Congrats to Ethan, Bryan and Neil on leading our most recent publication, out now in @Joule_CP! We develop a method to quantify the interfacial pH at an electrode surface using open circuit potential (OCP) transients.

Ever got stuck in a sidewalk shuffle while walking on the street? That’s kind of what happens in a forward bias BPM when weak electrolytes accumulate and impose an ionic blockade, inhibiting the transport of strong electrolytes! Read about it in our latest Nature Energy paper:

I’m giving a talk today at the 74th ISE Meeting at 15:00 (R02 Salon Tête d'Or). If you’re in Lyon and interested in electrochemical CO2 reduction, please stop by!

Check out my first first-author paper of grad school! In this paper, we use weakly coordinating organic cations as bulk supporting electrolyte for aqueous CO2 reduction in order to parse the origin of cation influence on CO production. ⚡️😼⚡️

The rates and selectivity of electrochemical CO2 reduction are known to be strongly influenced by the identity of alkali metal cations in the medium. However, experimentally, it remains unclear...

This paper on the electronic structure of Fe4S4(R1)3(R2) clusters by @BrightonSkeel is a candidate for paper of the year! It's rare to see such a detailed fundamental study. And impressive that the 20 page + 136 page SI is all done by one person. https://t.co/eMzH27jUQG

https://t.co/5H9cWAd26m Electrostatic coupling in the absence of electronic bonding modeled at the graphite electrode/CoTPP interface! Love this new paper from the Hammes-Schiffer lab, alongside our own @corey_kaminsky.

One of the WILDEST projects I've ever seen come to fruition - check out Jo and Andrew's paper on electrochemical P4 synthesis in molten salt electrolytes! 🔥🔥🔥

Elemental white phosphorus (P4) is a key feedstock for the entire phosphorus-derived chemicals industry, spanning everything from herbicides to food additives. The electrochemical reduction of...

1st paper of the new year! Check out Deiaa’s new paper on measuring ORR selectivity in organic electrolytes using RRDE. H2O2 oxidation kinetics can be poor in these media, making these measurements difficult. Read the paper to find out how we address this! https://t.co/E0bNNT8Wis
pubs.acs.org
Understanding the factors that govern the selectivity of the oxygen reduction reaction (ORR) has motivated the study of ORR in nonaqueous media, in which the proton donor can be controlled and...

Thanks so much for organizing this event! I had a great time presenting my work and received really insightful feedback from everyone who stopped by my poster!
Last week was the 4th annual WIC+/CADI Poster Symposium! Thank you to our excellent team of volunteers for putting together yet another successful symposium, our amazing presenters, and our two poster prize winners, @axelovera1 and @sphwng! Looking forward to next year!

Coupled electrochemical half-reactions caught at it again by the meddling kids of the Surendranath group! Thermal redox catalysis by Metal- and Nitrogen-doped Carbon catalysts can occur as half-reactions transferring electrons through band states. https://t.co/5uHDVpvXob (1/2)

So cool to see this work finally in print! Congrats @corey_kaminsky; it was great to be a part of the (unofficial) porphyrin subgroup with you!
Thrilled to see this project published today in @NatureCatalysis! In this paper from @surendranathlab, @sphwng, Josh, @yogi_chem and I report redox liberation by selective solvation of heterogenized molecular catalysts. 🧵below. https://t.co/AKGdHPFG1F

At the triple phase boundary, just like a GDE
this is objective and definitive and I will not be accepting critiques, thank you
