    How to Make Large Graphene Sheets?

    From the paper in question. "...the copper was etched with ammonium persulfate instead of FeCl3, and polydimethylsiloxane (PDMS) was used to support the graphene during copper etching and to drystamp it onto the substrate without baking" I'm not sure why ammonium persulfate would be a better...

    How to Make Large Graphene Sheets?

    Awesome! I wasn't sure what level of understanding you had, so I went with a generic reply. I'm definitely a newbie on these forums, but I'm pretty familiar with graphene. The LightScribe method you're talking about is a pretty cool DYI method, but from my understanding, reduction of GO...

    Carbon nanotube exoskeleton

    1. I'm not sure how to answer that. 2. Depends on what you consider a body-suit. If you mean covering every area of the human body by a single layer of nanotubes, yes. But you would want much more than a single layer of CNTs for armor. 3. You're misunderstanding the quote there. It's said when...

    How to Make Large Graphene Sheets?

    You're basically asking how to find the holy grail of graphene. This has been the main question since 2004, the question that has been on the mind of many graphene researchers like myself. Chemical vapor deposition (CVD) is currently the popular method for large area graphene growth. This is...

    The stabbing resistance of graphene:

    Link to Columbia professor James Hone saying this. That said, there are a number of reasons why this quote is misleading. 1: Stacking layers of graphene leads to the formation of graphite. Unless you can find a way to stack graphene without having individual sheets bond to each other, the...
