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 #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 11th Quarterly Report
In our last report, we described the performance and effect of surface fluorinated Ti4O7 anodes on PFAS degradation in a batch reactor operation mode. In this report, we will discuss the effect of surface fluorinated Ti4O7 anodes on PFAS degradation in a reactive electrochemical membrane (REM) operation mode.

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.

NASF/AESF Foundation Research Project #122: Electrochemical Manufacturing for Energy Applications
This NASF-AESF Foundation research project report covers the ninth quarter of project work (January-March 2024) at the University of Texas at Dallas. 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). We focused on the mechanical properties of 3D printed yttria-stabilized zirconia (YSZ) using a four-point bending test. We then conducted a statistical analysis to characterize the flexural strength of porous 3D printed YSZ.

Looking 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.
