For now, graphene is known as one of the wonder of
science world. Graphene is a thin layer of carbon atoms, with only a single of
atom in thickness. It is one of the most promising materials discovered in a
long time. Graphene take all the praise because of its capability to reinforce
almost all of the inventions that human ever created. Despite of its fantastic
thickness, graphene is the most conductive material in the world. And believe
it or not, incredibly strong. It can be used for superconductor, anticorrosive,
bulletproof materials, and even water filter.
Researchers from the University Manchester in
England, have discovered one of the most important properties of graphene yet.
It’s impermeable to everything but water. It is the perfect water filter.
In an experiment, the University of Manchester
researchers filled a metal container with a variety of liquids and gases and
then covered it with a film of graphene oxide. It was unable to allow any
molecules leaving the container, except for water vapor. The graphene oxide
filter even prevented helium gas from pass through.
In another experiment, Dr Nair & Co. sealed
a bottle of vodka with the graphene filter. And again, this allowed just the
water to evaporate, and leave a super-vodka. It is easy to see the potential of
this new filter. With such horrible condition in consuming clear water in this
time, water filtration is one of the most valuable topics we can discuse. And
if graphene oxide really is completely impermeable to everything except water,
this new filter would make clean water out of anything, as easy as pouring a tea
on a cup.
