I know nothing.about those last names you mentioned.. Btw Brainchip have so something going with NASA we've heard nothing about.
At the end of the day fgr have pristine graphite that produces pristine graphene that I think is a waste on mundane functions, possibly why the cavitation is being explored for those fields as it doesn't matter on poorer quality.
I'm extrapolating from info read b4.
VFF is more valuable and so is pristine
I see it like wasting a fine red by mixing it with lemonade..
