Postdoctoral Researcher at Carnegie Mellon - Donahue Group. Studying air quality and atmospheric chemistry. Prev: UT Austin, University of Michigan. He/Him

[Dr. Eva Pfannerstill @eva_yp]

I am hiring a PhD student! For anyone interested in mass spec, atmospheric chemistry, forests, chambers and Zeppelins. Please forward to any potential candidates! https://t.co/5Ptmzp9Hpb @AtmChemAeroJobs

Been wandering around CERN🇪🇺🇨🇭, jetlagged out of my mind, for a few hours now. It's got real ramshackle, mad-scientist design energy. Very here for it.

New from @Nirvan_AQ in #ESATMOS

Chamber experiments show how different Cl and OH radical sources shift the products of m-xylene oxidation in the atmosphere.

Read the #OpenAccess article now.

New paper in @EnvSciRSC w/ Mrinali Modi, Leif Jahn, and @HildebrandtRuiz! Using different radical precursors (chlorine/nitryl chloride/hydrogen peroxide) impacts gas and particle phase products of m-xylene oxidation: https://t.co/jTuJopb2rC

Starting my postdoc @CAPS_CMU in the Donahue group! I’ll be working on the CLOUD chamber at CERN in the fall!

Ok we all wanna bring back mammoths with cloning, but there are some weirdos I think we should also consider.

PROCOPTODON: giant pug-faced kangaroo with forward-facing eyes. We think it walked instead of hopping. Early Australians met it & I want to feel what they felt

Hi #AAAR members, would anyone have an unused abstract code? Would really appreciate it!

[Nirvan Bhattacharyya @Nirvan_AQ]

@mebrahem1 Already claimed, sorry!

[Nirvan Bhattacharyya @Nirvan_AQ]

This is a great idea! I can’t attend AAAR this year 😢, and have an unused abstract code! Please reach out if you need one! #AAAR2023

[Nirvan Bhattacharyya @Nirvan_AQ]

@EmmanuelChiedu4 No problem! DM’d you!

[Nirvan Bhattacharyya @Nirvan_AQ]

@Kaki_4 @Poppendieck Thank you! I’d be surprised if N95 style carbon masks would be effective? Very small mass of carbon in the filter, I would think (and rapid breakthrough no matter what)! Backflushing might be helpful.

[Nirvan Bhattacharyya @Nirvan_AQ]

We didn’t test these! But I would hazard similar source/sink behavior would occur! Some particular reactions or rates would depend on material thickness, surface area, and composition of course!

[Steyrshrek @steyrshrek]

@Nirvan_AQ @EnvSciTech What about P 95, 99, 100 or R 95, 99, 100 or real N95, 99, 100’s?

[Nirvan Bhattacharyya @Nirvan_AQ]

@Poppendieck Thanks Dustin!

[Nirvan Bhattacharyya @Nirvan_AQ]

Leif has already written about another class of cleaners from this study (https://t.co/TqIkwnCdF4) and Pearl will be publishing on hydrogen peroxide observations as well! Keep an eye out!

[Nirvan Bhattacharyya @Nirvan_AQ]

The first paper from my PhD was published in @EnvSciTech! We studied the interaction of bleach emissions with surgical and KN95 face masks and found interesting adsorptive and reactive behavior! Basically, replace masks often during chemical handling! https://t.co/5wNcqFuMNe

[Nirvan Bhattacharyya @Nirvan_AQ]

This was a collaborative project with @MisztalPawel's group (@daniel_blomdahl), the Novoselac group (@TangMengjia), and @AbuePearl and Dr. Leif Jahn! Advisement from Profs David Allen and @CorsIAQ as well. Glad everyone can read about how we spent year 1 of the pandemic!

[Nirvan Bhattacharyya @Nirvan_AQ]

@Poppendieck @CorsIAQ @JimRosenthal4 What are your test chemicals, if you can share? We had a photo-oxidation filter company that was obsessed with testing small organic VOC removal (<C4) a couple years back (since they might be better at that than activated carbon).

@SkylarkHolly ~$56K USD at Carnegie Mellon starting this summer.
