Huiru Wang is the latest ICMT student to defend her PhD. Her dissertation title is,
"Electrochemical Atomic Force Microscopy and Spectroscopic Characterization of Amphiphilic Surfactant Molecules as Corrosion Inhibitors",
and much of her research was conducted in collaboration with Dr. Alain Pailleret of France's Sorbonne University in Paris.
The main focus of her research was Atomic Force Microscopy (AFM) investigation of how a quaternary ammonium corrosion inhibitor model compound would adsorb on mica,
then relate the observed phenomena to a ferritic-pearlitic steel. In baseline experiments she also applied AFM to characterize steel surfaces during corrosion,
extracting corrosion rate data which matched values obtained by electrochemical techniques.
She complemented her AFM-based research by conducting Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and X-ray Photoelectron Spectroscopy (XPS) to
independently identify inhibitor adsorption properties as well as electrochemical reaction mechanisms, comparing them with her AFM findings. She will continue her research with ICMT into 2023.
Her advisor is Center Director Prof. Srdjan Nesic.
