The ACS Div. of Analytical Chem. Education Committee launched a "Meet an Analytical Chemist" initiative this spring to highlight members of our community. Our newest entry showcases @shirajoudan.bsky.social, an Asst. Prof. of Chemistry at @ualberta.bsky.social. Check it out here: shorturl.at/7VFIR

Check out our statement and if you are a PFAS researcher who agrees, you can sign on here: www.ipcp.ch/news/sign-on...

Forever chemicals: Scientists condemn massive lobbying campaign to alter PFAS definition

In this issue of Nature Chemistry, I write about the importance of having an online presence that we control ourselves. Since you're all on Bluesky, you're probably already on top of things! Open access sharing link: www.nature.com/articles/doi...

Ok, xkcd 😂 imgs.xkcd.com/comics/mass_...

@shirajoudan.bsky.social of @ualberta.bsky.social is interested in how contaminants get where they are and how we can understand chemical reactions to better understand their fate. Read more: cen.acs.org/environment/... #CENT12 #chemsky 🧪

They’re here! Introducing the Talented 12 Class for 2025. These early-career scientists are taking on big global #chemistry challenges. Meet the 2025 Class: cen.acs.org/people/profi... #CENT12 #chemsky🧪

I'm excited and honoured to be recognized as a C&EN Talented 12! cen.acs.org/environment/... Check out the other fantastic recipients here: cen.acs.org/people/profi... #chemsky

New paper in Environmental Science: Processes & Impacts studying the spontaneous defluorination of some trifluoromethylphenols, led by co-first authors Zhefei Guo (PhD candidate) and Genevieve Tremblay (undergrad!) in my group: doi.org/10.1039/D4EM... (open access 😎)

I have an open postdoc position in my environmental chemistry group at UW-Madison (starting summer or fall). Project focuses on applying high-resolution mass spectrometry to complex mixtures, including PFAS and dissolved organic matter. Email me directly if interested. Application deadline: May 15

Excited to be running another Schlenk line webinar tomorrow with @vacuubrand.bsky.social! There's still time to register using the link below 👇 www.vacuubrand.com/news/webinar...

the best screen to see (and not just because it means I have a new paper coming soon 👀)

wild being in Edmonton, where the sun still doesn’t set for another 40 minutes, and we already know Carney won. still lots of time to watch the specific races in each riding

Hey #chemsky and #science Bleeps (?)...the Chemscrapes project page has been updated to include a free download of a massive poster size parafilm PSA poster for your lab www.chemscrapes.net/s-projects-s... While you're there, check out other ChemScrapes projects. Shares appreciated :)

Thanks to Tamzin for leading this important conversation -- check it out here: pubs.acs.org/doi/10.1021/...

Lab animals deserve enriching environments, but what if our efforts to help unintentionally cause harm? In our ES&T perspective, we explore how leaching plastics and plastic additives may impact fish health, and your experiments...

so excited about this!!! let's goooo

Big life update: I'm starting as an Assistant Professor of Chemistry at the University of Lethbridge! 🔬📚🧪 Feeling excited to be stepping into this new role and connecting with the commuity at ULeth. Huge thanks to everyone who's helped me get here—couldn’t have done it without you.

I'm reporting on what's happening at NSF for @cenmag.bsky.social! If you're a researcher who had an NSF grant that was previously approved for funding but is now in limbo because of what's happening at the agency, my signal is kvasquez.12. Always open to discussing options for anonymity.

The extraterrestrials on my desk and the story of how chemists helped figure out their origins. My latest in @naturechemistry.bsky.social with thanks to @brbobmackesj.bsky.social and the meteorite collection at @vaticanobservatory.bsky.social rdcu.be/eggUr

have you really gone to a conference if you haven’t done karaoke??

Hello, hi, I’m at the ACS meeting for the entire time and haven’t been good about making plans!

I'm beyond excited to share that I've been selected for this year’s #CASFutureLeaders! 🔬 Looking forward to connecting with fellow scientists and diving into this experience in August! 🤩

We are back with another virtual seminar! Join us for a panel discussion on mental health in chemistry on April 23rd. @myatomicnumber.bsky.social @shirajoudan.bsky.social Registration: us02web.zoom.us/webinar/regi... Abstract & bios: www.cheminst.ca/cic_virtual/...

In addition to increased number and $ amount of awards, up to 15% of doctoral awards & 20% of postdoctoral awards will be awarded to international applicants (to be held at 🇨🇦 institution) 🧪 #PhD #research #NSERC #CIHR #SSHRC

A Thesis on the process of publishing a research paper, from writing the intial draft to receiving the acceptance email from the journal, by Shira Joudan @shirajoudan.bsky.social www.nature.com/articles/s41... #chemsky

Major solidarity to those at the Stand Up for Science rallies today. Supporting from across the border 🙌🏽🖤

In the current issue of Nature Chemistry, I wrote about writing peer reviewed papers, through the lens of my research group's first paper. Open access link here: rdcu.be/ectFW @naturechemistry.bsky.social

#chemsky friends, Tony could use a hand He's a multitalented chemist and project manager - hire him! #chemjobs 🧪⚗️

Delighted to contribute some thoughts to this wonderful article in @chemistryworld.com by Rachel Brazil on putting fluorine in drug molecules along with @tnoel82.bsky.social , Veronique Gouverneur, David O'Hagan, and Rob Young! Check it out! #realtimechem www.chemistryworld.com/features/put...

Are mass spectrometers directly included in the tariffs? Or just the parts during production. Stressed about all of the tariffs and the implications of them, but can’t find info on this one

Hello Bluesky community! #ESWN is a non-profit providing opportunities for peer mentoring, community building, and career development for scientists, educators, and professionals who contribute to and support the earth, space, and environmental sciences. Give us a follow and say hi!

Hind was such an energetic researcher and leader, it's hard to imagine she is gone. This is a nice summary of some of her contributions to EDI, in her own words pmc.ncbi.nlm.nih.gov/articles/PMC...

Beautiful mechanistic study of TFA formation from aryl-CF3 groups from @shirajoudan.bsky.social's group (and their first paper 🎉). This helps us better understand the poorly-constrained environmental source of TFA from degradation of pharmaceuticals and pesticides.

Excited to share the first paper from the Joudan lab! “Photochemical formation of trifluoroacetic acid: Mechanistic insights into a fluoxetine-related aryl-CF3 compound” in Environmental Science & Technology: doi.org/10.1021/acs.... I'll describe it below (what do we call BlueSky 'tweetorials'?)

woo!

Hey Canadian scientists, who want to talk to me for a story in Science about Trudeau's legacy in science funding and climate action, and your hopes/fears for the future?

Awesome, Springer Nature now in the AI crap game chemsky🧪

My university is getting rid of the phrase EDI to appease the province?? Is this the dystopian reality I think I am reading? edmontonjournal.com/opinion/colu...

happy 'my class starts monday so I need to make the syllabus' day to those celebrating

happy 2025 and happy 8th night of hannukah! I hope this year brings light, joy and peace, which we desperately need 🤍🤍

As I’m finishing up my second year on this job I realized I didn’t even notice the 2 year mark of living in Edmonton. Time is crazy! So much has happened, yet it’s hard to believe it’s been 2 years since I moved to a city where I knew no one

listening to the new Father John Misty album and cleaning my house, happy solstice ❄️🌝🌚

On Bluesky and Twitter: scientists posting about Science of the Total Environment and Chemosphere losing their impact factors because of fraudulent publishing patterns. On LinkedIn: scientists excitedly sharing their new papers in STOTEN and Chemosphere 🙃

This (via Andrew Gelman via Kevin Drum) is embarrassing and frustrating. It’s good to catch math errors ahead of time. But there’s a larger point here, which is that the chemical industry is opaque about what’s in consumer products, and it shouldn’t be. chemsky 🧪 nationalpost.com/news/canada/...

my brain is in the mode to clean the house and be cozy, but my calendar and to-do list says otherwise!
