Mark Hersam is a professor of Chemistry and Materials Science Engineering at Northwestern University. He joins Nate in The Show About Science studio to talk about nanotechnology, carbon nanotubes and how a pencil and some scotch tape led to the Nobel Prize winning discovery of graphene. This video on graphene from The Verge Science was really helpful when researching this episode: https://www.theverge.com/2018/7/10/17548362/graphene-material-breakthrough-science-technology-hype Learn more about Mark's work here: http://www.hersam-group.northwestern.edu/ This episode is sponsored by MEL Science.
