Ontario Centre for the Characterisation of Advanced Materials (OCCAM)

University of Toronto, Toronto, Ontario
What the facility does

Advanced materials characterisation. Support for materials research through leading-edge surface and electron microscopy instrumentation, and full-time scientific staff

Areas of expertise

OCCAM is Canada’s foremost national resource for comprehensive leading-edge materials analysis. Unique to Canada and rare internationally, this $20M facility is an interdisciplinary research centre built around state-of-the-art electron microscopy and surface characterisation tools (see below). Operating in a collaborative research mode, OCCAM provides not only access to leading-edge SEM, ETEM, FIB, XPS, SIMS, SAM, AFM, and LEIS infrastructure, but also dedicated full-time scientific research staff.  Adding to OCCAM’s superior capabilities are the facility’s competencies as Canada’s only fully-equipped characterization institute dedicated to analyzing materials in their native and ‘in-use’ environments. Specialized capabilities include: (1) dynamic characterisation, (2) in-situ characterisation, including complementary techniques developed and integrated to allow for multi-metric characterisation, and (3) highly advanced instrument integration and sample handling/preparation. OCCAM is a nexus of advanced materials research across an incredible array of disciplines and provides a fertile environment for collaborative research.
