I want all my holes filled with graphene

How do you create graphen?
i want some.

>"They used adhesive tape to repeatedly split graphite crystals into increasingly thinner pieces. The tape with attached optically transparent flakes was dissolved in acetone, and, after a few further steps, the flakes including monolayers were sedimented on a silicon wafer. Individual atomic planes were then hunted in an optical microscope."

well fuck.

>petabit and exabit transmission speeds

Have any of these actually been implemented? I've read so many articles over the years about too good to be true technologies that never see the light of day.

I am... not... impressed.

Currently drafting my third year project proposal. Synthesis of graphene for use as a dessication device or filter.

Yeah, this stuff is awesome but REALLY awkward to get your hands on. Most sheets about about 50 nm accross.

Can link some of my online sources for you to browse through if you want, about as interesting as measuring the change the change in visocity of colloidal pigments over time.

All of them are in the HEY LOOK WE CAN GET THIS AFFECT! phase.

The theory is there, and the laboratory scale experiments demonstrate the theory correct.

But it is not a commercially viable product yet.

Fun fact using the math from the graphene solar panels concept.

Coat all the windows of a skyscraper with graphene and you could power the whole building with the generated power. Of course this does not take into account getting that power to where it is needed.

Meh. I want my perpetual motion machine!

>SAN RAFAEL, Calif., Nov. 1, 2011 /PRNewswire/ -- Graphene Technologies (GT) announced a significant milestone in its mission to manufacture high quality graphene at industrial scale and pricing. On October 20, the first of a series of patent applications filed by the company on its novel technology for the production of graphene and other nanomaterials was published. This application is an important part of the company's IP holdings and reflects years of scientific work aimed at commercial use of its process to synthesize high quality graphene materials.

>"We are very pleased to have completed several patent applications and to see the first of these published. This is an important step for us," said Jon Myers, GT Co-Founder and CEO. "We are singularly focused on further developing our advanced, scalable process to produce industrial quantities of single to few layer graphene materials."

>The Company has discovered and developed a novel process in which carbon dioxide is used as the primary feedstock for graphene production. The process exploits the highly exothermic reaction between certain alkaline earth metals, including magnesium, and carbon bearing gases, including carbon dioxide, to generate graphene. Graphene is a very promising nanomaterial with potential applications in semiconductors, electronics, displays, energy storage and transmission, photovoltaics, advanced plastics and structural materials.

>"The ability to make advanced materials through a combination of widely available minerals with a greenhouse gas is a significant achievement," continued Myers. "Our scientists have produced the highest quality single and multiple layer graphene available, while demonstrating the potential for achieving the lowest production cost possible for this material."

It is really easy to make really small sheets of graphene, getting over 50nm takes stupid amounts of time and effort using silica substrates.

That would go against the known laws of physics.
A new material won't let you have one - a new theory will.
>>4508278
Then you don't really understand what's being said.
>>4508275
No, graphene has only recently come into the public eye. Research into its properties won the 2010 physics Nobel prize.

Every other time something was claimed to have so many outstanding properties it turned out to either be hype or an outright scam. We'll see in a few years.

>>4508430
Well they already won the nobel prize. I think it's legit.

>>4508438
Just winning a Nobel prize doesn't mean it's legit. Take Fermi for example, he was awarded the prize for, among other things, discovering two elements which don't actually exist.

>>4508457
That was over 70 years ago. Research has become much more demanding and accurate. If it was a scam it would come from one institute. But those results come from dozens of different institutes all over the world.

As always, Carbon confirmed for best element.

can't wait for graphene solar cells.

Awesome. Thanks.

>>4508638
This just makes me more sceptic
>It revolutionizes EVERYTHING EVER
>no explanation whatsoever
>"You can do X with it!" out of the ass everywhere
>we can save billions of dollars
>Unspeakably abstract and unfounded medical assumptions
>how have I never ever seen a single thing that uses graphene

I want to believe

>>4508746
Yep, friend of mine has sent me this link, and I just couldn't find the right words to explain to her, that this is complete bullshit.

>>4508760
Oh god I just came to the part where it is implied that you can make LOLINVISIBILTYCLOAK using the power of GRAPHENE!

I hate it when people jerk so much over themselves they can't see anything they don't want to hear.

There is probably good reason this isn't a youtube video where people can commentate on.

>>4508638
I just watched 5 minutes of it. Graphene production/attributes were mentioned for about 10 seconds. Then there were 4 minutes of talk about how you could use it to make your iphone better.

This is just as bad and unscientific as the propaganda videos greenpeace and other backwards organisations create.

>>4508394
The green text never mentions the size of the sheets synthesised.

>>4508301
It's possible to make 75 cm sheets now. I was thinking of making some earlier but the largest I'd hope to get would be 1 mm or so

>>4508809
well then, can you tell us what of the video in
>>4508638
Isn't pure wishful thinking/talking out of the ass?

>>4508249
how fast is that?
