Scientists Produce Graphene 100 Times Cheaper Than Ever Before (gizmag.com) 77

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."

    I hate it when people misuse language to describe math.

    What does "100 times more cheaply" mean?

      It says you get 100 times as much for the same money. Don't you understand any English?
    • What does "100 times more cheaply" mean?

      Everyone fluent in English knows exactly what it means. English is a natural language, not an expression of formal logic. Stop being a pedantic Aspie.

        Stop being a pedantic Aspie.

        "Aspie" is not even a word. There is no such word. Seriously, what does that even mean?

        • "Aspie" is an abbreviation that originated as an internally friendly way of people with Asperger's Syndrome of self identifying as part of a group. It was supposed to be a way of these people to feel a sense of belonging in what can seem like a foreign world to them.

          Although in this case it is being hijacked to be used as a pejorative because this group happens to be more detail focused (the same way people hijacked the words queer and gay from the LGBT community to use as insults).

          New words are invented al

          • in this case it is being hijacked to be used as a pejorative

            It is NOT being hijacked. I am at least as much of an Aspie as the GPP. Therefore, as a member of the group, I have the right to use the word.

      • > English is a natural language,

        From Wikipedia:

        In 1990, in the Usenet group rec.arts.sf-lovers, Nicoll wrote the following epigram on the English language:

        The problem with defending the purity of the English language is that English is about as pure as a cribhouse whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and riffle their pockets for new vocabulary

    • I take it to mean 2 orders of magnitude less costly. I do understand how unnatural it is for people like us, who see "times" as an operator, to see it's use in such a context. And while I'm all for clear communication, I stopped looking for it from English a very long time ago. Clarify all you like, but stay away from my homonyms!
    • You know what it means. I know what it means. Everyone knows what it means.

      If you insist on a rigorous mathematical definition, it's very simple. "Cheapness" is simply the inverse of "costliness." So if something is 100 times cheaper, it's 100 times less costly. If something originally cost $100, it now costs $1. Capiche?

      100 times more cheap. Take the price, sivide by 100. Is that really so difficult?
    • by Dog-Cow ( 21281 )

      It's OK. You're 100 times more stupid than a toaster oven.

    • This is perfectly understandable and logical - it means 100th the price. ironically there are lots of examples of misuse of maths about, e.g.:

      "divided by half" - a bastard of "divided by two" and "multiplied by half", which actually means the exact opposite: multiplied by two.

      "a half less" - a chimera of "half as much" and "half of", which again means the opposite.

      "0.01 cents" - a mongrel of "one cent" or "$0.01", instead giving a price 100 times cheaper.

      So let's save our outrage for the next time som

    "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?

    • ~$1 per square meter for "normal" copper.
      +$125 per square meter for "high grade" copper. Which also needs to be processed in order to use it.
      If I interpret the article correctly, they are using the shaped high grade copper to create something like a cast. Casting graphene apparently eliminates the cost of some chemicals, and increases yield(not sure if in failure rate or in speed). Chemical vapour deposition(CDV) is stilled used, but its less messy than the traditional method.

      That said, I still want a fucki

    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.

    • by mark-t ( 151149 )
      This is just a guess, but I'd imagine that it's probably because they get it from a source that accepts USD.
    • by Sique ( 173459 )
      Because they have looked up the retail prices in dollar to make it more easy for non-UK-residents?

      Well, coppers in Glasgow don't wear the traditional police helmets, so I suppose you could flatten them out more and get more square meters per copper.

      What do you mean wrong type of copper?....

      Because copper, like any other internationally traded commodity, is priced in dollars. Also, people almost anywhere in the world know what their local currency is worth in dollars, so they can do the conversion in their head. Far fewer are familiar with pounds. So if you are writing an article for an international audience, you use dollars.

  • 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?

      It is more of an analogy. All of these are built up in 3D but fullerene is called 0D as it is confined in all 3 dimensions; nanotubes are confined in 2D leading to a "1D material" and graphene is confined in a single dimension leading to a "2D material".
