Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Virtual Horizons in Medicine: The Role of the Metaverse in Transforming Medical Education—A Qualitative Scoping Review

open access: yesHealth Science Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background The metaverse is defined as a three‐dimensional, interactive and persistent virtual space in which users interact with one another and with simulated environments through digital avatars. This technology, as an innovative approach to education and learning, holds transformative potential for medical education.

Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

open access: yesJournal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

open access: yesLaser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Amphiphilic Motif Triggers Microheterogeneity in Low‐Melting Mixtures

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
Alkylated cholinium iodides are synthesized and mixed with ethylene glycol, resulting in low‐melting mixtures (LMMs). Ammonium alkylation induces amphiphilicity and drives nanoscale segregation into charge‐rich and charge‐poor domains. Combined spectroscopic, scattering, and computational analyses reveal how headgroup alkylation and counterion effects ...

Near‐White Circularly Polarized Luminescence by Color Mixing Utilizing Surface‐Fluorophore‐Modified Cellulose Nanocrystals in Composite Films

open access: yesChemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (

Radio‐Frequency Front‐End‐Free Hybrid Code‐Division and Space‐Division Wireless Multiplexing Using Space‐Time‐Coding Metasurface

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
This work constructs a radio‐frequency front‐end‐free hybrid code‐division and space‐division‐multiplexing wireless communication system built on programmable space‐time‐coding metasurfaces. Orthogonal pseudo‐random codes reliably separate overlapped multistream signals that share identical frequency, time, and spatial resources.
