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.

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 ...

A unique laboratory at Michigan Tech captured microscopic photography of snowflakes in a demonstration of the lab's high-powered scanning electron microscope. The Applied Chemical and Morphological ...

This picture is composed of 4,225 scanning electron microscope images. It shows a microchip based on 65-nanometre technology. This means that the smallest structure on the chip that can be reliably ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

In the world of nanotechnology, where structures are measured in billionths of a meter, precise imaging and measurement techniques are essential. Critical Dimension Scanning Electron Microscopy ...

Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.

Goethe University Frankfurt (Germany) ceremonially commissioned a state-of-the-art cryo plasma-FIB scanning electron microscope with nanomanipulator worth more than 5 million euros on Thursday. The ...

To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are ...
