“ Graphene is sort of like the world’s great interfacial modifier. It confers chemical, electrical, mechanical, and thermal benefits” – Joe Adiletta, Volexion | Image: Volexion:

Can you tell us about Volexion’s graphene coating technology? How and why is it being developed? Our technology was originally developed at nanotechnology professor Mark Hersam’s lab at Northwestern University. We make a low-cost, high-performance graphene material – that’s important because historically you’ve only been able to get a low cost, low performance material or …
