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 😱

#ChemSky #PiSky #CompChemSky #researchintegrity

...yes, maybe AI hallucinations, welcomed by (i) authors, (ii) reviewers & (iii) editors who don't care, if they turn science into junk, as long as it helps to increase their (i) no. of paper, (ii) citations & (iii) profit margins

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

no serious peer review & editing at "Chemical Papers" (Springer Nature)
...zero interest in #researchintegrity

...👉 retracted in "Carbohydrate Polymers" being now the "Top 1 Journal in Organic Chemistry" counted by IF, see www.chemistryworld.com/news/what-ar...

...self-evidently Top 1 by massive support of citation cartels & brokers.
Here we are in #researchintegrity

...a further absurdity of that "IF list" 👇 at www.chemistryworld.com/news/what-ar...

For Clarivate et al, Physical Chemistry is evidently just a sub-field of Materials Science 😮‍
Also this happens if private companies define "Impact"...

👉Journal Impact Nonsense:
Here's the result of years of systematic JIF gaming by Publishers, Editors & Authors (...and Paper Mills & Citation Cartels) in #Chemsky, #CompChemSky

Journal Impact Nonsense

for us: to ignore = pre-2020
with now > 1 Mio papers/y in Mater+Phys+Chem, you can find junk (at varying degree) everywhere, not only in 'junk journals'

My daily work = separating quality from junk:
- papers to review, read, cite
- people to hire
- project & thesis review
- conferences to attend

Most fraud = "Just" metric gaming, which "doesn’t get read, cited or used"? ...maybe in your field

Mater. Science is overwhelmed w. highly cited Junk!
GenAI already names 'Top Gamers' as 'Top Scientists'.

If we don't act, self-referencing AI will define junk as state-of-the-art

I think this quote is both unsustainable and unsupported by the analysis in the piece. First and foremost, it portrays fraud as *consuming* science rather than merely growing alongside it. Much of the “fraud” in the paper is just metric gaming whackamole that doesn’t get read, cited or used.
