STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

We deliver microscopy imaging services and training on advanced microscopes with demonstrated resolution on the order of fractions of a nanometer. As a shared multi-user facility, CeNSR provides open ...

Led by Arthur Blackburn, co-director of UVic's Advanced Microscopy Facility, the team developed a novel imaging technique that allowed them to achieve sub-Ångström resolution using a compact, ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

Although both a SEM and a TEM are electron microscopes, their working principles and images are very different. Whereas an SEM uses secondary electrons ejected after bombarding a sample’s surface with ...

The FEI Philips XL 40 Environmental Scanning Microscope (ESEM) is a large-chamber, tungsten source, environmental scanning electron microscope capable of high and low vacuum imaging. The FEI Philips ...
