MY RESEARCH QUESTION

In a bulk piece of material, there is a formula for the number density of vacancies as you go into the material from the surface. The number density is higher near the sur-face.

So, if you have a small crystal, it should have a high defect population than bulk material.

Oxford’s former students competing in the Olympic Games in Beijing have had an impressive weekend securing an array of gold and silver medals.

Last week Daisy Dick won a bronze medal in Eventing and now her Oxford alumni Team GB colleagues have added to her win.

On Saturday 16 August, Peter Reed and Andy Triggs-Hodge won a gold medal apiece in the rowing four, while Acer Nethercott and Colin Smith won silver in the men’s rowing eight – accompanied by Josh West who is a University researcher.

On Sunday 17 August, Paul Mattick made the rowing finals of the lightweight four and came in fifth place, while USA rower Jamie Schroeder took the same spot in the quadruple sculls final.

Buffy Williams of Canada, who studied at St Hughs in 2004, got fourth place in the women’s eight final.
