Past Events

In this talk, Prof. Galizia will present and discuss new generation spirocyclic molecularly mixed membranes for organic solvent separation, as well as gas separation, exhibiting almost unprecedented selectivity and long- term stability. Structural features associated to the membrane performance will be identified, and effective solutions to mitigate, if not eliminate, the shortcomings of conventional membrane materials will be highlighted. Scaling up of the newly synthesized membranes will be discussed as well.

This presentation will outline our attempts to develop polymer-based high t+ electrolytes wherein anions are appended to a polymer (polyanions) and neutralized with Li ions.

Dr. Balsara's talk will focus on the determination of cation transference number, the fraction of current carried by the cation in an electrolyte of uniform concentration relative to a reference velocity. March 1st, 2:30 – 3:30pm CST EER 3.646 or by Zoom: 828 685 7838, https://utexas.zoom.us/j/8286857838.

Due to their efficiency, small footprint, and ease of use, membrane-based technologies will play a key role in addressing our rapidly growing needs for clean water and energy. Ion-exchange membranes (IEMs), which are made from charged polymers, are integral in electrochemical technologies utilized in water purification (e.g., electrodialysis, membrane capacitive deionization) and energy generation/storage (e.g., reverse electrodialysis, electrolysis, fuel cells, flow batteries). Professor Kamcev will be attending via Zoom. Please join us in CPE 2.222 or https://utexas.zoom.us/j/8286857838.
