Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
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).

Beating the Standard Quantum Limit With Single‐Photon‐Added Coherent States

open access: yesAdvanced Physics Research, Volume 5, Issue 10, October 2026.
The standard quantum limit (SQL) defines how quantum fluctuations of light constrain measurement precision. Here, we show that injecting a single‐photon‐added coherent state and a weak coherent state in the input ports of a Mach–Zehnder interferometer reduces phase uncertainty below the SQL.

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, Volume 5, Issue 10, October 2026.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

The Fierce Morphological Battle of Silver Nanoparticles: How Irregularities, Vacancies and Defects Tip the Crossing Sizes

open access: yesSmall, Volume 22, Issue 56, 8 October 2026.
The silver nanoparticle morphologies are identified thanks to ab initio models, including original families of defects and complex motifs, compared to measurements provided at targeted sizes (309, 561, 742, and 923 atoms). The crossings between structures to within a few atoms have been predicted due to very accurate computational conditions, which are
