Graphene The so called “The Miracle Material” discovered as Stronger than steel, thinner than paper, better than copper at conducting electricity, and possessing unique optical properties, graphene is a revolutionary carbon based material. Graphene’s unique combination of superior properties can lead to futuristic products like electronic paper, bendable personal communication devices, and lighter and more energyefficient airplanes.
Graphene is discovered in 2002 by European scientists and professors Andre Geim and Kostya Novoselov with their students, when they pulled tiny shavings of graphite (pencil lead) off some discarded Scotch tape and look at it under a microscope. They discovered the possibilities for graphene’s practical applications in 2004 and demonstrated that the material can be used in place of silicon or copper to conduct electricity. Their groundbreaking research, conducted at the University of Manchester in England, was recognized by the 2010 Nobel Prize in Physics In 2014 the most conductive ... there are other materials that have one of those properties, but here it's combined in one very simple crystal." Novoselov informs graphene has applications in high-frequency electronics (touch-panels), opto-electronics (photonics - light) and
thermo-management (batteries), to name a few.
It's able to make the internet run 100 times faster and produce flexible, super-thin, almost invisible wearables, It's certainly different from the boring old silicon we're used to ,
So, as you can see, if it lives up to its potential it could change pretty, Graphene's good for all that too. It can even be used to create motion-sensing windows that read gestures, nanosensors that detect breast cancer and smartphone batteries that
recharge in just a few minutes. Sticky tape and pencils, Carbon-based materials are already changing the face of electronics, but would likely be immediately replaced by graphene if it is ever fully workable. Graphene can deliver what we all want - bendy phones and ubiquitous,
embedded electronics and wearables that communicate with each
"We have been talking about flexible, transparent, wearable electronics
for years, but so far this field hasn't really delivered, largely became
the materials aren't good enough," says Stijn Goossens, Postdoctoral
research engineer, Nano-optoelectronics, Institute of Photonic
Sciences (ICFO) in Barcelona.
A shirt with graphene ink in, say, a logo or a pattern could unlock a
security door for an employee, while a paper wristband with graphene
inks upon it could become an electronic ticket.
In the world of opto-electronics, graphene's sensitivity is helping
create spectral sensors for wearables that use light to reveal
The findings could revolutionise the production of the heavy water composed of a rare form of
hydrogen called deuterium, which is expensive to manufacture and
purify with existing technology. Others have found uses for graphene essentially to create super-fine
sieves for desalination (catching the salt from sea water, so creating
an inexhaustible supply of drinking water), cleaning-up oil spills by
removing all impurities in water, extracting radioactive materials from
water, separating hydrogen ions and even for mining and fracking.
And then a light appeared ...
Graphene could also be used to clean up nuclear waste contaminated with radioactive tritium, another hydrogen isotope that can be
separated by the graphene filter, scientists said. "Essentially, graphene is the finest known sieve. It can sieve particles smaller than an atom..." said Marcelo LozadaHidalgo
of Manchester University, the first author of the study published in the journal
Science. Graphene has already astonished the world of materials science with its range of unusual characteristics, such as its atomic scale thinness, extreme strength and high electrical conductivity. The latest study, by a research team led by professor Geim, discovered another novel property of graphene — its ability to filter the different atomic isotopes of hydrogen, namely tritium and deuterium, from ordinary hydrogen. The rare form of hydrogen, deuterium, is only present in Graphene could be used to detoxify Nuclear waste, The findings could revolutionise the production of the heavy water composed of a rare form of hydrogen called deuterium, which is expensive to manufacture and purify with existing technology.
