Summary: The study focused on the structural relaxation kinetics of lead metasilicate glass, showing that the structural relaxation process is not controlled by isostructural viscosity and equilibrium shear viscosity only provides a lower boundary for structural relaxation kinetics.

Summary: An anti-resonant hollow-core fiber capable of propagating the LE'11 mode with high purity and over a wide wavelength range is proposed and demonstrated. The suppression of the fundamental mode relies on the resonant coupling with specific gas selectively filled into the cladding tubes. After a length of 2.7 m, the fabricated fiber shows a mode extinction ratio of over 40 dB at 1550 nm and above 30 dB in a wavelength range of 150 nm. The loss of the LE'11 mode is measured to be 2.46 dB/m at 1550 nm. We discuss the potential application of such fibers in high-fidelity high-dimensional quantum state transmission.

Summary: Patterned structures in PeLEDs, such as the SiO2-microcolumn pattern, can reduce optical loss and improve the external quantum efficiency. The increase in the number of patterned interfaces contributes to a decrease in optical loss, thanks to the scattering effect and the utilization of waveguide and surface plasmon polariton modes. A PeLED with a five-interface structure based on an SMP substrate demonstrated improved light outcoupling, suggesting a synergistic design for efficient devices with multi-interface patterns.

Summary: The Unruh effect, a fascinating aspect of quantum fields in curved spacetime, remains a challenge for direct experimental detection of Unruh temperature. Gradient optical waveguides are proposed to achieve high effective Unruh temperature, but experimental realization is yet to be reported. This study uses a tapered fiber to simulate accelerated motion and obtains effective Unruh temperature, showing a dependence of leaky radiation on photon acceleration.

Summary: A dielectric/Ag-coated hollow fiber (HF) temperature sensor based on long-range surface plasmon resonance (LRSPR) is proposed and experimentally demonstrated. The sensor achieves a temperature sensitivity of 3.6 to 20.5 nm/℃, which is one of the highest reported among optical fiber temperature sensors. The detection range of the sensor can be easily tuned up to 170℃, offering an outstanding advantage compared to temperature sensors using polydimethylsiloxane.

Summary: This study investigates the influence of material dispersion on the scattering performance of nanoparticles for daylight radiative cooling. It reveals that nanoparticles with similar responses at visible frequencies exhibit fundamentally different scattering properties at infrared frequencies due to material dispersion. These dispersive nanoparticles show suppressed-scattering windows, enabling selective thermal emission within a highly reflective sample. The existence of suppressed-scattering windows depends solely on material dispersion and remains fixed at the same wavelength even in random composite materials and periodic metasurfaces. Additionally, calcium-silicate-hydrate (CSH), the main component of concrete, is explored as an example of a dispersive host, showing that the co-design of nanoparticles and host material allows for tuning of the suppressed-scattering windows. The results suggest that controlled nanoporosity can enable concrete with passive radiative cooling capabilities.

Summary: The interferometric particle imaging (IPI) technique uses scattered light's angular oscillations for droplet or bubble sizing by evaluating refractive index and extracting particle diameter from interferogram images. This method, utilizing two CCD cameras at different scattering angles, was validated with water droplets and glycerol droplets suspended in air.

Summary: The release of ferulic acid from surface-functionalized hollow nanoporous silica particles (HNSPs) was studied. HNSPs were synthesized in the presence of polymer and surfactant templates, and the pores and surfaces were modified through silane coupling reactions. The release rates in DI water and ethanol were highest for HNSP, followed by PTS-HNSP, and lowest for OTS-HNSP.

Summary: A new approach is proposed to conquer the thermal phase drift of fiber-optic Fabry-Perot interferometer (FPI) sensors. By using a hollow-core anti-resonant fiber and optimizing the fusion splicing between the lead-in single-mode fiber and the hollow-core anti-resonant fiber, a high spectral resolution FPI sensor is constructed. The thermal phase drift of the FPI is eliminated by connecting the FPI air cavity to the external environments, leading to improved measurement accuracy and detection limit.

Summary: A one-step etching method was used to prepare hollow silica nanospheres (HSNs) with controllable morphologies and low refractive index (<1.15). The obtained HSNs were then deposited into coatings to design a double-layer broadband antireflective coating with excellent transmittance, antifogging property and weather durability.

Summary: The determination of sample size is crucial in forensic analysis of glass using refractive index (RI), and it is inversely related to the variance of RI across the glass source. A study on 218 tempered vehicle windows found similar within-source and within-fragment variances, suggesting potential increased homogeneity in modern glass. Simulation studies showed that using nine RI measurements instead of three yielded a lower false exclusion rate, while the false inclusion rate remained relatively stable regardless of recovered glass sample size.

Summary: A straightforward synthetic strategy using Suzuki-Miyaura/Scholl tandem reactions was employed to synthesize new series of annulated pi-extended poly-(hetero)aromatic hydrocarbons with carbazole, fluorene, and fluorenone central building blocks. The resulting compounds demonstrated strong aggregation tendencies in organic solvents and exhibited a wide range of liquid crystal phases, as well as high fluorescent quantum yields and excellent photocurrent behavior. This approach provides a potent and resilient method for the fabrication of various heteroarene molecular systems with potential applications in organic semiconductors and electroluminescent materials.
