Article Abstract
In this study, we successfully synthesized rare-earth-doped crystalline SrWO at room temperature by co-precipitation. The results from the X-ray diffraction analysis showed a main diffraction peak related to the (112) plane. Phosphors doped with either Dy or Sm ions showed strong light absorption in the UV region and blue-yellow and red light emission. To synthesize a white light phosphor, Dy and Sm ions were co-doped to produce a SrWO:[Sm]/[Dy] phosphor. When the Sm ion concentration was increased and the Dy concentration was maintained, the red light intensity increased while the blue-yellow light intensity decreased. The composites were combined with polydimethylsiloxane (PDMS), and a flexible composite material was fabricated. The composite exhibited various luminescence properties under UV and visible light, which suggested its potential for use as an LED color filter.

rev-Gelatin: A Gelatin with Reverse Thermo-Responsive Behavior Inspired by Candy and Ice Cubes Phase Dynamics.

Conventional gelatin's gel-to-sol transition upon heating restricts its utility in biomedical applications that benefit from a gel state at physiological temperatures such as Pluronic F127 and poly(NIPAAm). Herein, we present "rev-Gelatin", a gelatin engineered with reverse thermo-responsive properties that undergoes a sol-to-gel transition as temperature rises from ambient to body temperature. Inspired by the phase dynamics of common materials like candy and ice cubes, whose surfaces soften or partially melt under warming, facilitating inter-object adhesion- rev-Gelatin leverages this concept to achieve fluidity at room temperature for easy injectability.

The separation and propagation of spin are vital to understanding spin-orbit coupling (SOC) in quantum systems. Exciton-polaritons, hybrid light-matter quasiparticles, offer a promising platform for investigating SOC in quantum fluids. By utilization of the optical anisotropy of materials, Rashba-Dresselhaus SOC (RDSOC) can be generated, enabling robust polariton spin transport.

The construction of polymer-based photoactivated room-temperature phosphorescence systems remains a prominent research focus, yet the development of ultrafast activated systems under ambient conditions continues to pose a challenge. In this study, cyclized phenothiazine derivatives bearing diverse substituents are synthesized and incorporated into an amorphous polyvinyl alcohol (PVA) matrix, resulting in significantly enhanced dynamic photoactivation characteristics compared with those of their pristine monomeric counterparts. Under ambient conditions and 2 s irradiation, the lifetime and quantum yield of C[4]PTZ-OH@PVA increase by factors of 1.

This study examined quality changes in () stingless bee honey subjected to thermal treatment and stored at room temperature. Honey was heated at 55, 75, and 90 °C for 10 or 20 min and then stored at 30 °C for 40 days. Physicochemical parameters including moisture content, total soluble solids (TSS), pH, acidity, viscosity, hydroxymethylfurfural (HMF), color (L*, a*, b*), antioxidant activity, and total phenolic content were analyzed.
