Graphene/Graphair and all of the little "Graph" family connections, has become really a remarkable nano-substance! That has some really cool benefits!
This New Graphene Invention Makes Filthy Seawater Drinkable in One Simple Step
2.1 billion people still don't have safe drinking water.

Using a type of graphene called Graphair, scientists from Australia have created a water filter that can make highly polluted seawater drinkable after just one pass.
The technology could be used to cheaply provide safe drinking water to regions of the world without access to it.
"It can replace the complex, time consuming and multi-stage processes currently needed with a single step."
Developed by researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Graphair is a form of graphene made out of soybean oil.
Graphene - a one-atom-thick, ultrastrong carbon material - might be touted as a supermaterial, but it's been relatively expensive to produce, which has been limiting its use in broader applications.
Graphair is cheaper and simpler to produce than more traditional graphene manufacturing methods, while retaining the properties of graphene.
One of those properties is hydrophobia - graphene repels water.
To turn it into a filter, the researchers developed a graphene film with microscopic nanochannels; these allow the water through, but stop larger pollutants with larger molecules.
