here at the national physics laboratory — pretty impressive, isn't it — not only are they testing themapping system which is just one part of the equipment to actually test the graphene content in any item. is it notjust as simple as working out what percentage of graphene an item would need to be to qualify as graphene? the first issue is understanding the measurement of the material itself to say, well, is there graphene in there? are there graphites? when you look in a black powder there could be anything in it, so that is the first issue of having measurement procedures everybody can follow. if it's not dispersed through it, if it's clumped in one part, it may actually make the composite worse. i've actually got my hands on a whole vial of graphene. and with such qualities, isn't this rather a lot? what could you do with it? these are graphene flakes in a powder. you would imagine adding this into a composite. if you think of something like lightweight planes, fuel savings, this is the material you would need to put into the composites already used. 0k, and for our batteries and d
