Join us at the Pessimist as we find out about new techologies. With interactive demos, you could even win some Pint of Science goodies!

There's plenty of (profitable) room at the bottom

Dr Nick Tucker (Reader in Manufacturing and Materials)

Land’s End to John O’ Groats is 1407 km. If this distance was a metre, then a nanometre (one billionth of that metre) would be about 15mm – about the diameter of a 50p coin. At the nanometre scale, things behave quite differently. As engineers, we can take advantage of electrostatic forces to produce some novel nanoscale products: we can take fish offal and make a material that is worth £3 million per kilo, filters that catch specific bacteria, and surprisingly strong composites.

What is superconductivity?

Dr Andrea Floris (Senior Lecturer)

What is a superconductor? Why does a superconductor superconduct? In this talk I will illustrate the main phenomena characterising superconductivity, as the vanishing of the electrical resistance below a certain temperature and the Meissner effect. I will then give some hints about the Bardeen-Cooper-Schrieffer theory of superconductivity, that is able to explain superconductivity by introducing the “Cooper pairs” of electrons. Finally, I will mention some recent theoretical advances together with some unsolved problems mainly concerning the “high-Tc” superconductors.
