Our Research
We want to gain a fundamental understanding of radiation-induce degradation of metals. We study materials relevant to the nuclear industry, including copper and stainless steels, using state-of-the-art scanning electrochemical probes. We have unique access to highly ionizing radiation with the SLOWPOKE-2 nuclear reactor.
​
Research projects include:
-
Hydrogen absorption in copper.
-
Decoupling radiolysis and radiation-induced defects during stainless steel corrosion.
-
Simultaneous corrosion and mechanical crack formation (i.e., stress corrosion cracking) in the presence of radiation of stainless steels.
-
Advancing scanning Kelvin probe technique for localized corrosion analysis.
-
Radiolysis and corrosion modelling.

Facilities
Our group has unique access to highly ionizing radiation at the SLOWPOKE-2 Facilities at RMC. Along with highly localized probe techniques with nm to um scale lateral resolution, we have a unique perspective of the most fundamental degradation processes. RMC is equipped with many surface analysis techniques (SEM, EDX, XRD) of which students can become independent users.
