Some graphene facts that I&#x27;ve found after a few minutes of research:<p>- One million times thinner than paper, one atom thick, it&#x27;s considered a 2D material. <a href="http://www.chemistryviews.org/details/ezine/4976821/Is_Graphene_Really_a_2D_Material.html" rel="nofollow">http:&#x2F;&#x2F;www.chemistryviews.org&#x2F;details&#x2F;ezine&#x2F;4976821&#x2F;Is_Graph...</a><p>- Strongest material, stronger than diamond. <a href="http://engineering.columbia.edu/even-defects-graphene-strongest-material-world" rel="nofollow">http:&#x2F;&#x2F;engineering.columbia.edu&#x2F;even-defects-graphene-strong...</a><p>- Scotch tape was used to create a piece of graphene only 10 layers thick (I&#x27;m guessing that means ~10 atoms thick? wow)<p>- Moves electrons ~200 times faster than silicon: <a href="http://www.samsungvillage.com/blog/2012/05/18/samsungblog-samsung-electronics-presents-a-new-graphene-device-structure/" rel="nofollow">http:&#x2F;&#x2F;www.samsungvillage.com&#x2F;blog&#x2F;2012&#x2F;05&#x2F;18&#x2F;samsungblog-sa...</a><p>- Transparent, only absorbs 2.3% of light. <a href="http://arxiv.org/pdf/1201.3071.pdf" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1201.3071.pdf</a><p>- Can&#x27;t switch flow of electricity off? <a href="https://gigaom.com/2013/04/19/you-can-pluck-graphene-from-thin-air-but-then-what/" rel="nofollow">https:&#x2F;&#x2F;gigaom.com&#x2F;2013&#x2F;04&#x2F;19&#x2F;you-can-pluck-graphene-from-th...</a><p>- Can repair itself if you dump carbon atoms on the hole, they snap into place. <a href="http://arxiv.org/abs/1207.1487" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1207.1487</a><p><a href="http://en.wikipedia.org/wiki/Graphene" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Graphene</a>

Graphene is pretty cool stuff but just flakes of it are not as useful as sheets are. That said, for experimental purposes this may be an excellent laboratory technique for acquiring samples. Not sure why the anode needs to be platinum though. It seems like any conductor would work there. Given that a common &quot;D&quot; sized Dry Cell (aka a non-alkaline battery) will give you a graphite rod (the center core is pure graphite) everything but the platinum should be available off the shelf. If it really <i>does</i> need a platinum anode you&#x27;d have to raid a catalytic converter for that.

If anyone is interested in making graphene yourself, Robert Murray Smith, a chemist in the UK with an amazing Youtube channel, posts some tutorial videos on making graphene at home. He describes this specific method here: <a href="http://youtu.be/QMp-RP8DcOc" rel="nofollow">http:&#x2F;&#x2F;youtu.be&#x2F;QMp-RP8DcOc</a>

How likely is to make graphene in your own house? Expensive? Dangerous? Requiere high skillset?<p>I&#x27;m very naive about this, so in my wild imagination: What will need to happend to have a &quot;Rasperry&#x2F;Arduino&quot; set for graphene?

Is graphene a long term risk (like say plastic...or even asbestos)? The benefits are obvious and we&#x27;ll clearly mass produce it sooner or later, but is this something we can safely throw at all kinds of problems?
