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 ...

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.

Using machine learning to guide microscopes could reveal greater insights into the brain's connectome and deepen our ...

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 ...

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

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...

Under the right circumstances, electrons can actually “freeze” into a bizarre solid form. Now, physicists at Berkeley Lab have created and taken the first ever direct images of this structure. At low ...

They can image a wide range of materials and biological samples with high magnification, resolution, and depth of field, thereby revealing surface structure and chemical composition. Industries like ...
