Snippet from an enquiry about a PhD position. Aren't we all inspired by Errors?
Excerpt from an e-mail in which the applicant claims to have read one of my papers, quote: "...where you discuss: Error, Could not generate summary., and I found your research highly inspiring."

The term "Michael Fischer moment" is applied to public jokes, on any topic, that turn out to be embarrassingly unfunny.

Haven't posted here in a while, and now I'm back with something rather unpleasant: An anonymous "concerned reader" contacted a journal in which a (fairly old) paper of mine was published, alleging several methodological shortcomings and requesting retraction of the paper. I suspect that... (1/3)

Can anybody explain to me why #Wiley is doing such a notoriously poor job in typesetting articles? Nowadays, you don't even get a PDF anymore, and 90% of the "corrections" mean reverting changes that the typesetters have made.

Two more retractions have appeared for problematic papers published by Hitler Louis and associates. Journals are slow to respond, but at least some of them do the right thing eventually. #scientificintegrity www.sciencedirect.com/science/arti... pubs.rsc.org/en/content/a...

What may be the longest period between publication as an "Early View" article and inclusion in a regular issue? Clearly, the answer will be "infinity" if an article is retracted after Early View publication, but before final publication. But what about this one? (Almost) 9 years and counting...

When I am late with a review (which happens more often than it should), I usually send the editors an e-mail and apologise. Sometimes, I receive a formal extension, sometimes there's no reply. This time, I received a generous extension by 3 days, from Friday to Monday. No reply would've been better.

The Wiley journal "ChemistrySelect" has retracted four papers by the embattled researcher Hitler Louis and his associates. Following J. Phys. Chem. B (ACS), Scientific Reports (Nature Portfolio), ACS Omega, and Mol. Syst. Des. Eng (RSC), it is the 5th journal to retract some of HL's output. (1/2)

My new #preprint looks at the role of octahedral aluminium sites in #zeolites on adsorption of the anticancer drug 5-fluorouracil. #DFT shows that 5-FU strongly binds to those sites. The bonds do not break in the presence of water, reducing the amount of 5-FU available for #drugdelivery. #compchem

Not sure whether it counts as a hobby, but I do occasionally add observations on inconsistencies in papers on PubPeer. It mostly feels like screaming into the void, but sometimes it can help to correct the scientific record. Kudos to the other two anonymous commenters! pubpeer.com/publications...

Those who are somehow familiar with #H2storage may be surprised to see such storage capacities being claimed in a reputed ACS journal. I alerted the journal more than half a year ago of several things that did not add up in this paper (and another one from the same group). Nothing happened yet...

Merry Christmas and a happy and peaceful end of the year! I'm no good at baking, I have no cat, and my Christmas drinks are nondescript, but one thing I'm decent at is drawing #crystal structures. For the occasion, I prepared the zeolite mazzite (of course, a #zeolite!) in a seasonal attire! 🎄
