Turning saltwater into clean drinking water is an expensive, energy-intensive process, but could the wonder material graphene make it more accessible? New Discovery Could Unlock Graphene's...
========== Graphene is the sexy new wonder material that
seems to have a million and one uses. From thin flexible screens to solar cells
that work when it’s raining, people are finding all sorts of potential applications
for this one-atom thick sheet of carbon. Now scientists have added another trick to
graphene’s repertoire; making seawater drinkable. Desalination is not a new concept; Israel
gets over a quarter of its fresh water from the mediterranean sea. But graphene could make the whole process
much more efficient. The main technique used for large scale desalination
is called reverse osmosis. Normal osmosis is where water flows across
a semipermeable membrane to areas of higher saltiness, if you were one of those kids that
poured salt on snails, causing the s...
