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.

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.

Microscopic analysis is a core component of material science, helping researchers understand the minutiae underpinning ...

Environmental Scanning Electron Microscopy (ESEM) represents a significant evolution of conventional scanning electron microscopy. By utilising variable pressure conditions rather than the high vacuum ...

A scanning electron microscope image shows sodium carbonates in a sample from the asteroid Bennu. Each needle is less than one micrometer wide by five to ten micrometers in length—for comparison, a ...
