Investigating the operation mechanism of light-emitting electrochemical cells through operando observations of spin states

Light-emitting electrochemical cells are next-generation light-emitting devices but the operation mechanism is still not well understood microscopically. Here, the operation mechanism of light-emitting electrochemical cells is microscopically investigated by operando observation of spin states.

CASPI: collaborative photon processing for active single-photon imaging

The sparse, noisy, and distorted raw photon data captured by single-photon cameras make it difficult to estimate scene properties under challenging illumination conditions. Here, the authors present Collaborative photon processing for Active Single-Photon Imaging (CASPI), a technology-agnostic, application-agnostic, and training-free photon processing pipeline for high-resolution single-photon cameras.

Using surface plasmons to create programmable neural networks

A spoof surface plasmonic neural network with programmable weights and activation functions was proposed, which has the potential to achieve processing speeds close to the speed of light. This neural network was used to create a wireless communications system that can detect and process electromagnetic waves.
