| 1 | Generation of new glutinous rice by CRISPR/Cas9-targeted mutagenesis of the Waxy gene in elite rice varieties显示文摘In rice, amylose content(AC) is controlled by a single dominant Waxy gene. We used Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/CRISPR-associated 9(Cas_9) to introduce a loss-of-function mutation into the Waxy gene in two widely cultivated elite japonica varieties. Our results show that mutations in the Waxy gene reduce AC and convert the rice into glutinous ones without affecting other desirable agronomic traits, offering an effective and easy strategy to improve glutinosity in elite varieties. Importantly, we successfully removed the transgenes from the progeny. Our study provides an example of generating improved crops with potential for commercialization, by editing a gene of interest directly in elite crop varieties. | Jinshan Zhang Hui Zhang Jose Ramón Botella Jian-Kang Zhu | 2018 | Journal of Integrative Plant Biology2018，60，5： | 49 |
| 2 | Perspectives on the Application of Genome-Editing Technologies in Crop Breeding显示文摘Most conventional and modern crop-improvement methods exploit natural or artificially induced genetic variations and require laborious characterization of the progenies of multiple generations derived from time-consuming genetic crosses.Genome-editing systems,in contrast,provide the means to rapidly modify genomes in a precise and predictable way,making it possible to introduce improvements directly into elite varieties.Here,we describe the range of applications available to agricultural researchers using existing genome-editing tools.In addition to providing examples of genome-editing applications in crop breeding,we discuss the technical and social challenges faced by breeders using genome-editing tools for crop improvement. | Kai Hua Jinshan Zhang Jose Ramon Botella Changle Ma Fanjiang Kong Baohui Liu Jian-Kang Zhu | 2019 | Molecular Plant2019，12，8： | 19 |
| 3 | Corrosion Behavior of Mg-Zn-Y Alloy with Long-period Stacking Ordered Structures显示文摘Mg-Zn-Y alloys with long-period stacking ordered structures were prepared by an ingot casting method. The corrosion performance of Mg-Zn-Y alloys was studied by combining gas-collecting test, immersion test and electrochemical measurements in order to determine the corrosion rate and mechanism of the alloys. The results showed that the volume fraction of Mg(12)YZn phase increased and the shape of the Mg(12)YZn phase changed from discontinuous to continuous net-like with increasing Zn and Y content. The corrosion rate of the alloys greatly depended on the distribution and volume fraction of the Mg(12)YZn phase. Corrosion products appeared at the junction of Mg phase and Mg(12)YZn phase, indicating that the Mg(12)YZn phase accelerated galvanic corrosion of Mg matrix. Mg(97)Zn1Y2 alloy shows the lowest corrosion rate due to the continuous distribution of Mg(12)YZn phase. | Jinshan Zhang Jidong Xu Weili Cheng Changjiu Chen Jingjing Kang | 2012 | Journal of Materials Science & Technology2012，28，12： | 17 |
| 4 | Effects of applying lactic acid bacteria to the fermentation on a mixture of corn steep liquor and air-dried rice straw显示文摘This study was to determine the fermentation quality of a mixture of corn steep liquor(CSL)(178 g/kg wet basis) and air-dried rice straw(356 g/kg wet basis) after being treated with inoculants of different types of lactic acid bacteria(LAB). The treatments included the addition of no LAB additive(control),which was deionized water; homo-fermentative LAB alone(^(ho)LAB), which was Lactobacillus plantarum alone), and a mixture of homo-fermentative and hetero-fermentative LAB(^(he+ho)LAB), which were L. plantarum, Lactobacillus casei, and Lactobacillus buchneri. The results showed that the inoculation of the mixture of CSL and air-dried rice straw with ^(he+ho)LAB significantly increased the concentration of acetic acid and lactic acid compared with the control(P < 0.05). The addition of ^(he+ho)LAB effectively inhibited the growth of yeast in the silage. The concentration of total lactic acid bacteria in the ^(he+ho)LAB-treated silage was significant higher than those obtained in other groups(P < 0.05). The duration of the aerobic stability of the silages increased from 56 h to >372 h. The control group was the first to spoil, whereas the silage treated with ^(he+ho)LAB remained stable throughout the 372 h period of monitoring. The results demonstrated that the ^(he+ho)LAB could effectively improve the fermentation quality and aerobic stability of the silage. | Xinxin Li Wenbin Xu Jinshan Yang Hongbo Zhao Chunfang Pan Xue Ding Yonggen Zhang | 2016 | Animal Nutrition2016，，3： | 17 |
| 5 | Microstructural evolution and FCC twinning behavior during hot deformation of high temperature titanium alloy Ti65显示文摘Although the development of titanium alloys with working temperatures above 600?C faces enormous difficulties and challenges,the related research has not stopped.In the present work,detailed analyses on microstructure evolution and hot deformation behavior of a new temperature resistant 650?C titanium alloy Ti65 were investigated from micrometer scale to nanometer scale.The results revealed that lamellarαgrains gradually fragmentized and spheroidized during theα+βphase region compression and the orientation of the c-axis ofαgrains gradually aligned to radial directions,forming two high Schmid factors(SFs)value texture eventually with the increase of strain to 0.7.Moreover,there were some strengthening characters in theα+βphase region such as lenticularαsand nano silicide(TiZr)6 Si3.In theβphase region,fine equiaxed dynamic recrystallized(DRX)βgrains were formed.Besides,the variant selection ofαm′artensite followed Burgers orientation relationship during the compression process.The main deformation mechanisms of theα+βphase region were dislocation slip and orientation dependent spheroidization.Whereas,the deformation process in theβphase region was controlled byβgrain DRX.Interestingly,many nano scale FCC twins were generated at the interface ofαl′ath during deforming in theβphase region,which was firstly observed in Ti65 alloy. | Zhixin Zhang Jiangkun Fan Bin Tang Hongchao Kou Jian Wang Xin Wang Shiying Wang Qingjiang Wang Zhiyong Chen Jinshan Li | 2020 | Journal of Materials Science & Technology2020，47，14： | 10 |

| 7 | Research on KOH/La-Ba-Al_2O_3 catalysts for biodiesel production via transesterification from microalgae oil显示文摘Alumina supports modified by lanthanum(La)and barium(Ba)were prepared by peptization.Catalysts with different KOH contents supported on modified alumina were prepared by impregnation method.Various techniques,including N2 adsorption-desorption(Brunauer-Emmet-Teller method,BET),X-ray diffraction(XRD),scanning electron microscopy(SEM),and fourier transform infrared absorption spectroscopy(FT-IR). Catalytic activity for microalgae oil conversion to methyl ester via transesterification was evaluated and analyzed by GC-MS and GC.BET results showed that the support possessed high specific surface area,suitable pore volume and pore size distribution.Activity results indicated that the catalyst with 25 wt%KOH showed the best activity for microalgae oil conversion.XRD and SEM results revealed that Al-O-K compound was the active phase for microalgae oil conversion.The agglomeration and changing of pore structure should be the main reasons for the catalyst deactivation when KOH content was higher than 30 wt%. | Xiaoyu Zhang Qing Ma Bibo Cheng Jun Wang Jinshan Li Fude Nie | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 7 |
| 8 | Orientation dependent behavior of tensile-creep deformation of hot rolled Ti65 titanium alloy sheet显示文摘The mill products like sheet always have one or more severe textures inevitably,and its effect on mechanical properties is not a negligible issue.The orientation dependent tensile-creep behavior induced by rolling texture of Ti65 titanium alloy sheet has been systematically investigated at 650℃.There are some anisotropic characteristics between TD and RD of Ti65 sheet.The UTS and TYS of TD are higher than RD at 650℃.Besides,the creep endurance time of TD(172.6–174.5 h)is about three times longer than RD(55.6–65.1 h)at 650℃and 240 MPa.Moreover,the grains are inclined to form Texture III■after creep along with TD,but to form Texture I■after creep along with RD.Finally,the crack initiation site is different during creep in TD and RD.The reason for anisotropic properties of tensile and creep has been summarized in two aspects:(i)the change of the SFs(Schmid factors)value between TD and RD;(ii)the difference of creep mechanism between TD(grain boundary sliding)and RD(dislocation slip).Anisotropy of Ti65 sheet should be fully considered to increase structural efficiency in the engineering design and application. | Zhixin Zhang Jiangkun Fan Ruifeng Li Hongchao Kou Zhiyong Chen Qingjiang Wang Hailong Zhang Jian Wang Qi Gao Jinshan Li | 2021 | Journal of Materials Science & Technology2021，，16： | 7 |
| 9 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (https://blossom.ffr.mtu.edu/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018，11，11： | 7 |
| 10 | Natural selection maintains the transcribed LTR retrotransposons in Nosema bombycis显示文摘Eight intact LTR retrotransposons(Nbr1?Nbr8)have been previously characterized from the genome of Nosema bombycis,a eu-karyotic parasite with a compact and reduced genome.Here we describe six novel transcribed Nbr elements(Nbr9?Nbr14)identified through either cDNA library or RT-PCR.Like previously determined ones,all of them belong to the Ty3/Gypsy superfamily.Retrotransposon diversity and incomplete domains with insertions(Nbr12),deletions(Nbr11)and in-frame stop codons in coding regions(Nbr9)were detected,suggesting that both defective and loss events of LTR retrotransposon have happened in N.bombycis genome.Analysis of selection showed that strong purifying selection acts on all elements except Nbr11.This implies that selective pressure keeps both these Nbrs and their functions in genome.Interestingly,Nbr11 is under positive selection and some positively selected codons were identified,indicating that new functionality might have evolved in the Nbr11 retrotransposon.Unlike other transposable elements,Nbr11 has integrated into a conserved syntenic block and probably resulted in the inversion of both flanking regions.This demonstrates that transposable element is an important factor for the reshuffling and evolution of their host genomes,and may be maintained under natural selection. | Heng Xiang Guoqing Pan Ruizhi Zhang Jinshan Xu Tian Li Wenle Li Zeyang Zhou Zhonghuai Xiang | 2010 | Journal of Genetics and Genomics2010，37，5： | 7 |
| 11 | Disruption of MIR396e and MIR396f improves rice yield under nitrogen-deficient conditions显示文摘The microRNA miR396 directly represses GROWTH-REGULATING FACTORs(OsGRFs)and has been implicated in regulating rice yield and in nitrogen assimilation.Overexpressing the miR396 targets OsGRF4 and OsGRF6 improves rice yield via increased grain size and panicle branching,respectively.Here,we used CRISPR/Cas9 to assess the function of miR396 genes in rice.Knockout of MIR396 ef(MIR396e and MIR396f),but not other isoforms,enhanced both grain size and panicle branching,resulting in increased grain yield.Importantly,under nitrogen-deficient conditions,mir396ef mutants showed an even higher relative increase in grain yield as well as elevated above-ground biomass.Furthermore,we identified OsGRF8 as a new target of miR396,in addition to the known targets OsGRF4 and OsGRF6.Disruption of the miR396-targeting site in OsGRF8 was sufficient to both enlarge grain size and elongate panicles.Our results suggest that rice-seed and panicle development are regulated by miR396ef-GRF4/6/8-GIF1/2/3 modules and that mi R396ef are promising targets of genome editing for breeding environmentally friendly rice varieties that require less nitrogen fertilization. | Jinshan Zhang Zhenyu Zhou Jinjuan Bai Xiaoping Tao Ling Wang Hui Zhang Jian-Kang Zhu | 2020 | National Science Review2020，7，1： | 7 |
| 12 | Rhizosphere and bulk soil enzyme activities in a Nothotsuga longibracteata forest in the Tianbaoyan National Nature Reserve,Fujian Province,China显示文摘The rhizosphere, distinct from bulk soil, is defined as the volume of soil around living roots and influenced by root activities. We investigated protease,invertase, cellulase, urease, and acid phosphatase activities in rhizosphere and bulk soils of six Nothotsuga longibracteata forest communities within Tianbaoyan National Nature Reserve, including N. longibracteata + either Phyllostachys pubescens, Schima superba, Rhododendron simiarum, Cunninghamia lanceolata, or Cyclobalanopsis glauca, and N. longibracteata pure forest. Rhizosphere soils possessed higher protease, invertase, cellulase, urease,and acid phosphatase activities than bulk soils. The highest invertase, urease, and acid phosphatase activities were observed in rhizosphere samples of N. longibracteata+ S.superba. Protease was highest in the N. longibracteata + R. simiarum rhizosphere, while cellulase was highest in the pure N. longibracteata forest rhizosphere.All samples exhibited obvious rhizosphere effects on enzyme activities with a significant linear correlation between acid phosphatase and cellulase activities(p \ 0.05) in rhizosphere soils and between protease and acid phosphatase activities(p \ 0.05) in bulk soils. A principal component analysis, correlating 13 soil chemical properties indices relevant to enzyme activities, showed that protease, invertase, acid phosphatase, total N, and cellulase were the most important variables impacting rhizosphere soil quality. | Shihong Xiao Huiming You Weibin You Jinshan Liu Changtang Cai Jianqin Wu Zhirong Ji Shihua Zhan Zhesen Hu Zhongrui Zhang Dongjin He | 2017 | Journal of Forestry Research2017，28，3： | 7 |
| 13 | Effect of different levels of corn steep liquor addition on fermentation characteristics and aerobic stability of fresh rice straw silage显示文摘The object of this study was to determine the proper mixing ratio of fresh rice straw to corn steep liquor(CSL) to obtain a high protein content silage feed. The following experimental silages were generated: the control(C1), composed of fresh rice straw without CSL additive, mixed with CSL in the ratios of 4:1(C4),3:1(C3) and 2:1(C2). Lactic acid bacteria(LAB) inoculant was applied at the rate of 50 mL/kg(fresh basis)of forage to achieve a final application rate of 1 x 10~6 cfu/g of fresh matter(FM). Duplicate silos for each treatment were opened after 0,3, 7,10,20,30,45 and 60 d for microbiological and chemical analysis. The results showed that the addition of CSL significantly increased crude protein(CP) contents, and decreased neutral detergent fiber(NDF) and acid detergent fiber(ADF) contents of treatments after 60 d of ensiling(P < 0.05). The lactic acid contents in C4 and C3 were significantly higher than that in C1(P <0.05). In summary, mixing fresh rice straw with CSL at addition levels of 4:1(C4) and 3:1(C3) can improve the fermentation quality and nutrient composition of fresh rice straw silage. However, a large proportion of CSL(C3) had a negative impact on the aerobic stability of fresh rice straw. | Xinxin Li Wenbin Xu Jinshan Yang Hongbo Zhao Hangshu Xin Yonggen Zhang | 2016 | Animal Nutrition2016，，4： | 6 |
| 14 | Microstructure and corrosion behavior of Mg-Zn-Y-Al alloys with long-period stacking ordered structures显示文摘Mg97−xZn1Y2Alx alloys with long-period stacking ordered(LPSO)structures were prepared by conventional casting method.The optical microscopy(OM),X-ray diffraction(XRD)and the scanning electron microscope(SEM)equipped with energy dispersive X-ray spectroscopy(EDS)were used to analyze the microstructure of the alloys with different compositions.Immersion test and electrochemical measurement were used to evaluate the corrosion behavior of the alloys at room temperature,and the corrosive medium is 3.5%NaCl aqueous solution.The results showed that,with the increasing aluminum(Al)addition,exceptα-Mg and LPSO phases,new phases also emerged on the grain boundaries.At the same time,the zigzag part of LPSO phases disappeared,and the boundaries between LPSO phases andα-Mg became smooth.Furthermore,the addition of Al to Mg-Zn-Y alloys could hinder the activity of cathodic hydrogen evolution reaction and improve the uniformity and compactness of the protective surface film,thus,enhanced the corrosion resistance of Mg-Zn-Y alloys. | Dan Wang Jinshan Zhang Jidong Xu Zilong Zhao Weili Cheng Chunxiang Xu | 2014 | Journal of Magnesium and Alloys2014，2，1： | 6 |
| 15 | Numerical study on effect of tidal phase on storm surge in the South Yellow Sea显示文摘Because of the special topography and large tidal range in the South Yellow Sea,the dynamic process of tide and storm surge is very complicated.The shallow water circulation model Advanced Circulation(ADCIRC)was used to simulate the storm surge process during typhoon Winnie,Prapiroon,and Damrey,which represents three types of tracks attacking the South Yellow Sea,which are,moving northward after landing,no landing but active in offshore areas,and landing straightly to the coastline.Numerical experiments were carried out to investigate the effects of tidal phase on the tide-surge interaction as well as storm surge.The results show that the peak surge caused by Winnie and Prapiroon occurs 2-5 h before the high tide and its occurring time relative to high tide has little change with tidal phase variations.On the contrary,under the action of Damrey,the occurring time of the peak surge relative to high tide varies with tidal phase.The variation of tide-surge interaction is about 0.06-0.37 m,and the amplitude variations of interaction are smooth when tidal phase changes for Typhoon Winnie and Prapiroon.While the interaction is about 0.07-0.69 m,and great differences exists among the stations for Typhoon Damrey.It can be concluded that the tide-surge interaction of the former is dominated by the tidal phase modulation,and the time of surge peak is insensitive to the tidal phase variation.While the interaction of the latter is dominated by storm surge modulation due to the water depth varying with tide,the time of surge peak is significantly affected by tidal phase.Therefore,influence of tidal phase on storm surge is related to typhoon tracks which may provide very useful information at the design stage of coastal protection systems. | ZHANG Weisheng TENG Ling ZHANG Jinshan XIONG Mengjie YIN Chengtuan | 2019 | Journal of Oceanology and Limnology2019，37，6： | 5 |
| 16 | Experimental Analysis of Shear Strength of Undisturbed Soil in Leucaena Forest in Jiangjia Ravine,Yunnan,China显示文摘Five leucaena trees of similar age were chosen in Jiangjia Ravine of Dongchuan,Yunnan Province,China,near which the soil samples were collected by digging profiles 2m in depth and 1m in width.In each section,soil samples at different depths were taken for direct shear experiments to determine the root amount and mechanical composition.It is found that the cohesion and internal friction angle of the undisturbed soil are related to the root amount,depth,clay content and breccias content.Cohesion correlates negatively with root content,a finding that differs from that of other researchers.In addition,internal friction angle correlates positively with all these factors. | JIAO Zhen | 2010 | Journal of Mountain Science2010，7，4： | 5 |
| 17 | Effect of Ce-rich rare earth on microstructure and mechanical properties of Mg-10Zn-5Al-0.1Sb magnesium alloy显示文摘To improve the comprehensive mechanical properties of Mg-10Zn-5Al-0.1Sb magnesium alloy,different amount of Ce-rich rare earth(RE)was added to the alloy,and the effect of RE addition on the microstructure and mechanical properties of Mg-10Zn-5Al-0.1Sb alloy was investigated by means of Brinell hardness measurement, scanning electron microscopy(SEM),energy dispersive spectroscope(EDS)and X-ray diffraction(XRD).The results show that an appropriate amount of Ce-rich rare earth addition can make the Al4Ce phase particles and CeSb phase disperse more evenly in the alloy.These phases refine the alloy's matrix and make the secondary phases[?-Mg 32 (Al,Zn)49 phase and?-Al 2 Mg5Zn2 phase]finer and more dispersive,therefore significantly improve the mechanical properties of the Mg-10Zn-5Al-0.1Sb alloy.When the RE addition is 1.0 wt.%,the tensile strengths of the alloy both at room temperature and 150oC reach the maximum values while the impact toughness is slightly lower than that of the matrix alloy.The hardness increases with the increase of RE addition. | You Zhiyong Zhang Zhaoguang Zhang Jinshan Wei Yinghui | 2012 | China Foundry2012，9，2： | 5 |
| 18 | Novel Wx alleles generated by base editing for improvement of rice grain quality显示文摘Amylose content(AC),which is regulated by the Waxy(Wx)gene,is a major indicator of eating and cooking quality(ECQ)in rice(Oryza sativa).Thus far,only a limited number of mutations in the N-terminal domain of Wx were found to have a major impact on the AC of rice grains and no mutations with such effects were reported for other regions of the Wx protein.Here,nucleotide substitutions in the middle region of Wx were generated by adenine and cytosine base editors.The nucleotide substitutions led to changes in 15 amino acid residues of Wx,and a series of novel Wx alleles with ACs of 0.3%-29.43%(wild type with AC of 19.87%)were obtained.Importantly,the waxy~(abe2)allele showed a'soft rice'AC,improved ECQ,favorable appearance,and no undesirable agronomic traits.The transgenes were removed from the waxy~(abe2)progeny,generating a promising breeding material for improving rice grain quality. | Xiaorui Huang Fei Su Sheng Huang Fating Mei Xiaomu Niu Changle Ma Hui Zhang Xiaoguo Zhu Jian-Kang Zhu Jinshan Zhang | 2021 | Journal of Integrative Plant Biology2021，63，9： | 4 |
| 19 | Heterogeneous tide-surge interaction during co-occurrence of tropical and extratropical cyclones in the radial sand ridges of the southern Yellow Sea显示文摘The Radial Sand Ridges(RSRs)area in the southern Yellow Sea are subject to tropical and extratropical cyclone activities frequently,in which the special geometry feature and moving stationary tidal system result in complex storm-induced hydrodynamic processes,especially the tide-surge interactions.We studied a rare weather event influenced simultaneously by an extratropical cyclone EX1410 and Typhoon Vongfong as an example to investigate the characteristics of storm surges,wave-surge,and tide-surge interaction in the RSRs area,and applied a high-resolution integrally-coupled ADCIRC+SWAN model,in which the meteorological forcing inputs are simulated by the WRF-ARW model.The model is validated by records from 4 tide gauges and 2 wave buoys along the Yellow Sea coast.Results show that the tide-surge interactions are of considerable regional heterogeneousness.The surge curves at Lüsi(in south RSRs)and Jianggang(in middle RSRs)have abrupt falls near the time of low tide,where the peak occurrence time of interaction residuals tend to shift towards the mid-ebb period.Significant increase of bed shear stress in shallow waters was proved the dominant factor to affect the tide-surge interaction in broad tidal flats of the RSRs area.Differently,the interaction pattern in the Xiyang Trough(in north RSRs),showed a unique rising in mid-flood period due to the phase advances of real surge waves in relatively deep waters.Therefore,we suggested to the local flood risk management that the tide-surge interaction tends to alleviate the flooding risk in the RSRs area around the time of high tide,but aggravate the risk on the rising tide in the Xiyang Trough and on the falling tide in large-scale tidal flats of the southem RSRs area. | XIONG Mengjie ZHANG Jinshan ZHANG Weisheng YIN Chengtuan | 2019 | Journal of Oceanology and Limnology2019，37，6： | 4 |
| 20 | Corrosion mechanism of CuAl-NiC abradable seal coating system——The influence of porosity,multiphase,and multilayer structure on the corrosion failure显示文摘In this study,the corrosion behavior of the CuAl-NiC abradable seal coating system in chloride solution was investigated to systematically research the effect of porosity,multiphase,and multilayer structure on the corrosion failure.Through the composition and structure analysis,the corrosion process of the system was predicted and then verified with mercury intrusion porosimetry,cross-section SEM/EDS analysis,and electrochemical measurements.The results demonstrated that the interphase selective corrosion caused the porosity of the top layer to decrease first and then increase during the corrosion development.The interlayer galvanic corrosion,determined by the pore connectivity,is crucial for corrosion failure. | Yumeng Ni Fan Zhang Demian I.Njoku Yingjie Yu Jinshan Pan Meijiang Meng Ying Li | 2021 | Journal of Materials Science & Technology2021，，29： | 4 |
