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.

Furfural is one of the most important biomass-based platform molecules as sustainable precursors for chemicals and fuels. The electrochemical hydrodimerization of furfural can generate hydrofuroin, which is a promising precursor for gasoline or jet ***, steering the selectivity toward hydrodimerization under near-neutral conditions that suppress polymerization and disproportionation of furfural remains challenging. Herein, we discovered that tuning the electrolyte cations could be an effective and alternative strategy for modulating furfural reduction to the traditional electrocatalyst design. Under the optimal Ca2+cations,hydrofuroin yield could be much improved from other cations with hydrofuroin selectivity of 95.5%. The systematic characterization of the ion-centered double layer reflected the suitable sizes and charges of hydrated Ca2+for suppressing the hydrogen evolution reaction from activation of surrounding water molecules as well as encouraging furfural accumulation via non-covalent interaction for directing the electron transfer to furfurals. Ions with smaller or larger sizes can either activate local water molecules or form a crowded ionic interface that casts an adverse effect on furfural enrichment. This work not only presents an effective strategy for facilitating biomass valorization via hydrodimerization but also emphasizes the essential role of the ion-centered microenvironment for steering the electrocatalytic pathways.

“双碳”目标视域下,探究企业ESG(Environmental、Social and Governance)行为对碳排放的作用机理具有重要意义。考虑ESG行为存在表面上顺应迎合而实质上“言行不一”,构建了划分ESG行为类别的动态随机一般均衡(DSGE)模型,研究实质性ESG行为与策略性ESG行为对碳排放等宏观经济因素的动态传导机制。研究发现:相比难以实现碳减排的策略性ESG行为,企业采取实质性ESG行为能够显著降低碳排放量且对宏观经济有正向影响,推动经济向低碳绿色转型,实现减排与经济发展的“共赢”。企业实质性ESG行为对碳减排与经济增长的影响机制为:(1)内部资本投入机制:企业采取实质性ESG行为对碳减排技术研发投入形成溢出效应,且实质性ESG行为激励企业将生产要素投入由高碳产品转移到低碳产品,以实现“增低碳降高碳”,达到碳减排与经济增长的协调统一;(2)外部政策激励机制:企业采取实质性ESG行为可获得更多的政府碳减排补贴,促使企业增加低碳产出投入,实现外部政策激励与内部低碳转型的协同效应;(3)金融机构信贷优惠机制:企业采取实质性ESG行为能够激发金融机构对其实行差异化信贷优惠利率,增加企业碳减排技术的研发投入,推动绿色金融与绿色技术的协同发展。研究为辨识ESG行为类别推动企业低碳转型发展提供理论依据与政策启示。

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

暴雨和洪涝对滨海城市的地下空间构成严重威胁,应急疏散效率在受灾场景中至关重要。研究表明空间分区能有效提高疏散效率。目前传统分区方法依赖单一的最短路径方法,无法兼顾安全与高效。该文基于安全性评估提出了一种精细化分区方法。首先以应急疏散为目的,对地下空间按功能划分;其次考虑到灾害风险性、人员聚集性和设施高效性三个维度的影响因素,并构建安全性分区评价体系;最后综合上述因素,构建精细化分区划定体系。文章以深圳红树湾地铁站为案例,验证了新方法在保障疏散安全的同时,提升了疏散效率,为地下交通枢纽的防灾规划提供了理论支持。

As an effective, efficient, and economic approach for water purification, adsorbents and adsorption processes have been widely studied and applied in different aspects for a long time. In the recent years, a lot of novel adsorption processes have been developed for enhancing the efficiency of removing the organic and inorganic contaminants from water. This article reviews some new adsorbents and advanced adsorption methods that specialize in their compositions, structures, functions, and characteristics used in water treatment. The review emphasizes adsorption/catalytic oxidation process, adsorption/catalytic reduction process, adsorption coupled with redox process, biomimetic sorbent and its sorption behaviors of POPs, and modified adsorbents and their water purification efficiency.
