To optimize Transmission Electron Microscopy (TEM) and Scanning Transmission Electron Microscopy (STEM) imaging, the acquisition of different signals at varying accelerating voltages for ...

Electrically pumped semiconductor lasers are among the most important sources owing to their high efficiency, compactness, and solid-state stability. For the mid-infrared and terahertz radiations, ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening the door to atom-specific analysis and control. (Nanowerk Spotlight) ...

Direct exoplanet spectroscopy aims to measure the spectrum of an exoplanet while simultaneously minimizing the light collected from its host star. Isolating the planet light from the starlight ...

What is Fluorescence Correlation Spectroscopy (FCS)? Fluorescence correlation spectroscopy (FCS) is a powerful analytical technique that enables the study of dynamic processes and interactions at the ...
