Yeti Chicago 7/11
7 hour race on the local trails out at Palos -- second place by a hair! Together we set the course record at 10 laps of the 4.5 mile course, just squeezed the last lap in with less than 5 minutes to spare. Second place by something like a minute at the end.
Water structure and dynamics drive ion motion in anion exchange polymers
New paper out in Nature Communications! We used a combination of methods including thin film conductivity, MD and 2D IR to study a dynamics in a new class of anion exchange polymer, connecting structural and dynamical properties from the ultrafast and microscopic all...
Hennepin 100
First hundred miler in the bank! Smashed it at Hennepin. 8th overall, 3rd in age group, just under 18 hours. It was super hot all afternoon, so it was a matter of troubleshooting all day - managing heat, fluids and nutrition. I succeeded in not burning myself to bits...
CMDS 2024 and June 100K’s
A lot of activity this June with two 100K races and a great CMDS conference in York. Kettle Moraine 100K at the beginning of the month was fantastic, won my age group and 10th overall! I was planning on taking it easier in the first half then pushing harder on the way...
Practical implementation of broadband IR probe sources
A new paper many years in the making! We lay out a detailed practical discussion of how we implement broadband supercontinuum IR sources as a probe in ultrafast IR experiments, including many of the things we have learned working with it over the years. We hope this...
Lanthanide transport in MoS2 channels
Check out our paper on studying the transport of lanthanide ions in functionalized MoS2 channels. In this work, we point to new possibilities for designing membranes for tricky lanthanide separations.
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...
