Bionanocorrosion Lab

Western University (The University of Western Ontario), London, Ontario
What the facility does

Research on the corrosion and biointerface of materials, including nanomaterials.

Areas of expertise

The Bionanocorrosion Lab combines classical corrosion science with colloid and surface chemistry. Our applications and projects range from health and safety relevant projects (corrosion and stability of nanomaterials and implant materials in the human body, consumer health, regulatory compliance of materials and products) to classical corrosion performance (atmospheric corrosion, tribocorrosion, corrosion-protective coatings). A strength of the lab is that it can investigate the entire material-solution interface by combining material and surface characterization with solution analysis and many in-situ experimental methods. The lab is equipped for metal speciation (for example, the distinction between trivalent and hexavalent chromium) both in the liquid and solid phase. Our core expertise includes corrosion science, physical, analytical, and electrochemistry, materials science and engineering, and health aspects of materials, including toxicology aspects and metal allergy. We collaborate with a wide range of scientists, engineers, physicians, industry, and not-for-profit partners.
