JRL EChem Lab @ Illinois

So proud of our former grad Mike and excited to see the (surely) amazing postdoctoral work he will do @luolab-utah.bsky.social and @minteerlab.bsky.social !

¡Felicidades, @mariaescesc.bsky.social !

This seems very cool! Thanks for posting!

We write an opinion when we have science so hot so important so exciting to say. We’re thrilled to share our thoughts about robots + electrochem 🚀 to the future! #chemsky #electrochem #energysky www.sciencedirect.com/science/arti...

Synthesis, Voltammetry, and Spectroelectrochemical Characterization of Tunable Ferrocene-Jeffamine Redox-Active (Co)polymers: Controlling Redox and Ionic Interactions Through Composition There is a critical need for predictably modulating the reactivity of redox-active polymers (RAPs) to improve their performance in applications such as catalysis, energy storage, and sensing. However,...

Some of the wildest voltammograms we’ve seen! And how to avoid them (just soak!) See our recent grad Nafisa’s systematic redox copolymers - synthesis, CV, SEIRAS and bulk electrolysis tour de force - in collab with @steveczimmerman.bsky.social #chemsky #electrochem pubs.acs.org/doi/10.1021/...

Potential dependent degradation of spinel LiMn2O4 (LMO) and related structures assessed via manganese- and oxygen-sensitive scanning electrochemical microscopy Manganese dissolution has been a long-standing problem that limits the widespread application of Mn-based Li-ion battery (LIB) cathodes, despite their low cost and high Li storage capacity. The accura...

Forever in love with versatile SECM - DongOk Kim’s first paper measuring the degradation of LiMn2O4 and related phases with a tip intercepting evolved O2 and dissolved Mn - making some correlations on HF-, O-loss induced degradation and supression. #chemsky #electrochem pubs.rsc.org/en/Content/A...

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.

You beat us to the post 🥳 An absolute pleasure to work with Nafisa over these years! Pretty soon we will share her work on redox-active polymers!

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.

Faster, better, self-driving electrochemical measurement: the crowning achievement of our recently minted Dr. Mike Pence, showing synergy of simulation and experiment for molecular electrocatalysis. Enjoy! pubs.acs.org/doi/10.1021/...

Congratulations @yingshirleymeng.bsky.social Absolutely deserved and happy to be led by your experience as part of ESRA!

I remember reading “The same and not the same” by R. Hoffmann, forming an impression on how structure changes chem. reactivity. This new lab pub uses our automated e-chem platform with neat electrode arrays for our own version, exploring Au catalyzed glycerol oxidation pubs.acs.org/doi/10.1021/...

If only she knew how much she’s inspired this PI to keep going through long (writing, thinking, dreaming awake) nights…

Cool! ¡Felicidades!

Congrats!

they were a little scatterbrain…

Rookie us, forgot to properly #chemsky our intro 😅

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

bad luck I will miss it!

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!

aaand… 3) JRL presenting in the EN06.04 Redox Flow Battery Symposium in his invited talk on using small electrodes for stochastic, kinetic, and titration experiments on a variety of electrolyes, materials, and interfaces for RFBs! Looking forward to it all #F24MRS

2) Our own awesome @sethchem.bsky.social in the EN11 symposium giving you the full scoop on our new redox-active spin traps for detecting hydroxyl radicals on modified carbons during the ORR using SECM - we promise not a dull moment!

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

at the surface? sorry I won’t be able to make it bc my presentation is at the same time!

cool picture! it could also be a submarine or such 😉

though it looks cool on them! I also want a medal! 😂

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!

¡Qué Sombrerazo, Dr. Rodríguez! Saludos
