Well to be fair their may be good reasons ZEN has not released this information.  Their is always the NDA's which may forbid it for competitive reasons.  ZEN has had many different companies and Universities rave about our graphite so I am thinking positive that ZEN Graphite/Graphene is one the best on Earth. I am in for the long haul.  I still mainain that a bonafide offer of $5US plus  with no other bidders would take us out at this point in time.
