Tailoring Optical and Vibrational Properties by Bond Confinement: The Case of Metavalent Chalcogenide and Pnictogen Thin Films

open access: yesAdvanced Optical Materials, EarlyView.
This perspective explores how intrinsic confinement effects in metavalent chalcogenide and pnictogen thin films alter optical and vibrational properties. By comparing thickness‐dependent effects across prototypical systems, this work highlights the role of unconventional bonding in shaping coherent phonon dynamics and dielectric functions, offering new

An Efficient Diamond Raman Amplification Scheme Based on Adaptive Temporal Synchronization

open access: yesAdvanced Photonics Research, EarlyView.
This work reveals an adaptive temporal synchronization effect in delayed diamond Raman amplification, where the Stokes pulse shifts toward the fundamental peak. A periodic amplification scheme based on this phenomenon enables efficient pump recycling and enhanced energy conversion, offering a robust, delay‐tolerant strategy for advanced nonlinear ...

Precision Diagnostics in Sports‐Related Traumatic Brain Injury: Pathophysiology, Biomarker Development and Emerging Technologies

open access: yesAdvanced Sensor Research, EarlyView.
Sports‐related traumatic brain injuries (TBIs) remain underdiagnosed, within amateur athletic cohorts. This review critically synthesises recent advancements in AI‐assisted neuroimaging, blood‐based biomarker profiling, wearable biosensing platforms for early detection, injury stratification, and longitudinal surveillance of TBIs.

Van der Waals Template‐Assisted Growth of Two‐dimensional Sb2S3

open access: yesAdvanced Science, EarlyView.
Van der Waals (vdW) template‐assisted growth of atomically thin two‐dimensional (2D) Sb2S3 on monolayer MoS2 single crystals is demonstrated, overcoming its thermodynamically preferred one‐dimensional (1D) growth. The resulting sub‐8 nm nanosheets show uniform coverage, atomically sharp interfaces, and enhanced broadband optoelectronic performance as ...

Kinetically Controlling Surface Atom Arrangements in Thermally Robust, Amorphous High‐Entropy Alloy Nanoparticles by Solvent Selection

open access: yesAdvanced Science, EarlyView.
This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...
