地震等灾害的突发性和破坏性导致大量且多样的避难需求,但灾后物资往往不能快速有效地送达,容易出现应急资源供需匹配低效的问题。综合考虑分层避难需求下应急避难场所选址、人员疏散和物资分配等三个重要决策,基于灾后三层应急避难结构框架,本文构建了具有递归机制的应急避难网络,包括避难灾民和不同种类物资需求数量预测、应急避难场所选址和人员疏散以及物资分配;还提出了混合决策方法,包括模糊聚类和多目标规划模型,旨在优化应急避难场所位置和开放数量、灾民疏散距离以及物资满足率。以四川省成都市为例,本文分析了灾民疏散和安置过程,结果表明本文所提方法能公平快速地解决灾后初期应急避难场所选址、灾民疏散和物资分配问题,确保应急避难行动有序高效地进行。

Status and prospects for symmetric organic redox flow batteries

引用

Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.Adam Dyker Department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.
