So uh Ring just up and said they've got a huge centralized private surveillance network they can leverage all at once huh

Please buy books that are coming out this year.

Doesn’t have to be mine. But there is a stellar release calendar this year especially of Black writers and it would be a shame if one of the fascist victories was people not buying those books (from the indies that are in the fight with us). #BookSky

Awesome!!!! That's great to hear. Thank you so much!!!

Woah! 8 hrs is crazy! What works works though!!

Thank you!!! This is great.

@chemrxiv.org Is there an RSS feed for the new host? I can't seem to find one via Feedly or the new site.

(sorry for the double post, wasn't sure which platform was checked more often)

Love when the science looks like a glitch in the matrix!

Similarly, I love showing my students how to liquid load with it and showing them how you can check your packing/band thickness by watching the little translucent band spread as you push it through your Hx/EA column.

We used it once for a chromatography of spinach pigments demo for the orgo labs when I was an undergrad! Definitely leaves an impact seeing basically "floating" red, orange, green, and blue bands!

I have a single 4L of CHCl3, basically only really use it for liquid loading annoying compounds for columns or chasing off last bits of other solvents before a final high vac excursion.

At least with the EtOH stabilized stuff you can wash with water and then dry/distill. The amylenes on the other hand linger like the glitter after a birthday party for a 6 year old.

I def see much more CCl4 in modern stuff from 🇷🇺 than I do EU, US, CAN, JPN, or even CN!

Read one paper from I think last year that was azeotropically drying with it. Completely alien to me since it's been so regulated my entire life lol.

@barneygrubbs.bsky.social raised that it is probably a recycling GPC! So probably doesn't use that much all said!

Today I Learned!

Plus, when we talk about black-body radiation, we get to talk about the ultraviolet catastrophe, which I'm adamant should be a band name if it isn't already. Share your frustration, Chanda!! Ugh

Black-body radiation - Wikipedia

Black-body radiation is something we’ve understood for over a century, I teach it in my undergrad astrophysics classes, and it’s how the quantum revolution kicked off en.wikipedia.org/wiki/Black-b...

Prep HPLC I've done once! Prep GPC sounds wild. I always am a bit agog when I read like JACS from the 50s-60s where they do prep GC (often annotated as VPC/GLC). Never seen one in action but I picture like a little nozzle just spritzing into a collection bottle lol.

I have seen it one other time....also for like a C-H borylation/silylation system. I do wonder if it's specifically because the pdts are so friggin non-polar and have big volume due to the Bpin/etc.... regardless it def has me scratching my head

"Gel-permeation chromatography (GPC) was performed on SHIMADZU LC-20A equipped with FP-2002 columns."

Guessing they must have it rigged up to a fraction collector or something which threw me

Right! That's my usual inkling when I think GPC, but so far as I can tell after some more digging, the paper I'm looking at is using a polystyrene/DVB column on a Shimadzu and def purifying small molecules. ex. "compound xx was purified via GPC using CHCl3 as solvent"

Hmmm. I guess they must just hook up a GPC column to a standard pump/detector rig and fraction collector.... Always cool/unsettling when you come across a new preparative purification technique you feel like you should have had a handle on

Like....it's gotta be on an instrument right? Not a manual technique

Potentially ignorant question: When a small molecule synthesis paper mentions using "GPC" for purification....what does that mean operationally? GPC immediately is like neon sign for POLYMERS and ANALYTICAL in my head. #chemsky

Don't eat any unnecessarily heartburn inducing foods!

(Or do so in moderation haha)

people keep voluntarily impaling themselves on the "you should all stop being mean to AI because it is BIG and STRONG and my FRIEND" stake, and I'm politely asking them to stop because it's embarrassing
