Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...

A new method enables calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice. The new method ...

Technique allows better imaging of microdroplets; method being used to analyze plastic nanoparticles and in virus assaying. Microscopy of microdroplet volume and nanoplastic concentration. Measuring ...
