I’d imagine most of you have never heard of graphene. Graphene is
carbon-rich and only one atom thick. It thus qualifies as a near as
damnit two-dimensional substance….the first example of such a thing in
the real world. Despite being the thinnest material known to exist, it
is also the strongest material ever tested— 2-300 times stronger than
steel. A lot of atomic and sub-atomic stuff has this ability to defy the
size v importance obsession: graphene rocked the world of chemistry in
2004 when UMIST scientists discovered that it had remarkable properties
that allow it to conduct electricity better than any other common
substance.
As you might expect, most members of our beads-fixated species are
interested in how graphene can be used strategically and commercially.
China controls 70% of the known supplies of it, and it’s been named a
“supply critical mineral” and a “strategic mineral” by the United States
and the European Union. It makes semiconductors 100 times faster, and
would make every aeroplane 70% lighter. Phones and computer displays
made with it can bend and fold. And it has the potential to make people
and things completely invisible. Yes, that’s right: invisible.
But some possibilities are genuinely profound. As graphene is almost
all carbon – the chemical basis for all known life – it should be an
ecologically friendly, sustainable solution for an almost limitless
number of applications. Importantly, it renders solar energy 100 times
more efficient, and thus might well be the missing link for which some
of us have been hoping as an end to dependence on fossil fuels….and thus
interminable Middle Eastern violence.
