Summary: Mold is an important indicator of wheat quality, as it decreases the quality of wheat kernels and produces harmful secondary metabolites. Traditional detection methods for wheat mold are complex and wasteful. This paper proposes an eco-friendly and nondestructive detection method based on ultra weak luminescence. By measuring ultra weak luminescence signals and using approximate entropy and multiscale approximate entropy as classification features, a support vector machine detection model is established, achieving a high classification accuracy rate.

Summary: Nanofiber Bragg cavities (NFBCs) can be tuned to a resonance wavelength by applying mechanical tension, and this tunability is important for matching the emission wavelength of single-photon emitters. In this study, the ultra-wide tunability and the limitation of the tuning range of NFBCs were analyzed using 3D finite element method (FEM) and 3D finite-difference time-domain (FDTD) optical simulations. The simulations showed that both the elongation of the grating period and the small shrinkage of the diameter contributed to the ultra-wide tunability of NFBCs.

Summary: Modern medicine is seeking new, more gentle, and efficient diagnostic methods, with studies finding a connection between reactive oxygen species and pathological states in organisms. The phenomenon of biological autoluminescence may serve as a non-invasive tool for monitoring oxidative stress during diseases. Analysis of yeast helped establish the relationship between reactive oxygen species and autoluminescence intensity, contributing to real-time monitoring of oxidative processes in biomedicine and biotechnology.

Summary: Traditional Chinese medicine (TCM) has unique advantages in the prevention and treatment of type 2 diabetes (T2DM), and a novel method using ultra-weak photon emission (UPE) was developed to evaluate the therapeutic effect of TCM. The UPE intensity decreased gradually with the treatment, and the ratio of photon counts between specific wavelength ranges negatively correlated with syndrome scores, indicating the degree of symptom improvement.

Summary: This article describes the effects of multiple nonlinear Compton scattering on electrons in ultra-strong fields using analytic formulas similar to those in the theory of multiple bremsstrahlung. Based on these formulas, a new pure quantum effect called quantum peak splitting is identified, where the electron peak splits into two when the average number of nonlinear Compton scatterings per electron reaches 5.1 and is below 9. This effect provides a new mechanism for the formation of electron peaks, imposes a new beamstrahlung limit on future colliders, and corrects the picture of quantum radiation reaction.

Summary: This study proposes a method that combines skull optical clearing (SOC) technique and three-photon fluorescence microscopy (3PM) to overcome the scattering effects of the skull and brain tissue, enabling observation of deep microvasculature and neuronal structures. By using visible-NIR-II compatible skull optical clearing agents and a bright aggregation-induced emission (AIE) nanoprobe with large three-photon absorption cross section, the researchers achieved the largest cerebrovascular and neuronal imaging depth to date.

Summary: A model for mercury transformations in a flue gas treatment process was established in this study. Concentrations, mass flow rates, and emission factors of mercury, NOX, PM, and SO2 were investigated in a coal-fired power plant. The mercury removal efficiency of different units, such as the SCR unit, ESP, and WFGD, were also analyzed. The proposed flue gas treatment process model is considered a feasible approach for quantitative evaluation of multi-pollutants emissions at plant level.

Summary: Introducing Fe3+ Lewis acid sites into TiO2 ultra-thin nanosheets can significantly enhance the photocatalytic activity. The Lewis acid sites trap photo-generated electrons and promote the O-2 reduction process through charge imbalance. Additionally, oxygen defects near Lewis acid sites facilitate the adsorption, activation, and oxidation of water molecules. The photo-redox reaction occurs simultaneously around the Lewis acid sites, driving the photocarriers' transmission and separation.

Summary: The study demonstrates that iron oxide/titania heterostructures exhibit efficient removal of AsH3 under UV light, with good humidity stability and water resistance. The superior room temperature catalytic activity for AsH3 removal can be attributed to the light-induced formation of highly active oxygen species and enhanced desorption of adsorbed water.
