Scientists in using electron Microscope

Electron Microscopy Facility

at Cornell University

PARADIM’s electron microscopy (EM) facility leverages and expands on existing capabilities in the Cornell Center for Materials Research (CCMR, a research center that includes an NSF-funded Materials Research Science and Engineering Center, MRSEC DMR-1719875) giving users access to a unique set of advanced analysis tools for materials characterization. These electron microscopy facilities are part of the Cornell Center for Materials Research but can be accessed via the PARADIM user program. Reviewed and approved PARADIM user projects receive access to the facilities and to imaging and sample preparation support from PARADIM staff. As with other PARADIM resources, access is without charge to approved US academic and government projects. Preference will be given to projects in which characterization is part of larger materials by design effort.


Electron Microscopy New Capabilities
