| 1 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 51 |

| 3 | Chemical characteristics of size-resolved aerosols in winter in Beijing显示文摘Size-resolved aerosols were continuously collected by a Nano Sampler for 13 days at an urban site in Beijing during winter 2012 to measure the chemical composition of ambient aerosol particles. Data collected by the Nano Sampler and an ACSM(Aerodyne Aerosol Chemical Speciation Monitor) were compared. Between the data sets,similar trends and strong correlations were observed,demonstrating the validity of the Nano Sampler. PM10 and PM2.5concentrations during the measurement were 150.5 ± 96.0 μg/m3(mean ± standard variation)and 106.9 ± 71.6 μg/m3,respectively. The PM2.5/PM10 ratio was 0.70 ± 0.10,indicating that PM2.5dominated PM10. The aerosol size distributions showed that three size bins of 0.5–1,1–2.5 and 2.5–10 μm contributed 21.8%,23.3% and 26.0% to the total mass concentration(TMC),respectively. OM(organic matter) and SIA(secondary ionic aerosol,mainly SO42-,NO3-and NH4+) were major components of PM2.5. Secondary compounds(SIA and secondary organic carbon) accounted for half of TMC(about 49.8%) in PM2.5,and suggested that secondary aerosols significantly contributed to the serious particulate matter pollution observed in winter. Coal burning,biomass combustion,vehicle emissions and SIA were found to be the main sources of PM2.5. Mass concentrations of water-soluble ions and undetected materials,as well as their fractions in TMC,strikingly increased with deteriorating particle pollution conditions,while OM and EC(elemental carbon) exhibited different variations,with mass concentrations slightly increasing but fractions in TMC decreasing. | Kang Sun Yu Qu Qiong Wu Tingting Han Jianwei Gu Jingjing Zhao Yele Sun Qi Jiang Ziqi Gao Min Hu Yuanhang Zhang Keding Lu Stephan Nordmann Yafang Cheng Li Hou Hui Ge Masami Furuuchi Mitsuhiko Hata Xingang Liu | 2014 | Journal of Environmental Sciences2014,26,8: | 9 |
| 4 | Simultaneously Regulating Uniform Zn^(2+) Flux and Electron Conduction by MOF/rGO Interlayers for High‑Performance Zn Anodes显示文摘Owing to the merits of low cost,high safety and environmental benignity,rechargeable aqueous Zn-based batteries(ZBs)have gained tremendous attention in recent years.Nevertheless,the poor reversibility of Zn anodes that originates from dendrite growth,surface passivation and corrosion,severely hinders the further development of ZBs.To tackle these issues,here we report a Janus separator based on a Zn-ion conductive metal-organic framework(MOF)and reduced graphene oxide(rGO),which is able to regulate uniform Zn2+flux and electron conduction simultaneously during battery operation.Facilitated by the MOF/rGO bifunctional interlayers,the Zn anodes demonstrate stable plating/stripping behavior(over 500 h at 1 mA cm^(−2)),high Coulombic efficiency(99.2%at 2 mA cm^(−2) after 100 cycles)and reduced redox barrier.Moreover,it is also found that the Zn corrosion can be effectively retarded through diminishing the potential discrepancy on Zn surface.Such a separator engineering also saliently promotes the overall performance of Zn|MnO2 full cells,which deliver nearly 100%capacity retention after 2000 cycles at 4 A g^(−1) and high power density over 10 kW kg^(−1).This work provides a feasible route to the high-performance Zn anodes for ZBs. | Ziqi Wang Liubing Dong Weiyuan Huang Hao Jia Qinghe Zhao Yidi Wang Bin Fei Feng Pan | 2021 | Nano-Micro Letters2021,13,5: | 3 |
| 5 | Effect of rare earth on the performance of Ru/MgAl-LDO catalysts for ammonia synthesis显示文摘A series of MgAl-layered double oxides(LDO) doped with different rare-earth elements(Y, La, and Ce)were synthesized by the calcination of Mg-Al layered double hydroxides, and Ru, which were used to prepare ammonia synthesis catalysts. The as-obtained oxides and catalysts were characterized by XRD,TEM, TPD, TPR and XPS to understand their catalytic performances in ammonia synthesis. The H_2-TPR and HRTEM studies reveal that Ru/Y-LDO catalyst possesses more active Ru metal and small particle size.The XPS demonstrates that the electronic interaction between Y and Ru metals is stronger, which can be tentatively explained by most of Y inserted into the hydrotalcites structure. CO_2-TPD demonstrates that Ru/Y-LDO catalyst shows stronger basic site densities than catalysts doped with Ce and La. Higher activity of the Ru/Y-LDO catalyst can be attributed to smaller particle size, more active metal(Ru) and strong Ru-support interaction. | Jun Ni Baoqiang Jing Jianxin Lin Bingyu Lin Ziqi Zhao Lilong Jiang | 2018 | Journal of Rare Earths2018,36,2: | 3 |
| 6 | Numerical modeling of metamorphic core complex formation:Implications for the destruction of the North China Craton显示文摘Widespread magmatism, metamorphic core complexes(MCCs), and significant lithospheric thinning occurred during the Mesozoic in the North China Craton(NCC). It has been suggested that the coeval exhumation of MCCs with uniform northwest-southeast shear senses and magmatism probably resulted from a decratonization event during the retreat of the paleo-Pacific Plate. Here we used two-dimensional finite element thermomechanical numerical models to investigate critical parameters controlling the formation of MCCs under far-field extensional stress. We observed three end-member deformation modes: the MCC mode, the symmetric-dome mode, and the pure-shear mode. The MCC mode requires a Moho temperature of ≥700 ℃ and an extensional strain rate of ≥5 × 10^(-16)s^(-1), implying that the lithosphere had already thinned when the MCC was formed in the Mesozoic. Considering that the widespread MCCs have the same northwest-southeast extension direction in the NCC, we suggest that the MCCs are surface expressions of both large-scale extension and craton destruction and that rollback of the paleo-Pacific slab might be the common driving force. | ZiQi Ma Gang Lu JianFeng Yang Liang Zhao | 2022 | Earth and Planetary Physics2022,6,2: | 2 |
| 7 | Histones released by NETosis enhance the infectivity of SARS-CoV-2 by bridging the spike protein subunit 2 and sialic acid on host cells显示文摘Neutrophil extracellular traps(NETs)can capture and kill viruses,such as influenza viruses,human immunodeficiency virus(HIV),and respiratory syncytial virus(RSV),thus contributing to host defense.Contrary to our expectation,we show here that the histones released by NETosis enhance the infectivity of SARS-CoV-2,as found by using live SARS-CoV-2 and two pseudovirus systems as well as a mouse model.The histone H3 or H4 selectively binds to subunit 2 of the spike(S)protein,as shown by a biochemical binding assay,surface plasmon resonance and binding energy calculation as well as the construction of a mutant S protein by replacing four acidic amino acids.Sialic acid on the host cell surface is the key molecule to which histones bridge subunit 2 of the S protein.Moreover,histones enhance cell-cell fusion.Finally,treatment with an inhibitor of NETosis,histone H3 or H4,or sialic acid notably affected the levels of sgRNA copies and the number of apoptotic cells in a mouse model.These findings suggest that SARS-CoV-2 could hijack histones from neutrophil NETosis to promote its host cell attachment and entry process and may be important in exploring pathogenesis and possible strategies to develop new effective therapies for COVID-19. | Weiqi Hong Jingyun Yang Jun Zou Zhenfei Bi Cai He Hong Lei Xuemei He Xue Li Aqu Alu Wenyan Ren Zeng Wang Xiaohua Jiang Kunhong Zhong Guowen Jia Yun Yang Wenhai Yu Qing Huang Mengli Yang Yanan Zhou Yuan Zhao Dexuan Kuang Junbin Wang Haixuan Wang Siyuan Chen Min Luo Ziqi Zhang Tiangi Lu Li Chen Haiying Que Zhiyao He Qiu Sun Wei Wang Guobo Shen Guangwen Lu Zhiwei Zhao Li Yang Jinliang Yang Zhenling Wang Jiong Li Xiangrong Song Lunzhi Dai Chong Chen Jia Geng Maling Gou Lu Chen Haohao Dong Yong Peng Canhua Huang Zhiyong Qian Wei Cheng Changfa Fan Yuquan Wei Zhaoming Su Aiping Tong Shuaiyao Lu Xiaozhong Peng Xiawei Wei | 2022 | Cellular & Molecular Immunology2022,19,5: | 2 |
| 8 | QTL mapping of quality traits in peanut using whole-genome resequencing显示文摘Oil and protein content and fatty acid composition are quality traits in peanut.Elucidating the genetic mechanisms underlying these traits may help researchers to obtain improved cultivars by molecular breeding.Whole-genome resequencing of a recombinant inbred population of 318 lines was performed to construct a high-density linkage map and identify QTL for peanut quality.The map,containing 4561 bin markers,covered 2032 c M with a mean marker density of 0.45 c M.A total of 110 QTL for oil and protein content,and fatty acid composition were mapped on the 18 peanut chromosomes.The QTL q A05.1 was detected in four environments and showed a major phenotypic effect on the contents of oil,protein,and six fatty acids.The genomic region spanned by q A05.1,corresponding to a physical interval of approximately 1.5 Mb,contains two SNPs polymorphic between the parents that could cause missense mutations.The two SNP sites were employed as KASP markers and validated using lines with extremely high and low oil contents.These sites may be useful in the marker-assisted breeding of peanut cultivars with high oil contents. | Ziqi Sun Feiyan Qi Hua Liu Li Qin Jing Xu Lei Shi Zhongxin Zhang Lijuan Miao Bingyan Huang Wenzhao Dong Xiao Wang Mengdi Tian Jingjing Feng Ruifang Zhao Xinyou Zhang Zheng Zheng | 2022 | The Crop Journal2022,10,1: | 2 |

| 11 | A raster-based typification method for multiscale visualization of building features considering distribution patterns显示文摘In map multiscale visualization,typification is the process of replacing original objects,such as buildings,using a smaller number of objects while maintaining initial geometrical and distribution characteristics.During the past few decades,many vector-based methods for building typification have been developed,whereas raster-based methods have received less attention.In this paper,a new method for the typification of buildings with different distribution patterns called superpixel building typification(SUBT)is developed based on raster data.Using this method,buildings with different distribution patterns,such as linear,grid and irregular patterns,are first grouped by image connected component detection and superpixel analysis.Then,the new positions for building typification are determined by superpixel resegmentation.Finally,a new representation of the buildings is determined through analysis of the orientation and shape of the buildings in each superpixel.To test the proposed SUBT method,buildings from both cities and countrysides in China are applied to perform typification.The experimental results show that the proposed SUBT method can realize typification for buildings with linear,grid and irregular distributions while effectively maintaining the original distribution characteristics of the buildings. | Yilang Shen Jingzhong Li Ziqi Wang Rong Zhao Lu Wang | 2022 | International Journal of Digital Earth2022,15,1: | 1 |
| 12 | Heavy metals in agricultural soil in China: A systematic review and meta-analysis显示文摘Research about farmland pollution by heavy metals/metalloids in China has drawn growing attention.However,there was rare information on spatiotemporal evolution and pollution levels of heavy metals in the major grainproducing areas.We extracted and examined data from 276 publications between 2010 and 2021 covering five major grain-producing regions in China from 2010 to 2021.Spatiotemporal evolution characteristics of main heavy metals/metalloids was obtained by meta-analysis.In addition,subgroup analyses were carried out to study preliminary correlations related to accumulation of the pollutants.Cadmium(Cd)was found to be the most prevailing pollutant in the regions in terms of both spatial distribution and temporal accumulation.The Huang-Huai-Hai Plain was the most severely polluted.Accumulation of Cd,mercury(Hg)and copper(Cu)increased from 2010 to 2015 when compared with the 1990 background data.Further,the levels of five key heavy metals(Cd,Cu,Hg,lead[Pb]and zinc[Zn])showed increasing trends from 2016 to 2021 in all five regions.Soil pH and mean annual precipitation had variable influences on heavy metal accumulation.Alkaline soil and areas with less rainfall faced higher pollution levels.Farmlands cropped with mixed species showed smaller effect sizes of heavy metals than those with single upland crop,suggesting that mixed farmland use patterns could alleviate the levels of heavy metals in soil.Of various soil remediation efforts,farmland projects only held a small market share.The findings are important to support the research of risk assessment,regulatory development,pollution prevention,fund allocation and remediation actions. | Moyan Wen Ziqi Ma Daniel BGingerich Xiao Zhao Dongye Zhao | 2022 | Eco-Environment & Health2022,1,4: | 1 |

| 14 | Current status of greenhouse gas emissions from aquaculture in China显示文摘Aquaculture and mariculture are becoming an increasingly important source of food supply in many countries and regions.However,with the expansion of aquaculture and mariculture comes increasing emissions of greenhouse gases(GHG)which contribute to global warming and climate change.China leads the world in aquaculture and mariculture production,but there are no studies that systematically assess China's overall carbon footprint from these industries.This study quantified GHG emissions from aquaculture and mariculture by four source phases(feed,energy use,nitrous oxide and fertilizers),and then analyzed the carbon footprint of each of these phases for GHG production of nine major species groups over the past ten years to show the spatial distribution of GHG emissions from aquaculture and mariculture in China.Our results showed that the production of feed materials contributed most to the GHG emissions and found that crop energy use,crop land use changes(LUC),fertilizer production,crop nitrous oxide production and rice methane production were the main sources of feed emissions.The total GHG emissions of the nine species groups were 112 Mt(10^(9) kg)CO_(2)e,the nine species accounting for approximately 86%of aquaculture and mariculture production.GHG emissions of cyprinids had the highest contribution at 47%.Spatial analysis based on our study showed Guangdong,Hubei,Jiangsu and Shandong had the highest GHG emissions of all the provinces in this study,and they accounted for approximately 46%of all emissions.The regional Gross Domestic Product(GDP)was significantly positively correlated with GHG emissions in every province,with a correlation coefficient higher than 0.6.Our results showed for the first time the relationship between the relative production by species composition and spatial distribution of GHG emissions from aquaculture and mariculture in China.Our findings provide the scientific basis for reduction of GHG emissions within a broader context of expanding aquaculture in the future. | Congjun Xu Guohuan Su Kangshun Zhao Xiaoqi Xu Ziqi Li Qiang Hu Ying Xue Jun Xu | 2022 | Water Biology and Security2022,1,3: | 1 |
| 15 | Excellent mechanical properties and large magnetocaloric effect of spark plasma sintered Ni-Mn-In-Co alloy显示文摘The Ni43.75Mn37.5In12.5Co6.25 alloy was obtained by using the spark plasma sintering(SPS)technique.The martensitic transformation,magnetic and mechanical properties of the SPS alloy were investigated.Key findings demonstrate that the martensitic transformation temperature of this alloy is about 10 K lower than that of the as-cast one.Both SPS and as-cast alloys show a 7 layered modulated martensite(7M)at room temperature.The compressive fracture strength and strain of the SPS alloy increase by 176.92%and 33.33%compared with the as-cast alloy,achieving 1440 MPa and 14%,respectively.The maximum magnetic entropy change Smis 17.1 J kg^(-1)K^(-1)for the SPS alloy at the magnetic field of 5 T. | Jing Bai Die Liu Jianglong Gu Xinjun Jiang Xinzeng Liang Ziqi Guan Yudong Zhang Claude Esling Xiang Zhao Liang Zuo | 2021 | Journal of Materials Science & Technology2021,,15: | 1 |
| 16 | First-principles calculations of Ni–(Co)–Mn–Cu–Ti all-d-metal Heusler alloy on martensitic transformation,mechanical and magnetic properties显示文摘The martensitic transformation,mechanical,and magnetic properties of the Ni_(2)Mn_(1.5-x)Cu_(x)Ti_(0.5) (x=0.125,0.25,0.375,0.5) and Ni_(2-y)Co_(y)Mn_(1.5-x)Cu_(x)Ti_(0.5)[(x=0.125,y=0.125,0.25,0.375,0.5) and (x=0.125,0.25,0.375,y=0.625)]alloys were systematically studied by the first-principles calculations.For the formation energy,the martensite is smaller than the austenite,the Ni–(Co)–Mn–Cu–Ti alloys studied in this work can undergo martensitic transformation.The austenite and non-modulated (NM) martensite always present antiferromagnetic state in the Ni_(2)Mn_(1.5-x)Cu_(x)Ti_(0.5) and Ni_(2-y)Co_(y)Mn_(1.5-x)Cu_(x)Ti_(0.5) (y<0.625) alloys.When y=0.625 in the Ni_(2-y)Co_(y)Mn_(1.5-x)Cu_(x)Ti_(0.5) series,the austenite presents ferromagnetic state while the NM martensite shows antiferromagnetic state.Cu doping can decrease the thermal hysteresis and anisotropy of the Ni–(Co)–Mn–Ti alloy.Increasing Mn and decreasing Ti content can improve the shear resistance and normal stress resistance,but reduce the toughness in the Ni–Mn–Cu–Ti alloy.And the ductility of the Co–Cu co-doping alloy is inferior to that of the Ni–Mn–Cu–Ti and Ni–Co–Mn–Ti alloys.The electronic density of states was studied to reveal the essence of the mechanical and magnetic properties. | Huaxin Qi Jing Bai Miao Jin Jiaxin Xu Xin Liu Ziqi Guan Jianglong Gu Daoyong Cong Xiang Zhao Liang Zuo | 2023 | International Journal of Minerals,Metallurgy and Materials2023,30,5: | 1 |
| 17 | High drug loading and pH-responsive nanomedicines driven by dynamic boronate covalent chemistry for potent cancer immunotherapy显示文摘Tumor cells undergoing immunogenic cell death (ICD) have emerged as an in situ therapeutic vaccine helping to activate a persistent anti-tumor response. Several chemotherapeutic agents have been demonstrated to induce ICD, however accompanied with severe adverse effects in the clinic, weakening its immune responses. Herein, to elicit an intensive ICD while minimizing the systemic toxicity, we introduce a tumor targeting peptide modified bortezomib (BTZ) loading nanomedicine (i-NPBTZ) for the efficient delivery and controlled release of BTZ in tumors. This system is constructed by conjugating BTZ to PEGylated polyphenols via a pH-sensitive covalent boronate-phenol bond that allows them to self-assemble into nanovesicles in neutral condition with high drug loading efficiency. Once accumulated in acidic environment, BTZ-phenolic network is disassembled and thereby accelerates the release of BTZ from nanocarriers. The released BTZ selectively kill tumor cells with a concomitant evocation of tumor-specific cytotoxic T cells by triggering ICD in vivo. This can finally lead to an extended tumor ablation and prevention of distant metastasis in a syngeneic tumor mouse model, while reducing the systemic toxicity of BTZ. In general, our system offers a novel concept with clinical potential to exploit ICD for potentiating tumor immunotherapy and also provides an excellent example of the application of polymer-drug interaction for efficient drug delivery and controllable release. | Wei Jiang Han Zhou Qin Wang Ziqi Chen Wang Dong Zixuan Guo Yong Li Wei Zhao Meixiao Zhan Yucai Wang Ligong Lu | 2021 | Nano Research2021,14,11: | 1 |
| 18 | Evolutionarily conservative and non-conservative regulatory networks during primate interneuron development revealed by single-cell RNA and ATAC sequencing显示文摘The differences in size and function between primate and rodent brains,and the association of disturbed excitatory/inhibitory balance with many neurodevelopmental disorders highlight the importance to study primate ganglionic eminences(GEs)development.Here we used single-cell RNA and ATAC sequencing to characterize the emergence of cell diversity in monkey and human GEs where most striatal and cortical interneurons are generated.We identified regional and temporal diversity among progenitor cells which give rise to a variety of interneurons.These cells are specified within the primate GEs by well conserved gene regulatory networks,similar to those identified in mice.However,we detected,in human,several novel regulatory pathways or factors involved in the specification and migration of interneurons.Importantly,comparison of progenitors between our human and published mouse GE datasets led to the discovery and confirmation of outer radial glial cells in GEs in human cortex.Our findings reveal both evolutionarily conservative and nonconservative regulatory networks in primate GEs,which may contribute to their larger brain sizes and more complex neural networks compared with mouse. | Ziqi Zhao Dan Zhang Fuqiang Yang Mingrui Xu Shaoli Zhao Taotao Pan Chuanyu Liu Yongjie Liu Qingfeng Wu Qiang Tu Ping Zhou Rong Li Jia Kang Lan Zhu Fei Gao Yaqing Wang Zhiheng Xu | 2022 | Cell Research2022,32,5: | 1 |
| 19 | Promoting near-infrared II fluorescence efficiency by blocking long-range energy migration显示文摘Generally,long wavelength absorbed near-infrared II(NIR-II)dyes have a low fluorescence efficiency in aggregate states for aggregate-caused quenching effect,simultaneously enhancing efficiency and extending absorption is a challenging issue for NIR-II dyes.Here,three benzo[1,2-c:4,5-c’]bis[1,2,5]thiadiazole(BBT)derivatives(TPA-BBT,FT-BBT,and BTBT-BBT)are used to clarify fluorescence quenching mechanisms.When the BBT derivatives are doped into a small molecule matrix,they show quite different fluorescence behaviors.Structuredistorted TPA-BBT displays fluorescence quenching originating from short-range exchange interaction,while FT-BBT and BTBT-BBT with a co-planar-conjugated backbone exhibit concentration-dependent quenching processes,namely changing from long-range dipole-dipole interaction to exchange interaction,which could be majorly ascribed to large spectral overlap between absorption and emission.By precisely tuning doping concentration,both FT-BBT and BTBT-BBT nanoparticles(NPs)present the optimal NIR-II fluorescence brightness at∼2.5 wt%doping concentration.The doped NPs have good biocompatibility and could be served as fluorescence contrast agents for vascular imaging with a high resolution under 980-nm laser excitation.Those paradigms evidence that molecular doping can promote fluorescence efficiency of long wavelength-absorbed NIR-II fluorophores via suppressing long-range energy migration. | Changjin Ou Lei An Ziqi Zhao Fan Gao Liangyu Zheng Chao Xu Kang Zhang Jinjun Shao Linghai Xie Xiaochen Dong | 2023 | Aggregate2023,4,3: | 0 |
| 20 | First-principles investigation of B2 partial disordered structure,martensitic transformation, elastic and magnetic properties of all-d-metal Ni-Mn-Ti Heusler alloys显示文摘In this work,the B2 partial disordered structure of the austenitic parent phase,martensitic transformation,elastic and magnetic properties of the Ni8 Mn4+xTi4-x(x=0,1 and 2) Heusler alloys have been systematically investigated by the first-principles calculations.The preferential atomic occupation of B2 structure is one Ti atom exchange with the nearest neighboring Mn atom from the view of lowest energy principle.This disordered exchange sites(Mn-Ti) and the excess Mn atoms occupying the Ti sites(MnTi)could reduce the nearest Mn-Mn distance,resulting in the anti ferromagnetic state in the austenitic and martensitic phases of the alloys.The total magnetic moment of the alloy decreases with the increasing Mn content;it is ascribed to the antiferromagnetic magnetic moments of the excess Mn atoms.When x=0,the alloy does not undergo martensitic transformation since the austenite has absolute phase stability.The martensitic transformation will occur during cooling process for x=1 or 2,owing to the energy difference between the austenite and the martensite could provide the driving force for the phase transformation.The elastic properties of the cubic austenitic phase for the Ni2 MnTi alloy is calculated,and the results reveal the reason why Ni-Mn-Ti alloy has excellent mechanical properties.The origin of martensitic transformation and magnetic properties was discussed based on the electronic density of states. | Ziqi Guan Jing Bai Jianglong Gu Xinzeng Liang Die Liu Xinjun Jiang Xiang Zhao Liang Zuo | 2021 | Journal of Materials Science & Technology2021,,9: | 0 |
