🎇🧨🎆Waterworks for the New Year!🎆🧨 I dropped fluorescein in water and rhodamine B in isopropanol into water to visualize miscibility and diffusion. #FluorescenceFriday #SciArt #SciComm #RealTimeChem #Chemistry #ChemTwitter

🧪 New optics blog post! What is an optical caustic? skullsinthestars.com/2026/01/16/w...

Laser weeding is one of those “no wa-well actually no that makes perfect sense doesn’t it” things.

Why are cage rail optical assemblies so satisfying? #adultsciencelegos #chemsky

Hey everyone, We literally just added 100 more trans girl scouts to the trans girl scout cookie list. The list is bigger than it has ever been in EITM history. Go get some cookies and make a trans scout's day!

The world may be falling apart, but at least Thorlabs has their priorities correct #chemsky

No cheating, repost with the most recent photo of your pet.

AIST has SDBS - I haven’t used it in quite a while but it’s free!

I’m finding I really don’t like Bluesky (sorry y’all!) - even the chronological order OnlyPosts and Following feeds are trying to incite rage. I suspect it’s because there are still enough people using the algo feeds that folks are still (maybe unknowingly!) incentivized to chase rage likes.

Re: everybody getting got by an ai dog video: I want to talk about propaganda in general as well as ai in specific. We are awash in way too much stuff to pay deep attention to and that's absolutely by design.

Hey, this is a long shot but maybe someone on here can help. My sister and her wife were accepted to university in Rennes and need to move there before the January term starts, but they’re having trouble finding housing. Can anyone rent them a room? Even short term is helpful.

I got life-changingly sick right around when I defended. I could not have relocated, and also there were no jobs in organic semiconductors. I went to a random symposium on campus because I’m a seminar junkie, met someone at an industry poster session, and now I do photonics.

In the aurora, both reds and greens come from fluorescence from oxygen, mostly the from the 1S excited state (green) and from the 1D excited state (red) The 1D state has a lifetime of >150 seconds, whereas the 1S state has a lifetime of ~1 second

The fact that hotels would not have a real bathroom door scares me. bringbackdoors.com

🧪 #chemsky A new single crystal was recently synthesized and obtained, featuring two individual crystals that grew together. This is the second time I have observed this kind of intergrown or concomitant single crystal pair. #Chemistry #SingleCrystal

Know the difference.

Doesn’t happen often, but on rare occasions, someone does something so damn cool with organic semiconductors that even I’m impressed

Patriarchy tolerates violence from men while insisting you soften your words and be “nice” and never get visibly angry? 🤝 Barbarian suddenly feeling weak and taking full damage after a long fight? Problematic rage gap

What perfect album came out when you turned 16? Note: This one’s an amazing straight-through album for a breakup. Note also: I skipped a grade, so I feel like I should be able to claim Blackwater Park instead - released right around my 15th birthday. My favorite album for the past 20+ years.

I do think we’re focusing too much on how much a capital gains tax would bring in and not enough on the “fuck landlords and fuck em hard” aspect of it

ok FINE I’ll stop hating on Python now

Anyone else hearing about conferences being canceled because of the shutdown?

Starting to feel like I have to go meet a guy in a back alley to get #semiconductor epi substrates these days. Can we please stop this trade war bullshit? It really hurts when China retaliates. I would like to keep having a job. #Chemsky anyone else feeling indium deficient these days?

Wafers lost in shipment #chemsky #photonics #semiconductor

Back on my insomniac medical journal reading bullshit, for reasons. Surprised at how much sense the papers make now vs. 10 years ago when I was new to this. Anyone on #chemsky working on autoimmune kidney disease?

Okay, but now I'm curious...#chemsky what's on your science-themed playlists?

quick while the government is shut down let’s all switch to metric

Speckle patterns are goddamn sorcery

Color doesn’t exist outside the brain. 🧠 From fruit flies to humans, perception transforms raw light into hues, even nonspectral ones like purple. New work is mapping the neural circuits that make color possible. 🎨 Learn more about color perception in the Sept/Oct issue of #PhotonicsFocus!

Does anyone on Bluesky research proteins that are stable at high temperatures? 👀 #science #biosky #chemsky

Occasionally I have a dream where I’m arguing with someone about organic chemistry and I say something and wake up and…it was perfectly correct and coherent Damn, It’s in my brain pretty deep. And I miss it terribly. I like waferland but I am, technically, a long way from home 😭

I agree with this and I don’t. There are a lot of grey areas, and humans are vicious and will kill each other with hammers. But we have a responsibility to build only the things that can help us build a better world, and that excludes a lot.

‘"We never in our wildest dreams would have expected a 75% slowing of clinical progression,”… None of the patients who have been treated are being identified, but one was medically retired and has returned to work. Others in the trial are still walking despite being expected to need a wheelchair.’

Today we're dissolving gold in aqua regia! Gold is expensive, but in the scheme of things for a synthesis lab the price (~$183/g) is not that different to other speciality chemicals. ##ChemSky #OzChem

Slightly diminish a book: Misdemeanor and Punishment The Two Musketeers The Junior Engineer’s Path Sometimes Coming Home Catch-21 Monosecure Moissanite Age Shack of Leaves (a series!) The Squire of the Rings

Go home, science, you’re drunk

Hey #chemsky and #crystalgrowth folks - anyone here have expertise on metal contamination in III-V #semiconductor wafers? Looking for some benchmarks and the kind of data I suspect doesn’t often see the light of day in publications. It’s a long shot, I know.

"Good day Sir, here are today's options. Would you like anisotropic peak broadening, diffuse streaks, superstructure peaks, or twinning?" "Yes, please" #Crystallography #totalscattering #TheCuteLittleCrystal

pursue your goals. do not give up. you are evolved to be a persistence hunter. exhaust your goals. make your goals physically incapable of escaping you.

I’ve been telling folks CVS is evil for like a decade now, because of the way they treat disabled folks…they’ve driven their own pharmacists to suicide..I’m not surprised at all. PLEASE #boycott them!

in this funding hellscape I’m increasingly seeing startup founders as little Robin Hoods, siphoning off a little money from the VC class where they can, redistributing it so we can sort of afford to survive, helping us stave off the technofeudalism a little longer

"people who are still concerned about covid are so unreasonable, they just want us all to go into lockdown again!" literally nobody is asking for that. what people are asking for is stuff like universal masking in healthcare settings and investment in indoor air filtration/clean air infrastructure

Is this true? I think I remember listing something like “younger chemists are getting nothing out of this, why should I maintain membership” on a survey a number of years ago. I guess someone was listening.

What if we replace “synthesis and characterization” in every paper with FAFO 🤣

I am working to become the chemistry pope It will soon be a sin to invoke spin-orbit coupling, motherfuckers

every time people talk about colonizing space i think about taht one post that goes like "scientists found a heaven like planet where you can drink beers by the lake. they call it earth"
