| 1 | Effects of land-use and climate change on sediment and nutrient retention in Guizhou,China显示文摘Introduction:Sediment and nutrient retention have significant impacts on agricultural productivity and water quality.Obvious changes of climate and land-use have deeply affected freshwater ecosystem services in the last several decades.Nevertheless,it is unclear what the differences are in the impact of climate and land-use changes on freshwater ecosystem services.Outcomes:The impacts of climate and land-use change on sediment and nutrient retention(two essential freshwater ecosystem services)were evaluated with the help of the Integrated Valuation of Environmental Services and Tradeoffs(InVEST)model.The results from the study area suggest a decreasing trend in sediment and nutrient retention from 1995 to 2015 when climate and land-use were changed simultaneously.A decreasing trend in sediment retention and an increasing trend in nutrient retention were presented under scenario A(climate change from 1995 to 2015 with land-use unchanged),while the sediment exported and nutrient retention exhibited a decreasing trend except sediment retained under scenario B(land-use change from 1995 to 2015 with unchanged climate).Rainfall erosivity and soil erodibility were more sensitive to the output of sediment retention,while retention efficiency produced more of an effect on nutrient retention.Discussion and Conclusion:Climate change played a dominant role in the change in sediment retention,while land-use change had a more significant effect on nutrient retention change than climate change.The results of this study provide explicitinformation for land-use managers to reduce the negative effects associated with sediment and nutrient retention. | Huiqing Han Jianqiang Yang Geng Ma Yue Liu Linan Zhang Siying Chen Shuliang Ma | 2020 | Ecosystem Health and Sustainability2020，6，1： | 1 |

| 5 | One-step gas-phase construction of carbon-coated Fe3O4 nanoparticle/carbon nanotube composite with enhanced electrochemical energy storage显示文摘Carbon nanotubes(CNTs)as superior support materials for functional nanoparticles(NPs)have been widely demonstrated.Nevertheless,the homogeneous loading of these NPs is still frustrated due to the inert surface of CNTs.In this work,a facile gas-phase pyrolysis strategy that the mixture of ferrocene and CNTs are confined in an isolated reactor with rising temperature is developed to fabricate a carbon-coated Fe3O4 nanoparticle/carbon nanotube(Fe3O4@C/CNT)composite.It is found the ultra-small Fe3O4 NPs(<10 nm)enclosed in a thin carbon layer are uniformly anchored on the surface of CNTs.These structural benefits result in the excellent lithium-ion storage performances of the Fe3O4@C/CNT composite.It delivers a stable reversible capacity of 861 mA·h·g^-1 at the current density of 100 mA·g^-1 after 100 cycles.The capacity retention reaches as high as 54.5%even at 6000 mA·g^-1.The kinetic analysis indicates that the featured structural modification improves the surface condition of the CNT matrix,and contributes to greatly decreased interface impendence and faster charge transfer.In addition,the post-morphology observation of the tested sample further confirms the robustness of the Fe3O4@C/CNT configuration. | Yun ZHAO Linan YANG Canliang MA | 2020 | Frontiers of Materials Science2020，14，2： | 1 |
| 6 | Structural Design and Dynamic Characteristics of Overloaded Horizontal Servo Cylinder for Resisting Dynamic Partial Load显示文摘When an output curve force is applied to a horizontal servo cylinder with a heavy load, the piston rod bears a dynamic partial load based on the installation and load characteristics, which significantly a ects the frequency response and control accuracy of the servo cylinder. Based on this partial load, increased friction can lead to cylinder bore scu ng, leakage, lack of output power, or even system failure. In this paper, a novel asymmetric static-pressure support structure is proposed based on the principle of hydrostatic support. The radial component force of a dynamic partial load is balanced by cooperation between the support oil cushion of the variable hydraulic pressure support structure, oil cushion of the supportive force, and the damper. Adaptive control of the servo cylinder piston rod, guide sleeve, and piston, as well as the cylinder oil film friction between lubricated surfaces is achieved. In this paper, theoretical design and analysis of the traditional hydrostatic bearing structure and novel structure are presented. A hydraulic dynamic shear scissor is used as a research target to derive a structural dynamic model. Comparative simulations are performed using Matlab Simulink. Additionally, flow field analysis of the novel structure is performed, which verifies the rationality and feasibility of the proposed structure and system. | Linan Ma Qingxue Huang Lifeng Ma Qiangjun Ma Wenze Zhang Heyong Han | 2019 | Chinese Journal of Mechanical Engineering2019，32，1： | 0 |
| 7 | Ca^2+ doping effects in(K,Na,Li)(Nb0.8Ta0.2)O3 lead-free piezoelectric ceramics显示文摘Lead-free(K0.5-x/2Na0.5-x/2Lix)(Nb0.8Ta0.2)O3(KNLNT)and(K0.49-x/2Na0.49-x/2-LixCa0.01)(Nb0.8Ta0.2)O3(KNLNT-Ca)ceramics were prepared by a conventional ceramic processing.Structural analysis shows that the Ca^2+ doping takes the A site of ABO3 perovskite and decreases the phase transition temperature.Property measurements reveal that as a donor dopant,the Ca^2+ doping results in higher room-temperature dielectric constant,lower dielectric loss,and lower mechanical quality factor.In addition,the Ca^2+ doping does not change the positive piezoelectric coefficient d33,but increases the converse piezoelectric coefficient d 33*significantly.This is likely due to the increase in the relaxation,as well as the appearance of(CaNa/K·-VNa/K’)defect dipoles. | Lei TANG Tengfei LIU Jinxu MA Xiaowen ZHANG Linan AN Kepi CHEN | 2019 | Frontiers of Materials Science2019，13，4： | 0 |
