So what is graphene?
According to scientists graphene is the strongest material ever measured!
“It would take an elephant, balanced on a pencil to break through a sheet of graphene the thickness of cling film.”
said Columbia University Engineering Professor James Hone; continuing, "Our research establishes graphene as the strongest material ever measured,
some 200 times stronger than structural steel
(emphasis added) Source: Scientific American online
A graphene sheet is only one atom thick, so it takes 3 million sheets on top of each other to be the thickness of one millimeter!
It is so strong because it is made of Carbon atoms double-bonded together in a lattice.
Due to graphene's nature, it can comfortably stretch 20% of it's length/width. It can also conduct electricity better than copper wire! oh ya... and
it's invisible! (see through) but scientists are discovering some very weird things about this wonder sheet
Before we get into the anomalies and serious science let's take a look at...
What is graphene used for?
So we have the strongest material ever measured, 300,000 times thinner than the average human hair, it's see-through, and conducts electricity....
what would you make?
Some things created so far are a transistor and Integrated Circuit, by IBM scientists/Engineers
(discussed in ATS thread: First Graphene-Based Integrated Circuit Is a Major Step Toward Graphene Computer Chips, by JacKatMtn)
A company called Nanotrons has been working with nanotech since 2009 and has created "Conductive nanopaint" that is a spray on ultra-thin conductor of
electricity as well as many other applications for graphene:
(from Nanotrons website)
Protective Structural Materials (as Nanofillers and Nanocomposites)
Fuel (Cryogenic) Tanks
Engine and turbine components
Protective Elastomer components
Transparent Conductive Film
Organic Photovoltaic cells
Organic light emitting diodes
Sensors & Catalysts
Liquid Crystal Displays
Energy Storage and Electric Devices
E-papers & Conductive inks
Anti-microbial, Chemical, & Thermal
Air & water purification
Chemical and explosive detecting sensors
Thermal management and interfacial materials
Microbial detection and diagnosis devices
ACS Material is also working extensively with graphene.
ACS Material's graphene nanoplatelets can be used to increase tensil strength of basic materials, improve "stiffness, corrosion resistance, abrasion
resistance and anti-static electricity and lubricant properties."
so companies are already working with this product some of us have never heard of! Graphene alone could be responsible for major changes in the way we
live our lives!
Science and Anomalies of Graphene
... now wait a minute... I thought you said it was clear!
This is a picture of "graphene paper" from the University of Sydney - it is carbon grey, yes?
(discussed in ATS thread New Graphene material is Paper-Thin &10 Times Stronger Than Steel (amazing) by Anon72)
Scientists are discovering some VERY WEIRD things about graphene! It seems to be laden with hidden anomalies and characteristics we couldn't have
predicted. I can't seem to find the source but I've read that under various electrical fields graphene either reflects light or takes it in... meaning
it can be a mirror or an invisible sheet depending on how we treat it.
Graphene seems to just be a sheet of double-bonded carbon atoms and I guess we'd expect it would just be a strong sheet of non-reactive atoms... but
We've worked with materials made of only carbon atoms
before without such anomalies:
In 1947 graphene (not by that name) was postulated but expected to be impossible to create.
in 1985 something called "Bucky balls" (or Buckminsterfullerenes ) were created; they are a sphere of Carbon atoms double-bonded together. (see pic
Shortly after we created bucky tubes, or Carbon nanotubes, that were strong enough to hold a satelite in orbit and smaller than a human hair.
In 2004 Andre Geim and Konstantin Novoselov and their teams demonstrated that single layers of graphene could be isolated, resulting in the award of
the Nobel Prize for Physics in 2010!
Now that we've been working with graphene across the globe for a few years now we're finding a lot of anomalies, such as this one described in ATS
thread Graphene Bubbles have Bizarre magnetic properties, by Gentill Abdulla (source: Science Daily)
The bizarre magnetic affects include rapid vibration of the Carbon atoms that could speculatively be used in many applications such as particle
accelerators, scanning devices, and possibly even levitation!
also, one final link and the story that prompted this thread...
Graphene Gives Protection from Intense Laser Pulses
Scientists at the National University of Singapore (NUS) , DSO National Laboratories and University of Cambridge have jointly announced a new
world record in broadband non-linear optical absorption behavior using single-sheet graphene dispersions in a variety of heavy-atom solvents
and film matrices.
Could it be that graphene changes our vary existence!??
Imagine graphene ultra-light floating vehicles...
nano- size computer chips making our Cloud technology worldwide...
Medical devices that see inside you, and change things, at the atomic level...
As with any technology it can be used for good things and more nefarious things but graphene is surely something that will affect our lives in many
ways in the very near future!
