Without having actually ever done any fullerene chemistry, I feel I'm learning a lot! Paper models of C60 (top), C70 (right) and C80 - the Ih one (left).

Just over 22 years ago I delivered the big one. Now here he is delivering ducklings at Easter.
Hatched about an hour ago. The question is duck or drake?
Much excitement in my household today. And well timed by the new addition, it being Easter Sunday.

Oh no ๐ฎ!
I'm very happy with the idea of unit pricing. It was just that in this store you could buy PritStick (which barely holds two bits of paper together) or super glue! There's no crossover in their use! ๐
Joe, that's exactly right.
๐ I inherited mineral collection some years ago. I've put the pitchblende in its own special lead lined box!
Yes. It's fine. A really good Geiger counter will be able to show you, it is only very slightly more radioactive than the background radiation that we all experience every day!
Found this tiny piece of uranium glass on the beach. The amazing green fluorescence under the blacklight is unrelated to its radioactivity. It is caused by an electronic transition in the linear uranyl [O=U=O]2+ group; the most common structural feature of uranium in it highest oxidation state. ๐งช
Monoclinic?
(C70-D5h(6))[6,5]Fullerene aka rugbyballene!
Two decorated paper polyhedra, representing the structure of the fullerene C70.
These aren't Easter eggs. Testing different construction sequences and decorations on C-70 fullerene models. Black for the bonds, green for the pentagons.

Local store getting ready for new UK legislation on unit pricing.
Reminds me of being a crystallographer, when the computer returns a calculated density of x megagrams per cubic meter. I'd get stuck trying to imagine a cubic meter sized crystal!
What would you fix with a kilo of cyanoacrylate?
๐๐ it's just my phone, in a poorly lit room, quite late at night! The only edit is some cropping.
Exploring different, but simple ways of using paper to model chemical structures. This is C70 fullerene. It has a significantly larger interior cavity than C60, and an axial D5h point symmetry.

It's a very rough model of C70, if carbon atoms are placed on every corner. #SciArt #Papercraft
I'm quite confident I have the right components; just need the glue now!
Congratulations Michael. Agree about the paperwork.
Five white star-like paper polyhedra.
Enjoyed making these. The five Mรถbius deltahedra. Non-convex, acoptic, face-transitive polyhedra made from equilateral triangles.
Each edge of each triangle lies on a mirror plane. They have the same #symmetry as the Platonic solids, and are related to triangular tessellations on a sphere. ๐งช #SciArt
A box of convex deltahedra, printed with a decoration that gives the impression of atoms at the corners.

Trying to find "good" nets.
While there are 2 distinct nets for the tetrahedron, apparently there are 43380 for the icosahedron!
It seems easier to assemble nets that wrap, than more condensed variants. ๐งช #SciArt #iteachchem
๐ I might be selling pre-cut kits by then!
Slightly squiffy 3D build from paper loops.
This bipartite network is a model of the unusual niobium monoxide (NbO) structure (NB purple, O yellow!). The structure can be considered as a 1/4 depleted NaCl structure, where the cubic symmetry is preserved. ๐งช #SciArt #ChemSky
๐งช Schottky defects occur in ionic crystals. They are pairs of point defects, where a vacancy at a cation site is matched by a vacancy at an anion site, preserving the charge balance.
Here's my two dimensional paper representation of a Schottky defect in sodium chloride. #SciArt #SciComm
Real crystals are never perfect. This is a two dimensional paper representation of a Frenkel defect. It's a pair of point defects, where an atom is displaced, leaving a vacancy and an interstitial.

I was getting bored of making regular convex deltahedron as paper models for chemists. Delighted with this non-convex distraction. A highly symmetry (icosahedral) 120- faced Mรถbius deltahedron. I'm sure mathematics is art.

Should be Garnet City?
Showing 4 similar white card polyhedra. Three in error, one acceptable.
Testing my net for the bicapped square antiprism. Forth time lucky! 1 missed folding an edge. 2 missed folding another edge. 3 forgot to pay attention to the sequence (made a non convex deltahedron). 4 seems okay. Maybe there's an easier net? #SciArt
I'd like to be added to the SciArt feed.
As a former scientist now more interested in art and representation.
