| 1 | Experimental research and numerical simulation of the multi-field performance of cemented paste backfill:Review and future perspectives显示文摘Cemented paste backfill(CPB)technology is a green mining method used to control underground goaves and tailings ponds.The curing process of CPB in the stope is the product of a thermo-hydro-mechanical-chemical multi-field performance interaction.At present,research on the multi-field performance of CPB mainly includes indoor similar simulation experiments,in-situ multi-field performance monitoring experiments,multi-field performance coupling model construction of CPB,and numerical simulation of the multi-field performance of CPB.Because it is hard to study the in-situ multi-field performance of CPB in the real stope,most current research on in-situ multi-field performance adopts the numerical simulation method.By simulating the conditions of CPB in the real stope(e.g.,maintenance environment,stope geometry,drainage conditions,and barricade and backfilling rates),the multi-field performance of CPB is further studied.This paper summarizes the mathematical models employed in the numerical simulation and lists the engineering application cases of numerical simulation in the in-situ multi-field performance of CPB.Finally,it proposes that the multi-field performance of CPB needs to strengthen the theoretical study of multi-field performance,form the strength design criterion based on the multi-field performance of CPB,perform a full-range numerical simulation of the multi-field performance of CPB,develop a pre-warning technology for the CPB safety of CPB,develop automatic and wireless sensors for the multi-field performance monitoring of CPB,and realize the application and popularization of CPB monitoring technology. | Yong Wang Zhenqi Wang Aixiang Wu Liang Wang Qing Na Chen Cao Gangfeng Yang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，2： | 2 |

| 4 | Water-dispersible nano-pollutions reshape microbial metabolism in type-specific manners:A metabolic and bacteriological investigation in Escherichia coli显示文摘Incomplete separation and recycling of nanoparticles are causing undesirable nanopollution and thus raising great concerns with regard to nanosafety.Since microorganisms are important regulator of physiological processes in many organisms,the interaction between nanopollution and microbial metabolomics and the resultant impact on the host’s health are important but unclear.To investigate how typical nanopollution perturbs microbial growth and metabolism,Escherichia coli(E.coli)in vitro was treated with six water-dispersible nanomaterials(nanoplastic,nanosilver,nano-TiO 2,nano-ZnO,semiconductor quantum dots(QDs),carbon dots(CDs))at human-/environment-relevant concentration levels.The nanomaterials exhibited type-specific toxic effects on E.coli growth.Global metabolite profiling was used to characterize metabolic disruption patterns in the model microorganism exposed to different nanopollutants.The percentage of significant metabolites(p<0.05,VIP>1)accounted for 6%–38%of the total 293 identified metabolites in each of the nanomaterial-contaminated bacterial groups.Metabolic results also exhibited significant differences between different nanopollutants and dose levels,revealing type-specific and untypical concentration-dependent metabolic responses.Key metabolites responsive to nanopollution exposures were mainly involved in amino acid and purine metabolisms,where 5,4,and 7 significant metabolic features were included in arginine and proline metabolism,phenylalanine metabolism,and purine metabolism,respectively.In conclusion,this study horizontally compared and demonstrated how typical nanopollution perturbs microbial growth and metabolomics in a type-specific manner,which broadens our understanding of the ecotoxicity of nanopollutants on microorganisms. | Shuqin Liu Rui Wu Xi Yang Shuting Fang Zhangmin Xiang Shenghong Yang Gangfeng Ouyang | 2022 | Frontiers of Environmental Science & Engineering2022，16，9： | 0 |
| 5 | Review and prospect of soil compound erosion显示文摘Soil erosion is one of the most serious environmental issues constraining the sustainable development of human society and economies.Soil compound erosion is the result of the alternation or interaction between two or more erosion forces.In recent years,fluctuations and extreme changes in climatic factors(air temperature,precipitation,wind speed,etc.)have led to an increase in the intensity and extent of compound erosion,which is increasingly considered in soil erosion research.First,depending on the involvement of gravity,compound erosion process can be divided into compound erosion with and without gravity.We systematically summarized the research on the mechanisms and processes of alternating or interacting soil erosion forces(wind,water,and freeze-thaw)considering different combinations,combed the characteristics of compound erosion in three typical regions,namely,high-elevation areas,high-latitude areas,and dry and wet transition regions,and reviewed soil compound erosion research methods,such as station observations,simulation experiments,prediction models,and artificial neural networks.The soil erosion model of wind,water,and freeze-thaw interaction is the most significant method for quantifying and predicting compound erosion.Furthermore,it is proposed that there are several issues such as unclear internal mechanisms,lack of comprehensive prediction models,and insufficient scale conversion methods in soil compound erosion research.It is also suggested that future soil compound erosion mechanism research should prioritize the coupling of compound erosion forces and climate change. | YANG Wenqian ZHANG Gangfeng YANG Huimin LIN Degen SHI Peijun | 2023 | Journal of Arid Land2023，15，9： | 0 |
| 6 | Fabrication of Porous Nanocrystalline NiCo_2O_4 Electrode for Water Electrolysis显示文摘A porous nanocrystalline NiCo_2O_4 compound electrode was obtained.The morphology of the electrode was controlled by altering the concentration of precipitant (NaOH solution).The electrode was consisted of metal substrate (Ni) and porous nanocrystalline NiCo_2O_4 film which was stacked by homosized and pretty regular hexagonal nanoparticles,with thinner than 50 nm and about 200 nm in diameter.The electrode exhibits good electrochemical properties compared with Ni electrode. | Jun Yang Xiaozhan Yang Jianbao Li Hong Lin Ning Wang Chunfu Lin Gangfeng Guo | 2006 | 稀有金属材料与工程2006，35，A03： | 0 |
| 7 | Statistical Characterization of the Yield Stress of Nanoparticles显示文摘Atomistic simulations are performed to study the statistical mechanical properties of gold nanoparticles.It is demonstrated that the yielding behavior of gold nanoparticles is governed by the dislocation nucleation around surface steps.Since the nucleation of dislocation is an activated process with the aid of thermal fluctuation,the yield stress at a specific temperature should vary statistically rather than being a definite constant value.Molecular dynamics simulations reveal that the yield stress follows a Gaussian distribution at a specific temperature.As the temperature increases,the mean value of yield stress decreases while the width of distribution becomes larger.Based on the numerical analysis,the dependence of mean yield stress on temperature can be well described by a parabolic function.This study illuminates the statistical features of the yielding behavior of nanostructured elements. | Liang Yang Jianjun Bian Weike Yuan Gangfeng Wang | 2021 | Acta Mechanica Solida Sinica2021，34，2： | 0 |
