I tried to edit this question, though I didn't, but that's not the point here. And, just as Pythagoras sensed that a formula is needed for the base of geometry of right-angled triangle, I sensed that there is a need for a tag here.
I looked for something like it but didn't find any results; the organic-chemistry is way too broad for it, synthesis tag and polymers tag are kind of 'out of the league' and nanotechnology tag could be better for describing what I'm about to suggest.
There is this tag: "Fullerenes", which can be turned into something like "Carbon-allotropes" or something more useful. Yes, I'm looking for a tag that contains the allotropes for C, other than diamond or graphite, that were first synthesized in a lab and were 'artificial', like fullerenes, graphene and nano-tubes.(However, we know that fullerenes do exist in the space, naturally.)
About the number of questions, doing a search with the "Graphene" keyword leads to more than 40 related questions, so that wouldn't be a problem. Sooo,
- Is there a specific reason that this especial tag doesn't exist?
- If we don't want or need to make it, why?
- If you think there should be such a tag, what name would you have chosen for it? Because I didn't reach any sensible names.
