@MIMClab We did this in grad school, but just broke the epoxy holding the old bulb out of its metal housing and then re-glued the new cheap bulb in place, which made the realignment super easy

If you have a UV-Vis-NIR spectrophotometer and the visible lamp goes out, it's very likely a $4 appliance bulb that you can from any home improvement store. Just pop it out & match the V and A settings (it's marked on most bulbs). Or you can pay the 5000% markup from the vendor.

@ScienceNerdSACR Coming from solid state/quantum dots/nanoparticles, “particulate-level” could mean something very large (100s-1000s of nm) and “sub-microscopic” could be referring to optical or electron microscopes with varying size regimes. So I’d go with atomic or molecular

Impactful words by @CarolynBertozzi today on how diversity in her trainees enabled creativity, not playing by the rules, and ultimately the work that built the field of bioorthogonal chemistry. Diverse science leads to better science!

@Chemjobber I’d vote include — seems like only a minor increase in noise comparatively? Maybe include “cluster <subject area>” in the discipline column? presented like that, there are already many positions that I am not eligible for/interested in

I guess I'm asking faculty jobseekers if they want this sort of thing included? Replies (gulp) welcome.

Not for nothing, but as a co-curator/categorizer by nature, these faculty cluster hires are a headache

@sciberius @e_boros Agreed! Though I had to limit myself to those two… 😅 was tempted to also post a picture of CdSe dots or nanoplatelets and get two for one

@wuuchacha @e_boros This is super cool, Brian! I was so sad to see lonely Caesium, it's one of my favorites.

Students in my inorg chem 1 course each get to contribute one element to a periodic table we will construct together. Most have chosen their element, but we have some elements that aren’t getting any love (not selected yet). Drop some fun facts about them to share with my class!

@e_boros Cs+ is a large enough cation that it can stably occupy the A-site in the perovskite crystal structure, which can be used for solar cells, LEDs, etc. Here are some CsPbX3 quantum dots with alloyed halides ranging from X = I (red) to Br (green) to Cl (UV)

@e_boros Mn normally has a forbidden emission transition, but when you add small amounts to a CsPbCl3 quantum dot (normally UV/blue emission, left) you get this amazing orange emission (right)

Having extra fun in the lab today. We stumbled across a pair of laser safety glasses from 1970! Retro PPE is pretty neat. #SafetyFirst

@JMPyper Will that mean lower income tax filers will be harder hit and receive less of a benefit? Not able to take advantage of the full credit when they don’t owe as much in taxes?

Hey #climatetwitter I can bike and ride a free on-demand bus to work, but b/c of poor shuttle MPG, it takes ~4X the gas as when I drive my car and I’m usually the only person on the bus. Better to hope more people will ride the bus with me or drive myself? #altcommute
