The family of electron microscopy techniques have become staple methods for imaging nanoscale objects, including nanoparticles, viruses and proteins. The appeal of electron microscopy as a ...

Coatings are required to remove or diminish the electrical charges that promptly accumulate in a nonconducting material when examined by a high-energy electron beam. Material samples investigated at ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

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 ...

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.
