Zero Birefringence and Zero Birefringence Dispersion in 3 µm-thick Silicon-on-Insulator Waveguides [PDF]
In this study, effective index birefringence and group index birefringence are investigated for 3 µm-thick silicon-on-insulator (SOI) strip waveguides, and experimental results are compared with simulations.

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement
Angewandte Chemie, EarlyView.Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Models for cosmic birefringence [PDF]
openParity violation allow us to investigate some processes that took place in the early Universe, and to shed light on new physics beyond the Standard Model. We will analyze one of the effects that generate this violation: the Cosmic Birefringence (CB).

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair
Advanced Science, EarlyView.A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Birefringent properties of the human cornea in vivo : towards a new model of corneal structure [PDF]
The fundamental corneal properties of mechanical rigidity, maintenance of curvature and optical transparency result from the specific organisation of collagen fibrils in the corneal stroma. The exact arrangement of stromal collagen is currently unknown

Advanced Science, EarlyView.Reverse Weak Polarity‐Induced Ordered Layer Control strategy, optimizing the design of layered structures, has been successfully designed. By leveraging inhomogeneous field of units to replace isotropic fields of metal cations, polar layers realize controllable layer stacking via a “layer→linker→layer” polarity transfer.
