| 1 | Challenges and Solutions for the Additive Manufacturing of H) Biodegradable Magnesium Implants显示文摘Due to their capability of fabricating geometrically complex structures,additive manufacturing(AM)techniques have provided unprecedented opportunities to produce biodegradable metallic implants—especially using Mg alloys,which exhibit appropriate mechanical properties and outstanding biocompatibility.However,many challenges hinder the fabrication of AM-processed biodegradable Mg-based implants,such as the difficulty of Mg powder preparation,powder splash,and crack formation during the AM process.In the present work,the challenges of AM-processed Mg components are analyzed and solutions to these challenges are proposed.A novel Mg-based alloy(Mg-Nd-Zn-Zr alloy,JDBM)powder with a smooth surface and good roundness was first synthesized successfully,and the AM parameters for Mg-based alloys were optimized.Based on the optimized parameters,porous JDBM scaffolds with three different architectures(biomimetic,diamond,and gyroid)were then fabricated by selective laser melting(SLM),and their mechanical properties and degradation behavior were evaluated.Finally,the gyroid scaffolds with the best performance were selected for dicalcium phosphate dihydrate(DCPD)coating treatment,which greatly suppressed the degradation rate and increased the cytocompatibility,indicating a promising prospect for clinical application as bone tissue engineering scaffolds. | Yinchuan Wang Penghuai Fu Nanqing Wang Liming Peng Bin Kang Hui Zeng Guangyin Yuan Wenjiang Ding | 2020 | Engineering2020，6，11： | 10 |
| 2 | In vitro degradation and biocompatibility of Mg-Nd-Zn-Zr alloy显示文摘In this study,in vitro degradation and biocompatibility of Mg-Nd-Zn-Zr(NZK) alloy were investigated to determine its suitability as a degradable medical biomaterial.Its corrosion properties were evaluated by static immersion test,electrochemical corrosion test,scanning electron microscopy(SEM),and energy dispersive spectroscopic(EDS) analysis,and in vitro biocompatibilities were assessed by hemolysis and cytotoxicity tests.Pure magnesium was used as control.The results of static immersion test and electrochemical corrosion test in simulated body fluid(SBF) demonstrated that the addition of alloying elements could improve the corrosion resistance.The hemolysis test found that the hemolysis rate of calcium phosphate coated NZK alloy was 4.8%,which was lower than the safe value of 5%.The cytotoxicity test indicated that NZK alloy extracts did not significantly reduce MC3T3-E1 cell viability.Hemolysis test and cytotoxicity test display excellent hemocompatibility and cytocompatibility of NZK alloy in vitro.Our data indicate that NZK alloy has excellent biocompatibility and thus can be considered as a potential degradable medical biomaterial for orthopedic applications. | WANG YongPing HE YaoHua ZHU ZhaoJin JIANG Yao ZHANG Jian NIU JiaLin MAO Lin YUAN GuangYin | 2012 | Chinese Science Bulletin2012，57，17： | 8 |

| 5 | Fabrication of ultra-high strength magnesium alloys over 540 MPa with low alloying concentration by double continuously extrusion显示文摘We prepare a new type of patented biodegradable biomedical Mg-Nd-Zn-Zr(JDBM)alloy system and impose double continuously extrusion(DCE)processing.The lowest processing temperature is 250℃for JDBM-2.1Nd and 310℃for JDBM-2.8Nd,which increases with the Nd concentration.The highest yield strength of 541 MPa is achieved in JDBM-2.1 Nd samples when extruded at 250℃and the elongation is about 3.7%.Moreover,the alloy with a lower alloying element content can reach a higher yield strength while that with a higher alloying element content can reach a larger elongation after DCE processing.However,when extruded under the same conditions,the alloy with a higher alloying contents exhibits better tensile properties. | Hua Huang Hongwei Miao Guangyin Yuan Zhongchang Wang Wenjiang Ding | 2018 | Journal of Magnesium and Alloys2018，6，2： | 3 |
| 6 | Simulation-based optimization of control policy on multi-echelon inventory system for fresh agricultural products显示文摘As fresh agricultural products are perishable and vulnerable,reducing inventory cost is a strategic target for supply chain enterprises.How to design a reliable multi-echelon inventory control policy is still a great challenge.Therefore,the inventory cost of a three-level fresh agricultural products inventory system was firstly mathematically analyzed.Then,the simulation-based optimization model of the multi-echelon inventory system for fresh agricultural products was proposed by using the Flexsim simulation software and the improved particle swarm optimization algorithm.Finally,the multi-echelon inventory system is simulated based on a large number of survey data.Simulation results demonstrate that the proposed simulation-based optimization model of multi-echelon inventory system for fresh agricultural products can provide decision-making and technical support for the formulation of inventory control policy,and also it shows that the modeling of system simulation is an effective method to solve the problem of complex system. | Guangyin Xu Jihao Feng Fenglei Chen Heng Wang Zhenfeng Wang | 2019 | International Journal of Agricultural and Biological Engineering2019，12，2： | 2 |

| 8 | Biocompatibility of Mg-Nd-Zn-Zr alloy with rabbit blood显示文摘In this study, in vitro blood biocompatibility of Mg-Nd-Zn-Zr (JDBM) alloy was investigated to determine its suitability as a degradable medical biomaterial. Blood biocompatibility was assessed by blood cell aggregation, platelet adhesion, and protein adsorption. A titanium alloy was used as control. The results showed that the JDBM alloy did not induce significant blood cell aggregation, platelet adhesion, and protein adsorption comparison with the titanium alloy (P>0.05). Our data indicate that the JDBM alloy has excellent in vitro blood compatibility, and thus can be considered as a potential degradable biomaterial for medical applications with respect to hemocompatibility. | WANG YongPing OUYANG YuanMing HE YaoHua CHEN DaoYun JIANG Yao MAO Lin NIU JiaLin ZHANG Jian YUAN GuangYin | 2013 | Chinese Science Bulletin2013，58，23： | 2 |

| 13 | Effect of grain size on the mechanical properties of Mg foams显示文摘The grain size of Mg foams was innovatively refined without alteration of pore structure and relative density by subjecting multi-axial forging(MAF)process to Ti-Mg composite,an intermediary product of the fabrication process of Mg foams where the spherical Ti particles were utilized as the replication material.The feasibility of the MAF process and the grain size effect on the mechanical properties of Mg foams were discussed.The results showed that,with the appropriate strain of 0.24 applied in the MAF process,Ti-Mg composites returned to original physical appearance without generating microcracks.And complete recrystallization was achieved after heat treatment,with the grain size of the MAFprocessed Mg foams two to three orders of magnitude smaller than that of as-cast foam.The mechanical properties of Mg foams were enhanced extensively after grain refinement with the yield strength and the plastic collapse strength increased by 147%and 50.7%,respectively.A revised model integrated by the Hall-Petch law and Gibson-Ashby model was proposed,which gave a good estimation of the yield strength and the plastic collapse strength of Mg foams from the compressive behavior of the corresponding parent material,though a knockdown factor of 0.45 was introduced for the yield strength. | Yinchuan Wang Hua Huang Gaozhi Jia Guizhou Ke Jian Zhang Guangyin Yuan | 2020 | Journal of Materials Science & Technology2020，58，23： | 1 |
| 14 | Temperature variation of reaction liquid of ultrafine corn stover in photosynthetic hydrogen production显示文摘The thermo-physical phenomena existing in the process of hydrogen production by photosynthetic bacteria with ultrafine corn stover directly affect the energy consumption of biological hydrogen production system,the activity of hydrogen production,and hydrogen production rate.In order to discover theoretical basis for optimizing process parameters of the photosynthetic bioreactor for ultrafine corn stover,experimental investigation was conducted to identify the effects of the granularity of ultrafine corn stover on the temperature variation using a self-developed photosynthetic bio-hydrogen thermal-effect experimental device.This paper describes experimental research on temperature variation of reaction liquid with ultrafine-ground corn stover in photosynthetic hydrogen production,and on the temperature field and change trend of reaction liquid of corn stover with different granularities in bio-hydrogen production.Experimental results showed that,the greater the granularity of corn stover,the slower the temperature rising speed of the reaction liquid with corn stover in the initial phase of photosynthetic hydrogen production,and the lower the relative average temperature of reaction liquid in photosynthetic hydrogen production.This result is of great significance in research on the photosynthetic hydrogen production technology from biomass,providing a theoretical basis for thermal effect in solar photosynthetic hydrogen production. | Zhang Quanguo Wang Yingkuan Hu Jianjun Guo Jie Zhang Zhiping Jing Yanyan Xu Guangyin Wang Yi | 2014 | International Journal of Agricultural and Biological Engineering2014，7，5： | 1 |

| 16 | Tectonics and Seismicity of the Yarlung Tsangpo Grand Canyon Region显示文摘The Yarlung Tsangpo Grand Canyon region is located in the frontal zone of the eastern Himalayan syntaxis, where neo-tectonics and seismicity are intensive and closely related to each other. In the region, two sets of fault structures have developed, striking NNE-NE and NWW-NW, respectively. Investigation shows that they differ markedly in terms of scope, property, active times and intensity. The NWW-NW trending faults are large in size, and most are thrust and thrust strike-slip faults, formed in earlier times. The NEE-NE-strike faults are relatively small in size individually, with concentrated distribution, constituting the NNE-trending shear extensional fault zone, which is relatively younger with evident late Quaternary activities. Strong earthquakes occur mainly in the areas or zones of intensive differential movement of the Himalayas, e.g. along the deep and large fault zones around the crustal blocks. Most earthquakes of M≥7.0 are closely related to tectonics, where large-scale Holocene active faults are distributed with complicated fault geometry, or the faults of multiple directions intersect. Among them, earthquakes of M≥7.5 have occurred on the NW and NE-trending faults with a greater strike-slip component in the fault tectonic zones. | Shao Cuiru You Huichuan Cao Zhongquan Wang Chunyong Tang Fangtou Zhang Decheng Lou Hai Xu Guangyin Yang Qiyan Mei Tuo Xie Ping Yu Gang | 2009 | Earthquake Research in China2009，23，2： | 1 |

| 19 | The relative and combined effects of herbivore assemblage and soil nitrogen on plant diversity显示文摘Plant diversity can be affected by both herbivore grazing and soil resources. However, it is unclear if the joint effects of herbivores and soil resources might vary with components of plant diversity. Here, we evaluated the relative and combined effects of herbivore assemblage and soil nitrogen(N) quantity and heterogeneity on the α and β components of plant diversity in a grassland that was subjected to four years of grazing under differing herbivore assemblages(no grazing, cattle grazing, sheep grazing, and mixed grazing). We found that herbivore assemblage combined with soil N quantity explained 41% of the variation in plant α-diversity, while herbivore assemblage combined with soil N heterogeneity explained 15% of the variation in plant β-diversity. The independent effects of herbivore assemblage explained more than those of soil N for both α-and β-diversity(α-diversity: 12% vs. 4%;β-diversity: 18% vs. 16%). We concluded that the effects of herbivores are stronger than those of soil N,and that grazing-induced changes in soil resources are important drivers of plant diversity change, especially α-diversity.Therefore, we suggest that managing herbivore species by accounting for the effects that their grazing can have on soil resources may be significant for plant diversity maintenance. | Minna Zhang Bai Liu Guangyin Li Yingying Kuang Xiuquan Yue Shicheng Jiang Jushan Liu Ling Wang | 2022 | Science China(Life Sciences)2022，65，4： | 1 |
