| 1 | 5H-dithieno[3,2-b:20,30-d]pyran-5-one unit yields efficient wide-bandgap polymer donors显示文摘Recently,great progress has been made in organic solar cells due to the emergence of high-performance nonfullerene acceptors[1-6].Over 16%and 17%power conversion efficiencies(PCEs)were achieved for nonfullerene-acceptor-based single-junction and tandem cells,respectively[7,8].Owing to complementary light absorption,wide-bandgap donor-acceptor(D-A)copolymers are ideal electron-donating partners for nonfullerene acceptors.However,efficient D-A copolymer donors are still limited. | Jinfeng Liu Ling Liu Chuantian Zuo Zuo Xiao Yingping Zou Zhiwen Jin Liming Ding | 2019 | Science Bulletin2019，64，22： | 13 |
| 2 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 3 | An experimental method for squealer tip flow field considering relative casing motion显示文摘Squealer tip is widely used in turbines to reduce tip leakage loss.In typical turbine environment,the squealer tip leakage flow is affected by multiple factors such as the relative casing motion and the wide range of variable incidence angles.The development of experimental methods which can accurately model the real turbine environment and influencing factors is of great significance to study the squealer tip leakage flow mechanism.In the present paper,a low-speed turbine cascade test facility which can model the relative casing motion and wide range of variable incidence angles(-25°to 55°)is built.Based on the similarity criteria,a high-low speed similarity transformation method of the turbine cascade is established by considering the thickness of the turbine blade.A combined testing method of Particle Image Velocimetry(PIV)and local pressure measurement is proposed to obtain the complex flow structures within the tip cavity.The results show that the experimental method can successfully model the relative casing motion and the wide range of variable incidence angles.The low-speed cascade obtained by the similarity transformation can model the high-speed flow accurately.The measurement technique developed can obtain the complex flow field and successfully capture the scraping vortex within the squealer tip. | Fei ZENG Jinlin DU Lin HUANG Liming XUAN Qiang ZHAO Zhengping ZOU | 2020 | Chinese Journal of Aeronautics2020，33，7： | 8 |
| 4 | Solute-homogenization model and its experimental verification in Mg-Gd-based alloys显示文摘Composition homogenization in solid solution is important for industrial alloys. In the present work, a solute homogenization model is proposed based on the chemical short-range-order tendency in Mg-Gdbased alloys. After a calculation using the cluster-plus-glue-atom model, the stable Mg-Gd structural unit is derived, [Gd-Mg12]Mg6, where one solute Gd is nearest-neighbored with twelve Mg atoms to form the characteristic hcp cluster [Gd-Mg12] and this cluster is matched with six Mg glue atoms. Such a local unit is then mixed with [Mg-Mg12]Mg3, the stable unit for pure Mg. Assuming that the Gd-containing units are arranged in fcc-or bcc-like lattice points and the Mg units in their octahedral interstices, three proportions between the two units are obtained, 1:1, 2:3, and 1:3, which constitute three solute homogenization modes. The prevailing Mg-Gd-based alloys are consequently classified into three groups, respectively exemplified by GW103 K(Mg-10 Gd-3 Y-0.4 Zr, wt%), GW83 K(Mg-8 Gd-3 Y-0.4 Zr), and GW63 K(Mg-6 Gd-3 Y-0.4 Zr). Mg-Gd-Y-Zr alloys were designed following the model(where Y and Zr were also added in substitution for Gd) and prepared by permanent-mould casting. According to their mechanical properties,the 1:3 alloy(Mg-5.9 Gd-1.6 Y-0.4 Zr) shows the best comprehensive properties(ultimate tensile strength305 MPa, yield strength 186 MPa, elongation 9.0%) in solution plus ageing state. | Shengnan Qian Chuang Dong Tianyu Liu Ying Qin Qing Wang Yujuan Wu Lidong Gu Jianxin Zou Xiangwen Heng Liming Peng Xiaoqin Zeng | 2018 | Journal of Materials Science & Technology2018，34，7： | 6 |
| 5 | Rapid qualitative and quantitative analysis of strong aroma base liquor based on SPME-MS combined with chemometrics显示文摘To objectively classify and evaluate the strong aroma base liquors(SABLs)of different grades,solid-phase microextraction-mass spectrometry(SPME-MS)combined with chemometrics were used.Results showed that SPME-MS combined with a back-propagation artificial neural network(BPANN)method yielded almost the same recognition performance compared to linear discriminant analysis(LDA)in distinguishing different grades of SABL,with 84%recognition rate for the test set.Partial least squares(PLS),successive projection algorithm partial least squares(SPA-PLS)model,and competitive adaptive reweighed samplingpartial least squares(CARS-PLS)were established for the prediction of the four esters in the SABL.CARS-PLS model showed a greater advantage in the quantitative analysis of ethyl acetate,ethyl butyrate,ethyl caproate,and ethyl lactate.These results corroborated the hypothesis that SPME-MS combined with chemometrics can effectively achieve an accurate determination of different grades of SABL and prediction performance of esters. | Zongbao Sun Junkui Li Jianfeng Wu Xiaobo Zou Chi-Tang Ho Liming Liang Xiaojing Yan Xuan Zhou | 2021 | Food Science and Human Wellness2021，10，3： | 3 |
| 6 | Effect of heat treatment on strain–controlled fatigue behavior of cast Mg–Nd–Zn–Zr alloy显示文摘The influence of heat treatment on the strain-controlled fatigue behavior of cast NZ30 K alloy was investigated. Compared with the as-cast and solutionized(T4) alloys, the peak-aged(T6) and over-aged(T7)counterparts have a higher cyclic stress and a lower plastic strain value due to the precipitation strengthening. The as-cast and T4-treated alloys have a higher fatigue strength/yield strength ratio than the aged alloys, which is mainly attributed to their higher cyclic hardening. Under stress-controlled loading,the aged alloys show lower hysteresis energies than the as-cast and T4-treated counterparts, leading to longer fatigue lifetimes. For the T4-treated alloy, the cyclic hardening and fatigue failure are controlled by the dislocations-slip and twinning, while for both the as-cast and T6-treated counterparts, they are controlled by the dislocation-slip. For the T7-treated alloy, cyclic deformation and failure behavior are mainly dependent on dislocations-slip and grain boundary sliding. | Zhenming Li Qigui Wang Alan A.Luo Jichun Dai Hui Zou Liming Peng | 2018 | Journal of Materials Science & Technology2018，34，11： | 2 |

| 9 | A novel clustered SPIO nanoplatform with enhanced magnetic resonance T2 relaxation rate for micro-tumor detection and photothermal synergistic therapy显示文摘Construction of micro tumor sensitive theranostic nanoagents that can increase the accuracy of imaging diagnosis and boost the therapeutic efficacy has been demonstrated for a promising approach for diagnosis and treatment of cancer.Herein,we reported a novel super-paramagnetic iron oxide(SPIO)based nanoplatform that possess significantly enhanced magnetic resonance property and photothermal effect for tumor theranostic purpose.This polyethylene glycol with four phenylboronic acid(PEG-B4)/CNTs@porphyrin(ph)/SPIO(BCPS)nanoplatform was simply prepared via integrated SPIO,ph,and a novel dendrimer with PEG liner and four PBA groups(PEG-B4)on the surface of carbon nanotubes(CNTs).Subsequently,a significant T2 relaxation rate enhanced can be achieved by the reduced accessibility of water to SPIO clustering.Moreover,the synergetic enhanced photothermal from BCPS nanoplatform contributed to better photothermal effect for cancer therapy.Furthermore,the targeting ability to sialic acid overexpressed tumor was further introduced from phenylboronic acid from PEG-B4.We showed that BCPS nanoplatform could not only selectively identify solid tumors and detect micro-sized metastatic tumor(1 mm)in the liver,but also effectively ablate tumors in a xenograft model,thereby achieving a complete cure rate of 100%at low laser dose.Our results highlight the potential of BCPS nanoplatform for accurate micro-tumor diagnosis and effective tumor therapy. | Hongwei Lu Yongjing Xu Ruirui Qiao Ziwei Lu Pin Wang Xindan Zhang An Chen Liming Zou Zhongling Wang | 2020 | Nano Research2020，13，8： | 1 |
| 10 | ANOMALOUS STRAIN RATE DEPENDENCE OF FLOW STRESS IN TiAl INTERMETALLIC COMPOUNDS显示文摘Plastic deformation of TiAI and TiAI-V intermetallic compounds has been studied by com-pression experiment at various temperatures and strain rates.Results show that the plasticdeformation in distinct temperature range is principally controlled by the mechanisms ofPeierls-Nabarro,cross slip and creep of dislocations.For TiAI-V alloy deformed at a rangeof 600—700 K,the negative strain rate dependence of flow stress was observed,i.e.,the morethe plastic strain is.the more the negative dependence will be.A possible mechanism of theanomaly could be interpreted by thermal activation of dislocation cross slipping.The effects oftemperature and strain rate on work-hardening exponent were also studied and discussed. | WANG Liming ZHU Dong YAO Mei CAI Qigong ZOU Dunxu State Key Laboratory for Fatigue and Fracture of Materials,Academia Sinica,Shenyang Central Iron and Steel Research Institute,Ministry of Metallurgical Industry,Beijing,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，5： | 1 |

| 14 | Fatigue characteristics of sand-cast AZ91D magnesium alloy显示文摘The fatigue characteristics of the AZ91D-T6 alloy samples taken from engine blocks have been investigated at 20℃ and elevated temperature(150℃).The fatigue strength and cyclic stress amplitude of the alloy significantly decrease with the increase of the test temperature,although cyclic hardening occurs continuously until failure for both temperatures.With the increase of the temperature,the decreased fatigue life of the alloy tested at the same stress amplitude is mainly attributed to the decreased matrix strength and the increased hysteresis energies.Fatigue failure of the engine blocks made of AZ91D-T6 alloy is mainly controlled by casting defects.For the defect-free specimens,the crack initiation behavior is determined by the single-slip(20℃)and by environment-assisted cyclic slip(150℃)during fatigue,respectively.The low-cycle fatigue lives of the alloy can be predicted using the Coffin-Manson relation and Basquin laws,the three-parameter equation and the energy-based concepts,while the high-cycle fatigue lives of the alloy fitted well with the developed long crack life model and MSF life models. | Zhenming Li Alan ALuo Qigui Wang Hui Zou Jichun Dai Liming Peng | 2017 | Journal of Magnesium and Alloys2017，5，1： | 1 |
| 15 | Tuning the bandgap of double perovskites显示文摘With great achievements in efficiency,stability,and large-scale preparation of perovskite solar cells(PSCs),the com-mercialization of PSC is ongoing,but there is still an issue on lead toxicity.Although lead content in the device is low,the water solubility of lead salts leads to potential environmental pollution.At present,the non-lead perovskites studied in-clude:divalent metal perovskite(e.g.,Sn^(2+),Ge^(2+),Cu^(2+)),trivalent metal perovskite(e.g.,Bi^(3+),Sb^(3+),In^(3+)),tetravalent met-al double perovskite(e.g.,Sn^(4+),Pd^(4+),Ti^(4+),Pt^(4+))and mono-trivalent mixed double perovskite(e.g.,Ag+and Bi^(3+),Ag+and In^(3+),Ag^(+)and Sb^(3+)).Their properties are summarized in Table 1.Since the first report on non-lead double perovskite Cs2AgBiBr6 in 2016^([1]). | Yu Zou Wenjin Yu Lixiu Zhang Cuncun Wu Lixin Xiao Liming Ding | 2021 | Journal of Semiconductors2021，42，12： | 0 |
| 16 | Aggregate Point Cloud Geometric Features for Processing显示文摘As 3D acquisition technology develops and 3D sensors become increasingly affordable,large quantities of 3D point cloud data are emerging.How to effectively learn and extract the geometric features from these point clouds has become an urgent problem to be solved.The point cloud geometric information is hidden in disordered,unstructured points,making point cloud analysis a very challenging problem.To address this problem,we propose a novel network framework,called Tree Graph Network(TGNet),which can sample,group,and aggregate local geometric features.Specifically,we construct a Tree Graph by explicit rules,which consists of curves extending in all directions in point cloud feature space,and then aggregate the features of the graph through a cross-attention mechanism.In this way,we incorporate more point cloud geometric structure information into the representation of local geometric features,which makes our network perform better.Our model performs well on several basic point clouds processing tasks such as classification,segmentation,and normal estimation,demonstrating the effectiveness and superiority of our network.Furthermore,we provide ablation experiments and visualizations to better understand our network. | Yinghao Li Renbo Xia Jibin Zhao Yueling Chen Liming Tao Hangbo Zou Tao Zhang | 2023 | Computer Modeling in Engineering & Sciences2023，，7： | 0 |
| 17 | Aerophilic Triphase Interface Tuned by Carbon Dots Driving Durable and Flexible Rechargeable Zn‑Air Batteries显示文摘Efficient bifunctional catalysts for oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)are vital for rechargeable Zn-air batteries(ZABs).Herein,an oxygen-respirable sponge-like Co@C–O–Cs catalyst with oxygen-rich active sites was designed and constructed for both ORR and OER by a facile carbon dot-assisted strategy.The aerophilic triphase interface of Co@C–O–Cs cathode efficiently boosts oxygen diffusion and transfer.The theoretical calculations and experimental studies revealed that the Co–C–COC active sites can redistribute the local charge density and lower the reaction energy barrier.The Co@C–O–Cs catalyst displays superior bifunctional catalytic activities with a half-wave potential of 0.82 V for ORR and an ultralow overpotential of 294 mV at 10 mA cm^(−2) for OER.Moreover,it can drive the liquid ZABs with high peak power density(106.4 mW cm^(−2)),specific capacity(720.7 mAh g^(−1)),outstanding long-term cycle stability(over 750 cycles at 10 mA cm^(−2)),and exhibits excellent feasibility in flexible all-solid-state ZABs.These findings provide new insights into the rational design of efficient bifunctional oxygen catalysts in rechargeable metal-air batteries. | Kuixing Ding Yu Ye Jiugang Hu Liming Zhao Wei Jin Jia Luo Shan Cai Baicheng Weng Guoqiang Zou Hongshuai Hou Xiaobo Ji | 2023 | Nano-Micro Letters2023，15，2： | 0 |
| 18 | Traffic An o ma ly De te ctio n in Backbone Networks Using C la s s ifica tio n o f M u Itid ime n s io n a I Time Series of Entropy显示文摘Detecting traffic anomalies is essential for diagnosing attacks. High-Speed Backbone Networks (HSBN) require Traffic Anomaly Detection Systems (TADS) which are accurate (high detection and low false positive rates) and efficient. The proposed approach utilizes entropy as traffic distributions metric over some traffic dimensions. An efficient algorithm, having low computational and space complexity, is used to estimate entropy. Entropy values over all dimensions are collected to form a detection vector for every sliding window. One class support vector machine classifies all detection vectors into one of two groups: abnormal vectors and normal vectors. A Multi-Windows Correlation Algorithm (MWCA) calculates comprehensive anomaly scores observed in a sequence of windows in order to reduce false positive rates and obtain high detection rates. Some real-world traffic traces have been used to validate and evaluate the efficiency and accuracy of this system through three experiments. In Experiment 1, the estimating algorithm of entropy which costs less memory and runs faster than traditional algorithms is more suitable for detection anomalies. In Experiment 2, the classification and correlation algorithms can improve the detection accuracy significantly. Experiment 3 compares the subject system and three well-known systems. Ours system is the most accurate one. Those results have indicated that the proposed system significantly improves the accuracy and efficiency. | Zheng Liming Zou Peng Jia Yan Han Weihong | 2012 | China Communications2012，9，7： | 0 |

| 20 | Speech Recognition for Parkinson’s Disease Based on Improved Genetic Algorithm and Data Enhancement Technology显示文摘Parkinson’s disease is one of the most destructive diseases to the nervous system.Speech disorder is one of the typical symptoms of Parkinson’s disease.Approximately 90%of Parkin-son’s patients develop some degree of speech disorder,which affects speech function faster than any other subsystem of the body.Screening Parkinson’s disease by sound is a very effective method that has attracted a growing number of researchers over the past decade.Patients with Parkinson’s disease could be identified by recording the sound signal of the pronunciation of words,extracting appropriate features and identifying the disturbance in their voices.This paper proposes an improved genetic algorithm combined with a data enhancement method for Parkinson’s speech signal recognition.Specifically,the methods first extract representative speech signal features through the L1 regularization SVM and then enhance the representative feature data by the SMOTE algorithm.Following this,both original and enhanced features are used to train an SVM classifier for speech signal recognition.An improved genetic algorithm was applied to find the optimal parameters of the SVM.The effectiveness of our proposed model is demonstrated by using Parkinson’s disease audio data set from the UCI machine learning library,and compared with the most advancedmethods,our proposed method has the best performance. | Jing Qin Tong Liu Zumin Wang Qijie Zou Liming Chen Chang Hong | 2022 | 国际计算机前沿大会会议论文集2022，，1： | 0 |
