Fifteen years ago, physicists worked out a method to increase image contrast by hitting the electron imaging beam with an ...

Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

If you picture an electron breaking free from a solid, the process seems simple. Give it enough energy, and it should blast off into space. But a team of researchers from TU Wien and their colleagues ...

From paints and inks to catalysts and drug-delivery materials, many advanced technologies rely on substances dispersed in ...

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 ...

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 ...

The FEI 200kV Titan Themis Scanning Transmission Electron Microscope (STEM) is a scanning transmission electron microscope with several key capabilities. This microscope positions Michigan Tech ...

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 ...
