Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

This stretchable active frequency selective fabric achieves reversible switching between bandstop and transparent states through strain‐induced reconfiguration of its conductive network. Its zero‐power and mechanically tunable characteristics offer potential for wearable electromagnetic functional materials.

A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.
