Healthy cells are constantly breaking down proteins and building up new ones with the help of enzymes aptly named unfoldases, because they unravel proteins tagged for destruction or recycling. Now, a ...

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 ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

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 ...

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.

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 ...

Researchers at the University of Arizona have developed the world's fastest electron microscope that can capture the movement of electrons. They believe their work will lead to groundbreaking ...

Princeton scientists are peering into the smallest corners of matter using an exceptional collection of sophisticated microscopes — some so big they fill a room. These remarkable instruments have ...
