I am co-chairing a session for @acs.org Fall 2024 on engineering systems and microenvironments for electrochemical CO2 reduction. We think it'll be a great session and encourage anyone interested to submit abstracts! Due date is March 31! #Science #ChemSky #CompChemSky

Oral and poster sessions for Engineering CO2 Reduction environments

For this reason, CO2 absorption into the AEL as carbonates is an existential challenge for FB-BPMs, because divalent carbonate anions thoroughly outcompete OH- for recombination sites at the interface. (7/11)

Second, mismatch between the counter-ion fluxes induces observed limiting current densities in forward bias, because when one ion becomes limiting relative to the other, the species in excess will cross-over through the junction and attenuate the achievable voltage. (5/11)

First, the pKa of the recombination product formed at the AEL|CEL interface and the valency of the recombining ion dictate the open circuit potential of the system, because the OCP is achieved at the point where counter-ion recombination and co-ion crossover are balanced. (4/11)

There are many applications where forward-biased BPMs can be useful, from self-humidifying hydrogen fuel cells, to lower voltage electrolyzers, and even to acid-base recombination batteries. However, these systems have long been limited in the rates that they can achieve. (2/11)

No better way to cap off the year than to get to see my thesis fully in print! 📕 In the fashion of Thanksgiving, I just want to say how grateful I am to everyone who helped make this possible. Thankful everyday to have the opportunity to do this work alongside great colleagues!

Spent some time in the Bobst Library at NYU for the first time this past week! What a great place to analyze some NMR!!

No questions of what I’ve been working on these past few years! #CO2 #membranes Hopefully I can add some new words to this cloud soon in the next chapter of my career! #chemsky #greensky Credits: @scholargoggler.bsky.social

Just set up these new 3D printers in Caltech’s new Resnick Center for Sustainability! Can’t wait to get to work using them to fabricate new sustainable electrochemical reactors. ⚡️

Lots of new people on 🦋 today, so I thought I'd introduce myself! I am an electrochemical engineer + incoming PI at NYU. I combine computational models with 3D-printing and reaction engineering to develop electrochemical systems for environmental remediation and decarbonization. #GreenSky #ChemSky

Traveled to Berkeley yesterday to watch my good friend Alex King defend his thesis!! So proud and excited to see the culmination of his incredible work on modeling the photoelectrocatalysis of water and carbon dioxide!
