Sam LevineAnyone want to see a wonky LN2 dewar?
Dr. FerrousTIL "band spectra" is not only a science term; there exists a "Band Spectra". My life is rich is esoterica.
The second round reviews are back for my current in progress paper.
Reviewer 1: Minor revision
Reviewer 2: Do not publish.
My history of divided peer reviews continues. 😆
Me: "For its age this pump looks remarkably clean"
Drains oil, puts in a small amount of fresh oil, runs for 30-45 min, drains again and there is a lot of particulate.
Me: "Hmm"
Opens pump to find out the reason it was clean on the outside was probably because people weren't changing the oil frequently enough.
Mathias MicheelOk das aktuelle Cover der Nachrichten aus der Chemie war dann doch dermaßen witzig schlecht KI-generiert, dass ich dich mal wieder einen Leserbrief schreiben musste. Je länger man draufguckt, umso schlimmer wird es 😅 DER ROBOTER TRÄGT EINE HOSE #AIslop #KIslop #chemiverse #ki #slop
Relatedly if you have one of these lying around the lab and were scratching your head wondering what it was for (I was until yesterday, we have one old one mixed in with the regular stopcocks) I'd be happy to take it/them off your hands if you want to pop it in a padded envelope and ship it.
Andy Napper"How Bell Labs Won Its First Nobel Prize” by Brian Potter.
A great read about the 1925 Davisson and Germer experiment (the canonical “electrons have wave properties” xpt that our chemistry undergrads learn about in physical chemistry class).
Such a long and winding road from inception to realization of what they had discovered. I was unaware of all the details, and found this very enlightening!

When you hear the sound of breaking glass from around the corner and a hushed "oh no".
Anyone know if there is something you can dip TLC plates in to make them act like F254 plates if they didn't come with the fluorophore incorporated? I inherited a box of nice 20x20 glass backed plates without the fluorophore, but I already had a box and use far more fluorescent plates than non-fluorescent ones.
Somewhat shameful chemical secret:
I had to balance two redox equations today (using the half-reaction method I teach in genchem) to quantitatively neutralize two solutions:
◼︎ one of sodium metabisulfate
☞ using hypochlorite (bleach + sodium carbonate)
◼︎ the other of potassium iodate
☞ w/ sodium thiosulfate (photographer's hypo)
I can't think of the last time I had a practical use to balance using the half-reaction method. Oh, the joys of chemistry! 🥰🧪
