A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

Hyperentanglement in Nanophotonic Systems With Discrete Rotational Symmetry

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
This work introduces a nanophotonic scheme leveraging discrete rotational symmetry to unlock two quantum capabilities: generation of hyperentangled photon pairs in spin and spatial degrees of freedom; and isomorphic mapping that preserves free‐space degrees of freedom, overcoming the information loss in non‐paraxial photonic systems.

Turbulence‐Resilient Coherent Receiver Array on CMOS‐Compatible Silicon Photonics for Free Space Optical Communications

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
A CMOS‐compatible silicon‐photonic 4 × 4 coherent receiver array spatially samples turbulence‐distorted wavefronts and, with maximum‐ratio combining, enables signal recovery. Experimental BPSK tests under moderate turbulence approach theoretical combining efficiency, reducing BER from 1E‐2 to 1E‐15.

Active Switching of Orbital Angular Momentum of Light Using Metasurfaces Incorporating Vanadium Dioxide

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
This work presents a novel design strategy for active metasurfaces that actively switches OAM modes. The metasurface integrates VO2 within MIM meta‐atoms. Operating at 1500 nm, the designed platform enables large leaps in topological charge. For instance, the reflected beam can be switched from a topological charge of −1 in the insulating (M1) phase to
