Aren't graphite and graphene different structurally?

• fspeech 4y ago
  From the article: "Graphite, the common form of crystalline carbon (the rarer one being diamond) is, in essence, a lot of layers of graphene piled on top of one another." So when you write by rubbing graphite on paper you leave behind graphene on paper.

    Makes sense. Although I would be surprised if pure carbon, of all elements, had a negative effect on our ability to live ROFL.

      Drinking too much water can cause a fatal electrolyte imbalance in your blood. Breathing too pure of oxygen will seriously, perhaps fatally, damage your lungs. Many metals are simultaneously important in trace amounts and debilitating or fatal in larger (albeit still small) quantities. That's just for things that you are supposed to do, only too much of. Graphene is not useful or an important part of your body's functions; doing things you aren't even supposed to be doing with it (breathing it in, for example) can only have a negative effect. Speaking of pure carbon, carbon nanotubes are known to cause lung tumors.

  Graphene is a single or very few layers of Graphite

  We can get graphene by literally peeling it off graphite using a scotch tape. > That's where Andre Geim and Konstantin Novoselov came in. They took a hunk of graphite and used Scotch tape to peel off layer after layer after layer. Geim and Novoselov then analyzed what they had left, and found graphene. For their discovery – which was published in 2004 – they were awarded the 2010 Nobel Prize in Physics. https://science.osti.gov/Science-Features/News-Archive/Featured-Articles/2011/03-25-11 https://science.osti.gov/Science-Features/News-Archive/Featu...
