Reconfigurable Circularly Polarized Terahertz Emission from vdW Ferroelectric NbOI2

Laser &Photonics Reviews, EarlyView.
A controllable chiral terahertz pulse can be generated using a simple dual‐flake vdW ferroelectric NbOI2 emitter in which the polar axes of the two NbOI2 flakes are orthogonal. Both the chirality and the ellipticity can be manipulated by varying the separation distance and the orientations of their polar axes.

An Optimized Staining Method for Visualization of Thermally Denatured Dermal Collagen

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Background and Objectives Accurate visualization of thermal damage zone (TDZ) in the dermis is critical for energy‐based device (EBD) and burn research. While nitroblue tetrazolium chloride (NBTC) staining and birefringence imaging are commonly used, both rely on detecting loss‐of‐signal, thereby only inferring TDZ indirectly.

Ultrafast Electro‐Optical Response of Polymer‐Dispersed Liquid Crystals with Ferroelectric Nematic Liquid Crystal in Light Transmission to Light Scattering Switching

Macromolecular Materials and Engineering, EarlyView.
Polymer‐dispersed liquid crystals (PDLCs) are electro‐optical functional materials capable of switching between light‐transmitting and light‐scattering states. We successfully fabricated a PDLC for the first time using ferroelectric nematic liquid crystal (FNLC) with high polar and spontaneous polarization.

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Strain‐Induced Density Fluctuations in Glassy Polymers

Macromolecular Rapid Communications, EarlyView.
Strain deformation induces the density fluctuations in glassy polymers, resulting in shear‐thinning behavior. ABSTRACT Deformation of glassy polymers induces plastic flow as a result of mechanical instability, ultimately leading to cavitation and fracture of the liquid. Thus, understanding the origin of such mechanical instability is crucial.
