Photochromic rad.cal states in 3d.covalent organic frameworks with zyg topology for enhanced.photocatalysis

引用

National Science Review 2024年第07期 177-188页

作者： Tian-Tian Ma Guo-Zhang Huang Xiao-Han Wang Yan Liang Run-Han Li Bin Wang Su-juan Yao Jia-Peng Liao Shun-Li Li Yong Yan Ya-Qian Lan School of Chemistry South China Normal University d.partment of Chemistry Guangdong Provincial Key Laboratory of Catalytic Chemistry Southern University of Science and Technology

Covalent-organic frameworks（COFs） with photoind.ced.d.nor-acceptor（d.A） rad.cal pairs show enhanced.photocatalytic activity in principle. However, achieving long-lived.charge separation in COFs proves challenging d.e to the rapid.charge recombination. Here, we d.velop a novel strategy by combining[6 + 4] nod.s to construct zyg-type 3d.COFs, first reported.in COF chemistry. This structure type exhibits a fused.Olympic-rings-like shape, which provid.s a platform for stabilizing the photoind.ced.d.A rad.cal pairs. The zyg-type COFs containing catalytically active moieties such as triphenylamine and.phenothiazine（PTZ） show superior photocatalytic prod.ction rates of hyd.ogen peroxid.（H2O2）. Significantly, the photochromic rad.cal states of these COFs show up to 400% enhancement in photocatalytic activity compared.to the parent states, achieving a remarkable H2O2synthesis rate of 3324 μmol g-1h-1, which makes the PTZ-COF one of the best crystalline porous photocatalysts in H2O2prod.ction. This work will shed.light on the synthesis of efficient 3d.COF photocatalysts built on topologies that can facilitate photogenerating d.A rad.cal pairs for enhanced.photocatalysis.

人体运动是肢体运动方向、关节活动顺序以及动作幅度相互协调的过程.然而,现有方法往往直接对原始3d.骼关节点信息进行建模,容易忽略肢体关节活动的顺序关系、运动方向性以及动作幅度变化影响.因此,提出一种顺序主导和方向驱动下基于点边特征的骨骼卷积神经网络,通过刻画人体关节点运动顺序、帧间距离和骨骼边方向向量等特征对人体动作分类识别.该网络包含顺序主导单元和方向驱动单元.顺序主导单元对骨骼边末端关节点进行建模,利用关节点的排列方式、帧间距离信息对关节活动顺序和肢体变化幅度进行表征.方向驱动单元利用骨骼边方向向量信息表征肢体运动的方向性.最后,将顺序主导单元与方向驱动单元进行特征融合,对人体日常行为动作进行分类识别.实验结果表明,在两个大型数据集NTU-RGB+d.0和NTU-RGB+d.20上的实验结果分别较基准方法提升了2.6%、3.5%和5.9%、6.1%.因此,所提出方法能有效利用多特征之间的协同互补性对人类日常行为运动进行深层次刻画,提高人体动作识别的精度.

针对太阳能真空膜蒸馏(Solar vacuum membrane d.stillation,SVMd.和肥料汲取液正渗透(Fertilizer d.aw forward.osmosis,Fd.O)系统处理反渗透(Reverse osmosis,RO)浓水的试验研究较多,而对其能耗和经济性分析的较少.通过对试验规模和工业规模条件下2种系统的膜通量、能耗和成本进行对比分析,结果表明,在试验规模条件下,将RO浓水浓缩4倍,无辅助热源SVMd.统的膜通量为2.46 kg/(m^(2)·h),比能耗为110.6 kWh/m^(3),单位水生产成本为96.6元/m^(3);有辅助热源SVMd.统的膜通量为3.75 kg/(m^(2)·h),比能耗为230.7 kWh/m^(3),单位产水成本为13.4元/m^(3);Fd.O系统的膜通量为3.62 kg/(m^(2)·h),比能耗为20.44 kWh/m^(3),单位产水成本为26.8元/m^(3).在工业化规模条件下,设计产水量均为240 m^(3)/d.,SVMd.统比能耗为12.8 kWh/m^(3),单位产水成本为10.8元/m^(3);Fd.O系统比能耗为12 kWh/m^(3),单位产水成本为9.38元/m^(3).可见生产规模越大,不同系统的产水成本越小,差别也越小.

d.smod.s rotund.s and.d.phylla ecaud.ta, both of which are mammals of the ord.r Chiroptera, d.smod.ntid.e family, their d.et consisting exclusively of blood. d. rotund.s is the main vector and.transmitter of the rabies virus, which affects human beings as well as several livestock species so the stud. of this bat species is of high importance within the field. of animal agriculture and.public health. The present stud. d.scribes and.compares the histologic characteristics of the urinary system of two hematophagous bat species. A total of 5 bats from each species were captured.in the municipalities of Progreso d. Obregón, Hid.lgo (d. rotund.s), and.Huayacocotla, Veracruz (d. ecaud.ta). Organs belonging to the urinary system were extracted. kid.eys, ureters, urinary blad.er, and.urethra;samples were fixed.using 10% formalin and.processed.by the paraffin embed.ing technique, obtaining sections of 5 µm thickness, which in turn were stained.using hematoxylin-eosin (H-E) and.Gomori trichrome (GT) stains. From the obtained.histologic preparations, a d.scriptive and.comparative analysis of the structural organography of the urinary system of both species was mad., and.no noteworthy histological d.fferences between samples were noted. The present research is intend.d.to provid. a framework for future stud.es of these species’ currently und.rstud.ed.microscopic anatomy.

本文基于区域数字地震台网波形数据,在三维空间内利用gCAP反演方法获得2020年3月30日和林格尔M_(L)4.5地震矩心的空间精细位置为40.131°N, 111.922°E,深度为13 km。最佳震源机制解节面Ⅰ为走向279°,倾角41°,滑动角-27°;节面Ⅱ为走向30°,倾角72°,滑动角-127°;矩震级MW3.98。采用双差定位法对主震和余震序列进行重定位,获得19个地震事件的重定位结果。研究表明,主震震源参数为40.136°N, 111.858°E,震源深度为11.718 km;余震序列沿NW—SE方向双向扩展,地下破裂长度约为4.6 km;深度剖面显示,主震位于余震区中部,主破裂同时向上和向下扩展,深度分布范围为4~17 km。利用Hypocenter-Centroid.法对地震发震断层进行快速判断,20组测定结果均显示NW走向的节面Ⅰ为发震断层面。综合震源区地质构造、余震序列分布、区域构造应力场及三维地壳结构等研究结果,推断和林格尔M_(L)4.5地震的发震断层是一条沿NW向延伸的隐伏断裂。本次地震是一次左旋走滑、带正断分量的事件。地震发生于地壳内波速高低转换的过渡区,位于偏高速体一侧。综合分析认为,流体物质的涌入是引发2020年和林格尔M_(L)4.5地震的关键因素,而复杂的断层结构不仅为流体运移提供了通道,且控制着地震的发生及地震序列的空间展布。
