Blocks all particles and conducts heat. Essentially this allows for a variety of things. For those who have wanted an pressure "cap", this could function as one (like all walls) while still conducting heat like, for instance, DMND would. This could aid in lasers too, as THDR could be used. (To ensure highest temp possible.) Also, there are a few projects of mine, that I can't describe in full, this would aid in. (Secret weapon.)
@dnerd It would seem entirely possible. Its just never been done before, which is very very weird. (Maybe that might hint that it is impossible...) I don't know.
