Abstract :
Nickel-cobalt bimetallic sulfides are promising electrode materials for hybrid supercapacitors due to their high theoretical capacity and abundant active sites, but their practical application is limited by poor electrical conductivity and structural instability during cycling. To address these challenges, hierarchical chrysanthemum-shaped Co3S4@Ni3S4@C heterostructures were successfully synthesized via a two-step hydrothermal method using bamboo-derived porous carbon (BNA600). The resulting Co3S4@Ni3S4@C heterostructure exhibited significantly enhanced electrochemical performance, achieving a high specific capacitance of 1016.8 F g-1 at 1 A g-1 in a three-electrode system, along with superior rate capability (80.4 % retention at 10 A g-1). Benefiting from the hierarchical porous morphology, conductive carbon matrix, and optimized electron transport pathways at the heterogeneous interfaces, the assembled hybrid supercapacitor (Co3S4@Ni3S4@C cathode and bamboo-derived porous carbon anode) delivered an ultrahigh energy density of 68.13 Wh kg-1 at a power density of 749.8 W kg-1 and maintained an outstanding energy density of 51.25 Wh kg-1 even at a high power density of 7500 W kg-1, surpassing most previously reported hybrid supercapacitors. Additionally, the device exhibited excellent cycling stability, retaining 89.2 % of initial capacitance after 5000 cycles at 20 A g-1. These results highlight the considerable potential of Co3S4@Ni3S4@C heterostructures derived from bamboo carbon for advanced electrochemical energy storage applications.

Abstract :
芳樟醇具有良好的抗菌和抗氧化性,但易挥发且热稳定性差。埃洛石纳米管(HNTs)存在特殊中空孔道结构并具有保护和释放活性物质的功能,常作为纳米载体。因此,开展HNTs负载芳樟醇(LNL)的研究并进行抗菌试验。采用真空负压法将LNL负载到3 mol/L盐酸酸化后的埃洛石纳米管(AC-HNTs)管腔内部,制备出芳樟醇-酸化埃洛石纳米管(L-AC-HNTs)新型防霉抗菌剂。以竹制品中常见的大肠杆菌(Escherichia coli)、金黄色葡萄球菌(Staphylococcus aureus)、黑曲霉菌(Aspergillus niger)、桔青霉菌(Penicillium oryzae)为目标菌种,考察不同添加量L-AC-HNTs的抑菌效果,测试其热稳定性和缓释性并进行表征分析。结果表明:添加1.5%质量浓度的L-AC-HNTs对以上几种细菌和霉菌的抑菌效果最佳,抑菌率均达到了100%。LAC-HNTs的热分解速率峰值温度达到279.9℃,比纯LNL提高了81.5℃,AC-HNTs在50℃下挥发72 h后对LNL的保留率仍为94.6%,仅损失了3.4%,而纯LNL保留率为8%,酸化刻蚀后LNL负载量从5.0%最高提升至15.6%。L-AC-HNTs具有广谱抑菌性和热稳定性,为其在竹制品中的应用提供参考。

Abstract :
Introducing dynamics into bio-based adhesives shows many advantages on rendering mechanics and functions. However, the efficient employment of dynamic chemistry in achieving robust, stable, and reusable bio-based adhesives derived from low-value residues remains elusive. Here, we facilely develop a reused camellia meal-based adhesive integrating excellent mechanical robustness, environment durability, and mildew resistance through the cooperation of dual dynamic bonds. By deliberately harnessing dynamic covalent bonds as the first strong interlinking and dynamic noncovalent bonds as the second weak interaction, our strategy allows the resulting adhesive with a much-improved adhesion strength (2.1/1.06 MPa to wood in dry/wet condition) and remarkable adhesion maintenance against harsh environmental factors (organic solvents, salt, acid, alkali, temperature, soaking time). By virtue of these abundant dynamic bonds, this adhesive not only escapes from the inherent drawback of biomaterials to display enlarged anti-mildew efficacy, but also is capable of reprocessing to gain reusability. Combining these desirous characters with the simple two-step fabrication process, this study provides a great potential for the development of high-performance bio-based adhesives sustainably and intelligently.

本发明提供了一种解聚虾蟹壳改性的低游离甲醛氨基树脂胶黏剂及其制备方法。以机械力将甲壳类动物外壳粉碎成粉状,降低其粒径,形成微米尺度虾蟹壳微粒,提高比表面积。分别以酸和碱依次溶解虾蟹壳粉中的部分碳酸钙和蛋白质,虾蟹壳微粒表面将暴露出大量甲壳素。以碱液溶解蛋白质,也会引发甲壳素脱乙酰基,产生‑NH2等官能团。这样,微粒表面将生成大量含氨基的壳聚糖。氨基与脲醛树脂中的游离甲醛/羟甲基反应,既对树脂起增强作用,又降低了游离甲醛含量。

Abstract :
脲醛树脂(UF)在生产和使用过程中具有释放游离甲醛的缺点,以低摩尔比(F/U)生产UF是降低游离甲醛的有效手段,但会对其胶合强度产生负面影响。本研究采用聚二苯基甲烷二异氰酸酯(pMDI)改性低游离甲醛含量UF,再检测其相关性能。结果表明:随着pMDI用量的增加,UF黏度上升、固化时间下降、不溶物含量增加。当pMDI的添加量为9%时,胶合强度提升幅度最大,干状胶合强度为1.17 MPa,湿状胶合强度为1.15 MPa。当pMDI的添加量为5%时,湿状胶合强度为0.76 MPa,达到GB/T 9846—2015《普通胶合板》中室内Ⅱ类胶合板的要求。同时,固化的UF形成氨基甲酸酯结构,表现出更好的耐热性。

Abstract :
Composite materials, particularly wood-based panels, are frequently subjected to the harsh conditions of their service environments, leading to adhesive layer degradation and a consequent reduction in mechanical integrity and service life. The integration of self-repairing capabilities into these composites via microencapsulation presents a promising strategy to mitigate such degradation. Here, we developed a unique soy-protein-based adhesive with self-repairing capability by leveraging Pickering emulsion templated microcapsules. The microcapsules possess a melamine formaldehyde resin/polyurea shell and an isophorone diisocyanate (IPDI) core, which can exhibit excellent stability to maintain a 60.6 % encapsulation efficiency even after storing for 30 days. By incorporating with the microcapsules, the adhesive is demonstrated to display pressure-sensitive behavior. Such behavior enables the release of IPDI through mechanical stress and thus crosslinks with soy protein for crack repairing. The feature of wide particle size distribution of the microcapsules contributes to enhance both adhesion strength (reaching to 0.82 MPa to wood) and self-repairing rate (up to 93.5 %) of the wood-based composite. This innovative approach offers a practical and efficient method for endowing wood-based panels with autonomous healing capabilities, paving the way for the development of advanced self-repairing biomass composites. © 2025

Abstract :
Biomass-derived materials have garnered significant attention as sustainable anode candidates for lithium-ion batteries (LIBs) owing to their abundance, low cost, and environmental benefits. Among these, Cenchrus fungigraminus (JUJUNCAO) stands out due to its rapid growth, high yield, and exceptional environmental adaptability, making it a promising precursor for carbon-based electrodes. In this study, activated carbon was synthesized from JUJUNCAO through a two-step process involving carbonization and KOH activation. By systematically varying the activation temperature and the biochar/KOH weight ratio, we precisely controlled key properties such as the degree of graphitization, porosity, chemical composition, and electrochemical performance. The optimized activated carbon exhibited a high specific surface area of 1055 m2 g- 1 and delivered a reversible specific capacity of 393 mAh g- 1 after 650 charge/discharge cycles at a current density of 0.1 A g- 1. This superior electrochemical performance is attributed to the hierarchical porous structure and heteroatom doping, which synergistically enhance lithium-ion diffusion and electron transport. These findings not only underscore the potential of JUJUNCAO as a sustainable, high-performance anode material for LIBs but also pave the way for the high-value utilization of biomass in green energy storage technologies.
