Have you ever wondered what makes shark skin so tough and sleek? It's dermal denticles—tiny, tooth-like structures that cover a shark's skin. Made of the same material as teeth and shaped like small ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

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.

Scanning electron microscopy (SEM) traditionally yields high-resolution two-dimensional micrographs, leaving surface topology and depth information inaccessible. Three-dimensional reconstruction ...

What really happens when a blade cuts through metal? An engineer builds a custom device capable of cutting aluminum inside a scanning electron microscope, then captures approximately 70 images over a ...

Today we are machining some metal inside the scanning electron microscope! By creating a custom fixture, we can manually ...

Unlike optical microscopy, SEM does not rely on light waves but instead uses a beam of electrons to interact with materials, enabling magnifications up to 300,000× and resolutions approaching 1 nm. 1 ...
