| 1 | Friction of low-dimensional nanomaterial systems显示文摘When material dimensions are reduced to the nanoscale,exceptional physical mechanics properties can be obtained that differ significantly from the corresponding bulk materials.Here we review the physical mechanics of the friction of low‐dimensional nanomaterials,including zero‐dimensional nanoparticles,one‐dimensional multiwalled nanotubes and nanowires,and two‐dimensional nanomaterials-such as graphene,hexagonal boron nitride(h‐BN),and transition‐metal dichalcogenides-as well as topological insulators.Nanoparticles between solid surfaces can serve as rolling and sliding lubrication,while the interlayer friction of multiwalled nanotubes can be ultralow or significantly high and sensitive to interwall spacing and chirality matching,as well as the tube materials.The interwall friction can be several orders of magnitude higher in binary polarized h‐BN tubes than in carbon nanotubes mainly because of wall buckling.Furthermore,current extensive studies on two‐dimensional nanomaterials are comprehensively reviewed herein.In contrast to their bulk materials that serve as traditional dry lubricants(e.g.,graphite,bulk h‐BN,and MoS_(2)),large‐area high‐quality monolayered two‐dimensional nanomaterials can serve as single‐atom‐thick coatings that minimize friction and wear.In addition,by appropriately tuning the surface properties,these materials have shown great promise for creating energy‐efficient self‐powered electro‐opto‐magneto‐mechanical nanosystems.State‐of‐the‐art experimental and theoretical methods to characterize friction in nanomaterials are also introduced. | Wanlin GUO Jun YIN Hu QIU Yufeng GUO Hongrong WU Minmin XUE | 2014 | Friction2014，2，3： | 15 |
| 2 | Recent research progresses in ether-and ester-based electrolytes for sodium-ion batteries显示文摘Owing to the natural abundance and low cost of sodium resources,sodium-ion batteries(SIBs)have drawn considerable attention for state-of-the-art power storage devices over the last few years.To enable advanced SIBs with a brighter future,great effort has been made,not only through optimizing the electrode materials,but also with rationally designing various electrolyte systems.Among the available electrolyte systems,organic electrolytes,especially those based on esters as well as ethers,are the most promising ones for practical application in the foreseeable future,due to their numerous inherent advantages.This review is concerned with the recent research progresses on organic electrolytes for SIBs,focusing on etherbased and ester-based ones. | Zeheng Lin Qingbing Xia Wanlin Wang Weishan Li Shulei Chou | 2019 | InfoMat2019，1，3： | 12 |
| 3 | Low-complexity 2D coherently distributed sources decoupled DOAs estimation method显示文摘The existing directions-of-arrival(DOAs) estimation methods for two-dimensional(2D) coherently distributed sources need one-or two-dimensional search,and the computational complexities of them are high. In addition,most of them are designed for special angular signal distribution functions. As a result,their performances will degenerate when deal with different sources with different angular signal distribution functions or unknown angular signal distribution functions. In this paper,a low-complexity decoupled DOAs estimation method without searching using two parallel uniform linear arrays(ULAs) is proposed for coherently distributed sources,as well as a novel parameter matching method. It can resolve the problems mentioned above efficiently. Simulation results validate the effectiveness of our approach. | GUO XianSheng WAN Qun YANG WanLin LEI XueMei | 2009 | Science in China(Series F)2009，52，5： | 12 |
| 4 | Molten salts-modified MgO-based adsorbents for intermediate-temperature CO_2 capture: A review显示文摘Carbon dioxide(CO2) capture using magnesium oxide(MgO)-based adsorbents at intermediate temperatures has been regarded as a very prospective technology for their relatively high adsorption capacity,low cost, and wide availability. During the past few years, great effort has been devoted to the fabrication of molten salts-modified MgO-based adsorbents. The extraordinary progress achieved by coating with molten salts greatly promotes the CO_2 capture capacity of MgO-based adsorbents. Therefore, we feel it necessary to deliver a timely review on this type of CO_2 capturing materials, which will benefit the researchers working in both academic and industrial areas. In this work, we classified the molten saltsmodified MgO adsorbents into four categories:(1) homogenous molten salt-modified MgO adsorbents,(2) molten salt-modified double salts-based MgO adsorbents,(3) mixed molten salts-modified MgO adsorbents, and(4) molten salts-modified MgO-based mixed oxides adsorbents. This contribution critically reviews the recent developments in the synthetic method, adsorption capacity, reaction kinetics, promotion mechanism, operational conditions and regenerability of the molten salts-modified MgO CO_2 adsorbents. The challenges and prospects in this promising field of molten salts-modified MgO CO_2 adsorbents in real applications are also briefly mentioned. | Wanlin Gao Tuantuan Zhou Yanshan Gao Benoit Louis Dermot O'Hare Qiang Wang | 2017 | Journal of Energy Chemistry2017，26，5： | 12 |
| 5 | Preparation of modified SiO_2 colloidal spheres with succinic acid and the assembly of colloidal crystals显示文摘SiO2 colloidal spheres were synthesized by St-ber method. In order to enhance surface charge of the SiO2 spheres, they were modified with succinic acid. Scanning electron microscope (SEM) shows that the average size of modified SiO2 spheres is 473 nm, and its distribution standard deviation is less than 5%; Fourier-transform infrared spectra (FT-IR) and X-ray photoelectron spectrometer (XPS) results indicate that one end of succinic acid is chemically bonded to the SiO2 spheres through esterification; Zeta potential of the modified SiO2 spheres in water solution is improved from -53.72 to -67.46 mV, and surface charge density of the modified SiO2 spheres is enhanced from 0.19 to 0.94 μC/cm2. SiO2 colloidal crystal was fabricated from aqueous colloidal solution by the vertical deposition method at 40℃ and 60% relative humidity. SEM images show that the sample of SiO2 colloidal crystal is face-centered cubic (fcc) structure with its (111) planes parallel to the substrate. Transmission measurement shows the existence of photonic band gap at 1047 nm. | FANG Jun WANG XiuFeng WANG LieSong CHENG Bing WU Yuan-Ting ZHU WanLin | 2007 | Chinese Science Bulletin2007，52，4： | 9 |
| 6 | Shaking table experimental study of recycled concrete frame-shear wall structures显示文摘In this study, four 1/5 scaled shaking table tests were conducted to investigate the seismic performance of recycled concrete frame-shear wall structures with different recycled aggregates replacement rates and concealed bracing detail. The four tested structures included one normal concrete model, one recycled coarse aggregate concrete model, and two recycled coarse and fi ne aggregate concrete models with or without concealed bracings inside the shear walls. The dynamic characteristics, dynamic response and failure mode of each model were compared and analyzed. Finite element models were also developed and nonlinear time-history response analysis was conducted. The test and analysis results show that the seismic performance of the recycled coarse aggregate concrete frame-shear wall structure is slightly worse than the normal concrete structure. The seismic resistance capacity of the recycled concrete frame-shear wall structure can be greatly improved by setting up concealed bracings inside the walls. With appropriate design, the recycled coarse aggregate concrete frame-shear wall structure and recycled concrete structure with concealed bracings inside the walls can be applied in buildings. | Zhang Jianwei Cao Wanlin Meng Shaobin Yu Cheng Dong Hongying | 2014 | Earthquake Engineering and Engineering Vibration2014，13，2： | 8 |
| 7 | Uncoupling neurotrophic function from nociception of nerve growth factor: what can be learned from a rare human disease?显示文摘Nerve growth factor(NGF) is a powerful trophic factor that provides essential support for the survival and differentiation of sympathetic and sensory neurons during development. However, NGF also activates nociceptors contributing significantly to inflammatory pain and neuropathic pain after tissue injury. As such anti-NGF based therapies represent a promising strategy for pain management. Because of dose-dependent serious side effects such as back pain, injection site hyperalgesia, clinical trials of using NGF to treat various disorders such as diabetic neuropathies, chemotherapy-induced and human immunodeficiency virus-associated peripheral neuropathies were all discontinued. Thus far, worldwide clinical applications of NGF in treating patients are very limited except in China. Hereditary sensory autonomic neuropathy type V(HSAN V) is an extremely rare disease. Genetic analyses have revealed that HSAN V is associated with autosomal recessive mutations in NGF. One of the mutations occurred at the 100^(th) position of mature NGF resulting in a change of residue from arginine to tryptophan(R100W). Although those HSAN V patients associated with the NGF^(R100W) mutation suffer from severe loss of deep pain, bone fractures and joint destruction, interestingly patients with the NGF^(R100W) mutation do not show apparent cognitive deficits, suggesting important trophic support function is preserved. We believe that NGF^(R100W) provides an ideal tool to uncouple the two important functions of NGF: trophic versus nociceptive. Studies from investigators including ourselves have indeed confirmed in animal testing that the NGF^(R100W) no longer induced pain. More importantly, the trophic function seemed to be largely preserved in NGF harboring the R100W mutation. On the mechanistic level, we found that the NGF^(R100W) mutation was capable of binding to and signaling through the tyrosine receptor kinase A receptor. But its ability to bind to and activate the 75 kDa neurotrophic factor was significantly diminished. The significance of these findings is at least two folds: 1) the NGF^(R100W) mutation can be used as an alternative to the wildtype NGF to treat human conditions without eliciting pain; and 2) the 75 kDa neurotrophic factor may serve as a novel target for pain management. We will discuss all the details in this mini-review. | Kijung Sung Wanlin Yang Chengbiao Wu | 2019 | Neural Regeneration Research2019，14，4： | 5 |
| 8 | Absolute calibration of HY-2A and Jason-2 altimeters for sea surface height using GPS buoy in Qinglan, China显示文摘GPS buoy methodology is one of the main calibration methodologies for altimeter sea surface height calibration. This study introduces the results of the Qinglan calibration campaign for the HY-2A and Jason-2 altimeters. It took place in two time slices;one was from August to September 2014, and the other was in July 2015. One GPS buoy and two GPS reference stations were used in this campaign. The GPS data were processed using the real-time kinematic (RTK) technique. The fi nal error budget estimate when measuring the sea surface height (SSH) with a GPS buoy was better than 3.5 cm. Using the GPS buoy, the altimeter bias estimate was about -2.3 cm for the Jason-2 Geophysical Data Record (GDR) Version ‘D' and from -53.5 cm to -75.6 cm for the HY-2A Interim Geophysical Data Record (IGDR). The bias estimates for Jason-2 GDR-D are similar to the estimates from dedicated calibration sites such as the Harvest Platform, the Crete Site and the Bass Strait site. The bias estimates for HY-2A IGDR agree well with the results from the Crete calibration site. The results for the HY-2A altimeter bias estimated by the GPS buoy were verifi ed by cross-calibration, and they agreed well with the results from the global analysis method. | CHEN Chuntao ZHU Jianhua ZHAI Wanlin YAN Longhao ZHAO Yili HUANG Xiaoqi YANG Weiwei | 2019 | Journal of Oceanology and Limnology2019，37，5： | 5 |

| 11 | Coupling of Hierarchical Al_(2)O_(3)/TiO_(2) Nanofibers into 3D Photothermal Aerogels Toward Simultaneous Water Evaporation and Purification显示文摘Serious freshwater shortage and environmental pollution boost the rapid development of solar-driven water production.Although improved evaporation rate has achieved in recent years,undesirable impurity(e.g.,pollutant components)can also be inevitably evaporated and collected as impurity in produced freshwater.This work reports new ultra-light three-dimensional(3D)aerogels assembled by hierarchical Al_(2)O_(3)/TiO_(2) nanofibers and reduced graphene oxide(RGO)for excit-ing synchronized solar-driven evaporation and water purification.Hydrophilic Al_(2)O_(3)/TiO_(2) fibrous channels linked up the graphene hot-spots and water body for sufficient water supply and bulk water insulation.Meanwhile,featured with thermal insulation effect,the Al_(2)O_(3)/TiO_(2) nanofibers effectively locked the converted heat with less energy loss from sunlight.The introducing of Al_(2)O_(3)/TiO_(2) nanofibers into RGO aerogel led to the effective interfacial evaporation for a more rapid water evaporation rate(2.19 kg·m−2·h−1,normalized to evaporation area including both top and side surface),which was 36%higher than that of pristine RGO aerogel.Moreover,simultaneous with the strong steam generation,Al_(2)O_(3)/TiO_(2) nanofibers in situ removed the pollutants within steam by photodegradation,achieving polluted wastewater purification with high con-taminant removal ratio of 91.3%.Our work on coupling Al_(2)O_(3)/TiO_(2) nanofibers into photothermal aerogel provides attractive solutions for the challenges of clean water scarcity and serious environmental pollution. | Xiangyu Meng Wanlin Xu Zhihui Li Jianhui Yang Jingwu Zhao Xixi Zou Yueming Sun Yunqian Dai | 2020 | Advanced Fiber Materials2020，2，2： | 4 |
| 12 | Experimental and analytical study on seismic behavior of steel-concrete multienergy dissipation composite shear walls显示文摘In this paper, a steel-concrete multi-energy dissipation composite shear wall, comprised of steel-reinforced concrete(SRC) columns, steel plate(SP) deep beams, a concrete wall and energy dissipation strips, is proposed. In order to study the multi-energy dissipation behavior and restorability after an earthquake, two stages of low cyclic loading tests were carried out on ten test specimens. In the first stage, test on five specimens with different number of SP deep beams was carried out, and the test lasted until the displacement drift reached 2%. In the second stage, thin SPs were welded to both sides of the five specimens tested in the first stage, and the same test was carried out on the repaired specimens(designated as new specimens). The load-bearing capacity, stiffness, ductility, hysteretic behavior and failure characteristics were analyzed for both stages and the results are discussed herein. Extrapolating from these results, strength calculation models and formulas are proposed herein and simulations using ABAQUS carried out; they show good agreement with the test results. The study demonstrates that SRC columns, SP deep beams, concrete wall and energy dissipation strips cooperate well and play an important role in energy dissipation. In addition, this study shows that the shear wall has good recoverability after an earthquake, and that the welding of thin SP's to repair a deformed wall is a practicable technique. | Dong Hongying Cao Wanlin Wu Haipeng Qiao Qiyun Yu Chuanpeng | 2015 | Earthquake Engineering and Engineering Vibration2015，14，1： | 4 |
| 13 | Variant rs2237892 of KCNQ1 Is Potentially Associated with Hypertension and Macrovascular Complications in Type 2 Diabetes Mellitus in A Chinese Han Population显示文摘KCNQ1 has been identified as a susceptibility gene of type 2 diabetes mellitus(T2DM) in Asian populations through genome-wide association studies. However, studies on the association between gene polymorphism of KCNQ1 and T2 DM complications remain unclear. To further analyze the association between different alleles at the single nucleotide polymorphism(SNP) rs2237892 within KCNQ1 and TD2 M and its complications, we conducted a case-control study in a Chinese Han population. The C allele of rs2237892 variant contributed to susceptibility to T2DM(odds ratio [OR], 1.45; 95% confidence interval [CI], 1.20–1.75). Genotypes CT(OR, 1.97; 95% CI,1.24–3.15) and CC(OR, 2.49; 95% CI, 1.57–3.95) were associated with an increased risk of T2 DM. Multivariate regression analysis was performed with adjustment of age, gender, and body mass index. We found that systolic blood pressure(P = 0.015), prevalence of hypertension(P = 0.037), and risk of macrovascular disease(OR, 2.10; CI, 1.00–4.45) were significantly higher in subjects with the CC genotype than in the combined population with genotype either CT | Wanlin Zhang Hailing Wang Xiaomin Guan Qing Niu Wei Li | 2015 | Genomics, Proteomics & Bioinformatics2015，13，6： | 4 |
| 14 | Progress,problems and prospects for standardization of greenhouse-related technologies显示文摘In recent years,the scale of greenhouse grows rapidly and steadily in China,which promotes the development of greenhouse technology and the demand for standardized technology.However,the standardization process of greenhouse industry in China has been facing with the problem of unbalanced development with the practical standard system for many years.To solve these problems,the most characteristic greenhouse designs used in China contributing to this work are presented in detail.And the development of standard system and the standardization efforts of them are summarized and analyzed in relationship to the data presented in this paper.In this way the origin of greenhouse standard system in China and context of the system development and standardization of greenhouse structure are clarified.It was also found that the development and iterative update of greenhouse standard system are under the influences of enterprises which as the participation of standard constitutors were proved to play an important role in promoting the standardization development of greenhouse.The outcome of this work may be utilized to perfect the greenhouse standardization system and improve the greenhouse standardization efficiency that dominate the facility agriculture in China. | Yanzhao Ren Minjuan Wang Iftikhar Ahmed Saeeda Xuerui Chen Wanlin Gao | 2018 | International Journal of Agricultural and Biological Engineering2018，11，1： | 4 |
| 15 | Research on seismic performance of shear walls with concrete filled steel tube columns and concealed steel trusses显示文摘In order to further improve the seismic performance of RC shear walls, a new composite shear wall with concrete filled steel tube (CFT) columns and concealed steel trusses is proposed. This new shear wall is a double composite shear wall; the first composite being the use of three different force systems, CFT, steel truss and shear wall, and the second the use of two different materials, steel and concrete. Three 1/5 scaled experimental specimens: a traditional RC shear wall, a shear wall with CFT columns, and a shear wall with CFT columns and concealed steel trusses, were tested under cyclic loading and the seismic performance indices of the shear walls were comparatively analyzed. Based on the data from these experiments, a thorough elastic-plastic finite element analysis and parametric analysis of the new shear walls were carried out using ABAQUS software. The finite element results of deformation, stress distribution, and the evolution of cracks in each phase were compared with the experimental results and showed good agreement. A mechanical model was also established for calculating the load-carrying capacity of the new composite shear walls. The results show that this new type of shear wall has improved seismic performance over the other two types of shear walls tested. | Cao Wanlin Zhang Jianwei Dong Hongying Wang Min | 2011 | Earthquake Engineering and Engineering Vibration2011，10，4： | 3 |
| 16 | Spray drift characteristics test of unmanned aerial vehicle spray unit under wind tunnel conditions显示文摘Since the 2010s,unmanned aerial vehicle(UAV)sprayer was applied more and more widely for low-volume aerial pesticides spraying operations in China.However,droplets from the UAV sprayer have a higher drift risk due to more fine droplets sprayed and a higher flight height than ground sprayers.Study on UAV spray drift has been a new hot spot within the field of pesticide application technology.Most of previous studies used direct field methods for spray drift,but the meteorological conditions in field were unstable and uncontrollable,and drift research under an actual operation state in wind tunnel has not been reported.Therefore,25 treatments of wind tunnel measurements and droplets spectrum tests of 10 models of nozzles were conducted to explore the influence factor on spray drift characteristics of UAV chemicals application in this study.A spray unit with a rotor of UAV was innovatively installed in wind tunnel,and the airstream from the wind tunnel was regarded as the relative moving natural wind to simulate the flight status.The airborne and the sediment spray drift was measured to study the effects of the nozzle type and size(flat fan,hollow cone and air-inclusion nozzles),flight speed,adjuvant(DRS-60,Y-20079,MF and G-611)and meteorological parameters(20°C&40%,20°C&80%,30°C&40%and 30°C&60%).The drift potential(DP)and the drift potential reduction percentage(DPRP)in vertical and horizontal directions were obtained for each test.Both nozzle type and size had an impact on the spray drift potential obviously by affecting the droplet size and the ratio of fine droplets,and the regression linear models between DPRPV/DPRPH and DV50,V75 were established(R2=0.934/0.925).Flight speed also had a significant effect on the spray drift characteristics,and reducing the flight speed could increase the DP effectively.Adding spray adjuvants could affect the DP under experimental meteorological parameters,and the anti-drift performance ranked in the order of DRS-60>MF>Y-20079>G-611.Recommendations were proposed in order to reduce the spray drift for UAV sprayer’s operation.These findings can contribute to provide guidelines and technical support for the wind tunnel spray drift tests of UAV and the field operation regulation of unmanned aerial PPP application. | Changling Wang Aijun Zeng Xiongkui He Jianli Song Andreas Herbst Wanlin Gao | 2020 | International Journal of Agricultural and Biological Engineering2020，13，3： | 3 |
| 17 | Designing high-strength titanium alloy using pseudo-spinodal mechanism through diffusion multiple experiment and CALPHAD calculation显示文摘This study used the pseudo-spinodal mechanism to obtain the ultrafineαphase for designing highstrength titanium alloy.Diffusion multiple experiments were designed to find the composition range of TM-x Mo-y V alloy(TM:Ti-4.5 Al-2 Cr-2.5 Nb-2 Zr-1 Sn)for obtaining ultrafineαphase.CALPHAD results confirm that when the alloy composition is located near the intersection of theαandβphase free energy curves,the alloy will undergo pseudo-spinodal transformation and obtain the ultrafineαphase.The designed TM-6 Mo-3 V alloy has a yield strength of 1411 MPa and an elongation of 6.5%.The strength of the alloy depends on the thickness,fraction of theαphase and the solid solution strengthening effect of the alloying elements.The deformation mechanism of the alloy is the dislocation slip of theαandβphases and the twin deformation of theαphase.The large number ofα/βinterfaces produced by the fineαphase is the main reason for limiting the ductility of the alloy.The use of the pseudo-spinodal mechanism combined with diffusion multiple experiments and CALPHAD is an effective method for designing high-strength titanium alloys. | Di Wu Libin Liu Lijun Zeng Wenguang Zhu Wanlin Wang Xiaoyong Zhang Junfeng Hou Baoliang Liu Jiafeng Lei Kechao Zhou | 2021 | Journal of Materials Science & Technology2021，，15： | 3 |
| 18 | FLEXURAL WAVE DISPERSION IN MULTI-WALLED CARBON NANOTUBES CONVEYING FLUIDS显示文摘Motivated by the great potential of carbon nanotubes for developing nanofluidic devices,this paper presents a nonlocal elastic,Timoshenko multi-beam model with the second order of strain gradient taken into consideration and derives the corresponding dispersion relation of flexural wave in multi-walled carbon nanotubes conveying fluids.The study shows that the moving flow reduces the phase velocity of flexural wave of the lowest branch in carbon nanotubes.The phase velocity of flexural wave of the lowest branch decreases with an increase of flow velocity.However,the effects of flow velocity on the other branches of the wave dispersion are not obvious.The effect of microstructure characterized by nonlocal elasticity on the dispersion of flexural wave becomes more and more remarkable with an increase in wave number. | Lifeng Wang Wanlin Guo Haiyan Hu | 2009 | Acta Mechanica Solida Sinica2009，22，6： | 3 |
| 19 | Materials for evaporation-driven hydrovoltaic technology显示文摘Water constitutes the largest energy carrier on earth,absorbing more than 70%of the solar energy received by the earth's surface,yet its low exploitation has been a constant concern.The hydrovoltaic effect is an emerging technology that generates electricity through the direct interaction between nanomaterials and water of various forms(raindrops,waves,flows,moisture,and natural evaporation).Especially,the evaporation-driven hydrovoltaic effect is a spontaneous and ubiquitous process that can directly convert thermal energy from the surrounding environment into electricity without the demand for additional mechanical work,which shows unique advantages compared with other hydrovoltaic effects.A variety of nanostructured materials have been steadily developed for evaporation-driven hydrovoltaic devices(EHDs)in recent years.However,there has been a lack of a clear specification on the selection and design of materials for improving device performance.Herein,we first analyze the mechanisms of EHDs followed by a summarization of the recent advances in materials,including carbon materials,biomass-based materials,metal oxides,composite materials,and others.We then discuss the strategies for improving the energy conversion efficiency and the output power in terms of structural design,surface modification,and interface treatment.Finally,we provide an outlook on the potential applications of electricity generation,sensors,and desalination technology,as well as the challenges and prospects for the development of this emerging technology in the future. | Chunxiao Zheng Weicun Chu Sunmiao Fang Jin Tan Xiaofan Wang Wanlin Guo | 2022 | Interdisciplinary Materials2022，1，4： | 3 |
| 20 | 3D carbon network supported porous SiOC ceramics with enhanced microwave absorption properties显示文摘Porous SiOC ceramic was successfully prepared by pyrolysis of dimethylsilicone oil,silane coupling agent and melamine foam.The microwave absorbing properties of porous SiOC were studied for the first time.At the matching layer thickness of 3.0 mm,the paraffin-based composite with porous SiOC displays a minimum reflection coefficient(RC)of-39.13 d B(11.76 GHz)and an effective absorption bandwidth(EAB)of 4.64 GHz which are much larger than that of paraffin-based composite with ordinary SiOC.It is found that the porous structure of SiOC is crucial to achieve its high microwave absorption performance by improving both the polarization loss and conduction loss.The enhanced polarization loss is originated from the dipole polarization and interfacial polarization,while the improvement of conduction loss is attributed to the carbon skeleton of porous SiOC.These results indicate that porous SiOC ceramic is a promising candidate for high-performance ceramic-based microwave absorbing materials. | Chen Chen Sifan Zeng Xiaochun Han Yongqiang Tan Wanlin Feng Huahai Shen Shuming Peng Haibin Zhang | 2020 | Journal of Materials Science & Technology2020，54，19： | 3 |
