A Review of Anodizing Processes in Nano-Engineering in Mechanical Industries: Aluminum Oxide Membrane Alloys for Corrosion Protection
This review covers published research on the anodic oxide protection layers principles and requirements for process engineering application, the effect of the anodizing process parameters, as well as the importance of process steps taking place before and after anodizing.
Aluminum anodizing and its alloys are widely used in the fields of engineering aerospace and machine manufacturing and have drawn much attention from both researchers and engineers as promising materials for electrical appliances and the machine industry. They provide good strength-to-weight ratio at a reasonable cost, but exhibit only limited corrosion resistance. Therefore, a durable and effective corrosion protection system is required to fulfill structural integrity. The present review covers published research on the anodic oxide protection layers principles and requirements for process engineering application, the effect of the anodizing process parameters, as well as the importance of process steps taking place before and after anodizing. The principles of assembly are discussed together with the properties of nanoparticles and layer-by-layer polymeric assembly essential in building hybrid coatings.

NASF/AESF Foundation Research Project #120: Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters – January – December 2023
This NASF-AESF Foundation research project report covers quarterly reporting for the year 2023 at the University of Illinois at Chicago. The objective of this work is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater. Discussed here are the oxidation of PFOA with three different catalysts, development of a method for detecting PFAS, as well as work on 6:2-fluorotelomersulfonic acid (6:2 FTS) and electrodeposited bismuth/tin oxide catalysts.
