Optical and scanning electron microscope images of a nano-LED device that uses AC power instead of DC power, which could be a game-changer for sharper near-eye displays. Journalists may use this image ...

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic ...

a) Photograph of HV precipitates collected from the Shinkai Seep Field. b) Cross-polarized optical microscope images of precipitates in cross section. c,d) Scanning electron images showing layers ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...
