How to Make Graphene at Home for Fun

Video provides a good description and nice do-it-yourself experiments with the latest wonder material: graphene

I came across the video below from the blog Frogheart and considering the recent Nobel Prize for Physics and the near daily reports on graphene within the pages of Spectrum alone, I thought it worth posting here.

The video provides a demonstration in a very rough way for how one could manage to isolate a single layer of graphite to create graphene.

The presenter, Dr. Jonathan Hare, manages to bring up the issue of the speed at which electrons travel through graphene to discuss relativistic quantum mechanics and Dirac particles and still manages to make it accessible for a general audience.

Nice piece of work and will lead me to check out the video’s producers Vega Science Trust for more material.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
