Non-reciprocal magneto-optics memory enables an integrated photonic platform that supports powerful matrix-vector multiplication computing and fast, efficient, fatigue-free programming capabilities.

Picco et al experimentally validate an optimisation method for reservoir computers in which a delayed version of the input is provided. Their approach, validated on several benchmarks, improves performance and facilitates hyperparameter tuning.

Drawing inspiration from neural architectures, the customized cross-linking density in shell materials of perovskite/polymer nanosphere enables advanced multi-dimensional sensing and interaction.

A finer understanding of complex mechanisms governing Li-ion batteries performance demands operando techniques. Here, the authors combine fibre-optic infrared spectroscopy with multivariate regression chemometrics to reveal the dynamics and composition of the solid electrolyte interphase.

Metal halide perovskite solar cells are emerging as next-generation photovoltaics, offering an alternative to silicon-based cells. This Primer gives an overview of how to fabricate the photoactive layer, electrodes and charge transport layers in perovskite solar cells, including assembly into devices and scale-up for future commercial viability.

Non-reciprocal magneto-optics memory enables an integrated photonic platform that supports powerful matrix-vector multiplication computing and fast, efficient, fatigue-free programming capabilities.

Achiral dielectric nanostructures provide an efficient method for discriminating left- and right-circularly polarized photons, leveraging the photothermoelectric effect.
