I'm not inherently opposed to AI images, but I spent some time trying to get it to make me an illustration of an "industrial electrochemical process" and it came up with this.

The National Weather Service bulletin for Hurricane Katrina, issued 28 August 2005, was the most upsetting document I had ever read in my life at that point, and 20 years later it still is. en.wikipedia.org/wiki/Nationa...

New paper from us today in Joule. Led by Eric Zimmerer, we used operando EXAFS and Raman spectroscopy to structurally characterize disordered intermediate materials during MnO2 cathode cycling. These cathodes are special because they cycle 2 electrons from Mn(IV) to Mn(II).

This week we bid farewell to Calli and Vincent, both high school researchers who joined us through Northeastern's Young Scholars Program (YSP). They studied alkaline CuO cathodes, working with their mentor Yogesh. Great work!

Facebook showed me a snow speeder toy, and I have to share it, not for the snow speeder, but for the early 80s vintage batteries.

Check out this comic! One of my crowning achievements of 2023 was when Luke was presenting the comic at a faculty meeting, they described this panel as "a taller Josh Gallaway."

Andrew and Jamie studied SEI formation in Li-ion batteries using different electrolytes. Summer will seem empty without all of you!

I *wanted* this paper to be about adapting Marcus-type kinetics to MnO2 electrochemistry. But no matter what we tried, adapting a Butler-Volmer expression fit the data better. (AMH=asymmetric Marcus–Hush kinetics)

Alkaline-resistant, compressible, operando cell with a port for a big ole reference electrode. First time using it at a beamline. (Here being aligned with crosshairs and a piece of phosphor.)

Group members Eric Zimmerer and Ben Leifer at #F24MRS. This year all our talks were about Zn batteries 🔋. It was great to see several familiar faces this week.
