Looking at the EG, I'm not sure if a simple conversion of 'graphene' to 'carbyne' would necessarily be accurate.

If you're sure that a straight substitution is all that's needed, I can certainly do that. However, if you'd like to look the article over and modify it to better fit the different properties of carbyne vs graphene (or even generate a separate article while modifying the graphene article to acknowledge the existence of carbyne or combine them or whatever), then I can expedite the replacement or addition.
Just let me know what you prefer.
Thanks!

In light of this, it's probably best to hold off until more conclusive evidence (such as unambiguous manufacture of carbyne) presents itself before editing the entry.
No problem

If things change later, we can always tweak it then.
