Robert Murray-Smith, "Graphene Man" as I like to think of him :D, is a retired PhD chemist who has a really cool Youtube channel where he touches on lots of interesting science related subjects and has made numerous videos where he goes into all kinds of intricate details concerning graphene; most of which are made right from his kitchen counter! Oh and, be sure to take a look at his videos concerning his new invention he calls the Super Capacitor EESD, which is an amazing graphene based super capacitor with a weight to storage capacity ratio well beyond what's been attained by others working in this area. Go check out his channel!
