| 2 | A Preliminary Review on the Metallogeny of Pb-Zn Deposits in China显示文摘Lead and zinc resources are abundant in China, with the reserves of 100 million tons ranking only second in the world. There are more than 3000 lead-zinc mine areas nationwide. The classification of lead-zinc(Pb-Zn) deposits has been a highly controversial issue. From the standpoint of evaluating the potential of mineral resources, we construct a Pb-Zn deposit predictive type of classification scheme, and propose a Pb-Zn deposit comprehensive classification scheme(including 5 classes and 13 sub-types) that regards mineralization as the primary factor and the ore rock as secondary. According to the temporal and spatial distribution of Pb-Zn deposits, we conclude that a multi-period, multi-cycle orogenic environment is the most favorable for lead-zinc deposit growth, that the Proterozoic is the major eon for the growth of igneous-type deposits, the Paleozoic is an important development era for sedimentary Pb-Zn deposits, and the Mesozoic and Cenozoic are the heyday eras of magmatic type lead-zinc deposits. On this basis, we analyse the relationship between tectonic evolution and Pb-Zn metallogenic, and propose that the key factors determining geological mineralization are the metallogenic epoch of mineralization and tectonic environment, which determine the temporal and spatial distribution. | ZHANG Changqing LIU Huan WANG Denghong CHEN Yuchuan RUI Zongyao LOU Debo WU Yue JIA Fudong CHEN Zhenghui MENG Xuyang | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 1 |

| 4 | Microstructure,mechanical and fracture properties of friction stir welded 2195 Al-Li alloy joints显示文摘The 8 mm-thick 2195 Al-Li alloy joints were achieved by Friction Stir Welding(FSW).The microstructural evolution,temperature-dependent mechanical properties,and fracture properties were studied.The T1,δ’/β’and θ’precipitates were observed in the Base Metal(BM)and the Heat Affected Zone(HAZ).Most of the precipitates,except for re-precipitated δ’/β’phases,were dissolved in the Nugget Zone(NZ).The tensile specimens that failed at cryogenic temperatures(-196℃)had the maximum Ultimate Tensile Strength(UTS),and the fracture surface showed the inter-granular fracture characteristics.Compared to those at room temperature(25℃),the decreasing tensile properties at high temperature(180℃)were related to microstructure and strain hardening effects.The NZ presented the optimal fracture toughness,and the Crack Tip Opening Displacement(CTOD)was mutually dominated by microhardness and grain size.Analysis on Fatigue Crack Growth(FCG)rates indicates that the Thermal-Mechanically Affected Zone(TMAZ)exhibited the most superior fatigue resistance performance at stress intensity range below17 MPa.m1/2due to compressive residual stress and the crack closure effect.The fatigue fracture surfaces reveal that the crack propagation zone was characterized by the striations and secondary cracks.Also,inter-granular fracture behavior was responsible for the fastest FCG rates in the NZ. | Guangda SUN Weizhao SUN Li ZHOU Sanfeng LUO Zili ZHANG Debo LIU Huiqiang WU | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
| 5 | Vegetation Changes in Alberta Oil Sands,Canada,Based on Remotely Sensed Data from 1995 to 2020显示文摘There are rich oil and gas resources in Alberta oil sand mining area in Canada.Since the 1960s,the Canadian government decided to increase the mining intensity.However,the exploitation will bring many adverse effects.In recent years,more people pay attention to the environmental protection and ecological restoration of mining area,such as issues related with changes of vegetated lands.Thus,the authors used the Landsat-5 TM and Landsat-8 OLI remote sensing images as the basic data sources,and obtained the land cover classification maps from 1995 to 2020 by ENVI.Based on the NDVI,NDMI and RVI,three images in each period are processed and output to explore the long-term impact of exploitation.The results show that from 1995 to 2020,the proportion of vegetation around mining areas decreased sharply,the scale of construction land in the mining area increased,and the vegetated land was changed to land types such as tailings pond,oil sand mine and other land types.In addition,three vegetation indexes decreased from 1995 to 2020.Although the exploitation of oil sand mining area brings great economic benefits,the environmental protection(especially vegetation)in oil sand mining areas should be paid more attention. | Jinxin He Debo Chen Ye Zhan Chao Liu Ruichen Liu | 2022 | Journal of Environmental & Earth Sciences2022，4，2： | 0 |
| 6 | Multi-branched AgAuPt nanoparticles for efficient electrocatalytic hydrogen evolution:Synergism of tip-enhanced electric field effect and local electric field effect显示文摘High-curvature multi-noble metallic heterostructures can effectively enhance the electrocatalytic hydrogen evolution performance by utilizing the synergism of tip-enhanced electric field effect and local electric field effect.Herein,we report a two-step synthesis strategy to obtain multi-branched high-curvature Ag Au Pt heterostructure,firstly amino acids-induced growth of Au branches on Ag nanocubes,and secondly L-AA reduction of H_(2)PtCl_(6) to incorporate tiny Pt nanoparticles on Au branches.The D-CAgAuPt results in a low overpotential of 38 m V to deliver a cathodic current density of 10 m A cm^(-2),which is superior to commercial 20%Pt/C(46 m V).The strong electronic interactions between multi-noble metals intrinsically enhance the durability and stability of the catalysts.The intrinsic mechanism of promoting HER performance is investigated and revealed in-depth via the FDTD simulations and DFT calculations.In addition,D-CAg Au Pt can also achieve efficient and stable hydrogen evolution in a proton exchange membrane electrolyzer,which has the potential for commercial practical application.This work designs a novel multi-branched high-curvature multi-noble metallic heterostructure,and fully provides insights into the generical and efficient enhancement of electrocatalytic HER performance of multi-noble metallic heterostructures. | Wenliang Liu Xiaohan Li Yuqi Wang Debo Yang Zongzhen Guo Mengfei Liu Jiqian Wang | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
