There is some interesting dialogue as well under the articles.

So the Holly Grail of graphene is to be able to produce it in commercial quantities. The first company that can do this successfully will have a tremendous business advantage. BGU and their partners are some of the best researchers on the planet from what I can read. ZEN seems to be the best starting material to make graphene. I believe together, we have as much or better chances of solving the challenges of producing graphene in commercial quantities. If that happens, my $20 per share will seem ridiculously low.

Looking forward to the Trade Mission results!
