Schematic representation of the experimental setup: Attosecond pulses (violet) eject electrons (green) from a crystal surface. The photoemission electron microscope (cone-shaped instrument at top) ...

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 ...

Chemists discover how key contrast agent works, paving a way to create new markers needed for correlative microscopy that can image the structure and signaling of cells at the same time. Two labs at ...

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 ...

What is Cryo-Electron Microscopy? Cryo-electron microscopy (cryo-EM) is a powerful technique used to determine the three-dimensional structure of biological macromolecules, such as proteins and ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...
