Interfacial electron transfer for (redox flow) batteries has so many mysteries to be uncovered and understood. Here’s a lamp (or an LED or a candle, your choice) to try illuminating some answers. It took a few years to see the light, but great collab within JCESR Hub. pubs.rsc.org/en/content/a...

Closed-Loop Navigation of a Kinetic Zone Diagram for Redox-Mediated Electrocatalysis Using Bayesian Optimization, a Digital Twin, and Automated Electrochemistry
Molecular electrocatalysis campaigns often require tuning multiple experimental parameters to obtain kinetically insightful electrochemical measurements, a prohibitively time-consuming task when performing comprehensive studies across multiple catalysts and substrates. In this work, we present an autonomous workflow that combines Bayesian optimization and automated electrochemistry to perform fully unsupervised cyclic voltammetry (CV) studies of molecular electrocatalysis. We developed CV descriptors that leveraged the conceptual framework of the EC′ (where EC′ denotes an electrochemical step followed by a catalytic chemical step) kinetic zone diagram to enable efficient Bayesian optimization. The CV descriptor’s effect on optimization performance was evaluated using a digital twin of our autonomous experimental platform, quantifying the accuracy of obtained kinetic values against the known ground truth. We demonstrated our platform experimentally by performing autonomous studies of TEMPO-catalyzed ethanol and isopropanol electro-oxidation, demonstrating rapid identification of kinetically insightful conditions in 10 or less iterations through the closed-loop workflow. Overall, this work highlights the application of autonomous electrochemical platforms to accelerate mechanistic studies in molecular electrocatalysis and beyond.

Bluesky, Today is my 2nd day on here as an escapee from The Bad Place. I am BEGGING y’all to repost this I have $80,000 in scholarship money to give away to women and girls NATIONWIDE. I worked so hard to raise this money. Applications open THIS week. I’m scared the mass migration will impact this
Had an amazing time at #F24MRS discussing science, presenting our work, organizing and chairing a symposium, and engaging with colleagues and NEW collaborators - what a great environment in these meetings. Not a materials scientist by training, but ever learning and feeling appreciated by MRS/JMR!
Hope to see you in Boston for #F24MRS featuring: 1) Symposium EN11: Nitrogen-doped Carbon—From Fundamental Understanding to Applications in Electrochemical Devices organized by JRL, Cullen, Meunier and Romo - Join us for 1.5 days of carbon fun at the Hynes center L3-305 starting Wed 12/04 morning
Grad LORs are in! This year our group sends out an outstanding cohort of undergraduates ready for graduate prime time. And to spread the echem message. “Have you ever heard of ultramicroelectrodes and what they can do for you?” Congrats to Martha, Hayden, Curtis, and Michelle for their next step!
