| 1 | Response of the accumulation of proline in the bodies of Populus euphratica to the change of groundwater level at the lower reaches of Tarim River显示文摘The content of proline in the plant bodies is closely related to the converse-succession-resistant capability of the plants. In this paper, the relationship between the proline accumulation in the bodies of Populus euphratica and the change of groundwater level is analyzed by taking Popu-lus euphratica, the main community-building species of the desert riparian forests along the Tarim River, as the research object. The research results show that the accumulation of proline in the bodies of Populus euphratica is closely related to the change of groundwater level gradient under drought stress, it increases with the drawdown of groundwater level and the increase of moisture stress degree; the accumulation of proline in the bodies of Populus euphratica has two ex-tremely high points at the groundwater depth ranges of 3.64—5.14 m and 9.46—10.16 m. Combining the field investiga-tion and the analysis of the plots, it is considered that the groundwater level of 3.5—4.5 m is rational for the growth of Populus euphratica. The stress groundwater depth for the normal growth and the critical one for the survival of Popu-lus euphratica are below 4.5 m and 9—10 m respectively at the lower reaches of the Tarim River. | Yaning Chen Yapeng Chen Weihong Li Hongfeng Zhang | 2003 | Chinese Science Bulletin2003，48，18： | 31 |
| 2 | Determining method and conditional factors of electrochemical fingerprint of Chinese traditional medicine显示文摘The thermodynamic systems and kinetic model suitable for the electrochemical token of the compo-nent throng in Chinese traditional medicines have been analyzed. It has been indicated that the damp oscillatory reactions in the non-equilibrium close system and open system without the supplement of dissipative substance have important significance for the throng token and analysis of chemical com-ponents in Chinese traditional medicines. Various factors influencing the electrochemical fingerprint,such as reactant species and their concentrations,electrode types,temperature,stir rate,the kind,dosage and granularity of Chinese traditional medicines,have amply been researched by the B-Z os-cillatory reaction which used malonic acid as a main dissipative substance. In addition,the quantitative information about the chemical components in Chinese traditional medicines has been discussed in detail. The method and its conditions for determining the electrochemical fingerprint used in scientifi-cally distinguishing and evaluating Chinese traditional medicines have successfully been put forward. | ZHANG TaiMingt LIANG YiZeng YUAN Bin DING Feng ZHANG YaPeng WEI ManQiong CHEN Xu | 2007 | Chinese Science Bulletin2007，52，16： | 22 |
| 3 | Principle, traits and functions of electrochemical fingerprint of Chinese traditional medicine显示文摘In regard to such challenging analysis problems as scientific identification and quality evaluation of Chinese traditional medicine, the electrochemical fingerprint technique of Chinese traditional medi- cine has been researched. The principle, traits, functions, etc., of the electrochemical fingerprint have detailedly been analyzed and discussed by the B-Z oscillatory system using malonic acid as main dissipation substance, characterized by the fact that different influences of different Chinese traditional medicines on the mechanism of the oscillatory reaction cause different changes of the shape of the potential-time curve of the oscillatory system under the conditions of constant tem- perature and pressure. An economical, simple and convenient, easy pushing and effective scientific method for distinguishing and evaluating multifarious Chinese traditional medicines has success- fully been put forward. | ZHANG TaiMing LIANG YiZeng YUAN Bin DING Feng ZHANG YaPeng CHEN WenYan | 2007 | Chinese Science Bulletin2007，52，20： | 16 |
| 4 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020，63，8： | 7 |
| 5 | Anti-P-selectin lectin-EGF domain monoclonal antibody inhibits the maturation of human immature dendritic cells显示文摘Dendritic cells(DCs) are professinal antigen-presenting cells with the ability to initiate primary Tcell responses. While it iswell known that inflammatory stimuli induce the functional maturation of immature DCs, whether adhesion molecule selectins regulate DCmaturation is poorly understood. Using anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb) that blocks the adhesionof P-, E-, and L-selectin, we demonstrate herein that selectins play important role in stimulating functional maturation of immature DCs.Immature DCs are generated from human cord blood CD34+hematopoietic stem/progenitor cells that were cultured in the presence of stemcell factor, Fms-like tyrosine-kinase-3 ligand, granulocyte-macrophage colony stimulating factor, and transform growth factor-β1. Whenstimulated with tumor necrosis factor-alpha(TNF-α), immature DCs differentiated into mature DCs, producing increased levels of costim-ulatory molecules and interleukin (IL)-12 and obtaining the ability to potently activate naive Tcells. Interestingly, in contrast to matureDCs derived from TNF-α-induced immature DC cultures without PsL-EGFmAb, immature DCs treated with PsL-EGFmAb for7 days werecompletely blocked their maturation, as evidenced by decreased expression of costimulatory molecules CD80, CD86, and CD83, inhibi-ted production of IL-12, and inability to activate naive Tcellsin vitro. Thus, blockade of selectins using PsL-EGFmAb will prove to bea valuable tool for the study of the molecuar mechanisms of DC maturation, as well as for the prevention and treatment of DC-mediated au-toimmunity. | Tong Zhou Yanyu Zhang Guizhi Sun Yumei Zhang Dongqing Zhang Yapeng Zhao Nan Chen | 2006 | 上海交通大学学报(医学版)2006，26，5： | 5 |
| 6 | Enhanced tribological properties of aligned graphene-epoxy composites显示文摘The random distribution of graphene in epoxy matrix hinders the further applications of grapheneepoxy composites in the field of tribology.Hence,in order to fully utilize the anisotropic properties of graphene,highly aligned graphene-epoxy composites(AGEC)with horizontally oriented structure have been fabricated via an improved vacuum filtration freeze-drying method.The frictional tests results indicated that the wear rate of AGEC slowly increased from 5.19x10^(-6)mm^(3)/(N-m)to 2.87x10^(-5)mm^(3)/(N-m)with the increasing of the normal load from 2 to 10 N,whereas the friction coefficient(COF)remained a constant of 0.109.Compared to the neat epoxy and random graphene-epoxy composites(RGEC),the COF of AGEC was reduced by 87.5%and 71.2%,and the reduction of wear rate was 86.6%and 85.4%at most,respectively.Scanning electron microscope(SEM)observations illustrated that a compact graphene self-lubricant film was formed on the worn surface of AGEC,which enables AGEC to possess excellent tribological performance.Finally,in light of the excellent tribological properties of AGEC,this study highlights a pathway to expand the tribological applications of graphene-epoxy composites. | Yuefeng DU Zhenyu ZHANG Dong WANG Lezhen ZHANG Junfeng CUI Yapeng CHEN Mingliang WU Ruiyang KANG Yunxiang LU Jinhong YU Nan JIANG | 2022 | Friction2022，10，6： | 2 |
| 7 | Repairing skull defects in children with nano-hap/collagen composites: A clinical report of thirteen cases显示文摘Objective:To evaluate the clinical results of repairing skull defects with biomimetic bone(nano-hap/collagen composites,NHACs)in children.Methods:Thirteen children with skull defects were treated with NHACs in our hospital.The NHACs molded with the help of a 3D printer were used in the operations.Results:All 13 operations were successful,and patients recovered without infection.Only one patient suffered from subcutaneous hydrops post-operation.The implanted NHACs remained fixed well after 1 year,and their CT HU values raised gradually.Skull shapes of children developed normally.Recovery of neurological and cognitive function was significant.Conclusions:NHAC,chosen to repair skull defects in children,can coexist with normal skull and reduce the negative effects on growth and development.NHAC could be a good choice for children with skull defects. | Tuoyu Chen Yuqi Zhang Huancong Zuo Yapeng Zhao Chaoqiang Xue Bin Luo Qinglin Zhang Jin Zhu Xiumei Wang Fuzhai Cui | 2016 | Translational Neuroscience and Clinics2016，2，1： | 2 |
| 8 | Agronomic cultivation measures on productivity of oilseed flax:A review显示文摘Oilseed flax is one of the most important oil crops in China.With the improvement of people's living standards and the deepening knowledge of the nutritional value of oilseed flax,the demand and economic value of oilseed flax are increasing,and the cultivated area in China is expanding.However,the grain yield of oilseed flax is lower than other oil crops.It varies significantly from year to year,combined with a lower degree of mechanization,which has greatly limited the healthy development of the flax industry.Some of the effects of agronomic measures on productivity and water use efficiency of oilseed flax are reviewed in this paper.The major agronomic strategies for the productivity of oilseed flax were presented based on fertilization,plant density,irrigation,cropping pattern and weed control.Future research should investigate the effect of silicon and potassium fertilizers on the mechanism of lodging resistance of oilseed flax,the effects of diversified cropping systems(strip intercropping and crop rotation)on high and stable productivity and efficient utilization of resources. | Zhengjun Cui Bin Yan Yuhong Gao Bing Wu Yifan Wang Haidi Wang Peng Xu Bangqing Zhao Zhi Cao Yong Zhang Yaping Xie Yapeng Hu Xingbang Ma Junyi Niu | 2022 | Oil Crop Science2022，7，1： | 1 |

| 10 | Synthesis, Characterization, and Reactivity of Metalla- Chalcogenirenium Compounds显示文摘Chalcogenirenium cations,featuring an unsaturated three-membered organic ring,are limited but known to be synthesizable from alkynes with bulky electron-donating groups.Metalla-chalcogenirenium compounds have been synthesized as stable compounds through the reactions of a cyclic metal-carbyne complex-metallapentalyne with PhSCI,PhSeCI or PhTeCI.As a result of the high strain in the three-membered metallacycles,the metalla-chalcogenirenium cations react readily with the base or chloride ions.These reactions furnish a series of unprecedented chalcogenirenium cations with intact M=C bonds.The intrinsic stabilization effect of aromaticity is further elucidated by density functional calculations. | Ming Luo Yapeng Cai Xinlei Lin Lipeng Long Hong Zhang Haiping Xia | 2021 | Chinese Journal of Chemistry2021，39，6： | 1 |
| 11 | THERMOMECHANICAL RESPONSE OF SMA FIBER COMPOSITES WITH NON-UNIFORM TEMPERATURE DISTRIBUTION显示文摘A micromechanics method based on the High-Order-Theory developed by Aboudi et al. is used to predict the thermomechanical response of composites reinforced by shape memory alloy (SMA) fibers, and the non-uniform thermal distribution in composite arising from the process of heating or cooling is considered. The numerical development based on this model was coded to predict the thermomechanical response of shape memory alloy fiber/elastomer matrix composite subjected to thermal cycle loading. When the composite is heated, two heating ways, thermal gradients and heat source by passing an electric current through the SMA fibers are imposed on the composite respectively. Upon cooling, the first thermal boundary condition and the second thermal boundary condition are subjected to the composite respectively. A series of stress distributions and temperature distributions for different instants are calculated to reveal the interaction between the SMA material and matrix. It is useful to analyze and design the SMA actuator driven by heat source or the surface temperature. | Zhang Zhen Wang Jian Shen Yapeng (The State Key Laboratory of Mechanical Structural and Vibration,Xi’an Jiaotong University,Xi’an 710049,China) | 2003 | Acta Mechanica Solida Sinica2003，16，4： | 1 |
| 12 | Chemoenzymatic synthesis amphiphilic H-shaped copolymer and its self-assembly behavior显示文摘ABA triblock copolymers were synthesized by dihydroxyl-capped PEO initiated enzymatic ring-opening polymerization (eROP) of ε-CL in the presence of biocatalyst Novozyme 435. The chains ended with hydroxyl of block copolymers were modified by the esterification of 2,2-dichloro acetyl chloride (DCAC) to obtain the tetrafunctional macroinitiator,which was used in the ATRP of 4-vinylpyridine (4-VP). CuCl/HMTETA was used as the catalyst system in the ATRP of 4-VP to acquire the H-shaped block copolymers (PVP)2-b-PCL-b-PEG-b-PCL-b-(PVP)2. The H-shaped block copolymers were characterized by FTIR,NMR,and GPC. Copolymers with high molecular weights (Mn = 46121 g/mol) and low polydispersities (Mw/Mn = 1.30) were prepared. Moreover,the morphology of the copolymer was examined with dynamic light scattering (DLS) and atomic force microscopy (AFM). Spherical micelles with a diameter of 70 nm in aqueous solution were obtained. | ShuWei Wang Bao Zhang Peng Ai Ming Zhu Wei Wang ZhongPeng Sa LiNa Ma YaPeng Li | 2009 | Science China Chemistry2009，52，12： | 1 |
| 13 | Assessment of the electrical penetration of cell membranes using four-frequency impedance cytometry显示文摘The electrical penetration of the cell membrane is vital for determining the cell interior via impedance cytometry.Herein,we propose a method for determining the conductivity of the cell membrane through the tilting levels of impedance puises.When electrical penetration occurs,a high-frequency current freely passes through the cell membrane;thus,the intracellular distribution can directly act on the high-frequency impedance pulses.Numerical simulation shows that an uneven intracellular component distribution can affect the tilting levels of impedance pulses,and the tilting levels start increasing when the cell membrane is electrically penetrated.Experimental evidence shows that higher detection frequencies(>7 MHz)lead to a wider distribution of the tilting levels of impedance pulses when measuring cell populations with four-frequency impedance cytometry.This finding allows us to determine that a detection frequency of 7 MHz is able to pass through the membrane of Euglena gracilis(E.gracilis)cells.Additionally,we provide a possible application of four-frequency impedance cytometry in the biomass monitoring of single E.grailis cells.High-frequency impedance(≥7 MHz)can be applied to monitor these biomass changes,and low-frequency impedance(<7 MHz)can be applied to track the corresponding biovolume changes.Overall,this work demonstrates an easy determination method for the electrical penetration of the cell membrane,and the proposed platform is applicable for the multiparameter assessment of the cell state during cultivation. | Tao Tang Xun Liu Yapeng Yuan Tianlong Zhang Ryota Krya Yang Yang Kengo Suzuki Yo Tanaka Ming Li Yoichiroh Hosokawa Yaxiaer Yalikun | 2022 | Microsystems & Nanoengineering2022，8，3： | 0 |
| 14 | Zinc finger transcription factor ZAT family genes confer multi-tolerances in Gossypium hirsutum L.显示文摘ZAT(Zinc Finger of Arabidopsis thaliana)proteins are composed of a plant-specific transcription factor family,which play an important role in plant growth,development,and stress resista nee.To study the potential function of ZAT family in cotton,the whole genome identification,expression,and structure analysis of ZAT gene family were carried out.In this study,our analysis revealed the presenee of 115Z 56,59,and 115 ZAT genes in Gossypium hirsutum,G raimondii,G.arboreum and G barbadense,respectively.According to the number of domains and phylogenetic characteristics,we divided ZAT genes of four Gossypium species into 4 different clades,and further divided them into 11 subfamilies.The results of collinearity an alysis showed that segmental duplicati on was the main method to amplify the cotton ZAT genes family.Analysis of c/s-elements of promoters indicated that most GhZAT genes contained c/5-elements related to plant hormones and abiotic stress.According to heatmap analysis,the expression patterns of GhZAT genes under different stresses indicated that GhZAT genes were significantly involved in the response to cold,heat,salt,and PEG stress,possibly through different mechanisms.Among the highly expressed genes,we cloned a G hirsutum gene GhZAT67.Through virus-induced gene silencing(VIGS),we found that its expression level decreased significantly after being sileneed.Under alkaline treatment,the wilting degree of silenced plants was even greater than the wild type,which proved that GhZAT67 gene was involved in the response to alkaline stress. | FAN Yapeng ZHANG Yuexin RUI Cun XU Nan ZHANG Hong WANG Jing MALIK Waqar Afeal HAN Mingge ZHAO Lanjie LU Xuke CHEN Xiugui CHEN Chao YE Wuwei | 2021 | Journal of Cotton Research2021，4，3： | 0 |

| 16 | A high-accuracy DCO with hybrid architecture显示文摘In this paper, a novel hybrid digital-controlled oscillator(DCO) is proposed, which is used to improve the accuracy of the all-digital clock generator without reference source. The DCO with hybrid architecture consists of two parts: DCO_high and DCO_low. The DCO_high decides the coarse output frequency of DCO, and adopts the cascade structure to decrease the area. The DCO_low adopts the chain structure with three-state buffer, and decides the fine output frequency of DCO. Compared with traditional cascade DCO, the proposed hybrid DCO features higher precision with less inherent delay. Therefore the clock generator can tolerate process, voltage and temperature(PVT) variation and meet the needs of different conditions. The DCO is designed in SMIC 180 nm CMOS process with 0.021 mm^2 chip area. The output frequency is adjusted from 15–120 MHz. The frequency error is less than 0.83% at 25 MHz with 1.6–1.8 V supply voltage and 0–80℃ temperature variations in TT, FF,SS corners. | Yapeng Sun Huidong Zhao Shushan Qiao Yong Hei Fuhai Zhang | 2017 | Journal of Semiconductors2017，38，7： | 0 |
| 17 | 1-21 Study the in-medium Effect of K- by the ∧ Hyperon Production in Ni+Ni at 1.91 AGeV显示文摘Since the quark strongly couples to the ￣qq pairs in vacuum, the chiral symmetry is spontaneously broken in theQCD ground state. This mechanism generates more than 90% of hadron mass[1]. In hot and dense environment,the quark condensate, i.e. the ground state expectation value of the scalar quark density, is expected to decrease.At nuclear saturation density 0, the magnitude of the quark condensate is predicted to be reduced by about 1/3from its value in vacuum[2]. In such an environment, the properties of a hadron, like its decay width ?? and mass,are expected to change, and this is the so-called in-medium effect (IME). Theoretical it is predicted that the massof K? would decrease with increasing the medium density[2], due to a strong K?N attractive interaction. | Zhang Yapeng | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 18 | Malignant transformation and treatment of cystic mixed germ cell tumor显示文摘Objective:The authors report an extremely unusual presentation and management of a children pineal mixed germ cell tumor mainly composed of immature teratoma,aiming to summarize main theraptic points by literature review.Methods:A cystic lesion located in the rear of third ventricle in a child was detected3 years ago with no other therapy performed except for a ventriculo-peritoneal shunt.During the following 3 years,intermitted regular brain MRI demonstrated no evidence of lesion aggrandizement.However from 20 days before admission to our institute the patient began to present acutely with exacerbating clinical symptoms meanwhile brain MRI showed signs of abrupt revulsions of initial lesion without any incentive cause.Neurological examination revealed a significant rising of serum tumor marker level.Then surgical resection was performed immediately after admission which was followed by correlative two-course chemotherapy.Results:Postoperative brain MRI demonstrated totally removing of the lesion in rear of third ventricle.Serum tumor marker level decreased remarkably after surgery and declined to normal level after two-course chemotherapy.No obvious neurological deficit occurred except for short-term memory difficulty which gradually recovered within two weeks.Soon after the second course chemotherapy the patient was currently asymptomatic and returned to school.Conclusions:(1)To ensure definitive diagnosis and proper therapecutic protocols benefit from grasping clinical features of mixed germ cell tumor.(2)Overall preoperative investigation including serum tumor marker level is as critical as neurological imaging examination.(3)Surgical excision is confirmed to be the key modality of treatment.With the regarding of mixed germ cell tumor,never highlight total resection too much.(4)Postoperative adjuvant chemotherapy is recommended as further intensive treatment to improve the prognosis of mix germ cell tumor. | Yapeng Zhao Hongyu Duan Qinghui Zhang Bingxin Shi Hui Liang Yuqi Zhang | 2016 | Translational Neuroscience and Clinics2016，2，1： | 0 |
| 19 | An Improved Gorilla Troops Optimizer Based on Lens Opposition-Based Learning and Adaptive β-Hill Climbing for Global Optimization显示文摘Gorilla troops optimizer(GTO)is a newly developed meta-heuristic algorithm,which is inspired by the collective lifestyle and social intelligence of gorillas.Similar to othermetaheuristics,the convergence accuracy and stability of GTOwill deterioratewhen the optimization problems to be solved becomemore complex and flexible.To overcome these defects and achieve better performance,this paper proposes an improved gorilla troops optimizer(IGTO).First,Circle chaotic mapping is introduced to initialize the positions of gorillas,which facilitates the population diversity and establishes a good foundation for global search.Then,in order to avoid getting trapped in the local optimum,the lens opposition-based learning mechanism is adopted to expand the search ranges.Besides,a novel local search-based algorithm,namely adaptiveβ-hill climbing,is amalgamated with GTO to increase the final solution precision.Attributed to three improvements,the exploration and exploitation capabilities of the basic GTOare greatly enhanced.The performance of the proposed algorithm is comprehensively evaluated and analyzed on 19 classical benchmark functions.The numerical and statistical results demonstrate that IGTO can provide better solution quality,local optimumavoidance,and robustness compared with the basic GTOand five other wellknown algorithms.Moreover,the applicability of IGTOis further proved through resolving four engineering design problems and training multilayer perceptron.The experimental results suggest that IGTO exhibits remarkable competitive performance and promising prospects in real-world tasks. | Yaning Xiao Xue Sun Yanling Guo Sanping Li Yapeng Zhang Yangwei Wang | 2022 | Computer Modeling in Engineering & Sciences2022，，5： | 0 |
| 20 | Nitrogen doped porous carbon-based bifunctional oxygen electrocatalyst with controllable phosphorus content for zinc-air battery显示文摘The controllable construction of non-noble metal based bifunctional catalysts with high activities towards oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)is of great significance,but remains a challenge.Herein,we reported an effective method to synthesize cobalt-nitrogen doped mesoporous carbon-based bifunctional oxygen electrocatalyst with controllable phosphorus content(Co-N-P_(X)-MC,X=0.5,1.0,1.5,2.0).The mesoporous carbon substrate endowed the asprepared samples with more exposed active surface(236.50 m^(2)·g^(−1))and the most appropriate doping ratio of phosphorus had been investigated to be 1.5(Co-N-P1.5-MC).For ORR,Co-N-P1.5-MC exhibited excellent catalytic activity with more positive onset potential(1.01 V)and half-wave potential(0.84 V)than the other samples.For OER,Co-N-P1.5-MC also showed a low overpotential of 415 mV.Combining experimental results and density-functional theory(DFT)calculations,the outstanding bifunctional catalytic performance of Co-N-P1.5-MC was due to the synergistic cooperation between the P and N dopants,which could reduce the reaction barriers and was favorable for ORR and OER.Moreover,the Zn-air battery using Co-N-P1.5-MC as the cathode showed remarkable battery performance with high stability(could operate stably for over 160 h at 10 mA·cm^(−2))and maximum power density(119 mW·cm^(−2)),demonstrating its potential for practical applications.This work could provide significant enlightenment towards the design and construction of bifunctional oxygen electrocatalyst for next-generation electrochemical devices. | Shichang Cai Zihan Meng Gaojie Li Yu An Yapeng Cheng Erjun Kan Bo Ouyang Haining Zhang Haolin Tang | 2023 | Nano Research2023，16，4： | 0 |
