thanks Nick!

Meet an Analytical Chemist – May 2025 Shira Joudan, Assistant ProfessorDepartment of Chemistry, University of Alberta How did you get started in the field of Analytical Chemistry?  In undergrad, I took introductory analytical chemistry…

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

Forever chemicals: Scientists condemn massive lobbying campaign to alter PFAS definition In a letter published Tuesday in a scientific journal, a group of 20 researchers warn that 'this effort is politically and/or economically, rather than scientifically, motivated.'

I know… and there’s a real balance to be had! Don’t hate me for saying it 😫

Controlling our online professional persona Nature Chemistry - Modern scientists exist within the digital world. Shira Joudan describes how an online presence is beneficial to researchers, and what a baseline presence can look like.

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!

Cartoon with the caption “before the bathroom scale was invented, the only way to weigh people was mass spectrometry”. Pictures are two people, a launchpad with a magnet hanging from the roof and a target. One person tells the other: “Rub this balloon against your head, then go jump past that magnet toward the target on the wall”

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

Thanks Rach 💗🥹

Who's that T12-er? Shira Joudan: "There are many, many chemicals in the environment, and only a small number produce harmful effects."

@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/...

Trifluoromethylphenols are environmental transformation products of many agrochemicals and pharmaceuticals, and some can be precursors to TFA. Ideally, understanding which defluorinate and why, can help inform the design of chemicals that do not form persistent degradation products like TFA.

We investigated why/how this happens through an environmental lens, and found that the rate of hydrolytic defluorination is based on the rate constant of the deprotonated phenolate and the fraction deprotonated (dependent on pH). The meta-substituted trifluoromethylphenol does not react
