As a class of functional crystalline porous materials, metal-organic frameworks(MOFs) gained rapid development in the past three decades and a large number of MOFs with ordered structures, high surface areas, and functionalized channels have been investigated. MOFs and MOF-derived/composite materials show great potential in many application fields. In this review, we discussed the main applications of MOFs and MOF-derived/composite materials in small molecule storage, separation, luminescence, sensing, multitype catalysis, and energy storage. In addition, challenges and problems in the future research of MOFsrelated fields are also discussed.

韧性作为一种新的灾害风险管理理念,已成为防灾减灾领域的研究热点,考虑到医疗系统在城市运行和灾后救援中的重要作用,在地震期间和之后,区域医疗系统应该具有足够的韧性,并提供连续的医疗服务。如何综合考虑区域范围内多家医院和交通系统的安全性、应急响应能力、多系统的整合与协作,有效评估区域医疗系统的抗震韧性水平,并提出科学的改进建议,对建设韧性城乡具有重要的理论意义。本文通过梳理国内外文献,阐明了区域医疗系统韧性的概念和内涵,总结了地震后短期应急和长期修复两个阶段韧性评估的重点,归纳了现有区域医疗系统韧性的评估框架,从医院集群系统、面向医疗的交通系统、应急医疗服务系统和医疗-交通耦合系统4个方面阐述了现有评估方法。区域医疗系统韧性的研究旨在提高其面对灾害时的抵抗性、短期适应性和长期恢复性,这些研究对于满足紧急和日常的医疗需求以及指导灾后恢复具有重要意义。目前区域医疗系统抗震韧性的研究取得了一些进展,但仍然存在一些挑战,本文最后展望了未来的研究方向。

本文依据三峡库区悬沙矿物组成和泥沙级配为依据配置沙样,选择长江上游典型微塑料PMMA和PS,在自制大型水箱中开展水流剪切作用下微塑料和泥沙异质聚集实验,分析微泥絮团的形态特征和聚集机制。结果表明在水流紊动剪切作用下,相比泥沙同质聚集的絮团粒径,微泥异质聚集的絮团粒径更大,且每毫升样品中微泥絮团上的微塑料吸附数量随水流剪切率增大而迅速增加。扫描电镜和能谱分析结果表明,在水动力条件下泥沙与PMMA、PS微球发生异质聚集,聚集过程中存在电子转移和化学态的转变,并产生不饱和键(C C)。由于PMMA官能团的结合能变化比PS大,此过程失电子更多、表面电荷更大,更容易与泥沙发生聚集。

通过金属辅助化学刻蚀法制备了硅纳米线(Si NWs),使用最小强化层脱层刻蚀技术分离了Ti_(3)C_(2)Tx纳米片,随后构筑了Ti_(3)C_(2)Tx/Si NWs异质结光电探测器。利用扫描电子显微镜对Ti_(3)C_(2)Tx/Si NWs的形貌进行分析,采用X射线衍射仪分析了Ti_(3)C_(2)Tx的结构。器件分析表明,该器件呈现出宽带响应特性,在920 nm处具有约526 mA/W的峰值响应度,其响应相较于平面硅器件有了很大的提升。这种光电特性与Si NWs中的光捕获效应有关。这些结果表明,Si NWs是未来高性能硅基光电探测器的潜在构建模块。

Ultrastructural pathological changes in the gut-associated lymphoid tissues of sacculus rotundus (SR) of rabbits infected with rabbit haemorrhagic disease virus (RHDV) were first observed. There were numerous holes at the luminal and basement membrane surfaces of the dome epithelium (DE), consistently accompanied by necrosis of lymphocytes and M-cells, and pronounced depletion of lymphocytes in the domes and follicles, decrease of DE complex with formation of pseudomembranous structure on the surface of the dome epithelium. A specific finding in lymphocytes and macrophages was that severe destruction detraction of the membrane of rough endoplasmic reticulum(RER) was accompanied by conspicious increase of solitary, ribo-some-like particles in the cytoplasm, with appearances of intranuclear particles and intranuclear inclusions. It was found that there were many round and dense virion-like particles, with 26 nm in diameter, in the nuclei and cytoplasm of lymphoctes, plasma cells, macrophages and fibroblasts, or in degenerated cells and cellular debris. At the same time, another round virion-like particles about 34 nm in diameter were also seen in the cytoplasm of some cells and interstitium. The results indicated that the appearances of the ribosome-like particles, virion-like particles and inclusion bodies were related to the replication and assembly of RHDV. The present observations suggested that DE of sacculus rotundus could be a open pathway and a transporting route for the entry of antigens into hosts. While the antigen is profoundly deleterious, DE may be as a closed portal or a barrier preventing the foreign antigenic materials from invading.
