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.'

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

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”

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