| 2 | Comparison of microstructures and mechanical properties of composite extruded AZ31 sheets显示文摘The microstructures and mechanical properties of the composite extruded AZ31/AZ31 and AZ31/4047 Al sheets were investigated and made a comparison to the conventional extruded AZ31 sheet.Owing to the introduced intense shear deformation at the interface during the composite extrusion,grain refinement and tilted texture were detected in AZ31 layers of the AZ31/AZ31 and AZ31/4047 Al sheets,while the conventional extruded AZ31 sheet exhibited a relative coarse,inhomogeneous microstructure and strong basal texture.The compressiontension yield ratio was increased gradually from the AZ31 to the AZ31/AZ31 and AZ31/4047 Al sheets.Besides,the AZ31/4047 Al sheet could successfully accomplish the whole bending forming process at room temperature,while the AZ31 and AZ31/AZ31 sheets were both bend-formed to failure with significant cracks in the outer tensile region under the identical bending parameters.Moreover,under the same bending strain,both the outward offset degree of strain neutral layer and the sheet thickening were more serious in the AZ31/4047 Al composite sheet than those of the AZ31 and AZ31/AZ31 sheets.The foremost reason was the quite wide gap of material properties between Mg alloy AZ31 layer(tensile loading in the outer region)and Al 4047 layer(compressive loading in the inner region). | Yanfu Chai Yan Song Bin Jiang Jie Fu Zhongtao Jiang Qingshan Yang Haoran Sheng Guangsheng Huang Dingfei Zhang Fusheng Pan | 2019 | Journal of Magnesium and Alloys2019，7，4： | 11 |
| 3 | Influence of different extrusion processes on mechanical properties of magnesium alloy显示文摘AZ31 Mg alloy sheets were processed by the conventional symmetrical extrusion(CSE)and the asymmetric extrusion(ASE).Progressive-asymmetric extrusion(PASE)and severe strain-asymmetric extrusion(SASE)were employed for ASE processes.The texture at near-surface and mid-layer zones of ASE sheets was diverse penetrating the normal direction(ND).This was attributed to an additional asymmetric shear strain deformation during the ASE process.(0002)basal planes of PASE sheets tilt to the shear deformation direction.Meanwhile,the basal texture intensity of PASE sheets has been weakened compared with one in CSE sheets.Grain refinement and tilted weak basal texture obtained by SASE process dramatically enhances the room temperature strength and plasticity of the extruded AZ31 magnesium alloy sheets.The microstructure and mechanical responses were examined and discussed. | Qingshan Yang Bin Jiang Hucheng Pan Bo Song Zhongtao Jiang Jiahong Dai Lifei Wang Fusheng Pan | 2014 | Journal of Magnesium and Alloys2014，2，3： | 11 |
| 4 | Effect of Sn addition on the mechanical properties and bio-corrosion behavior of cytocompatible Mg-4Zn based alloys显示文摘The mechanical properties and bio-corrosion behaviors of as-extruded Mg-4Zn alloys after Sn addition were investigated,systemati-cally.A small amount of Sn addition to Mg-4Zn alloy slightly improved the mechanical properties for solid solution strengthening,and significantly controlled the bio-corrosion rates.Sn participating in the outer layer film formation as SnO/SnO_(2)resisted the bio-corrosion proceeding.Especially,Mg-4Zn-1.5Sn alloy,with a weight loss rate of 0.45 mm/y and hydrogen evolution rate of 0.099 mL/cm^(2)/day,showed cytotoxicity grade of 0 to MC3T3-E1 cells.The perfect alliance of cytocompatibility,suitable mechanical properties and low bio-corrosion rate demonstrates that this Mg-4Zn-1.5Sn alloy is a promising biodegradable magnesium alloy for orthopedic implants. | Weiyan Jiang Jingfeng Wang Weikang Zhao Qingshan Liu Dianming Jiang Shengfeng Guo | 2019 | Journal of Magnesium and Alloys2019，7，1： | 6 |
| 5 | Microstructure and mechanical behavior of the Mg-Mn-Ce magnesium alloy sheets显示文摘The microstructural evolution and mechanical behavior of Mg-Mn-Ce magnesium alloy were investigated in the present study.Mg alloy was prepared with metal model casting method and subsequently hot extruded at 703 K with the reduction ratio of 101:1.The grains were dynamically recrystallized after the extrusion process.Moreover,the(0002)pole figure of Mg-Mn-Ce alloy developed a splitting of pronounced basal texture.The mechanical properties were different due to different angles between c-axis and loading direction(0°,45°and 90°)in the tensile tests.This significantly induces an asymmetry in the yield behavior.The Mg-Mn-Ce alloy exhibits a classical dimple structure as a result of slip accumulation and ductile tear. | Qingshan Yang Bin Jiang Xin Li Hanwu Dong Wenjun Liu Fusheng Pan | 2014 | Journal of Magnesium and Alloys2014，2，1： | 6 |
| 6 | The effects of orientation control via tension-compression on microstructural evolution and mechanical behavior of AZ31 Mg alloy sheet显示文摘The grain orientation control via twinning activity on deformation features is of great significance to offer a key insight into understanding the deformation mechanism of Mg alloy sheets.The{10–12}twinning were performed by pre-strain paths,i.e.,tension(6%)and compression(5%)perpendicular to the c-axis along extrusion direction(ED),to investigate the microstructural evolution and mechanical properties of AZ31 Mg alloy sheets.The distinction in the texture evolution and strain hardening behavior was illustrated in connection with the pre-strain paths for the activities of twinning and slip.The result shows that the activation of the deformation mode was closely bound up with the grain orientation and the additional applied load direction.The{10–12}twin-texture components with c-axis//ED were generated by precompression,which can provide an appropriate alternative to accommodate the thin sheet thickness strain and enhance the room temperature formability of Mg alloy sheet. | Qingshan Yang Bin Jiang Bo Song Zujian Yu Dewei He Yanfu Chai Jianyue Zhang Fusheng Pan | 2022 | Journal of Magnesium and Alloys2022，10，2： | 4 |
| 7 | Improving in vitro and in vivo corrosion resistance and biocompatibility of Mg-1Zn-1Sn alloys by microalloying with Sr显示文摘Magnesium(Mg)and its alloys have attracted attention as potential biodegradable materials in orthopedics due to their mechanical and physical properties,which are compatible with those of human bone.However,the effect of the mismatch between the rapid material degradation and fracture healing caused by the adverse effect of hydrogen(H2),which is generated during degradation,on surrounding bone tissue has severely restricted the application of Mg and its alloys.Thus,the development of new Mg alloys to achieve ideal degradation rates,H2 evolution and mechanical properties is necessary.Herein,a novel Mg-1Zn-1Sn-xSr(x=0,0.2,0.4,and 0.6 wt%)quaternary alloy was developed,and the microstructure,mechanical properties,corrosion behavior and biocompatibility in vitro/vivo were investigated.The results demonstrated that a minor amount of strontium(Sr)(0.2 wt%)enhanced the corrosion resistance and mechanical properties of Mg-1Zn-1Sn alloy through grain refinement and second phase strengthening.Simultaneously,due to the high hydrogen overpotential of tin(Sn),the H2 release of the alloys was significantly reduced.Furthermore,Sr-containing Mg-1Zn-1Sn-based alloys significantly enhanced the viability,adhesion and spreading of MC3T3-E1 cells in vitro due to their unique biological activity and the ability to spontaneously form a network structure layer with micro/nanotopography.A low corrosion rate and improved biocompatibility were also maintained in a rat subcutaneous implantation model.However,excessive Sr(>0.2 wt%)led to a microgalvanic reaction and accelerated corrosion and H2 evolution.Considering the corrosion resistance,H2 evolution,mechanical properties and biocompatibility in vitro and in vivo,Mg-1Zn-1Sn-0.2Sr alloy has tremendous potential for clinical applications. | Yafeng Wen Qingshan Liu Jingfeng Wang Qiming Yang Weikang Zhao Bo Qiao Yuling Li Dianming Jiang | 2021 | Bioactive Materials2021，6，12： | 3 |
| 8 | Formation of Superoxide Radical and Hydrogen Peroxide Enhanced by Trinitrotoluene in Rat Liver, Brain, Kidney, and Testicle in Vitro and Monkey Liver in Vivo显示文摘Trinitrotoluene (TNT) increased the formation of adrenochrome from adrenaline and the formation of formaldehyde from methanol in rat liver mitochondria and microsomes in vitro as well as in monkey liver mitrochondria and microsomes in vivo. The effects were more prominent at higher TNT concentrations. These findings indicate that TNT enhances the production of superoxide radicals (O2-) and hydrogen peroxide (H2O2). The production of O2- was more prominent in systems containing added TNT than in those containing added benzyl viologen. H2O2 production by mitochondria was more pronounced in the liver than in other organs, but its production by microsomes was more pronounced in the brain than in other organs. The results suggest that TNT undergoes cycling reduction which produces oxidative stress. 1989 Academic Press, Inc. | KONG LINGYUAN, JIANG QUANGUAN,~2 AND QU QINGSHAN Department of Occupational Health, School of Public Health, Beijing Medical University, Beijing, China | 1989 | Biomedical and Environmental Sciences1989，2，1： | 3 |
| 9 | High performance perovskite solar cells using TiO2 nanospindles as ultrathin mesoporous layer显示文摘Single crystal anatase TiO_2 nanospindles(NSs) with highly exposed {101} facets were synthesized and employed as electron transport materials(ETMs) in perovskite solar cells(PSCs). Time-resolved photoluminescence(TRPL) spectra revealed that the TiO_2 NSs are more effective than TiO_2 nanoparticles in accepting electrons from perovskite. Moreover, the TiO_2 nanospindles further endowed the PSCs with good reproducibility and suppressed hysteresis. The best device with TiO_2 NSs as ETMs yielded power conversion efficiency(PCE) of 19.6%, demonstrating that the home-made TiO_2 NSs is a good ETM for PSCs. | Yinhua Lv Bing Cai Yihui Wu Shubo Wang Qike Jiang Qingshan Ma Jingyue(Jimmy)Liu Wen-Hua Zhang | 2018 | Journal of Energy Chemistry2018，27，4： | 2 |

| 11 | Twinning, grain orientation, and texture variations in Mg alloy processed by pre-rolling显示文摘A pre-rolling(PR) process with a small pre-strain was applied along the transverse direction(TD) and the extrusion direction(ED) of non-basal and basal textured AZ61 Mg alloys at room temperature to investigate the induced twinning behavior. The microstructural evolution of the alloys was used to evaluate the grain-boundary effect in terms of the texture variation. The results demonstrated that■ extension twinning was introduced by the PR process and that the volume fraction of twins increased with increasing thickness reduction. The subdivision of grains via twinning induced grain reorientation that generated a prominent basal texture with the c-axis parallel to the normal direction(ND) after PR. The textured Mg alloy with this c-axis//TD feature can promote twinning activity. The twinning performance was critical to initiate plastic deformation, therefore to determine deformation behavior at room temperature. The deformation mechanism was also addressed related to the extension twin lamellae. | Qingshan Yang Qingwei Dai Chao Lou Jiahong Dai Jianyue Zhang Bin Jiang Fusheng Pan | 2019 | Progress in Natural Science:Materials International2019，29，2： | 2 |
| 12 | SPM-IS: An auto-algorithm to acquire a mature soybean phenotype based on instance segmentation显示文摘Mature soybean phenotyping is an important process in soybean breeding;however, the manual process is time-consuming and labor-intensive. Therefore, a novel approach that is rapid, accurate and highly precise is required to obtain the phenotypic data of soybean stems, pods and seeds. In this research, we propose a mature soybean phenotype measurement algorithm called Soybean Phenotype Measure-instance Segmentation(SPM-IS). SPM-IS is based on a feature pyramid network, Principal Component Analysis(PCA) and instance segmentation. We also propose a new method that uses PCA to locate and measure the length and width of a target object via image instance segmentation. After 60,000 iterations, the maximum mean Average Precision(m AP) of the mask and box was able to reach 95.7%. The correlation coefficients R^(2) of the manual measurement and SPM-IS measurement of the pod length, pod width, stem length, complete main stem length, seed length and seed width were 0.9755, 0.9872, 0.9692, 0.9803,0.9656, and 0.9716, respectively. The correlation coefficients R^(2) of the manual counting and SPM-IS counting of pods, stems and seeds were 0.9733, 0.9872, and 0.9851, respectively. The above results show that SPM-IS is a robust measurement and counting algorithm that can reduce labor intensity, improve efficiency and speed up the soybean breeding process. | Shuai Li Zhuangzhuang Yan Yixin Guo Xiaoyan Su Yangyang Cao Bofeng Jiang Fei Yang Zhanguo Zhang Dawei Xin Qingshan Chen Rongsheng Zhu | 2022 | The Crop Journal2022，10，5： | 2 |

| 15 | An integrated model for predicting the flame propagation in crimped ribbon flame arresters显示文摘Crimped ribbon flame arresters are important safety devices in the chemical industry, especially for the dangerous situations. Although proper design of arresters by the numerical simulation method is promising, its reliability and accuracy are dependent upon the mathematical model. In this work, an integrated mathematical model for the microchannel in the crimped ribbon flame arresters was set up; the fluid flow behavior and the sensitivities of four chemical kinetics mechanisms of propane-air on the accuracy were analysed. It is shown that turbulence is predominant in the microchannel of the crimped ribbon flame arresters under the deflagration and detonation conditions, and a new quenching criterion for the numerical simulation is proposed. The kinetics mechanism of Mansouri et al. among the four ones is the most accurate due to the best agreement of the predicted outlet temperature at the experimental flameproof velocity with the autoignition temperature of propane-air. The species mass fraction profiles and the temperature distribution, which are too difficult to measure due to the tiny dimension of the microchannel in experiments, are captured. The fundamental insights into chemical reactions and heat loss are well portrayed. It can be concluded that the integrated mathematical model established in this work can be used as a reliable tool for modeling, selecting and designing such type of crimped ribbon flame arresters with the propane-air medium in the future. | Zheng Wang Bing Sun Qingshan Huang Fuhua Jiang | 2018 | Chinese Journal of Chemical Engineering2018，26，5： | 1 |

| 19 | Migration routes,behavior and protection status of Eurasian Spoonbills(Platalea leucorodia)wintering in China显示文摘Background:The Eurasian Spoonbill(Platalea leucorodia)occurs throughout Eurasia and North and sub-Saharan Africa,with three recognized subspecies and six geographically distributed populations.However,in China,we knew almost nothing about migration routes,habitat use and effectiveness of current site protection measures for this species.Methods:We deployed Global Positioning System/Global System for Mobile Communications(GPS/GSM)satellite trackers on 29 Eurasian Spoonbills captured in summer in Mongolia and northeastern China,to obtain complete migration routes data from 10 individuals from 19 complete migration episodes.Results:Tracking data showed no geographical overlap during the annual cycle in Eurasian Spoonbills marked in the two main summering areas.Birds marked in the Naoli River Basin in Heilongjiang Province,China,wintered along the Jiangsu coastline in China,while Eurasian Spoonbills from two discrete summering areas(in Inner and western Mon-golia)overwintered inland in the Yangtze River floodplain of China.Excluding the single Inner Mongolian bird,spring migration was significantly faster than autumn migration in the other two groups of birds.Eurasian Spoonbills mainly used water,wetland and grassland habitats in summer,but almost exclusively water in winter.Lack of protection of staging sites used by all the birds in spring and poor levels of protection throughout the annual cycle for western Mongolian birds(5-22%)gives considerable cause for concern,although sites used in other time by East Mongolian and Naoli River birds in the rest of their annual life cycle enjoyed good levels of protection(49-95%).Conclusions:These results revealed previously unknown relationships between summering and wintering areas,migration routes and stopover sites for Eurasian Spoonbills wintering in China,suggesting the existence of discrete biogeographical population units.They also identified winter habitat use of Eurasian Spoonbills in China,confirming open water habitats as being critical throughout the annual cycle,although based on small sample size,gaps in cur-rent site safeguard networks for these populations. | Jire Xi Xueqin Deng Gerelt Zhao Nyambayar Batbayar Iderbat Damba Qingshan Zhao Shoubin Cui Chao Jiang Yiwen Chen Yat-tung Yu Lei Cao Anthony David Fox | 2021 | Avian Research2021，12，4： | 1 |
