Our last report shows how the pyridinophane scaffold allows a fine-tune handle on the reactivity of manganese to prevent side reactions. this work also details important spectroscopic and electrochemical features of these complexes.

[Physics In History @PhysInHistory]

A cat co-authored a scientific paper in 1975, when his owner, a physicist named Jack H. Hetherington, decided to add him as a second author to avoid changing the plural pronouns in his manuscript. The cat’s name was Chester, and he was given the pen name F.D.C. Willard, which stood for Felix Domesticus, Chester. Willard was also the name of Chester’s father. The paper was about atomic behavior at different temperatures, and it was published in Physical Review Letters, a prestigious physics journal.

Chester’s co-authorship was revealed when Hetherington sent some signed copies of the paper to his friends and colleagues, and included the cat’s paw prints as his signature. The story became widely known and amused many people in the scientific community. Chester even published another paper as the sole author in 1980, in a French popular science magazine. He died in 1982, but he is still remembered as the first and only cat to have authored a published scientific paper.

Just out in @InorgChem, @TCUGreenGroup @dfreire2 show that the addition of pyridine rings in manganese complexes of tetra-aza macrocyclic ligands produce critical changes in their ability to disproportionate hydrogen peroxide. Learn all about it: https://t.co/js81XpcqgM

@dgonzales1990 I think it was more like “hey there’s no jobs, but if you stop publishing papers your career is over… so what do I do?… well we can rehire you to keep working but we’ll help you with some sort of stipend aka “salary””

I guess I’m a walking red flag forgetting to eat lunch all the time, until lunch combines with early dinner and I’m hangry lol

Caution! Perchlorate salts are explosive 😵‍💫 but they make nice crystals and are easier to model than triflate 🤣 🤷‍♂️#chemtwitter #phdlife #Chemistry

[David Marcial Freire @dfreire2]

@souvik_mndl @RigakuOxfordXRD @RutgersChem Always better to grow crystals when the lab is semi empty attending conferences 😃 congrats!

[David Marcial Freire @dfreire2]

Also reconnected with my dear friend and mentor Kristof Pota and @ChemChelsea. Great times 😊

[David Marcial Freire @dfreire2]

I had such a great time at #ACSFall2023 in SFO. Gave a talk for the first time, presented a poster in compchem, got to celebrate the birthday of @EmilyPentzer . Met so many great chemists including @kek_kelsie . And spent a good time with @elyandreyna and @DT9Dan

Computational chemistry has transitioned from an elitist activity done by a few to an important investigative tool. Yet, many chemists are speechless in the face of the developments in technology. It’s time for an update. Chemist v2.0.

Meow! #TOCoftheWeek alert! Oliemuller et al synthesize a manganese complex with three-coordinate N-heterocyclic phosphorus fragment; the electrophilic nature of the phosphenium and the nucleophilic Mn center are examined. Please have a look: https://t.co/jYy2qHD5BQ @CThomas_group
