ChBE Seminar: Tuning Collective Molecular Assembly to Influence Ion Transport and Electron Transfer
Speaker: Matthew Gebbie, Assistant Professor, Dept of Chemical & Biological Engineering, University of Wisconsin
Interfaces are critical to many growing societal challenges, especially in renewable energy and sustainable chemistry. Our initial directions focus on exploring new ways to understand and tune collective molecular interactions to influence ion transport and electron transfer, which are essential to energy, catalysis, and biology.
In this talk, Dr. Gebbie will describe early work towards developing new tools to understand how the collective assembly of ions influences ion transport and electron transfer in ionic liquids and super-concentrated electrolytes. In the first part of the talk, he will introduce the use of surface forces measurements to understand electric double-layer formation at solid-electrolyte interfaces in ionic liquids. He will then discuss how these experiments are guiding his group’s emerging initiatives in electrocatalysis and energy storage. In the second part of the seminar, Dr. Gebbie will overview his team’s efforts on implementing quantitative microscopy and data science tools to establish the presence of non-classical transport scaling relationships in ionic liquids and super-concentrated electrolytes. He will conclude by highlighting experiments intended to connect these observations to nanoscale transport mechanisms in self-assembling electrolytes.
Matthew Gebbie joined the Department of Chemical and Biological Engineering at the University of Wisconsin–Madison in fall 2019, where he is the Michael F. and Virginia H. Conway Assistant Professor. He received his B.S. in Chemical Engineering from North Carolina State University in 2010 and Ph.D. in Materials from the University of California, Santa Barbara in 2016. At UCSB, Dr. Gebbie was a 2011–2015 Science and Engineering Fellow in the NSF Center for Nanotechnology in Society, NSF delegate to the 2015 Lindau Nobel Laureate Meeting, and finalist for the 2017 Victor K. LaMer Award. He was then a 2016–2018 GLAM Postdoctoral Fellow at Stanford University before joining UW–Madison. Dr. Gebbie’s research addresses fundamental roadblocks at the intersection of soft matter, interface science, and electrochemistry to achieve the sustainable interconversion of chemical and electrical energy.
