Dielectric‐Confinement‐Induced in‐Plane Photoelectric Anisotropy in Isotropic Quasi‐1D γ‐GaS Nanoribbon

Advanced Science, EarlyView.
We investigate the geometry‐governed optoelectronic anisotropy arising from dielectric confinement in quasi‐1D γ‐GaS nanoribbons with intrinsically isotropic atomic structures. Dielectric mismatch between the nanoribbon and its surroundings leads to a general polarization‐dependent photoresponse during near‐field scattering.

Two-Layer Polarization-Maintaining Solid-Core Photonic Crystal Fiber

IEEE Photonics Journal, 2018
In this study, a two-layer polarization-maintaining solid-core photonic crystal fiber (SC-PCF) is proposed. The cladding has two large holes both in the first and second layers for high birefringence and confinement loss reduction, respectively.

On the birefringence of rods and cones [PDF]

Pfl�gers Archiv European Journal of Physiology, 1971
Measurements were made of the birefringence of bleached rods and cones of six non-mammalian vertebrates. The variables included fixatives and temperature, and the immersing medium namely ethyl alcohol, urea, type of Ringer solution, and sucrose. The temperature variations of the birefringence of rods and cones were similar in frogs and in goldfish ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates
