Nano-sponges on graphene make efficient filters of industrial wastewater

EXCERPT:

The end result was a two-nanometer-thick layer of COF on a single-atom layer of graphene, which increased the maximum capacity of the material for holding organic dye molecules. The graphene itself has fairly large pores, allowing the water to flow through quickly while the COF does its work.

Interesting article about using graphene with other materials to filter unclean water.

h/t to Red Badger for finding this and pinging me to it.

They use something VERY similar in our area...It almost looks like a reconfiguration...more than something new.

It’s been rather slow, but in time someone will make a big
discovery that will help incorporate graphene into items
that will have a broad base of support.

It seems to be an amazing resource.

Oh yeah, they had that years ago.

Forgotten technology! /s

How much deeper would the ocean be if it didn’t have sponges

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.

With carbon — all plants’ necessary food — being reduced at consistent levels, the new trees, shrubs and grasses wouldn’t last long.
