In our ChemSci Pick of the Week, Tomislav Friščić et al have reported direct mechanocatalysis by resonant acoustic mixing.

The method uses a metal surface to directly catalyse copper-catalysed alkyne-azide click coupling reactions under the conditions of resonant acoustic mixing.

In our ChemSci Pick of the Week, Xavier Companyó et al. (University of Barcelona, Spain) report a new catalytic methodology to construct α-allyl ketones via defluorinative allylation of silyl enol ethers in a regio- diastereo- and enantioselective manner. The protocol uses the unique features of the fluorine atom to simultaneously act as a leaving group and to activate the fluorophilic nucleophile via a Si–F interaction.

In this , Wybren Jan Buma (University of Amsterdam, the Netherlands), Wiktor Szymanski and Ben L. Feringa et al (University of Groningen, the Netherlands) present a simple strategy to boost the reactivity of the 9,10-phenanthrenequinone (PQ) triplet state to further enhance the efficiency of the light-induced photocycloaddition of 9,10-phenanthrenequinone with electron-rich alkenes reaction (PQ-ERA).

I have a background in and learned Fortran on punch cards. I got a 128K Macintosh and wrote for Macintosh and Windows. It's still sold today, but I haven't been associated with it since 2007.
Since then, I have played a lot of , but face-to-face bridge is a Covid disaster.
I don't say much, mostly I like to follow a few specific journalists, infosec, legal, econ, medical voices, and local news.

FDA Removes Harmful Chemicals From Food Packaging

The FDA "announced the removal of the endocrine-disrupting chemicals (EDCs) per- and polyfluoroalkyl substances () from food packaging.

Issued on February 28, 2024, "this means the major source of dietary exposure to PFAS from food packaging like fast-food wrappers, microwave popcorn bags, take-out paperboard containers, and pet food bags is being eliminated," the FDA said in a statement."

Saw someone talking about skills trees for real life, and remembered that way back in 2019, I actually started making one for chemistry. Might be worth returning to as a great distraction.

We totally randomly met two riders this morning near our home, apparently they're traveling around & with bicycles. They are a & couple. We invited them at my mom's home and we all had lunch together. Apparently they are candidates in , one in and the other one in . Very interesting young people. It was a good day today.

Do you want to actively support the fight for #climate and environmental justice in Canada?

#Research for the Front Lines is expanding our network and we’re particularly looking for people with backgrounds in applied science or analytical testing of environmental pollutants who can volunteer some labour to enhance the support we provide to #Indigenous Land Defenders and other frontline folks.

Looks like another helium shortage, supply disruption. It's a non renewable on Earth - hopefully frivolous use like in party balloons etc will stop.

Helium is an essential material for research and medical equipment, but it's nonrenewable and difficult to recycle

in 1911 the French Academy of Sciences rejected the membership application of Marie Curie.

In 1910 Curie succeeded in isolating radium; she also defined an international standard for radioactive emissions that was eventually named for her and Pierre (the Ci). Nevertheless, in 1911 the French Academy of Sciences failed, by 1 or 2 votes, to elect her to membership in the academy. Elected instead was Édouard Branly. via @Wikipedia

HA!!!

Just learned today that the substance used in diapers -- sodium polyacrylate -- is the same stuff in reusable freezer ice packs

So yes, a frozen diaper could be useful as a heatwave cooling item.

Belgian chemist, industrialist and philanthropist Ernest Solvay was born #OTD in 1838.

He is best known for his pioneering work in the chemical industry and for the establishment of the Solvay process for the manufacture of soda ash (sodium carbonate). In 1911, he began a series of important conferences in physics, known as the Solvay Conferences, whose participants included Max Planck, Ernest Rutherford, Maria Skłodowska-Curie, Henri Poincaré, and Albert Einstein.
