Accurate knowledge of the kinematics of the in vivo Ankle Joint Complex(AJC)is critical for understanding the biomechanical function of the foot and assessing postoperative rehabilitation of ankle disorders,as well as an essential guide to the design of ankle–foot assistant devices.However,detailed analysis of the continuous 3D motion of the tibiotalar and subtalar joints during normal walking throughout the stance phase is still considered to be lacking.In this study,dynamic radiographs of the hindfoot were acquired from eight subjects during normal walking.Natural motions with six Degrees of Freedom(DOF)and the coupled patterns of the two joints were analyzed.It was found that the movements of the two joints were mostly in opposite directions(including rotation and translation),mainly in the early and late stages.There were significant differences in the Range of Motion(ROM)in Dorsiflexion/Plantarflexion(D/P),Inversion/Eversion(In/Ev),and Anterior–Posterior(AP)and Medial–Lateral(ML)translation of the tibiotalar and subtalar joints(p<0.05).Plantarflexion of the tibiotalar joint was coupled with eversion and posterior translation of the subtalar joint during the impact phase(R^(2)=0.87 and 0.86,respectively),and plantarflexion of the tibiotalar joint was coupled with inversion and anterior translation of the subtalar joint during the push-off phase(R^(2)=0.93 and 0.75,respectively).This coordinated coupled motion of the two joints may be a manifestation of the AJC to move flexibly while bearing weight and still have stability.

A facile and efficient ball-milling assisted sol-gel synthesis route was developed to prepare triclinic e-LiVOPO_(4)(LVOP)material with lanthanum(La)and cerium(Ce)modification individually as well as simultaneously.An LVOP/LaPO_(4)/CePO_(4)composite cathode material was successfully synthesized and results show that La and Ce co-modification noticeably improves the electrochemical performance by enhancing the high voltage capacity upon cycling,which indicates contributions from the good ionic conductors LaPO_(4)and CePO_(4).The simultaneous La and Ce modification improves the high voltage performance significantly with an increase of 50%in high voltage capacity after 20 cycles compared to pure LVOP.It also shows stabilized cycling perfo rmance with 91%capacity rete ntion after 50 cycles at 0.1 C rate,along with high-rate capability with a capacity of 83.1 mAh/g compared to the pristine sample showing the capacity of 51.6 mAh/g at a high rate of 5C.This can be attributed to the good conductivity of LaPO_(4)and CePO_(4).In addition,the LVOP/LaPO_(4)/CePO_(4)composite and the pristine LVOP give a charge transfer resistance of-105 and-212Ω,respectively,showing much lower impedance due to a combination of La and Ce addition.

The traditional bionic upper limb structure design is limited by the motion pair and cannot guarantee the flexibility of the mechanical structure.The tensegrity structure has the characteristics of high deformability,strong self-adaptability,and resistance to multi-directional impact.According to the biological characteristics of the upper limbs of the human body,an anatomical study is performed on the upper limb wrist joints that achieve adduction/abduction,flexion/extension,to obtain the relationship between the movements of the related bones and muscles,and to simplify the shape and structure of the wrist.Equivalent mapping of a mechanical model based on two-bar tensile properties.Through the contraction and stretching of the spring,the movement characteristics of the human muscles are realised,and the optimised bionic upper limb wrist tensioning robot without motion pair is further obtained.Adams simulation is used to verify that the bionic tensile wrist can simulate the change movement of the human wrist.The experimental platform was built and a physical prototype was made and the prototype was tested.The results show that the bionic tensile wrist can realise the adaptive motion characteristics of the human wrist well and stably,which proves the validity and feasibility of this design method.

SiO负极虽具有高比容量、合理的工作电压,但仍面临首次库仑效率低、体积膨胀大(~160%)及导电性差等硅基负极材料共性问题,使其在锂离子电池(LIBs)中的大规模商业化应用严重受阻。而在众多金属氧化物中,钛氧化物负极因在充放电过程中体积变化小(<4%),锂化后兼具优异的锂存储能力和热稳定性等优势,近些年被多次报道用于改善SiO的电化学综合性能。首先,从SiO的微观结构与锂化机制出发,简要概括了SiO与众多金属氧化物复合改性案例;然后,重点综述了钛氧化物改性SiO负极的研究工作,着重从TiO_(2)与TiO_(2–x)改性SiO负极两方面进行归纳与分析;最后,总结了钛氧化物提高SiO电化学性能的机理及改性工艺与电化学性能之间的构效关系,并对实现满足高能量密度SiO基负极商业化的目标进行展望:充分利用有关软件算法模拟具有最低化学复杂性体系,有利于深入分析反应过程与电化学机理;加强新型低成本钛氧化物(如Ti_(2)O_(3))用于改性SiO负极,有利于推动SiO基负极学术探究与商业应用。

Journal of Energy Chemistry 2018年第1期27卷 250-263页

作者： Md.Arafat Rahman Yat Choy Wong guangsheng song De Ming Zhu Cuie Wen Faculty of Science Engineering and TechnologySwinburne University of Technology Department of Mechanical Engineering Chittagong University of Engineering and Technology School of Material Science&Engineering Anhui University of Technology School of Engineering RMIT University

The effect of annealing of Ti foils before anodization on the morphology and electrochemical performance of resultant nanoporous anatase TiO2 （np-TiO2） as anode in rechargeable lithium-ion batteries （LIBs） was investigated. The np-TiO2 anode fabricated from annealed Ti foils exhibited higher specific surface area and reduced pore diameter compared to np-TiO2 electrode fabricated from as-received Ti foils. The highly porous np-TiO2 anode fabricated from annealed Ti foils exhibited 1st discharge capacity of 453.25 mAh/g and reduced to 172.70 mAh/g at 1 C current rate after 300 cycles; whilst the np-TiO2 electrode fabricated from the as-received Ti foils exhibited 1st discharge capacity of 213.30 mAh/g and reduced to 160.0 mAh/g at 1 C current rate after 300cycles. Even after 400cycles, such np-TiO2 electrode exhibited a reversible capacity of 125.0 mAh/g at 2.5 C current rate. Compared to the untreated Ti foils, the enhanced electro- chemical performance of np-TiO2 anode fabricated from annealed Ti foils was ascribed to the annealing- induced removal of residual stress among the Ti atoms. The benefit of annealing process can reduce pore size of as-fabricated np-TiO2.

将微米Si和纳米Ag_(2)O进行机械球磨,通过原位固相反应合成了Si基复合材料[Si/(SiO+Ag)],以沥青为碳源采用高温煅烧法制备了碳包覆Si基复合材料[Si/(SiO+Ag)-C]。采用XRD、XPS、SEM、TEM对复合材料进行了表征,测试了其电化学性能。结果表明,微米Si和纳米Ag_(2)O在球磨破碎过程中原位形成Si O和Ag颗粒,并附着在基体Si上,两种复合材料都展现出良好的倍率性能,在低电流密度(0.12 A/g)下Si/(SiO+Ag)和Si/(SiO+Ag)-C循环5次后分别表现出1422和1039 mA·h/g的可逆比容量,而在高电流密度(2.40 A/g)下仍能获得672和393 mA·h/g的可逆比容量;当电流密度再次恢复到0.12 A/g时,可逆比容量可恢复到1329和961m A·h/g,Si/(SiO+Ag)-C表现出更好的循环稳定性,经80次循环后可逆比容量仍稳定在943 m A·h/g,其突出的倍率性能归因于微米Si的颗粒细化以及球磨过程中原位反应形成纳米Ag颗粒导电特性,而循环稳定性的提高与原位形成Si O和包覆碳构成的双相缓冲结构有关。

Lithium batteries(LIBs) with low capacity graphite anode(~372 mAh g-1) cannot meet the ever-growing demand for new energy electric vehicles and renewable energy storage.It is essential to replace graphite anode with higher capacity anode materials for high-energy density LIBs.Silicon(Si) is well known to be a possible alternative for graphite anode due to its highest capacity(~4200 mAh g-1).Unfortunately,large volume change during lithiation and delithiation has prevented the Si anode from being commercialized.Metal silicides are a promising type of anode materials which can improve cycling stability via the accommodation of volume change by dispersing Si in the metal inactive/active matrix,while maintain greater capacity than graphite.Here,we present a classification of Si alloying with metals in periodic table of elements,review the available literature on metal silicide anodes to outline the progress in improving and understanding the electrochemical performance of various metal silicides,analyze the challenges that remain in using metal silicides,and offer perspectives regarding their future research and development as anode materials for commercial LIBs application.
