The role of chemistry on ion transport in confined environments
I'm very glad to have contributed to this new study on the ionic conduction in functionalized MoS2 membranes, which was spearheaded by the groups of Chong Liu and George Schatz. Using FTIR we could correlate the strength of the interaction between the carboxylate...
Fermi or double-well? New insights into zeolite spectroscopy
Our new paper on the IR spectroscopy of hydrated zeolites is out in JPCB! We revisit an enigmatic doublet in the IR spectrum of HZSM5 at low hydration state and argue that the accepted assignment as a Fermi resonance is difficult to reconcile with the spectral...
Potential dependent 2D IR spectra of a molecular monolayer — the plasmon is not superficial
Check out our new letter published in JPCL, Vibrational Probe at the Electrochemical Interface: Dependence on Plasmon Coupling and Potential on the Lineshape in Two-Dimensional Infrared Spectroscopy. We discuss some effects that are relevant in 2D IR spectroscopy of...
Development of electrodes for 2D IR spectroelectrochemistry
Our new paper is out in JPCC discussing the fabrication and characterization of our new platform for integrating 2D IR spectroscopy with electrochemistry. Congratulations to everyone, particularly Melissa on her first publication, and great thanks to Vepa and Jeff on...
Dead Horse 50M
Dead Horse 50M finish, first 50M attempt. Amazingly beautiful environment just north of Canyonlands. The course was certainly more technical than I was anticipating, but that was maybe down to wishful thinking on my part when I read the course description. Struggled...
Chicago Marathon
Great time this weekend in my second running of Chicago -- always fun to see the city from a new perspective. Finished right on target in 3:14:27, didn't try to do too much and nailed my nutrition plan. The weather cooled off perfectly right on time!
Proton dissociation in zeolite HZSM-5
Congratulations to John and the whole team on the publication of our new paper in JPC! We studied the protonation state of the important zeolite HZSM-5 as a function of hydration and showed how the number of water molecules around the BAS causes the deprotonation and...
TRVS 2023
Just got back from a fantastic TRVS in Amsterdam. It was a great conference, lots of exciting talks and some great conversations at the poster sessions. I gave a talk on development of 2D IR spectroelectrochemistry and a poster on water vibrational dynamics in...
Big Bear Squatch North 50K
Participated this past weekend in the 50K distance of the Big Bear Squatch North organized by the Sassquad in the Harriman and Bear Mountain State Parks in the Hudson River valley. This course was no joke! Coming off a serious foot and ankle injury a few months ago...
F3 Lake Half Marathon
Ran in the 2023 F3 Lake Half Marathon this year - conditions could have been better, but that's part of the fun of running a race in Chicago in January! Finished 43rd overall with a time of 1:26:58.
