| 1 | Main deposit styles and associated tectonics of the West Junggar region,NW China显示文摘The West Junggar region,located in the loci of the Central Asian Orogenic Belt,is a highly endowed metallogenic province with >100 tonnes Au,>0.7 Mt Cu,>0.3 Mt Mo,and >2.3 Mt chromite as well as significant amounts of Be and U.The West Junggar region has three metallogenic belts distributed systematically from north to south:(1) late Paleozoic Saur Au-Cu belt;(2) early Paleozoic XiemisitaiSharburt Be-U-Cu-Zn belt;(3) late Paleozoic Barluk-Kelamay Au-Cu-Mo-Cr belt.These belts host a number of deposits belonging to at least eight economically important styles,including epithermal Au,granite-related Be-U,volcanogenic massive sulfide(VMS) Cu-Zn,podiform chromite,porphyry Cu,hydrothermal quartz vein Au,porphyry-greisen Mo(-W),and orogenic Au.These deposit styles are associated with the tectonics prevalent during their formation.Five tectonic-mineralized epochs can be recognized:(1) Ordovician subduction-related VMS Cu-Zn deposit;(2) Devonian ophiolite-related podiform chromite deposit;(3) early Carboniferous subduction-related epithermal Au and porphyry Cu deposits;(4) late Carboniferous subduction-related granite-related Be-U,porphyry Cu,and hydrothermal quartz vein Au deposits;and(5) late Carboniferous to early Permian subduction-related porphyry-greisen Mo(-W) and orogenic Au deposits. | Ping Shen Hongdi Pan Yuanchao Shen Yuhong Yan Shihua Zhong | 2015 | Geoscience Frontiers2015，6，2： | 8 |
| 2 | T lymphocytes in the intestinal mucosa: defense and tolerance显示文摘Although lymphocytes are known to circulate throughout lymphoid tissues and blood,they also establish residency in nonlymphoid organs,most prominently in barrier tissues,such as the intestines.The adaptation of T lymphocytes to intestinal environments requires constant discrimination between natural stimulation from commensal flora and food and pathogens that need to be cleared.Genetic variations that cause a defective defense or a break in tolerance along with environmental cues,such as infection or imbalances in the gut microbiota known as dysbiosis,can trigger several immune disorders via the activation of T lymphocytes in the intestines.Elucidation of the immune mechanisms that distinguish between commensal flora and pathogenic organisms may reveal therapeutic targets for the prevention or modulation of inflammatory diseases and boost the efficacy of cancer immunotherapy.In this review,we discuss the development and adaptation of T lymphocytes in the intestine,how these cells protect the host against pathogenic infections while tolerating food antigens and commensal microbiota,and the potential implications of targeting these cells for disease management and therapeutics. | Hongdi Ma Wanyin Tao Shu Zhu | 2019 | Cellular & Molecular Immunology2019，16，3： | 6 |
| 3 | Enhanced wetting and properties of carbon/carbon-Cu composites with Cr_3C_2 coatings by Cr-solution immersion method显示文摘A facile ammonium-dichromate solution immersion method was introduced to synthesize the copperwettable Cr_3C_2 coating on and inside the carbon-carbon(C/C) preform. The formation mechanism and the microstructures of the Cr_3C_2 coatings were studied. The contact angle between molten copper and the C/C decreased from 140? to 60?, demonstrating the significant improvement in the wettability. The Cr_3C_2-coated C/C-Cu composite with only 4.2% porosity and 3.69 g cm^(-3) density was manufactured through copper infiltration. As a result, the thermal and electrical conductivity of the modified C/C-Cu increased significantly due to the infiltrated copper. Also the mechanical properties of the composites including both the flexural and compressive strengths were enhanced by over 100%. The modified C/C-Cu composite exhibited lower friction coefficients and wear rates for different load levels than those of the commercial C/Cu composite. These results demonstrate the potential of the modified C/C-Cu material for use in electrical contacts. | Bo Kong Jinming Ru Hongdi Zhang Tongxiang Fan | 2018 | Journal of Materials Science & Technology2018，34，3： | 4 |
| 4 | Crystallization and Corrosion Resistance of (Fe_(0.78)Si_(0.09)B_(0.13))100_(-x)Ni_x (x=0,2 and 5) Glassy Alloys显示文摘The crystallization of the (Fe0.78Si_(0.09)B0.13)100-xNix glassy alloys (x=0, 2 and 5) has been investigated by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). Corrosion resistance analyses have been carried out using electrochemical measurements and corrosion products have been analyzed by scanning electron microscopy (SEM). The experimental results show that the addition of Ni can promote the nucleation of α-Fe, retard the decomposition of the metastable borides, and alter the crystallization mode of the present Fe-based glassy alloys. The lattice constant (a0Fe) of α-Fe in the annealed samples shows a decreasing trend with increasing annealing time. The Ni addition can improve the corrosion resistance of the as-quenched Fe-based glassy alloys in H2SO4, NaCl and NaOH solutions. The results indicate that Ni can promote the diffusion of Si atoms during quenching and annealing processes. | Haitian Ma Weimin Wang die Zhang Guihua Li Chongde Cao Hongdi Zhang | 2011 | Journal of Materials Science & Technology2011，27，12： | 4 |

| 6 | Effect of doped strontium on catalytic properties of La_(1-x)SrxMnO_(3) for rhodamine B degradation显示文摘A series of La_(1-x)Sr_(x)MnO_(3) samples were prepared by sol-gel method and used to degrade rhodamine B(RhB) in water.All samples were characterized by X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),N_(2) adsorption-desorption,temperature-programmed reduction of H_(2)(H_(2)-TPR) and temperature-programmed desorption of O_(2)(O_(2)-TPD).The results show that the degradation of RhB is highly dependent on the initial pH value of solution.Sr doping enhances the degradation ability of LaMnO_(3) for RhB in the time range of 0-40 min under a strong acidic environment,but all samples exhibit similar degradation rate from 40 to 60 min.In La_(0.7)Sr_(0.3)MnO_(3)-RhB reaction system,there are two different degradation pathways,including N-de-ethylation,chromophore cleavage,ring-opening and mineralization.La_(1-x)Sr_(x)MnO_(3)(x ≤0.3) has the perovskite structure of La-Mn oxides,while La_(0.6)Sr_(0.4)MnO_(3) exhibits a Sr_(0.4)MnLa_(0.6)O_(2).98 perovskite phase.Sr doping leads to distortion of rhombohedral crystal structure and increases the relative content of Mn^(4+).The perovskite structure is stable in strong acidic environment during RhB degradation,but the relative content of Mn^(4+)and Mn^(3+) on the material surface changes.Sr doped LaMnO_(3) achieves specific surface area of 58.8 m^(2)/g and total pore volume of 0.152 cm^(3)/g.Furthermore,Sr^(2+)doping improves redox properties of La-Mn oxides,and the presence of defects makes oxygen diffusion easier compared with the undoped samples. | Jiaxiu Guo YueJing Ting Shen Hongdi Luo Juan Liang Shandong Yuan | 2021 | Journal of Rare Earths2021，39，11： | 2 |
| 7 | Formation of wormlike mi-celles in anionic surfactant AES aqueous solutions显示文摘The growth and structure of anionic micelles of sodium dodecyl trioxyethylene sulfate (AES) in the presence of multivalent counterion Al3+ were investigated by means of dynamic rheological methods. It has been obtained by themeasurements of shear viscosity, complex viscosity anddynamic moduli, as well as the application of Cox-Merz rule and Cole-Cole plot that wormlike micelle and networkstructure could be formed in AES/AlCl3 aqueous solutions. The structure was of a character of nonlinear viscoelasticfluid and departure from the simple Maxwell model. Thetechnique of freeze-fracture transmission electronmicroscopy (FF-TEM) was also used to confirm theformation of this interesting structure. | MU Jianhai LI Ganzuo XIAO Hongdi LIAO Guangzhi LIU Yi HUANG Li LI Boqin | 2001 | Chinese Science Bulletin2001，46，16： | 2 |
| 8 | Phase Transformation Strengthening of Hot Extruded Inconel 625 under High-temperature Load Environment显示文摘Microstructure evolution and properties of hot-extruded Inconel 625 alloy were investigated at different creep temperatures, aging time and strain rates. The experimental results indicate that the Inconel 625 alloy exhibits an excellent creep resistance at 700 ℃ and below. When the creep temperature rises to 750 ℃, the creep resistance falls drastically due to the failure of phase transformation strengthening and the precipitation of a large amount of δ phase and σ phase at the grain boundary. The special temperature-sensitive characteristics of Inconel 625 alloy play a very important role in its fracture. When the strain rate is 8.33×10^-3s^-1, the strength of the specimen is higher than that of other parameters attributed to the effect of phase transformation strengthening. With the increase of Ni3(Al, Ti), the phase transformation strengthening inhibits thickening of the stacking faults into twins and improves the overall mechanical properties of the alloy. With the increase of the aging time, the granular Cr-rich M23C6 carbides continue to precipitate at the grain boundary, which hinders the movement of the dislocations and obviously increases the strength of the samples. Especially, the yield strength increases several times. | 刘德学 CUI Maomao 王文旭 NAN Hongqiang CAI Haopeng XUE Hongdi JIA Zhi LI Qinglin | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，6： | 2 |

| 15 | Effect of Compression on the Crystallization Behavior and Corrosion Resistance of Al_(86)Ni_9La_5 Amorphous Alloy显示文摘The effect of compression on the crystallization behavior and corrosion resistance of Al(86)Ni9La5 amorphous ribbons was investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning elec-tron microscopy (SEM) and electrochemistry test. The XRD and TEM results reveal that the compressed Al(86)Ni9La5 ribbons spun with the circumferential speed (R) of 29.3 m/s are in fully amorphous state; however, the compressed ribbons spun with R=14.7 m/s have crystalline phases embedded in the amorphous matrix. The SEM images indicate that after compression, the toughness of the ribbons increases. Electrochemical results show that the compression decreases the stability of the passive film of the Al(86)Ni9La5 amorphous ribbons, because of the compression-introduced free volume, shear bands and crystalline phases; meanwhile, with R=14.7 m/s, the compression-induced crystalline phases in the Al(86)Ni9La5 ribbons increase the corrosion potential. | Yan Liu Weimin Wang Hongdi Zhang Haitian Ma Bang An | 2012 | Journal of Materials Science & Technology2012，28，12： | 1 |
