NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 12th Quarterly Report
This NASF-AESF Foundation research project report covers the 12th quarter of project work (October – December 2023) at the University of Georgia. In our previous report, we described our work on performance and effect of surface fluorinated Ti4O7 anodes on PFAS degradation in reactive electrochemical membrane (REM) mode. This quarter, our experiments involved utilizing porous Ti4O7 plates serving both as anodes and membranes. Tests compared pristine and F-18.6 Ti4O7 anodes at current densities of 10 mA/cm2 and 40 mA/cm2. This 12th quarterly report discusses the mechanisms of the effects on EO performance by anode surface fluorination.

Practical Observations in Surface Chemistry and Boundary Layer Control to Enable Scalable Electrochemical Operation - The 57th William Blum Lecture
This paper is based on the 57th William Blum Memorial Lecture at SUR/FIN 2023, in Cleveland, Ohio on June 8, 2023, by Dr. Tim Hall, recipient of the 2023 NASF Scientific Achievement Award. It focuses on the practical effects of controlling the boundary and surface chemistry on a wide range of electrochemical applications. After a brief introduction to the concept and principles of surface and boundary layer properties during electrochemical processes, the use of this approach in controlling various physical properties during electroplating and electrochemical finishing is discussed, including controlling coating stress and metal composition, as well as enabling simple water-based electrolytes to polish passive or complex materials.

NASF/AESF Foundation Research Project #123: Electrochemical Manufacturing for Energy Applications - 7th Quarterly Report
The NASF-AESF Foundation Research Board selected a project on electrodeposition toward developing low-cost and scalable manufacturing processes for hydrogen fuel cells and electrolysis cells for clean transportation and distributed power applications. In this period, we followed our work on 3D printing anode support for solid oxide fuel cells, SOFC (or cathode for solid oxide electrolyzers, SOEC) based on our designed optimization outlined in the previous report. We worked on optimizing the printing parameters, obtaining binder burn out and sintering profiles to obtain printed parts with desired geometry and properties.
