1Electron Beam Melted Beta-type Ti–24Nb–4Zr–8Sn Porous Structures With High Strength-to-Modulus Ratio显示文摘Electron beam melting(EBM)has been used to manufactureβ-type Ti–24Nb–4Zr–8Sn porous components with 70%porosity.EBM-produced components have favorable structural features(i.e.smooth strut surfaces,fewer defects)and an(α+β)-type microstructure,similar to that subjected to aging treatment.EBM-produced components exhibit more than twice the strength-to-modulus ratio of porous Ti–6Al–4V components having the same porosity.The processing–microstructure–property relationship and deformation behavior of EBM-produced components are discussed in detail.Such porous titanium components composed of non-toxic elements and having high strength-to-modulus ratio are highly attractive for biomedical applications.Yujing Liu Shujun Li Wentao Hou Shaogang Wang Yulin Hao Rui Yang Timothy B.Sercombe Lai-Chang Zhang 2016Journal of Materials Science & Technology2016,32,6:9
2How do Chinese medicines that tonify the kidney inhibit dopaminergic neuron apoptosis?显示文摘Wistar rats were intragastrically perfused with Chinese medicines used for tonifying the kidney.These included 0.180 g/mL of Herba Epimedii(Epimedium), Semen Cuscutae(Dodder Seed), or Herba Cistanches(Desertliving Cistanche), 0.04 mg/mL monoamine oxidase-B inhibitor selegiline,or distilled water for 14 consecutive days to prepare drug-containing serum or blank serum.MES23.5 cells in the logarithmic phase were cultured in media supplemented with 15%drug-containing serum for 24 hours, followed by incubation in culture solution containing 100 μmol/L H2O2for 3 hours. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) and flow cytometry results showed that all drug-containing serums improved the survival rate of H2O2-injured MES23.5 cells, inhibited pro-apoptotic FasL and caspase-3 expression, promoted anti-apoptotic Bcl-2 expression. However, drug-containing serums had little influence on Fas expression in H2O2-injured MES23.5 cells. Enzyme-linked immunosorbent assay results showed that serum containing Herba Cistanches or Herba Epimedii increased the expression of nerve growth factor,brain-derived neurotrophic factor, and glial cell line-derived neurotrophic factor in injured MES23.5cells; serum containing Semen Cuscutae only increased brain-derived neurotrophic factor expression; while expression of the above neurotrophic factors remained the same in cells treated with serum containing selegiline. These findings indicate that Chinese medicines used to tonify the kidney can protect nerve cells by regulating the expression of apoptosis-related factors and neurotrophic factors in MES23.5 cells.Shaogang Lin Shuifen Ye Jinmu Huang Yun Tian Yihui Xu Mengqi Wu Jingxia Wang Songying Wu Jing Cai 2013Neural Regeneration Research2013,8,30:9
3Spatio-temporal dynamics of vegetation in Jungar Banner of China during 2000–2017显示文摘It is known that the exploitation of opencast coal mines has seriously damaged the environments in the semi-arid areas.Vegetation status can reliably reflect the ecological degeneration and restoration in the opencast mining areas in the semi-arid areas.Long-time series MODIS NDVI data are widely used to simulate the vegetation cover to reflect the disturbance and restoration of local ecosystems.In this study, both qualitative(linear regression method and coefficient of variation(CoV)) and quantitative(spatial buffer analysis, and change amplitude and the rate of change in the average NDVI) analyses were conducted to analyze the spatio-temporal dynamics of vegetation during 2000–2017 in Jungar Banner of Inner Mongolia Autonomous Region, China, at the large(Jungar Banner and three mine groups) and small(three types of functional areas: opencast coal mining excavation areas, reclamation areas and natural areas) scales.The results show that the rates of change in the average NDVI in the reclamation areas(20%–60%) and opencast coal mining excavation areas(10%–20%) were considerably higher than that in the natural areas(<7%).The vegetation in the reclamation areas experienced a trend of increase(3–5 a after reclamation)-decrease(the sixth year of reclamation)-stability.The vegetation in Jungar Banner has a spatial heterogeneity under the influences of mining and reclamation activities.The ratio of vegetation improvement area to vegetation degradation area in the west, southwest and east mine groups during 2000–2017 was 8:1, 20:1 and 33:1, respectively.The regions with the high CoV of NDVI above 0.45 were mainly distributed around the opencast coal mining excavation areas, and the regions with the CoV of NDVI above 0.25 were mostly located in areas with low(28.8%) and medium-low(10.2%) vegetation cover.The average disturbance distances of mining activities on vegetation in the three mine groups(west, southwest and east) were 800, 800 and 1000 m, respectively.The greater the scale of mining, the farther the disturbance distances of mining activities on vegetation.We conclude that vegetation reclamation will certainly compensate for the negative impacts of opencast coal mining activities on vegetation.Sufficient attention should be paid to the proportional allocation of plant species(herbs and shrubs) in the reclamation areas, and the restored vegetation in these areas needs to be protected for more than 6 a.Then, as the repair time increased, the vegetation condition of the reclamation areas would exceed that of the natural areas.LI Xinhui LEI Shaogang CHENG Wei LIU Feng WANG Weizhong 2019Journal of Arid Land2019,11,6:5
4Investigating spatial and temporal variations of soil moisture content in an arid mining area using an improved thermal inertia model显示文摘Mining operations can usually lead to environmental deteriorations. Underground mining activities could cause an extensive decrease in groundwater level and thus a dramatic variation in soil moisture content(SMC). In this study, the spatial and temporal variations of SMC from 2001 to 2015 at two spatial scales(i.e., the Shendong coal mining area and the Daliuta Coal Mine) were analyzed using an improved thermal inertia model with a long-term series of Landsat TM/OLI(TM=Thematic Mapper and OLI=Operational Land Imager) data. Our results show that at large spatial scale(the Shendong coal mining area), underground mining activities had insignificant negative impacts on SMC and that at small spatial scale(the Daliuta Coal Mine), underground mining activities had significant negative impacts on SMC. Trend analysis of SMC demonstrated that areas with decreasing trend of SMC were mainly distributed in the mined area, indicating that underground mining is a primary cause for the drying trend in the mining region in this arid environment.WANG Yuchen BIAN Zhengfu LEI Shaogang ZHANG Yu 2017Journal of Arid Land2017,9,5:5
5Ice-templated porous tungsten and tungsten carbide inspired by natural wood显示文摘The structures of tungsten and tungsten carbide scaffolds play a key role in determining the properties of their infiltrated composites for multifunctional applications.However,it is challenging to construct and control the architectures by means of self-assembly in W/WC systems because of their large densities.Here we present the development of unidirectionally porous architectures,with high porosities exceeding 65 vol.%,for W and WC scaffolds which in many respects reproduce the design motif of natural wood using a direct ice-templating technique.This was achieved by adjusting the viscosities of suspensions to retard sedimentation during freezing.The processing,structural characteristics and mechanical properties of the resulting scaffolds were investigated with the correlations between them explored.Quantitative relationships were established to describe their strengths based on the mechanics of cellular solids by taking into account both inter-and intra-lamellar pores.The fracture mechanisms were also identified,especially in light of the porosity.This study extends the effectiveness of the ice-templating technique for systems with large densities or particle sizes.It further provides preforms for developing new natureinspired multifunctional materials,as represented by W/WC-Cu composites.Yuan Zhang Guoqi Tan Da Jiao Jian Zhang Shaogang Wang Feng Liu Zengqian Liu Longchao Zhuo Zhefeng Zhang Sylvain Deville Robert O.Ritchie 2020Journal of Materials Science & Technology2020,42,10:4

8Effects of different aging treatments on microstructures and mechanical properties of Al-Cu-Li alloy joints welded by electron beam welding显示文摘Post-weld single aging treatment(solution treatment at 510 ℃ for 1 h, water quenching,and aging at 155 ℃ for 16 h) and post-weld double aging treatment(solution treatment at 510 ℃ for 1 h, water quenching, aging at 155 ℃ for 16 h, and aging at 130 ℃ for 12 h) are carried out on Al-Cu-Li alloy joints by electron beam welding(EBW) respectively. The effects of aging treatments on microstructures and mechanical properties of welded joints are investigated. Results show that the mechanical properties of welded joints are obviously improved after both aging treatments. The strength coefficient of joints is increased from 0.64 in an as-welded condition(AW) to 0.90 after post-weld double aging treatment. Microstructure analysis shows that the precipitates of the fusion zone within grains and grain boundaries are less in the AW condition. After post-weld heat treatment(PWHT), a lot of fine needle-like phases T_1(Al_2 Cu Li) precipitate in grain boundaries of the fusion zone, and more horseshoe-shaped β' (Al_3 Zr) particles precipitate within grains. In addition,grains of the fusion zone are refined after post-weld double aging treatment, which leads to an effect of grain refinement strengthening. Consequently, the mechanical properties of welded joints are greatly improved.Shaogang WANG Yan HUANG Li ZHAO 2018Chinese Journal of Aeronautics2018,31,2:3

10Evolution of micro-pores in a single crystal nickel-based superalloy during 980℃ creep显示文摘The evolution of micro-pores in a single crystal nickel-based superalloy during creep at 980 ℃/220 MPa was investigated by X-ray computed tomography. Time-dependent ex-situ 3D information including the number, volume fraction, distribution and morphology of micro-pores was analyzed. The results reveal that the signifi cant formation and growth of micro-pores occur at the end of secondary/beginning of tertiary creep stage. The irregular large pores as well as high density pores located at strain concentration region are the major detrimental factors facilitating the creep damage. Creep failure is resulted from the connection of surface cracks induced by oxidation, and the internal cracks generated from growth and merging of micro-pores.Yufeng He Shaogang Wang Jian Shen Dong Wang Yuzhang Lu Langhong Lou Jian Zhang 2022Acta Metallurgica Sinica(English Letters)2022,35,8:2
11Efficient polysulfide blocker from conductive niobium nitride@graphene for Li-S batteries显示文摘Lithium sulfur batteries are one of the most promising alternative electrochemical systems,but their practical applications are largely hindered by the serious shuttling problems and sluggish redox kinetics.Here,the conductive and polar niobium nitride(NbN)is in-situ introduced onto graphene with ultrasmall size and high dispersion,and their composite is used to construct an efficient lithium polysulfide blocking layer.The graphene helps to construct highly conductive pathways,and niobium nitride serves as the sulfiphilic sites to chemically adsorb the migrating lithium polysulfides and catalyze their redox conversion.Hence,the cells with the Nb N/G interlayers exhibit a long cycle life with a lower capacity decay of 0.096%/cycle at 1 C for 300 cycles and high rate capability of 937 m Ah g^-1 at 2 C.Further coupling with a sulfur/carbon nanofiber electrode,the cell with an ultra-high sulfur loading of 10.8 mg cm^-2 delivers an areal capacity of 12.5 m Ah cm^-2 at 0.1 C.Huifa Shi Zhenhua Sun Wei Lv Shujie Xiao Huicong Yang Ying Shi Ke Chen Shaogang Wang Bingsen Zhang Quan-Hong Yang Feng Li 2020Journal of Energy Chemistry2020,29,6:1

19Wear-resistant Ag-MAX phase 3D interpenetrating-phase composites:Processing,structure,and properties显示文摘Electrical contact materials are generally Ag-or Cu-based composites and play a critical role in ensuring the reliability and efficiency of electrical equipments and electronic instruments.The MAX(M is an early transition metal,A is an element from III or IV main groups,and X is carbon or/and nitrogen)phase ceramics display a unique combination of properties and may serve as an ideal reinforcement phase for electrical contact materials.The biological materials evolved in nature generally exhibit three-dimensional(3D)interpenetrating-phase architectures,which may offer useful inspiration for the architectural design of electrical contact materials.Here,a series of bi-continuous Ag-Ti_(3)SiC_(2) MAX phase composites with high ceramic contents exceeding 50 vol.%and having micron-and ultrafine-scaled 3D interpenetrating-phase architectures,wherein both constituents were continuous and mutually interspersed,were exploited by pressureless infiltration of Ag melt into partially sintered Ti_(3)SiC_(2) scaffolds.The mechanical and electrical properties as well as the friction and wear performance of the composites were investigated and revealed to be closely dependent on the ceramic contents and characteristic structural dimensions.The composites exhibited a good combination of properties with high hardness over 2.3 GPa,high flexural strength exceeding 530 MPa,decent fracture toughness over 10 MPa·m^(1/2),and good wear resistance with low wear rate at an order of 10^(-5)mm^(3)/(N·m),which were much superior compared to the counterparts made by powder metallurgy methods.In particular,the hardness,electrical conductivity,strength,and fracture toughness of the composites demonstrated a simultaneous improvement as the structure was refined from micron-to ultrafine-scales at equivalent ceramic contents.The good combination of properties along with the facile processing route makes the Ag-Ti_(3)SiC_(2)3D interpenetrating-phase composites appealing for electrical contact applications.Yu Guo Xi Xie Zengqian Liu Longchao Zhuo Jian Zhang Shaogang Wang Qiqiang Duan Qing Jia Dake Xu Weihai Xue Deli Duan Filippo Berto Zhefeng Zhang Rui Yang 2024Nano Research2024,17,2:1
