1Spatio-temporal variation of vegetation in an arid and vulnerable coal mining region显示文摘Environmental assessment in an arid coal mining area requires an understanding of the influences of coal mining,the arid climate and ecological remediation.To that end,we selected vegetation as the key environmental factor to observe.Remote sensing approaches to monitoring the spatio-temporal variation of vegetation caused by mining activities,the arid climate and ecological remediation in the Shengdong coal mining area are described.Over a large regional scale it was found that the vegetation was improved as a result of ecological remediation activities.At the local scale,however,the vegetation coverage and soil moisture in the mined areas were slightly lower than those in un-mined areas due to mining subsidence.These differences are partly attributed to ground fissures that injure root systems and increase the depletion of soil moisture.It is recommended that fissures be reduced and filled to lessen their adverse effects on the environment.LEI Shaogang BIAN Zhengfu DANIELS John L HE Xiao 2010Mining Science and Technology2010,20,3:20
2Mechanism of formation of sliding ground fissure in loess hilly areas caused by underground mining显示文摘Based on a shallow-buried coal seam covered with thick loose layers in hilly loess areas of western China,we developed a mechanical model for a mining slope with slope stability analysis, and studied the mechanism of formation and development of a sliding ground fissure by the circular sliding slice method.Moreover, we established a prediction model of a sliding fissure based on a mechanical mechanism,and verified its reliability on face 52,304, an engineering example, situated at Daliuta coal mine of Shendong mining area in western China. The results show that the stress state of a mining slope is changed by its gravity and additional stress from the shallow-buried coal seam and gully terrain. The mining slope is found to be most unstable when the ratio of the down-sliding to anti-sliding force is the maximum, causing local fractures and sliding fissures. The predicted angles for the sliding fissure of face 52,304 on both sides of the slope are found to be 64.2° and 82.4°, which are in agreement with the experimental data.Liu Hui Deng Kazhong Lei Shaogang Bian Zhengfu 2015International Journal of Mining Science and Technology2015,25,4:10
3Electron 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
4Effect of ferric and bromide ions on the formation and speciation of disinfection byproducts during chlorination显示文摘The effects of ferric ion, pH, and bromide on the formation and distribution of disinfection byproducts (DBPs) during chlorination were studied. Two raw water samples from Huangpu River and Yangtze River, two typical drinking water sources of Shanghai, were used for the investigation. Compared with the samples from Huangpu River, the raw water samples from Yangtze River had lower content of total organic carbon (TOC) and ferric ions, but higher bromide concentrations. Under controlled chlorination conditions, four trihalomethanes (THMs), nine haloacetic acids (HAAs), total organic halogen (TOX) and its halogen species fractions, including total organic chlorine (TOCl) and total organic bromide (TOBr), were determined. The results showed that co-existent ferric and bromide ions significantly promoted the formation of total THMs and HAAs for both raw water samples. Higher concentration of bromide ions significantly changed the speciation of the formed THMs and HAAs. There was an obvious shift to brominated species, which might result in a more adverse influence on the safety of drinking water. The results also indicated that high levels of bromide ions in raw water samples produced higher percentages of unknown TOBr.Shaogang Liu Zhiliang Zhu Yanling Qiu Jianfu Zhao 2011Journal of Environmental Sciences2011,23,5:9
5How 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
6Seasonal variation effects on the formation of trihalomethane during chlorination of water from Yangtze River and associated cancer risk assessment显示文摘For the system of water samples collected from Yangtze River,the effects of seasonal variation and Fe(III) concentrations on the formation and distribution of trihalomethanes (THMs) during chlorination have been investigated.The corresponding lifetime cancer risk of the formed THMs to human beings was estimated using the parameters and procedure issued by the US EPA.The results indicated that the average concentration of THMs (100.81 μg/L) in spring was significantly higher than that in other seasons,which was related to the higher bromide ion concentration resulted from the intrusion of tidal saltwater.The total cancer risk in spring reached 8.23 × 10 ?5 and 8.86 × 10 ?5 for males and females,respectively,which were about two times of those in summer under the experimental conditions.Furthermore,it was found that the presence of Fe(III) resulted in the increased level of THMs and greater cancer risk from exposure to humans.Under weak basic conditions,about 10% of the increment of THMs from the water samples in spring was found in the presence of 0.5 mg/L Fe(III) compared with the situation without Fe(III).More attention should be given to the effect of the coexistence of Fe(III) and bromide ions on the risk assessment of human intake of THMs from drinking water should be paid more attention,especially in the coastland and estuaries.Shaogang Liu Zhiliang Zhu Chenfeng Fan Yanling Qiu Jianfu Zhao 2011Journal of Environmental Sciences2011,23,9:6
7Peripheral Lymphocyte Subsets as a Marker of Parkinson's Disease in a Chinese Population显示文摘In this study, we conducted a clinical analysis of lymphocyte subtypes in 268 patients with Parkinson's disease(PD) to assess their clinical impact as a potential marker of advanced PD in Chinese patients. The participants comprised 268 sporadic PD patients and 268 healthy controls. The numbers of natural killer(NK) cells and CD3+, CD3+CD4+, CD3+CD8+, and CD19+ lymphocytes from peripheral blood were determined by immunostaining and flow cytometric analysis and the percentages of these CD+ T cells were calculated. The ratio of regulatory T(Treg)/helper T 17(Th17) lymphocytes from 64 PD patients and 46 controls was determined by flow cytometric analysis.The results showed that the percentage of NK cells was higher in advanced PD patients than in controls(22.92% ±10.08% versus 19.76% ± 10.09%, P = 0.006), while CD3+ T cells are decreased(62.93% ± 9.27% versus65.75% ± 9.13%, P = 0.005). The percentage of CD19+B cells in male patients was lower(P = 0.021) than in female patients, whereas NK cells were increased(P \ 0.0001). The scores on the Unified Parkinson's Disease Rating Scale(UPDRS) and the Non-Motor Symptoms Scale in late-onset PD patients were significantly higher than those in earlyonset patients(P = 0.024 and P = 0.007, respectively). The percentage of CD19+ B cells in patients with UPDRS scores[24 was lower than in those with scores \24(10.17% ±4.19% versus 12.22% ± 5.39%, P = 0.009). In addition, the Treg/Th17 ratio in female patients was higher than that in female controls(13.88 ± 6.32 versus 9.94 ± 4.06, P =0.042). These results suggest that the percentages of NK cells,CD3+ T cells, and CD19+ B cells along with the Treg/Th17 ratio in peripheral blood may be used to predict the risk of PD in Chinese individuals and provide fresh avenues for novel diagnostic biomarkers and therapeutic designs.Luan Cen Chaohao Yang Shuxuan Huang Miaomiao Zhou Xiaolu Tang Kaiping Li Wenyuan Guo Zhuohua Wu Mingshu Mo Yousheng Xiao Xiang Chen Xinling Yang Qinhui Huang Chaojun Chen Shaogang Qu Pingyi Xu 2017Neuroscience Bulletin2017,33,5:5
8Spatio-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
9Investigating 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
10Ice-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

14Effects 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

16Evolution 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

18Efficient 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
