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 ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Scanning electron microscopy is a general type of electron microscopy that generates a topological image of a sample using a beam of electrons to achieve much higher spatial resolution than light ...

The scanning electron microscope, a large-scale facility at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) DLR Institute of Engineering Thermodynamics in Stuttgart, is ...

Two new papers describe hints to a brine-filled environment on the 4.5-billion-year-old space rock and the presence of amino ...

Scanning electron microscopy (SEM) is an advanced analytical tool that massively outstrips the capabilities of traditional light microscopy. Using visible wavelengths of light on the 400 – 700 ...

STEM is capable of producing images with spatial resolution down to the atomic level, thanks to the fine electron probe it utilizes. Scanning Transmission Electron Microscopy (STEM) and Transmission ...

The Electron and Scanning Probe Microscopy Unit provides solutions for imaging and analysis at the nanoscale. The unit houses two scanning electron microscopes, two scanning probe microscopes and ...

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.

A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts and minerals ...
