What would it take to watch an electron move through a material? Researchers would need to see individual atoms and capture an electron's motion at incredibly short timescales. A Technion-led team has ...

Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light ...

Light and scanning electron microscopy have revealed the detailed structure of the midgut and Malpighian tubules of the ...

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 1950s, scanning electron microscopes ...

If you want to build semiconductors at home, it seems like the best place to start might be to find a used scanning electron microscope on eBay. At least that’s how [Peter Bosch] kicked off his ...

Since the first transmission electron microscope was sold in 1935, microscopes that use electrons--rather than light waves--to image objects have brought into focus levels of detail that were ...
