The properties of a surface are influenced not only by its chemical composition but also by its topographical structure. Nature presents several examples where both characteristics are controlled, for ...

Raman microscopy combines optical microscopy with the ability to determine the chemical makeup of surfaces. Laser light is delivered to the sample surface via the same objective as the optical light ...

Ultrafast electron microscopy (UEM) and ultrafast electron diffraction (UED) employ extremely short electron pulses—ranging from picoseconds down to a few femtoseconds—to image and diffract samples ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...
