Why does nanotech have an identity crisis? Aside from not clearly defining itself (and not differentiating from nano-scale - that is millennia old), the reported breakthroughs seem like more chem 101 or high school shop.
A top university makes graphene using "nitro acid - same mix we’ve used for nitroglycine) and ultrasonics). A previous big university breakthrough method for graphene (a single layer of graphite) was to peel off a layer from a block of graphite using Scotch Tape.
Need some graphite for your homegrown graphene factory - look inside of an old car generator for the brushes. The other problem with nanotech is that it is an overlay superimposed upon well established sciences, including chemistry, physics and biology (we might add molecular mechanics and other newer areas, too). Chemistry has worked the nano zone, and below (sub-nano) for centuries - and that’s why so much nano-stuff comes from chem labs.
