| 1 | Frontiers in circularly polarized luminescence:molecular design,self-assembly,nanomaterials,and applications显示文摘The research in circularly polarized luminescence has attracted wide interest in recent years.Efforts on one side are directed toward the development of chiral materials with both high luminescence efficiency and dissymmetry factors,and on the other side,are focused on the exploitations of these materials in optoelectronic applications.This review summarizes the recent frontiers(mostly within five years)in the research in circularly polarized luminescence,including the development of chiral emissive materials based on organic small molecules,compounds with aggregation-induced emissions,supramolecular assemblies,liquid crystals and liquids,polymers,metal-ligand coordination complexes and assemblies,metal clusters,inorganic nanomaterials,and photon upconversion systems.In addition,recent applications of related materials in organic light-emitting devices,circularly polarized light detectors,and organic lasers and displays are also discussed. | Zhong-Liang Gong Xuefeng Zhu Zhonghao Zhou Si-Wei Zhang Dong Yang Biao Zhao Yi-Pin Zhang Jianping Deng Yixiang Cheng You-Xuan Zheng Shuang-Quan Zang Hua Kuang Pengfei Duan Mingjian Yuan Chuan-Feng Chen Yong Sheng Zhao Yu-Wu Zhong Ben Zhong Tang Minghua Liu | 2021 | Science China Chemistry2021，64，12： | 3 |
| 2 | Tectonic affinity of Paleozoic stratigraphic slices along the northern margin in Dabie Orogen,central China: evidence from Pb isotope of rocks显示文摘Metavolcanic and metasedimentary rocks from the Paleozoic tectono-stratigraphic units along the northern margin in the Dabie orogen show that there are two types of Pb isotopic compositions, which have some affined regularity with tectonic subdivision. Compared with the main tectonic units of the Qinling orogen, the Dingyuan Formation should be the part of the South Qinling orogenic belt or the northern margin of the Yangtze craton, characterized by less radiogenic Pb isotopic composition, and the Guishan Formation, Nanwan Formation-Foziling Group and the Carboniferous should be the part of the North Qinling orogenic belt which is extended to the east, characterized by more radiogenic Pb isotopic composition. These facts combined with the distribution of the geological units suggest that the Paleozoic subduction zone between the Yangtze and North China cratons should be located in the north boundary of the Nanwan Formation-Foziling Group or somewhere that is covered by the Nanwan Formation-Foziling Group now. From the Pb isotopic evidence and suggestion presented here, one aspect of the constraint is provided for determining the position of the Triassic collision suture between the two cratons. | XU Qidong, OUYANG Jianping, ZHANG Benren and KUANG Shaoping(1.

| 3 | Effect of Al_(2)O_(3)/CaO on the melting and mineral transformation of Ningdong coal ash显示文摘Coal ash melting characteristics has a direct impact on the smooth operation of entrained gasifier.Mineral conversion of coal ash is very significant to be investigated,because the mineral can affect the melting temperature and viscosity under high temperature conditions.In this paper,the effects of different Al2O3/CaO on the mineral conversion,melting temperature and viscosity of Ningdong coal ash are studied by the combination of experiment and simulation.The trend of melting temperature decreases firstly and rises with increasing Al_(2)O_(3)/CaO.The ashmelting point reached to the lowestwhen the ratio is 1.23.XRD and Factsage software are used to analyze crystallization behavior of samples.The results showthat the content of anorthite,albite and corundumincreases and subsequently decreases,while the content of mullite decreases firstly and then rises with increasing Al_(2)O_(3)/CaO.High content with CaO can contribute to form albite and anorthite of low-melting.Besides,high content with Al_(2)O_(3) can tend to produce mullite of high-melting.The results of experimental and simulation are basically the same,which lays a foundation for the melting characteristics of Ningdong coal ash and can provide technical support for the smooth operation of the entrained-gasifier. | Feng Wang Min Yao Haoyong Kan Jianping Kuang Ping Li Jiashuo Zhang Yixin Zhang | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 3 |

| 6 | Effects of different aggregation forms of LHC Ⅱ from Bryopsis corticulans on the excited state properties of Chl a显示文摘Steady-state and time-resolved fluo- rescence spectroscopies have been used to study the excited state properties of Chl a in different ag- gregation forms of light-harvesting complex II (LHC II) from an intertidal green alga, Bryopsis corticulans, i.e. LHC II monomer, trimer and oligomer. When either Chl a or Chl b was selectively excited, the observed decrease in Chl a fluorescence in the oligomer is proved to be caused mainly by the fast fluorescence quenching among Chl a molecules, rather than by the decrease in Chl b-to-Chl a singlet excitation transfer efficiency. Analyses of the picosecond time-resolved fluorescence kinetics identified two exponential de- cay components in all of the three forms of LHC II: a longer-lived component (4.1―4.7 ns) originating from fluorescence emission of Chl a, and a shorter-lived one (135―540 ps) from the rapid equilibration of singlet excitation among Chl a molecules. The time constant of excitation equilibration is 135 ps in oli- gomer, 520 ps in trimer and 540 ps in monomer. These results imply that LHC II in oligomer form is inherently able to quench Chl a excitation, a mecha- nism which may be related to the photoprotection of PS II via changing the degree of LHC II aggregation in Bryopsis corticulans. | ZUO Ping CHEN Hui WU Yishi SHEN Shihua WANG Peng AI Xicheng ZHANG Jianping LI Liangbi KUANG Tingyun | 2006 | Chinese Science Bulletin2006，51，12： | 0 |
| 7 | Atomic Cu Sites Engineering Enables Efficient CO_(2)Electroreduction to Methane with High CH_(4)/C_(2)H_(4)Ratio显示文摘Electrochemical reduction of CO_(2)into high-value hydrocarbons and alcohols by using Cu-based catalysts is a promising and attractive technology for CO_(2)capture and utilization,resulting from their high catalytic activity and selectivity.The mobility and accessibility of active sites in Cubased catalysts significantly hinder the development of efficient Cu-based catalysts for CO_(2)electrochemical reduction reaction(CO_(2)RR).Herein,a facile and effective strategy is developed to engineer accessible and structural stable Cu sites by incorporating single atomic Cu into the nitrogen cavities of the host graphitic carbon nitride(g-C_(3)N_(4))as the active sites for CO_(2)-to-CH_(4)conversion in CO_(2)RR.By regulating the coordination and density of Cu sites in g-C_(3)N_(4),an optimal catalyst corresponding to a one Cu atom in one nitrogen cavity reaches the highest CH_(4)Faraday efficiency of 49.04%and produces the products with a high CH_(4)/C_(2)H_(4)ratio over 9.This work provides the first experimental study on g-C_(3)N_(4)-supported single Cu atom catalyst for efficient CH_(4)production from CO_(2)RR and suggests a principle in designing highly stable and selective high-efficiency Cu-based catalysts for CO_(2)RR by engineering Cu active sites in 2D materials with porous crystal structures. | Minhan Li Fangzhou Zhang Min Kuang Yuanyuan Ma Ting Liao Ziqi Sun Wei Luo Wan Jiang Jianping Yang | 2023 | Nano-Micro Letters2023，15，12： | 0 |
| 8 | Tandem engineering for CO_(2)electrolysis toward multicarbon products显示文摘Electrocatalysis of CO_(2)toward multicarbon(C_(2+))products have multifaceted applications in the energy and chemical industries,offers an attractive route to mitigate carbon emissions and abate the depletion of fossil fuels.However,the productivity of CO_(2)-to-C_(2+)products suffers from a low selectivity and reaction rate owing to the difficulty in C-C coupling and the multiple electronproton transfer steps.Recently,numerous tandem catalysts have been developed to improve the selectivity and formation rate of CO_(2)-to-C_(2+)products via coupled multiple reaction steps,exhibiting high industrial practicability.This review summarized recent progresses in the formation of C_(2+)products from CO_(2)electrolysis on tandem catalysts.In this review,we highlight the cooperative regulation strategy of tandem catalysts formed by introducing different types of new components and reveal the relationships between*CO intermediate mass transport and the selectivity of C_(2+)products.Moreover,theoretical insight into the tandem catalytic mechanisms underlying the enhanced C_(2+)selectivity is also provided.Finally,the remaining challenges and opportunities for the electrocatalytic CO_(2)toward C_(2+)products are discussed. | Tinghui Yang Min Kuang Jianping Yang | 2023 | Nano Research2023，16，7： | 0 |
