to fracture- some of them weighing just 100g were strong enough to withstand 20kg! The students also got to see how Materials Science is important to sound devices, building and testing speakers, then examining resonance effects and standing wave patterns in a vibrating Chladni plate.
