Sci-fi like green solutions 2 – Graphene in a flash!
James Tour, a professor of chemistry, computer science, and materials science and nanogenineering at Rice University. He tells us about an exciting new process to make graphene cheaply by a flash Joule heating method. Graphene, the hardest manmade substance, could then be used in a number of ways to lower greenhouse gas emissions, such as in adding it to concrete to strengthen and make it less GHG intensive. If the technology proves out, we may even be able to make enough graphene itself to use as a building material instead of using it to strengthen other materials.
