The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

合理调度有限的码头资源以满足船舶的装卸时间要求是自动化集装箱码头的重要目标之一。针对自动化集装箱码头自动导引车(automated guided vehicle,AGV)配置与调度问题,考虑船舶装卸时间要求和AGV运输过程中的路径冲突,提出分阶段调度策略。将船舶装卸作业分为卸船阶段、装卸同步阶段、装船阶段三个阶段,在每个阶段中,建立以最小化最大完工时间和最小化AGV空载和等待时间为双目标的调度优化模型,并设计基于NSGA-Ⅱ的启发式算法求解。根据本阶段的实际完工时间,从最优解集中选择下一阶段AGV的配置与调度方案。最后对比其他调度方案表明本文调度方案能够满足集装箱船的装卸时间要求,且提高了AGV的利用率,更符合码头实际作业要求。

以水热稳定性高的Al-SBA-15介孔分子筛为载体,负载CuO制备了CuO/Al-SBA-15催化剂,并采用一步合成法制备出Fe-Al-SBA-15催化剂,对其进行了XRD、TEM及FTIR测试及表征。分别以Al-SBA-15、CuO/Al-SBA-15及Fe-Al-SBA-15为催化剂,进行了棕榈酸甲酯的非加氢脱氧反应。结果表明：CuO在介孔材料表面均匀分散,3种催化剂中CuO/Al-SBA-15的脱氧效果最好,确定最佳反应条件为反应温度342℃,反应时间2 h。与未加催化剂相比,在最佳反应条件下,棕榈酸甲酯脱羧产生烃类的选择性提高了40%-60%。催化剂重复使用3次,棕榈酸甲酯的转化率无明显下降。根据活性评价推测脱羧反应机理为：在亚临界水中棕榈酸甲酯水解生成棕榈酸,在催化剂的活性中心上羧酸根负离子形成羧基化物,之后被活化氢进攻邻近羧基的C—C键,进而CO2脱附下来,生成主产物十五烷。
