Bird songs differ widely among species and can show peculiar phenotypes, such as extreme or unusual sound frequencies for a species' body size. Although birds can modulate sound frequency, size-related limitations prevent vocalizing efficiently (i.e.

Antimony selenide (SbSe), a narrow-bandgap semiconductor with strong light absorption, exhibits photoresponse up to ≈1050 nm due to its intrinsic 1.15 eV bandgap. To extend detection into the near-infrared (NIR, 700-1350 nm), Bi-alloyed (BiSb)Se is developed via vacuum sputtering and postselenization.

Helicene-based circularly polarized luminescence (CPL) materials suffer from severely low color purity in circularly polarized organic light-emitting diodes (CP-OLEDs). Here, a novel molecular engineering strategy is introduced by replacing helicene containing continuous fused benzene rings with a multiple resonance (MR) framework comprising discontinuous fused benzene rings. This approach effectively suppresses high-frequency C─C bond stretching vibrations and enhances short-range charge transfer, enabling high color purity, CPL activity, and efficient thermally activated delayed fluorescence (TADF).

Aim: This study aimed to analyze the disease burden of carbon monoxide poisoning (COP) in China from 1990 to 2021 and to forecast future trends.
Methods: Data were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021. The incidence, prevalence, mortality, and Disability Adjusted Life Years (DALYs) and their corresponding Age-Standardized Rates (ASRs) were examined to assess the burden of COP in China from 1990 to 2021.

Polymer-derived ceramics are a versatile class of multifunctional materials synthesized the high-temperature treatment of a preceramic polymer. In this work, we report the synthesis of a vanadium carbide-embedded carbonaceous hybrid by pyrolyzing a modified preceramic polymer incorporating vanadium acetylacetonate in a polysilsesquioxane followed by hydrofluoric acid etching. The structural and microscopic characterisation confirmed the uniform distribution of nanoparticulate vanadium carbide in the matrix.
