Graphene’s love affair with water

Graphene has proven itself as a wonder material with a vast range of unique properties. Among the least-known marvels of graphene is its strange love affair with water. Graphene is hydrophobic — it repels water — but narrow capillaries made from graphene vigorously suck in water allowing its rapid permeation, if the water layer is only one atom thick — that is, as thin as graphene itself. This bizarre property has attracted intense academic and industrial interest with intent to develop new water filtration and desalination technologies.ScienceDaily

Imagine that! Some months ago I wrote about Graphene’s great potential due to its complex molecular structure, but who knew that this structure has the potential to provide safe drinking water for billions of people living near our oceans?

This unique property of Graphene- that it allows H20 to flow through it but not salt- is a godsend for humanity. Hurrah for science!

On Valentine’s Day a University of Luxembourg study revealed that artificial graphene has been developed. What? Yes, artificial, as if graphene itself isn’t itself artificial enough.  Here is the report:

A new breed of ultra thin super-material has the potential to cause a technological revolution. “Artificial graphene” should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting. For the first time, scientists are able to produce and have analysed artificial graphene from traditional semiconductor materials. – ScienceDaily

The reason that graphene is so versatile is its unique molecular structure. One-atom thick, graphene copies what bees already understand: that a hexagon is the best pattern for compactness.  Here is a drawing of the artificial graphene structure. Note that each intersection of a line of electrons intersects 6 other lines, thus producing a fluid path for electron transmission.

    1. Before he took office or after? Of course that eliminates all of the assassinated presidents or those who died in office. FDR and Kennedy therefore pose an interesting conundrum.

      As you post this comment on Presidents’ Day, you must be thinking of either Washington or Lincoln. And it surely isn’t Lincoln. Thus, it must be Washington.

      Didn’t he own a cluster of cherry trees or something?
