During the 1990s, the late Dr. Rolf Weil contributed a monthly column in the AESF journal, Plating & Surface Finishing, in which he described the various methods by which the properties of electrodeposits could be measured and characterized. Topics covered include analytical equipment, measurement methods and specific applications. Dr. Weil's practical approach, in layman's terms, aimed at taking the fear out of using sophisticated equipment. What follows is a collection of several of those columns.

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.
