Or how do you make peace with the main scheme of the paper?
While the "initiator" is KMnO4/oxalic acid, PAN chains magically grow directly from chitosan. It must be magic, because this cannot be accomplished with chemistry.
This passed 🍐review, and has been on display in this journal for 15 years.

Re-posting Dr. Wittmers' thread, with a some supporting info.
Fabian flagged a paper in J. Appl. Polym. Sci for region duplication in PXRD (see pubpeer.com/publications... ), and reported it to Wiley. I have found additional duplications and crazy chemistry.
Wiley's response? All 💯 👍

In case you were wondering: the plane is a Type 4 No. 5 Stanley (1874-1884). Probably the oldest I have ever restored.

And here are some cool pictures!
The periodicity of the "bumps" on the lateral force image corresponds to the crystallographic planes bisecting aromatic rings. And the triple bonds are very visible in Raman, even in films ~20 atoms thick (or thin?).

We synthesized few-layer films of γ-graphyne (the ≡ bond carbon allotrope) at a liquid/liquid interface. It's a much cleaner synthesis than our original batch method - and the stacking of the layers is orderly! Coming soon to a 🍐-reviewed journal. Preprint 🠟🠟🠟

It's pretty clear the model plagiarized this old Soviet anti-alcohol poster. It's kind of appropriately hilarious given who is depicted.

So I just opened my fridge, and discovered a very interesting product: poppi prebiotic soda!
Pre/probiotic mix-up is one of my pet peeves. This one gives some definite Engineer vibes.
The soda actually tastes pretty good.

Found it!
It is hiding in the "Save as Image".
What threw me off was the .pdf option in "Save As".
The resulting .SVG plays better with InkScape than any of my previous attempts. Progress!

Marvin cannot export SVG (or the option is cleverly hidden?).
Also, structures copied as .PDF and saved as .PDF open differently by InkScape. Copying completely obliterates any formatting.

I am sure it is possible to get things done with IS, sort of. So far I am extremely unimpressed.
It does not import well from most chemical drawing software.
The UI is a disaster. The inspectors do not follow selection type, there is no "select same" for fonts, etc. But I can rotate artboards!

Also daffodils and hyacinths (though these are not as bad as lilies).
In daffodils, the offending alkaloid is lycorine.

Here is DeepSeek "thinking". It is very sure of itself. By the way, the results are generally better than ChatGPT or Gemini - but it's still not anywhere close to genuine reasoning.

And all to power the bullshit machines. Even if these constructs could be made intelligent, burning down fossil fuels to power them would be unconscionable. Since these are just LLMs, this is also incredibly stupid.

Jut looked it up. Yes, it is a Gemini LLM with bolted-on bits for web search and AlphaGo-like self-play (also done with LLMs).
Taken in isolation, their block diagram could be used as an example of how *not* to do science. And LLMs fundamentally cannot reason.
I just wish the LLM bubble pops soon.

I want to tap into the collective intelligence of ChemSky and learn a bit about EXAFS.
I just came across the EXAFS spectra and fitting parameters attached here. Do these look broadly reasonable? If not, why?
The source paper will for now remain nameless, but it has fake Raman data.

This is probably the funniest/fakest PXRD pattern I have ever seen (and I go through a lot of papermill products). Found in US patent application US 2023/0088084 A1.
Brought to you by the same fine people who "discovered" "holey graphyne".

Deepseek is better than ChatGPT 4o on my "brick/feathers" test.
It gave a correct answer 4 out of 5 times. ChatGPT answered wrong 4 out of 5 times, and Gemini failed hilariously and spectacularly 100% of the time.

The current incarnation of imitative "AI" is as useful as a calculator that is wrong 35% of the time.
I just asked Gemini and ChatGPT what is heavier, 1 kg of feathers or 2 lb of bricks. Both models said the bricks are heavier 😂
