We used fluorescence nonradiative energy transfer (NRET) to detect the interchain distances r at the overlapping regions of polymer chains. Freeze-dried polystyrene (PS) is found to have an increased ...

A 256×256 CMOS passive pixel image sensor with especially equipped simple switches, which enables motion detection, is implemented. Each pixel consists of a simple combination of a photodiode and an ...

Many animals rely on visual motion to infer their relation to the surrounding environment while moving around in it. Motion processing in biological nervous systems, particularly in the insects, has ...

Two-dimensional (2D) materials hold great promise for high-performance photonic chip-integrated photodetectors, thanks to their outstanding electronic and optical properties as well as ...
