I don't have sufficient reputation to comment, and this doesn't warrant a separate answer. orthocresol's answer covers it.
But here's the origin of the image the question asker and a number of news outlets have used:
https://www.flickr.com/photos/ibm_research_zurich/albums/72157710174720097

It is, in fact, an artistic interpretation; the album also contains an overlay that illustrates that perceived vertices do not map to atomic nuclei.

A cyclo[n]carbon is a chemical compound consisting solely of an n number of carbon atoms covalently linked in a ring. Since the compound is composed only of carbon atoms, it is considered an allotrope of carbon. Possible bonding patterns include all double bonds (a cyclic cumulene) or alternating single bonds and triple bonds (a cyclic polyyne). == Cyclo[6]carbon == The (hypothetical) six-carbon member of this family (C6) is also called benzotriyne. There have been unsuccessful attempts to synthesize it. == Cyclo[18]carbon == The smallest cyclo[n]carbon predicted to be thermodynamically stable...

Q: Is there a commercial liquid with refractive index greater than n=2?

Persian_GulfFor an application I need a commercial, transparent liquid with refractive index n>2, is there this kind of liquid available? On the web only n=1.81 is routine. The second question is, what's the chemical composition of this?

Q: A systematic way to find scaled/rotated hexagonal lattices commensurate with a unit hexagonal lattice?

uhohWood's notation is used to reference the relationship between two 2D lattices when the angle between the two unit vectors $(a_1, a_2)$ of one lattice is the same as the angle between the unit vectors $(b_1, b_2)$ of the other lattice. It's written with the ratios of the corresponding unit vectors...

Q: Atmospheric methane to carbon

TschallackaI read an article by popsci that talked about huge fans forcing methane over a catalyst. Now that got me wondering, can't we produce hydroxyl radicals with powerfull uv lasers blasting the sky, creating more hydroxyl radicals to break down the methane. Would this be effective enough to help cre...

Q: Mixtures readily oxidzing organic matter

Francis L.Are there other mixtures than piranha solution with similiar or better ability to completely and readily oxidize organic matter? Perhaps peracetic/performic acid?

Q: Is "stainless" a bulk or a surface property of stainless steel?

SparklerIn particular, if I cut a block of stainless steel in half, would the newly formed faces be stainless as well?

Q: What is "super" in superphosphate?

Nilay GhoshThis question is inspired from a previous question(marked unclear). I don't know about the context of that question but I was intrigued by a statement in that question: Superphosphate is used instead of just phosphate because superphosphate is a compound whereas phosphate is an ion. Now, ...
