So I seem to recall hearing once that certain monofluorinated PAH compounds (ie 1-anthracene or 1-naphthalene positions) were carcinogenic (more-so than either the parent compounds or the chloro-derivatives). However I can seem to find a literature source for this. Does anyone know about this?

CJ, would this channel need to be actively moderated? My only worry is that some might treat it like the chem5ky feed if there are eyes there.

I am sure there is a way* to create and maintain a list of folks, and have their chemchat tagged posts go into the chemchat feed (rather than all of their posts) *I am not volunteering for this

I'm proposing a new hashtag for typical chemistry related conversations.

Publishing this was a 🐈 herding effort! The perspective summarizing the @royalsociety.org #Melanin meeting held last year in Eastbourne is out on @commschem.nature.com 🎉 www.nature.com/articles/s42...

Our group’s latest work is out today in @nature.com ! Our goal is to enable any chemist to be able to easily access an aryne intermediate! So Chris, Sal, and Felicia teamed up to design what we think is the ideal aryne precursor. Danny and @jnboyn.bsky.social helped us understand the activation!

I would like to move chemistry-related conversations to chemchat, seeing as how chem/sky is basically a promotion place now. I would have liked that to have moderated, but it's bluntly clear that the publishing houses can't change their spots

On #chemsky, this is what we refer to as "Schrödinger's sandwich"

Found this bolt in the grass while around town today. It is extremely lightweight. Aluminum? Interesting notches on the end too

In this episode of Inflection Point, hosts David Anderson and @ginacvitale.bsky.social travel back in time to relive three historical moments that led to blockbuster drugs like Ozempic and Wegovy. Listen now: cen.acs.org/pharmaceutic... #chemsky 🧪

@stephy.bsky.social as I recall, we went with "chemsummer" for a while

AbbVie is accepting applications for internships in analytical chemistry: polymers careers.abbvie.com/en/job/2026-... analytical chemistry: automation and spectroscopy careers.abbvie.com/en/job/2026-... chromatography: careers.abbvie.com/en/job/2026-... #chemsky

Is there a hashtag for STEM internships? Merck is accepting applications for internships in cell biology and assay development, immunogenicity, protein metabolism, biostatistics, vaccine communications, DMPK, and discovery and process chemistry.

Hey #ChemSky - if you feel like answering a social media survey, here's one 👇

Derek, being equivocal: "*The drugs do not work.*" (Lol jk)

I don't want the students to learn LAMMPS inputs (at least not in this course), or running another program then importing the output back into their notebook.

#compchem ASE help: I'm trying to create simple examples of MD of zeolites for my students. I thought it would be easy to use ASE, but not at all: it can't do Coulombic or Buckingham interactions. What would be the easiest way to use a “real” force field in ASE? (I'm thinking BKS)

I'm hiring postdocs @berkeleylab.lbl.gov to drive cutting-edge research involving MLIPs, high-throughput workflows, chemical reaction networks, generative models, and open-source software dev. Full position description + application here: forms.gle/zePBZDmciXez... #Chempostdoc #AI4Science

I know it's a forced perspective thing but man, he has small hands!

Outlook (@microsoft.com) just autocorrected the name of one of my students to "Dumb". Every time I type the student's name it autocorrects to "Dumb". Maybe Outlook could use the name field of the recipient to help its autocorrect not change people's names to incorrect names or offensive words.

If anyone needs to know this, most plastic wrap in the US is made from polyethylene, but plastic wrap in Europe is made from PVC. This really matters if you are trying to make a decorative sugar dome for a cake after you saw them do it on a British baking show. #chemsky

One of my favorite annual things I get to go to is a summer bonfire sing-along of "Every Rose Has Its Thorn." An all-time banger.

i firmly believe the inability to *monetize* gratitude is why i have to see christmas decorations in my neighborhood on November 1st.

Local ACE Hardware is playing "Christmastime is Here" from the Peanuts Christmas. I object!

NO IT'S FUCKING NOT (this is how you know I'm a bit tipsy)
