I am very excited to share our new preprint - "A Zundel Ion in the Catalytic Proton Transfer Pathway of [FeFe]-Hydrogenase" - for which we revisited an older theory of ours, and came to surprising conclusions... 🧵 doi.org/10.26434/che...

Vincent, Morra, and Rodríguez-Maciá demonstrate that truncating the electron transfer domain of [FeFe]-hydrogenase does *not* diminish their catalytic efficiency (via ACS Catalysis). doi.org/10.1021/acsc...

John Clarke, Michel H. Devoret, and John M. Martinis have won the 2025 #NobelPrize in Physics for experiments that revealed quantum behavior in electrical circuits, showing that even systems made of billions of atoms can obey the strange laws of the quantum world: cen.acs.org/people/nobel... 🧪

OMG, thanks for catching! (It's only good for one pulse experiments???)

note: TWT powered, not TNT powered (which would also be cool 💣 💥) TWT = traveling wave tube #NMRchat #EPR #ESR 🧲

A paper describing the performance of our new TWT powered 263 GHz pulse EPR spectrometer is now available as a preprint www.researchsquare.com/article/rs-7...

CD??? We had a 78 rpm vinyl fill track!

ok, first attempt at a Lotus in Point Richmond seems to be going fine

is the dimer core of the H-cluster of FeFe hydrogenase formed by rSAM chemistry in HydE? pubs.acs.org/doi/full/10....

enjoy!!!

a company (I will not name here) decided to throw away money by setting up a solar array AND Tesla Powerwall at the house, charge us a flat rate for the next 25 years, and it starts for less that we were paying for PG&E power before. Yes solar is just a fantasy power source.
