UNENE-member professors honoured for best corrosion research paper
Jared Smith, Roger Newman and Suraj Persaud and Jared Smith, who lead the UNENE-NSERC Corrosion Joint Chair Alliance Program, recognized by National Association of Corrosion Engineers (NACE) International.
APRIL 28, 2021 – An article published in CORROSION: The Journal of Science and Engineering and jointly written by three University Network of Excellence in Nuclear Engineering (UNENE) member researchers, has won the 2021 Best Corrosion Paper Award.
Roger Newman of the University of Toronto (U of T), Suraj Persaud of Queen’s University and Jared Smith of Canadian Nuclear Laboratories (CNL) were recognized by the CORROSION editorial board with the award given to the most outstanding manuscript published in the journal in the calendar year preceding the award nomination. The journal is published by National Association of Corrosion Engineers (NACE) International.
The three researchers lead the UNENE-Natural Sciences and Engineering Research Council (NSERC) Corrosion Joint Chair Alliance Program. Newman and Persaud co-run the program while Smith serves as the program’s Technical Advisory Committee (TAC) Chair. The program’s research focuses on examining the corrosion of materials in Canadian nuclear power plants with particular emphasis on nanoscale mechanisms and the combined effect of stress and corrosion.
The article, “Nanoscale Precursor Sites and their Importance in the Prediction of Stress Corrosion Cracking Failure,” reviews recent studies that have applied state-of-the-art microscopy techniques to characterize stress corrosion cracking (SCC). The ability to identify such sites would be instrumental in predicting SCC failure and developing proactive mitigation strategies.
The paper builds on research of modern capabilities in microscopy and computational science for modeling and performing physical characterization of atomic and nanoscale processes related to SCC, specifically, the quantitative micro-nano (QMN) approach.
As well, Newman recently co-authored “A percolation theory for designing corrosion-resistant alloys,” published in the February issue of Nature. This research was done, in part, through the UNENE-NSERC chair program, funded by Ontario Power Generation (OPG) and other industry partners. It provides insights into the role of de-alloying in the degradation of alloys such as those used in nuclear steam generators.
The UNENE-NSERC chair program TAC held a virtual meeting, April 13, featuring presentations from individual researchers including students and chairs from U of T and Queen’s.
