Happy to organize once more the Course on
"Simulation of Materials" within the European MSc in Theoretical Chemistry & Computational Modelling EM-TCCM @emtccm.bsky.social
at IMDEA Nanoscience @imdeanano.bsky.social.
👉Thanks to Org.Team members Cristina, José & Begoña

👇 more "scientific artwork"🤨 in #chemsky, flagged at
pubpeer.com/publications...

....no wonder that the lead authors of this 'high-quality' work are listed in the so-called "World's Top 2% Scientists", Elsevier's annual Vanity Fair for Citation Gamer

I agree, probably "fascination peak is a "Tortured Phrase", but now look what Google's AI tells us about the use of this term👇 ...citing these junk science products as reference to claim that "fascination peak" is in fact a term in spectroscopy 😱

👉"fascination peak" of the "crucial state" in UV/Vis absorption spectra

Another Nobel Prize candidate 💪:
Breaking the Octet Rule with a calculated C12 Nanoring 👇 which "consists of alternating double and triple bonds" (original authors' wording)

UV-Vis Absorption up to a wavelength of 0 nm = infinite energy!!
👉 Nobel Prize or Retraction due to an 'experiment' hand-drawn by 'scientists' working in theoretical chemistry? Elsevier: please decide!

...one can publish EVERYTHING 👇 now in #ChemSky, nobody cares... authors, reviewers, editors, publishers, readers, what a disaster 😮‍ ...but PLEASE don't cite me in such context!
