Scientists Produce Graphene 100 Times Cheaper Than Ever Before (gizmag.com)
Zothecula writes that researchers at the University of Glasgow have found a way to produce large sheets of graphene 100 times more cheaply than previous methods. Gizmag reports: "Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene using the same type of cheap copper used to manufacture lithium-ion batteries."
This is how you make really nice chopped steak. Feed the graphine to cows, they eat it, the sharp edges of the graphine cuts them up snippity snip snip. 5 minutes later, the cow drops dead into a heap of chopped meat.
When did copper get cheap? Copper has been crazy expensive for 10 years now.
I hate it when people misuse language to describe math.
What does "100 times more cheaply" mean?
"The commercially-available copper we used in our process retails for around one dollar per square meter, compared to around $115 for a similar amount of the copper currently used in graphene production," said Dr Dahiya, of the University of Glasgow's School of Engineering."
How much was the price of copper, the total price of the production?
Researchers at the University of Glasgow claim that they can create graphene using cheaper copper. They claim that the copper they use costs $1 per square meter, whereas previous production methods require a copper that retails for $115 per square meter.
Note: I have no idea why researchers at the University of Glasgow price their materials in dollars.
Cheaper than scotch tape and pencils??
I'm trying to figure out if this actually means anything to companies planning to mass produce graphene.
UoM proved that you can use any thickness of copper so long as it is smooth. I don't see why factories would be negligent to that detail.
The graphene sheets still need to be formed using a CVD process, which isn't mass production friendly.
What I do find interesting is the copper foil is considered a "superior substrate".

You're a one-trick pony, haven't you got anything else?
I would have gone for "one trick heifer", but other than that I agree...

More gooder.
now it's only $1,000,000,000,000/gram. practically free.
Sleep your way to a whiter smile...date a dentist!
Great! Large sheets of graphine! How big is a large sheet of graphine?
Great! "Large" sheets of graphene! How big is a "large" sheet of graphene?
Check your numbers. SpaceX is producing Graphene in quantity,
you write a lot of words but the only meaning I'm gleaning is "I am a unhappy cow. Moooo! Mooooo! I'm jealous of happy cows. MOOOOOOOOO!!!!"
Despite a fairly straightforward critique of his cow posts, the message you got from that text is that I am unhappy? I suppose some people can only read what they want out of text, that does explain a lot about how the media operates!
You are like rock, rock says nothing, never changes. Rock.
Oh, yeah, give him attention, that'll stop him.
From the article : "As a two-dimensional crystal of carbon atoms, graphene is a basic building block of many carbon derivatives such as zero dimensional fullerene, one dimensional carbon nanotubes, and three dimensional graphite. "
How can a tube be one dimensional?
The global community of office tape dispensers and tape rolls were relieved to hear of this invention.
How much does 'ever before' cost?
