Aside from seeing the #cyclodextrin up and down on the surface, one curious case is when some of the glucose units twist and form this intermediate configuration. The molecular dynamics simulations (left) explains beautifully the "absence" of lobes in the experimental images.

Beautiful example of Pyrene vs Acepleiadylene from Michael Gottfried. Non-alternant structures show again that they like to be way closer to the surfaces, to the point of chemisorptive bond in the case of acepleiadylene. sciencedirect.com/science/articl…

nature.com/articles/s4146… I remember seeing PTCDA molecules working as antennas on surfaces in 2018 (Niklas also involved). Now, it is cool to see their electrostatic field enabling them to emit fluorescence light. Fascinating work Anna Roslawska and all (only tag I have!)

Getting closer to a molecular Aharonov-Bohm interferometer...Vitek et al show that a completely cycled ring of porphyrins could contain quantum behavior up to a length scale of 18 nm. Very cool.

Physics texts tell us particles come in only 2 types - fermions or bosons. Our Nature paper today shows other, thought-to-be forbidden, particles are possible. Why you should care & addressing a concern I’m sure some experts have: “this must be wrong!” (warning: mammoth thread)

The narration... unbelievably funny

Very nice to see this result from Campaña Group and MOR_Fun research group! I remember Federico Villalobos Romero visiting us back in the day in Olomouc trying a related precursor (an unlucky one though... sometimes it happens). This one just worked nice

Quite feverish and with cancelled flights, but still the dpg was decent enough. Thanks for the braves one staying till Friday mid-day

This paper is mind-blowing. I'll have to read it several times I think, msybe on holiday. It's one of those refreshing speculative ones.

These analog systems are always full of ingenuity 'how to embody mechanical computation into 3D printed objects, i.e., without electronic sensors, actuators, or controller'. The video in the thread is really cool.

Maybe the shortest introduction to the Ising model I have ever seen

Great read! Mass selection + landing energy control is crucial to avoid any fragments on surfaces that interrupt or hinder interesting reactions on surfaces. But also enables using gigantic precursors or biomolecules into surfaces. Maybe I'll show soon some examples of this...

Sometimes intuition is enough, but steric repulsion was hard to visualize for me. I used to eyeball it from simulations, and now it’s right there to see...cool work!

Congratulations to Harry Anderson Group (!) On surfaces, we have seen cyclocarbon rings created with clever tip-induced strategies (tldr: removing atoms from a precursor) Now…48 carbons stabilized with catenates in solution. phys.org/news/2025-08-c…

Imagine the potential N layered sandwiches of materials wildly differing in their electronic properties...

We found (theoretically) another case of F tunnel! Now, for the same price, including a fluorine halogen bond. "Fluorine Ping-Pong Tunnelling in Cages" New J. Chem. - Festschrift for Giuseppe Resnati doi.org/10.1039/D5NJ03…

Beautiful result
