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/...

Congratulations! It was a pleasure handling this paper as one of the Guest Editors for the CJC Special Issue "Highlighting Excellence in Canadian Undergraduate Chemistry Research"

Opinion: Recruiting U.S. scientists is a fine idea – except we’re barely supporting Canadian scientists as it is Before we look to take advantage of fleeing American talent, let’s nurture the Canadian talent we have here by increasing R&D spending

oh no...so sorry to hear this news. Only had the pleasure to meet John a few times, but also immensely enjoyed his rapid and insightful responses on the CFOUR mailing list. Showed you could be a stellar scientist, top notch educator, and a genuinely good human being. A huge loss.

Elbows up, Canada.

Do you know (or are you) a senior scientist in the USA who might like to move to Canada in the near future? The 2026 call for CERCs (Canada Excellence Research Chairs) was posted last month: 🧪 ⚛️ 🔭 🇨🇦

We have an assistant professor position open in the area of STM at Queen's University Canada! As a bonus, the position is very closely associated with the Carbon To Metal Coating Institute (C2MCI), providing opportunities for many collaborations! Please share widely.

Verdazyl-Based Radicals for High-Field Dynamic Nuclear Polarization NMR High-field dynamic nuclear polarization nuclear magnetic resonance (DNP NMR) spectroscopy transfers polarization from unpaired electrons in polarizing agents to nuclei of interest to boost NMR sensitivity. Verdazyl biradicals are a promising choice as polarizing agents because they have been found to generate narrower electron paramagnetic resonance (EPR) signals compared to nitroxide biradicals; an advantageous characteristic for high-field DNP when operating above 400 MHz/263 GHz. The use of verdazyl radicals as DNP polarizing agents has been very limited to date, yet, recent numerical simulations have predicted that verdazyl-nitroxide hybrid biradicals could be more effective polarizing agents than nitroxide-nitroxide biradicals. Herein, the syntheses of a series of verdazyl mono- and biradicals, as well as verdazyl-nitroxide biradicals are described. These radicals were examined in high-field DNP NMR experiments (600 MHz/395 GHz), by measuring 1H signal enhancements directly and through 13C{1H} cross-polarization experiments. X-band EPR, 1H DNP field profiles, and experiments to determine the nuclear build-up times were performed for verdazyl-nitroxide biradicals VerTEMPol and VerTEKol. These hybrid biradicals provide enhancements of up to 100-fold increased signal intensities (i.e., representing >104-fold time savings), approximately four times higher than that of the nitroxide biradical TEKPol, a commonly used polarizing agent in the field.

Congrats to Jakob (first author JACS as an undergrad!!), Zack (the proud mentor and force behind the project), and all the great collaborations with the Brown and Michaelis Groups!

Two isomers of hexane are shown - 2,2-dimethyl butane and 2,3-dimethyl butane. They are labelled as constitutional isomers. Cartoon showing 2 x arsole molecules. The first looks like elon and is doing a nazi salute. It has a methyl group at the 3-position. The second arsole has a red tie, is gesticulating, is orange with a big combover. Face set with a scowel. It has a methl group at the 2-position. They are labelled as unconstitutional arsomers.

My daughter messaged me after her chem class the other day and asked if i could do a cartoon about Trump and Musk as isomers. Dear followers, inspired by Amelia i present to you, unconstitutional arsomers.

*insert applause here*
