[quote]Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the National University of Singapore have attested that the thermal conductivity of graphene diverges with the size of the samples. This discovery challenges the fundamental laws of heat conduction for extended materials.
Davide Donadio, head of a Max Planck Research Group at the MPI-P, and his partner from Singapore were able to predict this phenomenon with computer simulations and to verify it in experiments. Their research and their results have now been presented in the scientific journal Nature Communications.
"We recognized mechanisms of heat transfer that actually contradict Fourier's law in the micrometer scale. Now all the previous experimental measurements of the thermal conductivity of graphene need to be reinterpreted. The very concept of thermal conductivity as an intrinsic property does not hold for graphene, at least for patches as large as several micrometers", says Davide Donadio.

Optimum cooling for nanoelectronics
In the micro- and nano-electronics, heat is the limiting factor for smaller and more efficient components. Therefore, materials with virtually unlimited thermal conductivity hold an enormous potential for this kind of applications. Materials with outstanding electronic properties that are self-cooling too, as graphene might be, are the dream of every electronics engineer.

The researchers who are working with graphene must feel the same way as the people who first worked with electricity. It seems like every day there's a new unexpected use for this stuff, and the most incredible thing about it, to me at least, is that this is just one material in a whole array of possible materials. I encourage you all to make graphene and just fuck with it because you never know what amazing thing you could discover by just mixing shit together. (mostly a joke, but hey anything could happen)
"I encourage you all to make graphene and just fuck with it.."
soo can i make a fleshlight- uh i mean phallus wallet without the need for any lubricant and a condenser, without creating much friction and heat?

I'd rather not discover cancer.
I remember some dumbass youtube talk show host was blabbering on about the endless possibilities of graphene
except he was fucking wrong
He had the strangest idea that graphene was biodegradable because it was made of carbon, and suggested that you could use it to fertilize your garden or some shit

That's pretty damn useful.
Imagine not needing water based cooling systems in cars and such.
So when are we actually going to see a product in the wild using this stuff? There's so many 'discoveries' of all the 'amazing' and 'wonderful' things this shit can apparently do yet NOTHING on the market that actually applies a single thing they've said.
How about instead of poking it for new things it can do we put this damned thing to work? If it's even 10% as amazing as the scientific media claims it is there should be a hundred products on store shelves using this stuff in some manner. Get to it!
I think the reason it hasn't been but to work yet is because the current way of making it en mass is economically infeasible. The discovery we need is in mass production of a usable product.

I think you will see the first solar panels that use graphene for sale pretty damn soon.

it was like 80 fucking years since they were playing around with electricity in science institutes for shits and giggles and when it was actually used commercially
fuck graphine, you broke the laws of thermodynamics
why are you so awesome??

im a chemical engineering major, ya there's a bit of a huge step between the lab table and the shelf, it involves massively scaling up which never works as intended and lots of pipes and other expensive machinery

Those things take time. Even developing a product with known technology can take months or years. Unknown technology must be characterized first, we have to understand how it works. And then we need to figure out how we can use those effects to our advantage.
It's kind of like finding out what tools you need to create a table out of wood, and then trying to do it yourself. You have to figure out how the tools work before you can use them.
What if graphene was the universe's debug tool and was never meant to be used, and when the (m/g)ods discover us fiddling with it, they turn off chemistry

Wow you mean the media blows shit out of proportion? Who fucking knew?
Graphene confuses and excites me

What does any of this have to do with heat conduction in graphene?

it takes ages for things to become feasible
the romans had steam engines, the medieval chinese had guns, people had internal combustion engines in the 18th century, flying machines in the 19th, and radar existed before the first world war
of course, none of this really mattered because they never even got to apply it on a meaningful scale until methods of manufacturing them and using them safely and reliably were developed
not to mention the demand had to exist, and the specialists who made and maintained these things
Graphene computers please
technically you could use this for colder overclocking right?
delete this post mods
automerge glithed

In theory, yes.

I hope we get cold running computers that you could theoretically overclock massively
imagine that on a quantum computer

What the fuck is research and development? What asshole decided that it was a good idea to test new discoveries and inventions for years to determine their uses and if they are safe at all. Back in [i]my[/i] day we let asbestos just go right to market because it has helped millions of people. Sure pal, whatever. I'd rather not see graphene clothing and then discover the next week that the world's best selling boxers cause your dick to rot off.

I'll take two
I'd fap to graphene

Facepunch is unaffected.
[QUOTE=Satane;44799598]I wonder if graphene is gonna be the next asbestos.[/QUOTE] Its already pretty much acknowledged that it shouldnt be breathed in, we're not going to start fucking putting it in clothes and masks and insulation. It's too useful not to be used. We're not doing away with it like we did with asbestos. So no.

Just slap a coating of epoxy or resin over it to layer it, make sure that no flakes manage to just start floating around.

The only reason we have commercially plentiful and ubiquitous electricity is because Farraday kept experimenting off of a statement he took to heart after Davy said it as a sarcastic joke until he got something practical off of it.
