Abstract Scope |
Professor Ian Robertson pioneered the use of environmental transmission electron microscopy (ETEM) to understand both how metals oxidize, and how these effects can alter mechanical performance. In this presentation, I will review studies conducted with the aberration-corrected ETEM at the Center for Functional Nanomaterials (CFN), Brookhaven National Laboratory. Aberration correction allows routine, readily interpretable atomic-scale imaging of the initial stages of oxidation. The instrument at the CFN was exploited by a number of research groups to explore these effects in Cu, Al, AuCu alloys as well as in nanoparticles systems used in heterogeneous catalysis. These studies have explored such important aspects as the fundamentals of oxide nucleation, oxidation kinetics, and the role of surface crystallography and defect formation play in these processes. |
