The cooking organic aerosol (COA) signal in suburbia is pretty strong today. Maybe should have opted for the leaner ground beef…. 🤔🔥 #atmoschem #aerosols #SummerModeON

The researchers found that one of the disposable vapes they studied released more lead during a day’s worth of use than almost 20 packs of tobacco cigarettes. cen.acs.org/business/con... #chemsky 🧪

AQ sensor in my office on campus… and while there are other indoor PM sources from construction, this spike overnight on July 4 is most likely the massive *private citizen* use of fireworks. And this is indoors in a MERV14 building! 🧪⚗️🇺🇸

Thanks to everyone on #TeamMassSpec for a great #ASMS2025 - my first! I’m coming away with great new connections, inspirations, and ideas for our current research in multiphase atmospheric and indoor chemistry. #IndoorChem #AtmosChem 🧪⚗️

THE entire NIOSH engineering group has been fired among most ALL of NIOSH. It is devastating. www.cbsnews.com/news/worker-...

FYI: The Spencer Foundation, Kapor Foundation, The William T. Grant Foundation, and the Alfred P. Sloan Foundation have collaborated to offer $25K rapid response grants. "This rapid response bridge funding opportunity is for scholars and teams whose grants have recently been cancelled by NSF."

While idly perusing the PurpleAir #PM2.5 map today -- it's an amazingly clean day in the Northeast US, but there was this one red sensor in Ohio, north of Cincy. And then I saw that it was ironically located just outside the town of "Mount Healthy". #AirQuality #SpikeyTimeSeries 🧪⚗️

This week we were notified that our Thriving Communities grant to build community capacity and study #AirQuality in the #Anthracite #Coal Region of PA was selected for an award! It was not ideal to see that we were awarded frozen (EPA) funds that we aren’t sure that we will ever really get.

NIH-supported Environmental Health Perspectives is the open-access flagship journal in environmental health. They have paused all new manuscript submissions "due to changes in operational resources". Is this the transparency and open discourse we were promised? ehp.niehs.nih.gov/do/10.5555/b...

Was just reading a #NYTimes Morning email blast with an article reflecting on Spring 2020…. 5 years later. This question hit me harder than I thought it would. Hugs requiring a calculation. Oof. Think about what it’ll be like to explain this idea to kids in 10-15 years.

Hey #ChemSky, any chemists or chem students attending to the Stand Up for Science event in Sacramento? I'll be attending and would like to speak with you either at the event or beforehand!

All probationary federal employees at NOAA’s EMC that’s responsible for keeping all US weather model systems running have been fired with 1 hours notice. And that includes me and colleagues. We will not go quietly because we care about the NOAA mission to protect the public.

If you’re an industry chemist who holds a BS/BA in Chemistry, we want to have a (compensated) conversation with you 🤗 Please share widely with chemical industry friends and colleagues! #ChemSky

Apropos of *absoloutely nothing* science 🧪 friends, this is your friendly reminder to read the grant solicitation VERY thoroughly when you *start* writing so you don’t have to reformat/rewrite/cut down your whole grant in like 6 hours right at the deadline. ⚗️ #academicsky #chemsky

Students interested in #NASA and/or planet Earth 🌍 should really consider applying for SARP.

I’m looking for new PhD students wanting to use computational chemistry to study atmospheric reactions. Topics: Hg redox reactions at surfaces. AI to study how hydrogen bonds (R=O--HO• and RO(H)--HO) affects kinetics of H-abstraction. See www.esf.edu/faculty/dibble or [email protected]

How to deal with abysmal #airquality in SoCal due to the fires 🔥 mask up w/ a good mask (N95 or P100) Avoid outdoor intense activity Turn on air filters if you have them a Corsi-Corsi-Rosenthal box *really* worked during NorCal's fires

In Dover, NH 2008-09: $450 for an attic bedroom in 100 yr old shared Victorian. Good people, good location, non-existent insulation. 🥶 San Diego, CA 2009: half of a 2BR 2BA for $750 near UCSD. Nice but boring area. Prob up 2-3x now (?) 💸 similar rent for shared 2BR in Pacific Beach the next year

Let’s be honest there is a big circle around this whole Venn diagram labeled “Analytical” except those who reside in only the outer circle don’t clog the #MassSpec ion source routinely.

Anyone dealt with AI-generated reviews on papers? I just had a paper rejected by ACS with 2 positive reviews noting novel work / minor corrections, but 1 scathing review with broad statements with no evidence and clearly didn't read the SI). AI checkers put this review at 100% AI generated...

So much to consider here. I also get this complaint - even suggested I would “probably fail the course if I was a student”. Students really struggle with tolerating small failures, and want a LOT fed directly to them. Struggle to see thru math to chemistry. A challenge for us all to address

Ephraim was a excellent chemist, educator, advocate, mentor, and very kind person. He made P-Chem approachable without diluting the challenge. I base most of my teaching philosophy for problem solving on his example. I miss him. #chemsky #PUI #mentor www.threads.net/@colgateuniv...
