The event of the year is back, Friday 20th April - The Matsoc Ball! Yes it's on a FRIDAY, so no uni the next day! There has been a change of location from previous years to the Mercure at Piccadilly Gardens, with a magical, enchanting theme - Mid Summer Night's Dream. The ticket price is cheaper too, due to the hard work of the committee and help from the Head of School, William Sampson. Tickets include a beautifully cooked three-course meal, half a bottle wine and a sparkling welcome drink on arrival. There will be live music and entertainment, with a photobooth and much more. The menu is attached we a range of choices so there is something for everyone. Seating arrangements are ten people per table. Food orders and seating options can be emailed to email@example.com. We welcome all materials staff and students, their friends, dates and whoever else you'd like to bring along to a magical and enchanted night.

The ability to harness the functional properties of heme proteins within a solid-state material affords a number of commercial advantages such as stability and recyclability in heterogeneous biocatalysts and biosensors. To produce solid-state heme proteins we employ a recombinant coiled coil silk protein from honeybees as a de novo engineering scaffold. This recombinant protein can be produced at commercially viable levels, the protein sequence can be precisely manipulated using molecular biology, allowing very fine control over the properties of the heme-binding sites, and the protein can be fabricated in a variety of solid-state material forms such as films and sponges. We introduce heme cofactors to the silk materials and they interact through specific binding and coordination sites akin to naturally occurring proteins. We will outline heme protein materials we have developed for nitric oxide breath sensing, oxygen reduction electrocatalysts and hydrogen evolution. References 1. T.D. Rapson et al. (2015).
