High-resolution scanning electron microscope (SEM) images of fossil cell coverings of nannoplankton (coccolithophores) highlighting holes that would have allowed flagella and haptonema to emerge from ...

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 ...

This instrument is an ultra-high-resolution scanning electron microscope capable of secondary-electron image resolution of 1.2 nm. It is fully digital and incorporates an image archiving computer.

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

Over 50 years ago, the first commercially available SEM was unveiled. Yet, to this day no internationally accepted standard exists for the determination of SEM resolution. Further, to confuse matters ...

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.

An AI algorithm converts 2D electron microscope images into accurate 3D structures, cutting analysis time and cost to one-eighth while preserving precision. The newly developed algorithm requires ...
