Garth Wilkinson gave a talk on Nanotechnology and Graphene. The nanotechnology aspects of Garth’s talk were a quick historical overview based on the seminal conceptual work by Richard Feynman & Eric Drexler, combined with a summary of some potential recent applications.
Some of the more interesting are nanobots & applications to medical treatments, though the largely unknown http://quotecorner.com/online-pharmacy.html biohazards were also highlighted. The latter part of the talk covered the important nano-material graphene, and was based a talk given by Garth elsewhere 3 years ago. It was illustrated by some AV clips on the subject by Prof. Martyn Poliakoff. The chemical & physical properties of nano-materials could differ radically from their bulk counterparts.
