Particularly interested in the work of Cumings and Zettl, and of the Stevens and Nguyen groups mentioned in the second and third paragraphs of the section on nanowelding, I believe you've saved me a lot of time and I appreciate it. Are you aware of any images depicting the types of carbon bonds (possibly at high and low temps and/or under stress?) that I might also have a look at? /R A useful orientation, Phillip, thank you.

A double carbon bond means a "double bond", which is kind of like a double-strength bond, between two carbon atoms. Graphene bonds are "aromatic", which in this case is sort of in between single and double. You can learn more about this by starting with the Wikipedia entry on graphene. A good high school chemistry text should explain these matters more simply than Wikipedia does, I think.

What is the difference between a carbon-carbon bond and a double carbon bond? Are either relevant to the production and use of graphene? /R You’re the best.

Is this a good place for me to be asking simple questions about carbon-carbon bonds? Too often the more I think I understand, the more confusing it all gets. Maybe some of your other readers can point me in useful directions? Thanks to all, /R Hello Christine.
