Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...

On the birefringence of rods and cones [PDF]
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 ...

Supramolecular Liquid Crystal Elastomer Adhesives: Role of Internal Damping and Hydrogen Bonding
The adhesion strength can be significantly enhanced through the molecular design of supramolecular liquid crystal elastomers (LCEs) that combine high internal damping from mesogen reorientation with abundant hydrogen‐bonding moieties. Solvent vapor annealing enables reversible, non‐thermal control of adhesion, offering potential for heat‐sensitive ...

Phase-matching-induced near-chirp-free solitons in normal-dispersion fiber lasers
The fiber birefringence, chromatic dispersion, and nonlinear effect follow a phase-matching principle, enabling the formation of birefringence-managed solitons in normal-dispersion fiber lasers containing a section of polarization-maintaining fiber.

Imaging polarimetry for the determination of stress constraint in transparent solids
Using a Mueller matrix polarimeter based on liquid crystal cells [1] and the forward polar decomposition [2], we study the evolution of the birefringence property induced by an increasing compression of a Plexiglas sample.

Long-Time Relaxation of Stress-Induced Birefringence of Microcrystalline Alkali Halide Crystals
Alkali halide single crystals are most commonly used as the diluent matrix in the tablet method or disk technique for spectroscopic measurements. However, stress-induced birefringence (SIB) of alkali halides as well as intrinsic birefringence manifest ...

Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.

Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...
