Summary: The design of ratiometric fluorescence probes with large Stokes shift is of great significance in detecting and imaging target substances in complex organisms. In this study, a novel fluorophore with a large Stokes shift was easily obtained, and a fluorescence probe based on it demonstrated rapid response, high selectivity, and sensitivity towards peroxynitrite. The probe also showed excellent biocompatibility and remarkable mitochondrial targeting ability, making it suitable for proportional imaging of peroxynitrite in living cells and zebrafish.

Summary: This paper investigates the structure and mechanism of nitrogen-containing NTIL molecules using the example of triethylamine (TEA). It is found that oxygen molecules induce weak hydrogen bonding and n-pi electron conjugation between TEA molecules, resulting in the formation of NMIDLINE HORIZONTAL ELLIPSISO clusteroluminogens. This structure explains why nitrogen-containing NTIL substances exhibit bright fluorescence when exposed to oxygen molecules and has implications for understanding tissue biofluorescence from oxidative folding of proteins.

Summary: This study successfully utilizes a natural fiber-based waste, wood apple dust (WAD), as a potential filler material in epoxy matrix. The physical and mechanical properties of epoxy-WAD composites are analyzed. The effects of filler contents on the wear behavior are studied using design of experiment. The wear rate of WAD/epoxy composites is predicted using finite element method. Epoxy/WAD composites can be used for lightweight building materials and automobile components.

Summary: In this study, lactic acid was prepared from waste biomass Pueraria cellulose through chemically catalyzed conversion. A lignin-based carbon solid acid catalyst was obtained by modifying the carbonaceous support with Al and Zn chlorides. The optimal catalyst was identified, and the reaction conditions were optimized to achieve high conversion rate and yield of lactic acid. This research provides a new pathway for the preparation of chemicals from cellulose.

Summary: Bisneopentyl glycol dithiocarboxyphosphate (DDPS) was modified by coating sulfonated melamine formaldehyde resins onto its surface, resulting in the formation of intumescent microcapsule DDPS (MDDPS). MDDPS was then incorporated into viscose fiber spinning solution to prepare flame retardant MDDPS/viscose fiber. The MDDPS/viscose fiber exhibited improved flame retardant efficiency and maintained mechanical properties.

Summary: A two-step NaOH/Na2S2O4 method was proposed to improve the decolorization efficiency of reactive-dyed cotton fabric. The decolorization mechanism of NaOH and Na2S2O4 was investigated, and it was found that Na2S2O4 decolorized the fabric more quickly than NaOH. The two-step method reduced the ineffective decomposition of Na2S2O4, resulting in a 16% higher CIE L value and retention of about 90% of the fabric's breaking strength.

Summary: This study focused on the development of biodegradable alternatives to nonbiodegradable food packaging materials. Polyvinyl alcohol (PVA) was used as the substrate and blended with zinc oxide nanoparticles (ZnONPs) and titanium dioxide nanoparticles (TiO2NPs) to prepare fiber membranes with high strength and UV blocking properties for grapes preservation. The addition of ZnONPs and TiO2NPs significantly increased the tensile strength of the PVA fiber membranes. The PVA/ZnO composite membranes exhibited superior UV absorption compared to the PVA/TiO2 composite membranes. TG tests showed that ZnONPs decreased the thermal stability of the fiber membranes, while TiO2NPs improved the thermal stability. Both composite membranes effectively extended the shelf life of grapes, with the PVA/ZnO composite membranes being more effective at maintaining freshness. The prepared composite membranes were biodegradable, contributing to the mitigation of environmental pollution caused by nondegradable plastics.
