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'?)
Photochemical Formation of Trifluoroacetic Acid: Mechanistic Insights into a Fluoxetine-Related Aryl-CF3 Compound
Trifluoroacetic acid (TFA) is a ubiquitous environmental contaminant; however, its sources are poorly constrained. One understudied source is from the photochemical reactions of aromatic compounds con...

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'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.
