Graphene


Ever heard the name? Seen on the news or web? The miracle material?

Basically set to become the material that will change just about everything. Its discovery had been made back in 2004.

Won't bore you with the details other than it won a some prizes here and there and is carbon sheet that is one atom thick and amazingly strong, many times stronger than steel.

.........I'll say that again a sheet you can pick up and handle one atom thick.

Its starting to make inroads to all sorts of applications and graphene powder has been used in tyres which renders them gas proof, even hydrogen cannot penetrate  graphene. Interestingly it could make tyres effectively virtually puncture proof in time, apparently it would take an elephant standing on a pencil to pierce a sheet of graphene as thick as cling film Yeah! take that Blackthorns!!!

Another thing is its very transparent and can be made water repellant so goggles lens would never fog, scratch, or break. Troops have been issued with googles that can withstand a shotgun blast from 16 feet away, the material is "secret", but I would guess its Graphene.

So strong is Graphene it makes carbon fibre look like lead in comparision. Paper thin cars?

Compared to steel, the prepared graphene paper (GP) is six times lighter, five to six times lower density, two times harder with 10 times higher tensile strength, and 13 times higher bending rigidity.

A metre square sheet of Graphene could be made into a hammock, support a 4 kilo cat and weigh no more than one cats whisker, and be almost invisible.

When you look into the multitude of uses and properties of this material its mind boggling, how about an Iphone you can roll up and stick behind your ear? Already Samsung have made a flexible screen using it, want more more? Lubricant free engines? Suits you sir!

Google it!

Do you believe in miracles from Manchester? biggrin

On the subject of futurology, I gave up my bells and whisteles 'phones when I stopped being a courier.  Now I just use a 10 quid pay as you go Nokia and it is brilliant.  For a start I only have to charge it once a week.  When the battery does go flat it is even better, it doesn't make any noise or disturb me at all.

Technology is great but going back 10 years is cheaper and less hassle.

 Why stop at 10, lets do a proper job and go back to the age of Cast Iron and Steam, an age when Britain ruled the World, and when rioters and looters would have been read the riot act statement and then shot where they stood, and then the police would go round to the dead miscreants house and take payment for the ammunition they had just used

Who said all things have improved in the modern age, go on cameron bring back the birch and hanging

I meant mobile phones but I suspected you'd reply. biggrin

Also because CRs weren't introduced until the 70s. wink

Cool stuff;

 

Graphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice.[1] The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm,[2] who described single-layer carbon foils in 1962.[3] Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

The carbon-carbon bond length in graphene is about 0.142 nanometers.[4] Graphene sheets stack to form graphite with an interplanar spacing of 0.335 nm, which means that a stack of three million sheets would be only one millimeter thick. Graphene is the basic structural element of some carbon allotropes including graphite, charcoal, carbon nanotubes and fullerenes. It can also be considered as an indefinitely large aromatic molecule, the limiting case of the family of flat polycyclic aromatic hydrocarbons.

The Nobel Prize in Physics for 2010 was awarded to Andre Geim and Konstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene".[5]

 A little before my time, but I did have a NSU sickly, as for mobile phones arghhh you cant even go for a crepe in peace

I love my latest smart phone - HTC Desire Z running Android 'Gingerbread'biggrin

You can stuff your old Nokia's with their light weight and easy to read screen in direct sun light and their long battery life and easy of use, oh....cry

Still love the new technology though, I said I wouldn't upgrade anymore past my last HTC but sure enough I was tempted by the flashy new ones.

 

Long live Technology!

Gah! I only mentioned mobile fones briefly and you are talking about Nokia an' andriods and CRFs

Talk about drifting of topo biggrin

Btw is that the new updated CRF ? winkbiggrin

Looks dandy to me although I think the front forks look a little flimsy, no front disc but a rear is a little weird too.

That's one hell of a rear sprocket - must at least 100 teeth.

That would explain why it's so light!

Incredible how a plastic body kit can disguise the true form.

Makes you wonder whats lurking beneath an orange things plastic covering?

 In my experience lots of expensive hi maintenance stuff that wears out quickly.

That said if mobile phones hadn't evolved into the hi tech stuff we had today we would all still lugging around those huge brick like efforts that look like a WW2 military radio.

That said at least they worked as a phone which is more than my missus desire z did after its "gingerbread" update. Still at least she can still play  bubbleburst on it no

Btw I fixed it, just feed it through the garden shredder. sorted

An imense feat of engineering that produces (in my view) one of the best bikes available today! Well,....... someone had to bite!
