| 3 | Laser 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 | 2017 | Matter and Radiation at Extremes2017，2，5： | 13 |
| 4 | Carbon dioxide capture using polyethylenimine-loaded mesoporous carbons显示文摘A high efficiency sorbent for CO2 capture was developed by loading polyethylenimine (PEI) on mesoporous carbons which possessed well-developed mesoporous structures and large pore volume. The physicochemical properties of the sorbent were characterized by N2 adsorption/desorption, scanning electron microscopy (SEM), thermal gravimetric analysis (TG) and Fourier transform infrared spectroscopy (FT-IR) techniques followed by testing for CO2 capture. Factors that affected the sorption capacity of the sorbent were studied. The sorbent exhibited extraordinary capture capacity with CO2 concentration ranging from 5% to 80%. The optimal PEI loading was determined to be 65 wt.% with a CO2 sorption capacity of 4.82 mmol-CO2 /g-sorbent in 15% CO2 /N2 at 75°C, owing to low mass-transfer resistance and a high utilization ratio of the amine compound (63%). Moisture had a promoting effect on the sorption separation of CO2 . In addition, the developed sorbent could be regenerated easily at 100°C, and it exhibited excellent regenerability and stability. These results indicate that this PEI-loaded mesoporous carbon sorbent should have a good potential for CO2 capture in the future. | Jitong Wang Huichao Chen Huanhuan Zhou Xiaojun Liu Wenming Qiao Donghui Long Licheng Ling | 2013 | Journal of Environmental Sciences2013，25，1： | 9 |
| 5 | Electrical transport properties of Fe Se single crystal under high magnetic field显示文摘Understanding the normal electronic state is crucial for unveiling the mechanism of unconventional superconductivity(SC). In this paper, by applying a magnetic field of up to 37T on FeSe single crystals, we could reveal the normal-state transport properties after SC was completely suppressed. The normal-state resistivity exhibited a Fermi liquid behavior at low temperatures. Large orbital magnetoresistance(MR) was observed in the nematic state with H//c, whereas MR was negligible with H//ab. The magnitude of the orbital MR showed an unusual reduction, and Kohler’s rule was severely violated below 10-25 K;these were attributable to spin fluctuations. The results indicated that spin fluctuations played a paramount role in the normalstate transport properties of FeSe albeit the Fermi liquid nature was at low temperature. | HongHui Wang ZhaoHui Cheng MengZhu Shi DongHui Ma WeiZhuang Zhuo ChuanYing Xi Tao Wu JianJun Ying XianHui Chen | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 6 |
| 6 | Enhanced Reconfigurable Intelligent Surface Assisted mmWave Communication: A Federated Learning显示文摘Reconfigurable intelligent surface(RIS)has been proposed as a potential solution to improve the coverage and spectrum efficiency for future wireless communication.However,the privacy of users’data is often ignored in previous works,such as the user’s location information during channel estimation.In this paper,we propose a privacy-preserving design paradigm combining federated learning(FL)with RIS in the mmWave communication system.Based on FL,the local models are trained and encrypted using the private data managed on each local device.Following this,a global model is generated by aggregating them at the central server.The optimal model is trained for establishing the mapping function between channel state information(CSI)and RIS’configuration matrix in order to maximize the achievable rate of the received signal.Simulation results demonstrate that the proposed scheme can effectively approach to the theoretical value generated by centralized machine learning(ML),while protecting user’privacy. | Lixin Li Donghui Ma Huan Ren Dawei Wang Xiao Tang Wei Liang Tong Bai | 2020 | China Communications2020，17，10： | 6 |

| 8 | Dynamic prediction of building subsidence deformation with data-based mechanistic self-memory model显示文摘This paper describes a building subsidence deformation prediction model with the self-memorization principle.According to the non-linear specificity and monotonic growth characteristics of the time series of building subsidence deformation,a data-based mechanistic self-memory model considering randomness and dynamic features of building subsidence deformation is established based on the dynamic data retrieved method and the self-memorization equation.This model first deduces the differential equation of the building subsidence deformation system using the dynamic retrieved method,which treats the monitored time series data as particular solutions of the nonlinear dynamic system.Then,the differential equation is evolved into a difference-integral equation by the self-memory function to establish the self-memory model of dynamic system for predicting nonlinear building subsidence deformation.As the memory coefficients of the proposed model are calculated with historical data,which contain useful information for the prediction and overcome the shortcomings of the average prediction,the model can predict extreme values of a system and provide higher fitting precision and prediction accuracy than deterministic or random statistical prediction methods.The model was applied to subsidence deformation prediction of a building in Xi'an.It was shown that the model is valid and feasible in predicting building subsidence deformation with good accuracy. | WANG Wei SU JingYu HOU BenWei TIAN Jie MA DongHui | 2012 | Chinese Science Bulletin2012，57，26： | 5 |

| 10 | The Glacier Area Changes in the Qangtang Plateau Based on the Multi-temporal Grid Method and its Sensitivity to Climate Change显示文摘Glacier area changes in the Qangtang Plateau are analyzed during 1970-2000 using air photos,relevant photogrammetric maps and satellite images based on the multi-temporal grid method.The results indicate that the melting of glaciers accelerated,only a few of glaciers in an advancing state during 1970-2000 in the whole Qangtang Plateau.However,the glaciers seemed still more stable in the study area than in most areas of western China.We estimate that glacier retreat was likely due to air temperature warming during 1970-2000 in the Qangtang Plateau.Furthermore,the functional model of glacier system is applied to study climate sensitivity of glacier area changes,which indicates that glacier lifespan mainly depends on the heating rate,secondly the precipitation,and precipitation increasing can slow down glacier retreat and make glacier lifespan prolonged. | WANG Liping XIE Zichu WANG Xin LIU Shiyin DING Liangfu SHANGGUAN Donghui | 2011 | Journal of Mountain Science2011，8，6： | 5 |
| 11 | Chemical formation and source apportionment of PM_(2.5) at an urban site at the southern foot of the Taihang mountains显示文摘The region along the Taihang Mountains in the North China Plain(NCP) is characterized by serious fine particle pollution. To clarify the formation mechanism and controlling factors, an observational study was conducted to investigate the physical and chemical properties of the fine particulate matter in Jiaozuo city, China. Mass concentrations of the water-soluble ions(WSIs) in PM_(2.5) and gaseous pollutant precursors were measured on an hourly basis from December 1, 2017, to February 27, 2018. The positive matrix factorization(PMF) method and the FLEXible PARTicle(FLEXPART) model were employed to identify the sources of PM_(2.5). The results showed that the average mass concentration of PM_(2.5) was 111 μg/m^(3) during the observation period. Among the major WSIs, sulfate, nitrate, and ammonium(SNA) constituted 62% of the total PM_(2.5) mass, and NO_(3)^(-) ranked the highest with an average contribution of 24.6%. NH_(4)^(+) was abundant in most cases in Jiaozuo. According to chemical balance analysis, SO_(2)-4, NO_(3)^(-), and Cl^(-) might be present in the form of(NH_4)_(2)SO_4, NH_4NO_3, NH_4Cl, and KCl. The liquid-phase oxidation of SO_(2) and NO_(2) was severe during the haze period. The relative humidity and pH were the key factors influencing SO_(4)^(2-) formation. We found that NO_(3)^(-) mainly stemmed from homogeneous gas-phase reactions in the daytime and originated from the hydrolysis of N_(2)O_5 in the nighttime, which was inconsistent with previous studies. The PMF model identified five sources of PM_(2.5) : secondary origin(37.8%), vehicular emissions(34.7%), biomass burning(11.5%), coal combustion(9.4%), and crustal dust(6.6%). | Xiaoyong Liu Mingshi Wang Xiaole Pan Xiyue Wang Xiaolong Yue Donghui Zhang Zhigang Ma Yu Tian Hang Liu Shandong Lei Yuting Zhang Qi Liao Baozhu Ge Dawei Wang Jie Li Yele Sun Pingqing Fu Zifa Wang Hong He | 2021 | Journal of Environmental Sciences2021，33，5： | 5 |
| 12 | 3D numerical simulation of boreholes for gas drainage based on the pore–fracture dual media显示文摘A gas migration controlling equation was formulated based on the characteristics of the dual pore–fracture media of coal mass and in consideration of the matrix exchange between pores and fractures.A model of permeability dynamic evolution was established by analyzing the variation in effective stress during gas drainage and the action mechanism of the effect of coal matrix desorption on porosity and fracture in the coal body.A coupling model can then be obtained to characterize gas compressibility and coal deformability under the gas–solid coupling of loading coal.In addition,a 3D model of boreholes was established and solved for gas drainage based on the relevant physical parameters of real mines.The comparison and analysis results for the law of gas migration and the evolution of coal body permeability around the boreholes before and after gas extraction between the dual media and the single-seepage field models can provide a theoretical basis for further research on the action mechanism of gas drainage. | Wei Jianping Li Bo Wang Kai Sun Donghui | 2016 | International Journal of Mining Science and Technology2016，26，4： | 5 |
| 13 | Comparison of corrosion behavior of ZL104 alloy at as-cast and heat treatment states显示文摘The corrosion behavior of ZL104 alloy at different states(as-cast and heat treatment) in salt spray corrosion (SSC) was studied.The results show that the sample treated after refinement and modifciation has the least corrosive resistance compared with the sample bearing as -cast stucure at the beginning of the corrosion.As the corrosion process continued.however,the trend reversed itself.After 44h continuous corrosion,the corrosive rates of all samples tend to be stable.After experiments,the sample bearing as -cast structure had the most corrosive products on the surface whereas the sample being refined and modified had the least products.The Fourier transformation infrared spectroscopy(FTIR) analyses of the corrosion products show that these products are composed of hydroxyl-containing substances. | WANG Donghui, ZHENG Yankang, LI ianguo, and BAI BingzheDepartment of Materials Science and Engineering, Tsinghua University, Beijing 100084, China | 2002 | Rare Metals2002，21，3： | 4 |

| 15 | Impacts of CO_2-driven seawater acidification on survival,egg production rate and hatching success of four marine copepods显示文摘Ecological experiments were conducted to examine the effects of seawater containing elevated par- tial pressure of carbon dioxide (p CO2 800 × 10 -6 , 2 000 × 10 -6 , 5 000 × 10 -6 and 10 000 × 10 -6 ) on the survival and reproduction of female Acartia pacifica, Acartia spinicauda, Calanus sinicus and Centropages tenuiremis, which are the dominant copepods in the southern coastal waters of China. The results show that the effects of elevated p CO2 on the survival rates of copepods were species-specific. C. sinicus, which was a macro-copepod, had a higher survival rate (62.01%-71.96%) than the other three species (5.00%-26.67%) during the eight day exposure. The egg production rates of C. sinicus, A. spinicauda and C. tenuiremis were significantly inhibited by the increased p CO2 and the exposure time duration. There were significantly negative impacts on the egg hatching success of A. spinicauda and C. tenuiremis in the p CO2 2 000 × 10 -6 and 10 000 × 10 -6 groups, and, in addition, the exposure time had noticeably impacts on these rates too. This study indicates that the reproductive performances of copepods were sensitive to elevated p CO2 , and that the response of different copepod species to acidified seawater was different. Furthermore, the synergistic effects of seawater acidification and climate change or other pollutant stresses on organisms should be given more attention. | ZHANG Dajuan LI Shaojing WANG Guizhong GUO Donghui | 2011 | Acta Oceanologica Sinica2011，30，6： | 4 |
| 16 | Preparation of birnessite-supported Pt nanoparticles and their application in catalytic oxidation of formaldehyde显示文摘Flaky and nanospherical birnessite and birnessite-supported Pt catalysts were successfully prepared and characterized by means of Xray diffraction (XRD),transmission electron microscopy (TEM),energy dispersive spectroscopy (EDS) and N2 adsorption-desorption.Effects of the birnessite morphology and Pt reduction method on the catalytic activity for the complete oxidation of formaldehyde (HCHO) were investigated.It was found that flaky birnessite exhibited higher catalytic activity than nanospherical birnessite.The promoting effect of Pt on the birnessite catalyst indicated that the reduction method of the Pt precursor greatly influenced the catalytic performance.Flaky birnessite-supported Pt nanoparticles reduced by KBH 4 showed the highest catalytic activity and could completely oxidize HCHO into CO2 and H2O at 50℃,whereas the sample reduced using H2-plasma showed lower activity for HCHO oxidation.The differences in catalytic activity of these materials were jointly attributed to the effects of pore structure,surface active sites exposed to HCHO and the dispersion of Pt nanoparticles. | Linlin Liu Hua Tian Junhui He Donghui Wang Qiaowen Yang | 2012 | Journal of Environmental Sciences2012，24，6： | 4 |
| 17 | Optimization of binder addition and compression load for pelletization of wheat straw using response surface methodology显示文摘Densification is required for efficiently handling and transporting biomass as feedstock for biofuel production.Binders can enhance straw pellet strength and improve the pellet performance.The present investigation aimed to optimize binders and compression load for wheat straw pelletization using a single pelleting unit.Response surface methodology was employed by using a four-factor,five-level central composite design with wood residue(%,w/w),bentonite(%,w/w),crude glycerol(%,w/w),and compression load(N)as process parameters.The pellet tensile strength,specific energy consumption of pelleting,and pellet density were the response variables.The higher heating value,ash content of the pellet product and the cost of the feedstock were also considered in optimizing binder addition.The developed model fitted the data and was adequate for binder analysis and optimization.Wheat straw pellet,with the addition of 30% wood residue,0.80% bentonite,and 3.42% crude glycerol,in addition to 4000 N of compressive load,was identified as optimal with good performance of pellet tensile strength(1.14 MPa),specific energy consumption(32.6 kJ/kg),and pellet density(1094 kg/m^(3))as well as low ash content(6.13%)and high heating value(18.64 MJ/kg).Confirmation tests indicated high accuracy of the model. | Lu Donghui Lope G.Tabil Wang Decheng Wang Guanghui Wang Zhiqin | 2014 | International Journal of Agricultural and Biological Engineering2014，7，6： | 4 |
| 18 | Integrated risk assessment of complex disaster system based on a non-linear information dynamics model显示文摘This paper describes a non-linear information dynamics model for integrated risk assessment of complex disaster system from an evolution perspective. According to the occurrence and evolution of natural disaster system with complicated and nonlinear characteristics, a non-linear information dynamics mode is introduced based on the maximum flux principle during modeling process to study the integrated risk assessment of complex disaster system. Based on the non-equilibrium statistical mechanics method, a stochastic evolution equation of this system is established. The integrated risk assessment of complex disaster system can be achieved by giving reasonable weights of each evaluation index to stabilize the system. The new model reveals the formation pattern of risk grade and the dynamics law of evolution. Meanwhile, a method is developed to solve the dynamics evolution equations of complex system through the self-organization feature map algorithm. The proposed method has been used in complex disaster integrated risk assessment for 31 provinces, cities and autonomous regions in China mainland. The results have indicated that the model is objective and effective. | WANG Wei SU JingYu MA DongHui TIAN Jie | 2012 | Science China(Technological Sciences)2012，55，12： | 4 |
| 19 | Design of near-α Ti alloys via a cluster formula approach and their high-temperature oxidation resistance显示文摘The multi-component composition characteristics of high-temperature near-α Ti alloys were investigated in the present work by means of a cluster formula approach. The uniform cluster formula [CN12 cluster](glue atom)3 for the hexagonal close-packed α solid solution was first obtained based on the Friedel oscillation theory, with a total atom number in the formula of Z = 16. Then it was analyzed that the Z values in the cluster composition formulas of typical near-α Ti alloys are within the range of Z = 16.0016.30, being perfectly consistent with the ideal Z = 16. Based on it, a series of new alloys with Z = 16 and with Nb/Ta substitution for Mo in Ti1100 alloy were designed, suction-cast into φ 6 mm rods, and then heat-treated with solid solution and aging. It was found that the alloy with co-addition of Mo, Ta and Nb has a high strength and good ductility at both room and high temperatures. More importantly, the additions of Nb and Ta can contribute to the formation of continuous and compact Al2O3 scales, resulting in an obvious improvement of oxidation resistances at both 923 K and 1073 K. The effects of Mo, Ta and Nb on the oxidation behaviors of the designed alloys at 1073 K were further discussed. | Beibei Jiang Donghui Wen Qing Wang Jinda Che Chuang Dong Peter K.

| 20 | Improved dispersion performance and interfacial compatibility of covalent-grafted MOFs in mixed-matrix membranes for gas separation显示文摘Mixed-matrix membranes(MMMs)have received much attention due to their processable advantages of polymer and high permeability and/or selectivity of porous metal-organic frameworks(MOFs)fillers.However,the interfacial defects caused by poor interaction between MOFs with polymers and the agglomeration phenomenon caused by uneven dispersion of MOFs are common problems in mixed-matrix membranes.Currently,the priming protocol is one of solutions to the above problems,but it cannot precisely regulate the dispersion of particles and the interfacial compatibility between two phases.Herein,covalent grafting of polyimide 6FDA-Durene onto the surface of UiO-66-NH2 can mitigate the aggregation of fillers inside the polymeric matrices and improve the interfacial interaction between two phases,thus significantly improving the CO_(2)/CH_(4)separation performance on the as-synthesized MMMs.The explored gas transport mechanism indicated that the improved separation was due to the raise of solubility selectivity.Furthermore,the stronger covalent bond between fillers and polyimide than physical interaction of priming protocol also endows the improved anti-plasticization phenomenon for CO_(2)/CH_(4)separation. | Chongqing Wang Guangjie Ren Kaifeng Wei Donghui Liu Tingting Wu Jinlong Jiang Junfeng Qian Yichang Pan | 2021 | Green Chemical Engineering2021，2，1： | 3 |
