This invention relates to the field of sensing materials technology, specifically disclosing a cellulose-based conductive hydrogel material for ascorbic acid detection, its preparation method, and its applications. This hydrogel uses TEMPO oxidized cellulose nanofibers (TOCNF) as a biocompatible matrix. By introducing Cu-BTC / CNT composite nanoparticles, a three-dimensional conductive network with both high electrochemical activity and structural stability is constructed. While retaining the biocompatibility and flexibility of cellulose, it exhibits particularly high sensitivity and selectivity in detecting small biomolecules such as ascorbic acid, with short response time and good stability. This method achieves synergistic optimization of the composite material's structural uniformity and functionality without relying on complex molding processes. Experimental results show that the conductive hydrogel prepared by this invention possesses good mechanical properties and biocompatibility, exhibiting high sensitivity and stability in biosensing fields such as ascorbic acid detection, providing a novel high-performance material basis for flexible biosensors.

This invention discloses a fuel cell cycle system and its control method based on high-frequency pulsed coordinated ejection. The system includes a hydrogen inlet pipeline, an ejector, a fuel cell stack, a vapor-liquid separator, and a tailpipe valve. The hydrogen inlet pipeline includes a hydrogen inlet solenoid valve, a proportional valve, and a pulse solenoid valve. These valves are sequentially connected to the hydrogen inlet of the ejector. The hydrogen outlet of the ejector is connected to the hydrogen inlet of the fuel cell stack, and the stack's outlet is connected to the liquid-vapor mixture inlet of the vapor-liquid separator. The hydrogen return port of the ejector is connected to the separation outlet of the vapor-liquid separator. The liquid outlet of the vapor-liquid separator is connected to the tailpipe valve. The hydrogen inlet pipeline is connected to a hydrogen source. This invention improves battery performance consistency, suppresses performance degradation, and enhances system reliability and stability by creating a sufficient pressure differential to drive hydrogen circulation.

This invention relates to the field of pharmaceutical preparation technology, specifically to a sulfachlorpyridazine sodium-methotrexate suspension, its preparation method, and its application. The sulfachlorpyridazine sodium-methotrexate suspension of this invention comprises the following components per 100 ml: 20-50 g of sulfachlorpyridazine sodium, 4-10 g of methotrexate, 0.1-0.25 g of suspending agent, 0.05-0.125 g of wetting agent, 0.2-0.5 g of antioxidant, 0.1-0.25 g of disodium edetate, and purified water to a final volume of 100 ml. The suspension prepared by this invention can delay the in vivo clearance of sulfachlorpyridazine sodium, prolong the synergistic effect time, and improve its bioavailability; in the treatment of coccidiosis infection in chickens and sheep, it can significantly improve weight gain, reduce intestinal lesion values, rapidly clear oocysts, and maintain a long-lasting protective effect after drug withdrawal.

This invention relates to the field of composite material preparation technology, specifically to a method for preparing continuous glass fiber reinforced polyurethane core profiles, comprising the following steps: preparing continuous glass fiber, isocyanate component, polyol component, chain extender, coupling agent, catalyst, antioxidant, and ethanol, wherein the isocyanate index of the isocyanate component and the polyol component is 0.8-1.1. This invention effectively solves many defects of existing technologies by constructing a multi-dimensional synergistic optimization system, possessing significant technical advantages and practical value. Regarding interfacial bonding, a composite modification method is adopted, which significantly improves the interfacial bonding strength between the fiber and the polyurethane matrix, fundamentally improving the conduction efficiency of the material's mechanical properties, resulting in a significant improvement in the material's core mechanical properties such as tensile, bending, and impact resistance.

The application provides a photothermal-water-voltaic synergistic effect wide-spectrum plasmonic core-shell material and a device preparation method. In the synthesis process, anisotropic plasmonic nanostructures respectively undergo aggregation in a plane and overlap in a vertical direction, which respectively causes red shift and blue shift of a surface plasmon resonance (SPR) resonance peak, and breaks through the diffraction limit to achieve wide-spectrum absorption. The thin film prepared by the application has good photothermal effect, and the existence of the oxide shell can effectively protect the plasmonic metal core from deformation caused by chemical reaction with the outside world when the temperature rises. In addition, the prepared thin film has good water-voltaic power generation capacity, and can improve the water-voltaic power generation output by using the photothermal effect under illumination.
