Topological classification of cycloadditions occurring on-surface and in the solid-state Communications Chemistry, Published online: 03 December 2025; doi:10.1038/s42004-025-01701-0Understanding cycloaddition mechanisms is beneficial for the creation of extended carbon nanostructures, yet traditional models often overlook symmetry-based mechanistic effects. Here, the authors employ topological classifiers to identify symmetry-forbidden pathways in polycyclic aromatic azomethine ylide cycloadditions, revealing that topologically-allowed endothermic reactions can guide nanographene engineering.

We‘ve been there & welcome to TipshapingSky @newhorizons-stm.bsky.social ! Here’s a useful link: go.bsky.app/LKyQJm7

Oh yes what happened with the molecular machine online poll? Did we miss the results?

hmm the Bluesky preview shows a gif but its gone when posted, here’s a link upload.wikimedia.org/wikipedia/co...

Aromaticity Reversal Induced by Vibrations in Cyclo[16]carbon Aromaticity is typically regarded as an intrinsic property of a molecule, correlated with electron delocalization, stability, and other properties. Small variations in the molecular geometry usually result in small changes in aromaticity, in line with Hammond’s postulate. For example, introducing bond-length alternation in benzene and square cyclobutadiene by modulating the geometry along the Kekulé vibration gradually decreases the magnitude of their ring currents, making them less aromatic and less antiaromatic, respectively. A sign change in the ring current, corresponding to a reversal of aromaticity, typically requires a gross perturbation such as electronic excitation, addition or removal of two electrons, or a dramatic change in the molecular geometry. Here, we use multireference calculations to show how movement along the Kekulé vibration, which controls bond-length alternation, induces a sudden reversal in the ring current of cyclo[16]carbon, C16. This reversal occurs when the two orthogonal π systems of C16 sustain opposing currents. These results are rationalized by a Hückel model which includes bond-length alternation, and which is combined with a minimal model accounting for orbital contributions to the ring current. Finally, we successfully describe the electronic structure of C16 with a “divide-and-conquer” approach suitable for execution on a quantum computer.

In science the former might be considered more professional? "I am running 7 min late“ accurate, succinct, specific, honest? ✅ "Unf. my faculties were overtaken…" incompetence, vagueness, pot. misleading? ❌

On-surface synthesis and characterization of polyynic carbon chains A carbon chain with ∼120 atoms has been synthesized on the surface and characterized by bond-resolved scanning probe microscopy.

There are interesting realizations on surfaces e.g. academic.oup.com/nsr/article/...

A ultra-high vacuum lab featuring a shiny metal chamber with a photoemission electron microscope coupled to a 4 K scanning probe microscopy. The photograph also depicts a monitor which reads "FAIR Automated Surface Lab" and two panels, the lhs panel contains scanning probe spectroscopy and scanning tunneling spectroscopy HDF5 datasets being uploaded in the local lab NOMAD Oasis. The rhs panel is running a temperature measurement protocol for the sample.

Exciting, is there a 🦋 Automation Starter Pack? Our progress at @fairmat.bsky.social from the #on-surface synthesis #UHV side has been focused on #FAIRAutomation: autointerfacing with #NOMAD & #NOMADcamels, defining every 'bolt and nut' in #NeXuS & running LLMs–We hope to achieve autonomy by 2026🤞

A short teaser of our upcoming book preprint #Gestaltungsmetrik with art historian Horst Bredekamp wherein we attempt to define #holonomy in art, to imagine pot. underlying metric spaces. Thank you so much for the collab. on ribbon-based geodesics @alisonmartin57.bsky.social !

In the group we avoid referring to “AI” for this reason, as it’s more of a trademark vs. a technical term. A naive question would be rel. to evidence that the brain does not encode in LLM-like vector spaces, since most of the universe can be so modelled. Disclaimer we still need to read your book :)

Thank you MK, for being an inspiring mentor and supporting my applications. I would've loved to have more opportunities to discuss—alas, time goes by unjustly fast. My condolences, dear Marci and family.

The more spin chains the merrier! 🎉
