2Laser performance upgrade for precise ICF experiment in SG-Ⅲ laser facility显示文摘The SG-Ⅲlaser facility(SG-Ⅲ)is the largest laser driver for inertial confinement fusion(ICF)researches in China,which has 48 beamlines and can deliver 180 kJ ultraviolet laser energy in 3 ns.In order to meet the requirements of precise physics experiments,some new functionalities need to be added to SG-Ⅲand some intrinsic laser performances need upgrade.So at the end of SG-Ⅲ's engineering construction,the 2-year laser performance upgrade project started.This paper will introduce the newly added functionalities and the latest laser performance of SG-Ⅲ.With these function extensions and performance upgrade,SG-Ⅲis now fully prepared for precise ICF experiments and solidly paves the way towards fusion ignition.Wanguo Zheng Xiaofeng Wei Qihua Zhu Feng Jing Dongxia Hu Xiaodong Yuan Wanjun Dai Wei Zhou Fang Wang Dangpeng Xu Xudong Xie Bin Feng Zhitao Peng Liangfu Guo Yuanbin Chen Xiongjun Zhang Lanqin Liu Donghui Lin Zhao Dang Yong Xiang Rui Zhang Fang Wang Huaiting Jia Xuewei Deng 2017Matter and Radiation at Extremes2017,2,5:13
3The fractal characteristic change in the Huanghe River Estuary due to the hydrodynamic conditions’variation显示文摘The study area lies in the subaqueous delta, which came into being in 1964~1976. One oil-field road has been built for exploring petroleum to form a wave barrier. The hydrodynamic conditions on the north side of the road are relatively violent, on the contrary the hydrodynamic conditions on the south side of the road are nearly placid. This makes the study area a natural laboratory for studying the influence of the hydrodynamic conditions on the fractal characteristics of the tidal flat. Selecting an area is named Case Ⅰ on the side of stronger hydrodynamic activities and an area is named Case Ⅱ on the other side. Measuring the topography and sampling and analyzing the granulometrical composition, it is found that the hydrodynamic conditions have fatal influence on the surface fractal dimensions and the granulometrical fractal dimensions of the area. In Case Ⅰ, which has strong hydrodynamic conditions, the surface fractal dimensions are obviously larger than those of Case Ⅱ, and the granulometrical fractal dimensions are relatively smaller than those of Case Ⅱ, the surface fractal dimensions of Case Ⅰ decrease quickly with the increase of grid size; the granulometrical fractal dimensions are disperse, while the hydrodynamic conditions of Case Ⅱ are just reverse. A sampling line and a core sampling on each side of the road are selected. It is found that on the south side of the road the granulometrical fractal dimensions vary regularly in the line and with the depth, the farther apart from the road, the smaller the fractal dimensions, and the deeper the sampling position the larger the fractal dimensions, while granulometrical fractal dimensions on the north side of the road have no such regularity pattern. The mechanism of the influence of the hydrodynamic conditions on the fractal characteristics is discussed.Jia Yonggang, Fu Yuanbin, Xu Guohui, Shan Hongxian, Cao Xueqing Environmental Engineering Department, Ocean University of China, Qingdao 266003,China 2003Acta Oceanologica Sinica2003,22,2:13
4Spatial and temporal variations of C_3/C_4 relative abundance in global terrestrial ecosystem since the Last Glacial and its possible driving mechanisms显示文摘The primary factor controlling C 3 /C 4 relative abundance in terrestrial ecosystem since the Last Glacial has been widely debated. Now more and more researchers recognize that climate, rather than atmospheric CO 2 concentration, is the dominant factor. However, for a specific area, conflicting viewpoints regarding the more influential one between temperature and precipitation still exist. As temperature and precipitation in a specific area usually not only vary within limited ranges, but also covary with each other, it is difficult to get a clear understanding of the mechanism driving C 3 /C4 relative abundance. Therefore, systematic analysis on greater spatial scales may promote our understanding of the driving force. In this paper, records of C3/C4 relative abundance since the Last Glacial on a global scale have been reviewed, and we conclude that: except the Mediterranean climate zone, C3 plants predominated the high latitudes during both the Last Glacial and the Holocene; from the Last Glacial to the Holocene, C4 relative abundances increased in the middle latitudes, but decreased in the low latitudes. Combining with studies of modern process, we propose a simplified model to explain the variations of C3 /C4 relative abundance in global ecosystem since the Last Glacial. On the background of atmospheric CO2 concentration since the Last Glacial, temperature is the primary factor controlling C3/C4 relative abundance; when temperature is high enough, precipitation then exerts more influence. In detail, in low latitudes, temperature was high enough for the growth of C4 plants during both the Last Glacial and the Holocene; but increased precipitation in the Holocene inhibited the growth of C4 plants. In middle latitudes, rising temperature in the Holocene promoted the C4 expansion. In high latitudes, temperature was too low to favor the growth of C4 plants and the biomass was predominated by C3 plants since the Last Glacial. Our review would benefit interpretation of newly gained records of C3/C4 relative abundance from different areas and different periods, and has its significance in the understanding of the driving mechanisms of C3/C4 variations on longer timescales (e.g., since the late Miocene) with reliable records of temperature and atmospheric CO2 concentration.RAO ZhiGuo CHEN FaHu ZHANG Xiao XU YuanBin XUE Qian ZHANG PingYu 2012Chinese Science Bulletin2012,57,31:6
5Self-crosslinkable chitosan-hyaluronic acid dialdehyde nanoparticles for CD44-targeted siRNA delivery to treat bladder cancer显示文摘Bladder cancer is one of the concerning malignancies worldwide,which is lacking effective targeted therapy.Gene therapy is a potential approach for bladder cancer treatment.While,a safe and effective targeted gene delivery system is urgently needed for prompting the bladder cancer treatment in vivo.In this study,we confirmed that the bladder cancer had CD44 overexpression and small interfering RNAs(siRNA)with high interfere to Bcl2 oncogene were designed and screened.Then hyaluronic acid dialdehyde(HAD)was prepared in an ethanol-water mixture and covalently conjugated to the chitosan nanoparticles(CS-HAD NPs)to achieve CD44 targeted siRNA delivery.The in vitro and in vivo evaluations indicated that the siRNA-loaded CS-HAD NPs(siRNA@CS-HAD NPs)were approximately 100 nm in size,with improved stability,high siRNA encapsulation efficiency and low cytotoxicity.CS-HAD NPs could target to CD44 receptor and deliver the therapeutic siRNA into T24 bladder cancer cells through a ligand-receptor-mediated targeting mechanism and had a specific accumulation capacity in vivo to interfere the targeted oncogene Bcl2 in bladder cancer.Overall,a CD44 targeted gene delivery system based on natural macromolecules was developed for effective bladder cancer treatment,which could be more conducive to clinical application due to its simple preparation and high biological safety.Ye Liang Yonghua Wang Liping Wang Zhijuan Liang Dan Li Xiaoyu Xu Yuanbin Chen Xuecheng Yang Hongbo Zhang Haitao Niu 2021Bioactive Materials2021,6,2:5

7Construction of 2D/2D Z-scheme MnO_(2-x)/g-C_(3)N_(4) photocatalyst for efficient nitrogen fixation to ammonia显示文摘Reducing nitrogen to ammonia with solar energy has become a wide concern when it comes to photocatalysis research.It is considered to be one of the more promising alternate options for the conventional Haber-Bosch cycle.Herein,2D g-C_(3)N_(4)composites with modifying ultrathin sheet MnO_(2-x)were prepared and used as nitrogen fixation photocatalyst.With the assistance of the nature of MnO_(2-x),the generation rate of NH_(3)reached 225 mmol g^(-1)h^(-1),which is more than twice over the rate of pristine 2D g-C_(3)N_(4)(107 mmol g^(-1)h^(-1)).The presence of ultrathin sheet MnO_(2-x)shortens the gap of the carriers to the surface of photocatalyst.Thus the speed of electron transfer gets increased.Besides,the construction of Z-scheme heterojunction boosts the separation and migration of photogenerated carriers.As a result,the nitrogen reduction reaction(NRR)performance gets enhanced.The work may provide an example of promoting the NRR performance of non-metallic compound.Limin Yu Zhao Mo Xianglin Zhu Jiujun Deng Fan Xu Yanhua Song Yuanbin She Huaming Li Hui Xu 2021Green Energy & Environment2021,6,4:3
8Deep multimodal learning for municipal solid waste sorting显示文摘Automated waste sorting can dramatically increase waste sorting efficiency and reduce its regulation cost. Most of the current methods only use a single modality such as image data or acoustic data for waste classification, which makes it difficult to classify mixed and confusable wastes. In these complex situations, using multiple modalities becomes necessary to achieve a high classification accuracy. Traditionally, the fusion of multiple modalities has been limited by fixed handcrafted features. In this study, the deep-learning approach was applied to the multimodal fusion at the feature level for municipal solid-waste sorting.More specifically, the pre-trained VGG16 and one-dimensional convolutional neural networks(1 D CNNs) were utilized to extract features from visual data and acoustic data, respectively. These deeply learned features were then fused in the fully connected layers for classification. The results of comparative experiments proved that the proposed method was superior to the single-modality methods. Additionally, the feature-based fusion strategy performed better than the decision-based strategy with deeply learned features.LU Gang WANG YuanBin XU HuXiu YANG HuaYong ZOU Jun 2022Science China(Technological Sciences)2022,65,2:2
9Chinese Automobile Industry’s Position in the Global Value Chain and Its Development Paths Under New Circumstances显示文摘While analyzing how the global automobile landscape has shifted and what role the Chinese automobile industry is playing in the global value chain,this paper points out that traditional automobile superpowers are being overtaken by emerging markets and countries;though China’s position in the global automobile industry keeps rising,it is yet to be intimately involved and incorporated into each link of the global value chain.China is now somehow stuck in the middle reaches of the global value chain and is susceptible to being replaced by other countries and regions in the global automobile trade.Under new circumstances,the Chinese automobile industry must step up its transformation from depending on scale and speed to seeking quality and profitability.Not only must China consistently and steadily promote openness within its automobile industry and steadfastly hold on to trade liberalization and economic globalization,but also must deepen its reform to improve the internal institutional environment for the development of its automobile industry.Wang Yuanbin Wang Chunyu Zheng Xuedang Xu Qingtong 2020Contemporary Social Sciences2020,5,3:0
10Selective aerobic oxidation of p-cresol with co-catalysts between metalloporphyrins and metal salts显示文摘A green and efficient method for the selective aerobic oxidation of p-cresol to p-hydroxybenzaldehyde catalyzed by co-catalysts between metalloporphyrins and metal salts was investigated and developed. The relationship between the synergistic catalytic effects and the composition as well as amount of co-catalysts was investigated. Moreover, the influence of different reaction conditions was studied in details. A high p-cresol conversion(N 99%) and p-hydroxybenzaldehyde selectivity(83%) were obtained using only 1.125 × 10^(-5) mol T(p-CH_3 O)PPFe^(III)Cl-Co(OAc)_2 used under mild, optimized reaction conditions. A possible mechanism for the reaction was also proposed. This work would be meaningful and instructive for the further researches and applications of co-catalyst system on oxidation of cresols and could give some enlightenment on the selectively catalytic oxidation of the side-chain alkyls of aromatics.Yuanbin She Yao Fan Lei Zhang Ying Xu Min Yu Haiyan Fu 2018Chinese Journal of Chemical Engineering2018,26,7:0
11A Review of Solid Electrolyte Interphase(SEI)and Dendrite Formation in Lithium Batteries显示文摘Lithium-metal batteries with high energy/power densities have significant applications in electronics,electric vehicles,and stationary power plants.However,the unstable lithium-metal-anode/electrolyte interface has induced insufficient cycle life and safety issues.To improve the cycle life and safety,understanding the formation of the solid electrolyte interphase(SEI)and growth of lithium dendrites near the anode/electrolyte interface,regulating the electrodeposition/electrostripping processes of Li^(+),and developing multiple approaches for protecting the lithium-metal surface and SEI layer are crucial and necessary.This paper comprehensively reviews the research progress in SEI and lithium dendrite growth in terms of their classical electrochemical lithium plating/stripping processes,interface interaction/nucleation processes,anode geometric evolution,fundamental electrolyte reduction mechanisms,and effects on battery performance.Some important aspects,such as charge transfer,the local current distribution,solvation,desolvation,ion diffusion through the interface,inhibition of dendrites by the SEI,additives,models for dendrite formation,heterogeneous nucleation,asymmetric processes during stripping/plating,the host matrix,and in situ nucleation characterization,are also analyzed based on experimental observations and theoretical calculations.Several technical challenges in improving SEI properties and reducing lithium dendrite growth are analyzed.Furthermore,possible future research directions for overcoming the challenges are also proposed to facilitate further research and development toward practical applications.Borong Li Yu Chao Mengchao Li Yuanbin Xiao Rui Li Kang Yang Xiancai Cui Gui Xu Lingyun Li Chengkai Yang Yan Yu David P.Wilkinson Jiujun Zhang 2023Electrochemical Energy Reviews2023,6,1:0
12Efficient capture of C_(2)H_(2)from CO_(2)and C_(n)H_(4)by a novel fluorinated anion pillared MOF with flexible molecular sieving effect显示文摘The efficient separation of acetylene(C_(2)H_(2))from carbon dioxide(CO_(2))and CnH_(4)(n=1 and 2)to manufacture high purity C_(2)H_(2)and recover other light hydrocarbons is technologically important,while posing significant challenges.Herein,we reported a new TiF62−anion(TIFSIX)pillared metal-organic framework(MOF)ZNU-5(ZNU=Zhejiang Normal University)with ultramicropores for highly selective C_(2)H_(2)capture with low adsorption heat through gate opening based molecular sieving effect.ZNU-5 takes up a large amount of C_(2)H_(2)(128.6 cm^(3)/g)at 1.0 bar and 298 K but excludes CO_(2),CH_(4),and C_(2)H_(4).Such high capacity has never been realized in MOFs with molecular sieving.The breakthrough experiments further confirmed the highly selective C_(2)H_(2)separation performance from multi-component gas mixtures.3.3,2.8,and 2.2 mmol/g of C_(2)H_(2)is captured at ZNU-5 from equimolar C_(2)H_(2)/CO_(2),C_(2)H_(2)/CO_(2)/CH_(4),and C_(2)H_(2)/CO_(2)/CH_(4)/C_(2)H_(4)mixtures,respectively.Furthermore,2.6,2.0,and 1.5 mmol/g of>98%purity C_(2)H_(2)can be recycled from the desorption process.Combining high working capacity,low adsorption heat,as well as good recyclability,ZNU-5 is promising for C_(2)H_(2)purification.Lingyao Wang Nuo Xu Yongqi Hu Wanqi Sun Rajamani Krishna Jiahao Li Yunjia Jiang Simon Duttwyler Yuanbin Zhang 2023Nano Research2023,16,2:0
13Studies on QSAR of metalloporphyrin catalysts in the oxidation of cyclohexane to adipic acid显示文摘The catalysis of chloridized metalloporphyrins in the oxidation of cyclohexane to adipic acid was systemati-cally investigated.The turnover numbers(TON)data of 19 catalysts were obtained experimentally under optimal reac-tion conditions,and 2.4x106 TON for T(o-Cl)PP-MnIIICl catalyst at 2.0x10–6 mol/L of dosage was reached under the conditions of dioxygen pressure of 2.5 MPa at 150°C for 4 h.This was the best result reported for this reaction up to now.The QSAR models for each concerned metallopor-phyrin were established,where the catalytic activity was significantly correlated with the ELUMO(the energy level of the lowest unoccupied molecule orbit)and LM-N(the bond length between metal-nitrogen atoms).Using the QSAR models,four new metalloporphyrins with substituted nitro group were designed,and their catalytic activities were predicted.The experimental TON data of newly designed porphyrins were in good agreement with the predicted ones,and the square of their correlation coefficient was more than 0.958.The above results demonstrated that the proposed structure-activity relationship model could be applied to design some new metalloporphyrin catalysts,and to predict their catalytic activity in cyclohexane oxidation.CHEN Yixia SHE Yuanbin XU Jing LI Yan 2007Frontiers of Chemical Science and Engineering2007,1,2:0
14Cryo-induced closely bonded heterostructure for effective CO2 conversion:The case of ultrathin BP nanosheets/g-C3N4显示文摘Black phosphorus(BP),an interesting and multi-functional non-metal material,has attracted widespread attention.In this work,2D BP/2D g-C3N4 heterostructure had been fabricated at extremely low temperature,which was used to reduce CO2 for the first time.With introduction of 2D BP,the separation of photogenerated holes and electrons was extremely boosted,and composites showed excellent photocatalytic performance(CO2 to CO).Meanwhile,the targeted composite could keep high selectivity for CO generation and CO generation rate can be up to 187.7μmol g−1 h^−1.The formation process of the unique heterostructure and the key factor affecting the photocatalytic performance were also discussed.This work provides a new approach for designing metal free photocatalyst,which is used for CO2 reduction.Guli Zhou Jinman Yang Xingwang Zhu Qidi Li Qing Yu Wiam El-alami Chongtai Wang Yuanbin She Junchao Qian Hui Xu Huaming Li 2020Journal of Energy Chemistry2020,29,10:0
