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.

Read MoreLooking Back: The Columnists
Many industrial/technical journals consist of a well-rounded mixture of technical papers, practical articles about technology and how-to-do-it features, including this one, Products Finishing. In its decades of publication, the AESF/NASF journal, Plating & Surface Finishing also endeavored to meet this need. Among the many features were those of the columnists, recognized experts who had expertise in certain segments of the surface finishing industry. This article contains a sampling of columns published in P&SF over the years, which still retain information of importance even today.
