Interesting: 10 Uses for Graphene.
They use something VERY similar in our area...It almost looks like a reconfiguration...more than something new.
I believe I’ve seen this sort of thing discussed in science fiction — specialized nano-filters for seawater. Seawater contains a lot of valuable material in trace amounts.
The concept seems to involve a series of vats separated by nano-filter walls which are permeable. In one vat, all the gold drops out, in the next vat, all the sodium, in the next, all the potassium, and on and on, then you get a vat of clean fresh water which is pumped to a city.
I don’t think we’re there yet, but it would be a nice low-energy mining/desalinization model.
If they can make this work for desalination—and do it for a price such that desalinated seawater costs $300@acre and the waste brine gets converted to its constituent elements which are then sold for a profit....-—the world changes almost beyond recognition.
Why? Because cheap desalinated seawater will enable all the worlds deserts to be turned green. the habitable size of earth will double.
