06-05-2025 - Welcome New Members to the Kwabi Lab!
This summer, we're exicited to welcome new five undergradate researchers and a postdoc, Andy Ogrinc to the Kwabi Lab. They'll be contributing to a variety of ongoing projects, and we look forward to see their progress! To learn more about their research, visit our People Page.
06-04-2025 - New Paper Published in ACS Applied Energy Materials on Azobenzenes as Potential Negolytes
Our latest paper, titled "Sulfonated Benzo[c]cinnolines for Alkaline RFBs" investigates azobenzenes as potential negolytes for aqueous organic redox flow batteries (AORFBs). Initial studies of methyl red, a common azobenzene dye, revealed degradation via hydrazo bond cleavage. A more stable, rigid azobenzene derivative benzo[c]cinnoline (BC) was hypothesized to offer greater stability under alkaline conditions. Both experimental results and DFT calculations supported this hypothesis, highlighting the enhanced stability of BCs and their potential as a promising new class of electroyles for RFB applications.

05-28-2025 - Congratulations to Bin Yun on Presenting at the Roberts Innovation Fund Showcase
Bin Yun represented our lab at the Roberts Innovation Fund Showcase, presenting his project on photochemical carbon removal from seawater. Our lab was one of the ten recipients selected for this award, which supports promsing technologies with the potential for broad impact.
05-24-2025 - Electrochemical CO₂ Capture Project Launched in Collaboration with the Winter Lab
Our joint project with the Winter Lab has been selected as a recipient of the 2025 Yale Planetary Solutions (YPS) Acceleration Grant.
Our research focuses on developing a biphasic electrochemical process for carbon capture and conversion using proton-coupled electron transfer (PCET). This approach aims to increase CO₂ conversion efficiency while enabling sustainable production of carbon-neutral chemicals—powered by renewable electricity.
We’re grateful for the support and look forward to advancing scalable climate solutions through this collaboration.
04-23-2025 - New Paper Published in ACS Nano on Spiky Nanostructures to Improve RFBs
We’re excited to share our latest work published in ACS Nano, titled "High Capacity Redox-Flow Batteries with High Density Suspensions of Spiky Nanostructured Particles". In this work, we demonstrate that hedgehog-shaped FeSe₂ nanoparticles enable high volumetric capacities in aqueous redox-flow batteries, while maintaining moderate capacity fade rates.

04-09-2025 - New Paper Published in Journal of the Electrochemical Society on NaSICON membranes for RFBs
We're excited to share the latest results of our collaboration in the DOE center MUSIC: "Stress Corrosion Cracking of NaSICON Membranes in Aqueous Electrolytes for Redox-Flow Batteries", published in the Journal of the Electrochemical Society. The study was led by the Dasgupta group at the University of Michigan, and investigates the fracture toughness of sodium super-ionic conductor (NaSICON) membranes when exposed to aqueous environments relevant to redox-flow batteries. Read the full paper here and more about MUSIC here.
03-17-2025 - Kwabi Lab receives Roberts Innovation Fund Award
We are honored to annouce that the Kwabi Group has been awarded a grant from the Roberts Innovation Fund to support our work on photochemical carbon removal from seawater. This award will help us advance our efforts to develop innovative light-driven carbon removal processes to address ocean acidification.
02-28-2025 - Congratulations to Fiki Owhoso on successfully defending her thesis! 🎉
We are proud to celebrate Dr. Fiki Owhoso’s successful oral defense of her thesis:
“Electrochemical and Photo-Assisted pH-Induced Swing for Nitrogen Recovery.”
We’re so proud of you and excited to see what you accomplish next.
01-20-2025 - The Kwabi Lab has moved to Yale University!
We're excited to announce that the Kwabi Lab is now based at Yale University in the Department of Chemical and Environmental Engineering and affiliated with the Yale Center for Natural Carbon Capture. We look forward to continuing our research and collaborations in our new home in Mason Laboratory. Stay tuned for updates on new projects, publications and opportunities to get involved!
