1Grinding temperature and energy ratio coefficient in MQL grinding of high-temperature nickel-base alloy by using different vegetable oils as base oil显示文摘Vegetable oil can be used as a base oil in minimal quantity of lubrication(MQL). This study compared the performances of MQL grinding by using castor oil, soybean oil, rapeseed oil, corn oil, sunflower oil, peanut oil, and palm oil as base oils. A K-P36 numerical-control precision surface grinder was used to perform plain grinding on a workpiece material with a high-temperature nickel base alloy. A YDM–III 99 three-dimensional dynamometer was used to measure grinding force,and a clip-type thermocouple was used to determine grinding temperature. The grinding force, grinding temperature, and energy ratio coefficient of MQL grinding were compared among the seven vegetable oil types. Results revealed that(1) castor oil-based MQL grinding yields the lowest grinding force but exhibits the highest grinding temperature and energy ratio coefficient;(2) palm oil-based MQL grinding generates the second lowest grinding force but shows the lowest grinding temperature and energy ratio coefficient;(3) MQL grinding based on the five other vegetable oils produces similar grinding forces, grinding temperatures, and energy ratio coefficients, with values ranging between those of castor oil and palm oil;(4) viscosity significantly influences grinding force and grinding temperature to a greater extent than fatty acid varieties and contents in vegetable oils;(5) although more viscous vegetable oil exhibits greater lubrication and significantly lower grinding force than less viscous vegetable oil, high viscosity reduces the heat exchange capability of vegetable oil and thus yields a high grinding temperature;(6) saturated fatty acid is a more efficient lubricant than unsaturated fatty acid; and(7) a short carbon chain transfers heat more effectively than a long carbon chain. Palm oil is the optimum base oil of MQL grinding, and this base oil yields 26.98 N tangential grinding force,87.10 N normal grinding force, 119.6 °C grinding temperature, and 42.7% energy ratio coefficient.Li Benkai Li Changhe Zhang Yanbin Wang Yaogang Jia Dongzhou Yang Min 2016Chinese Journal of Aeronautics2016,29,4:20
2Advanced Functional Fiber and Smart Textile显示文摘The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry.However,the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society,as well as people’s consumption needs in pursuit of smart,avant-grade,fashion and distinctiveness.The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years.The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment.In this review,the significant progress on flexible fiber-shaped multifunctional devices,including fiber-based energy harvesting devices,energy storage devices,chromatic devices,and actuators are discussed.Particularly,the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells,lithium-ion batteries,actuators and electrochromic fibers are introduced in detail.Finally,we provide our perspectives on the challenges and future development of functional fiber-shaped devices.Qiuwei Shi Jianqi Sun Chengyi Hou Yaogang Li Qinghong Zhang Hongzhi Wang 2019Advanced Fiber Materials2019,1,1:7
3Light-driven artificial muscles based on electrospun microfiber yarns显示文摘Artificial muscles are widely potential in diverse fields including medical treatment, humanoid robotics and industrial automation. Soft materials due to bio-friendly interaction are suitable for those applications. Planar and fiber shape based artificial muscles that use the polymer as substrate materials can be triggered by various stimuli like electric, moisture and heat. Here,artificial muscles based on electrospun microfiber yarns are demonstrated, which can be remotely controlled. The carbon nanotubes embedded in polyurethane microfibers enable the yarns to efficiently absorb near-infrared light and radiate heat,which induces the fast temperature change that leads to the contraction/expansion motions along the axial direction. Microfiber mats are collected by a rotating cylinder that results in highly oriented alignment. The yarns from microfiber mats are highly twisted into the coiled structure, which generates maximum contractive actuation of 6.7% at 70°C. 1000 cycles were demonstrated without an obvious decline of actuating performances. The light-driven artificial muscles can be potentially applied in wireless control, bio-medical devices and so on.MENG JunXing HOU ChengYi ZHANG QingHong LI YaoGang WANG HongZhi 2019Science China(Technological Sciences)2019,62,6:3

7Fabrication and characterization of amorphous ITO/p-Si heterojunction solar cell显示文摘Amorphous indium-tin-oxide(a-ITO) film was deposited by radio-frequency(RF) magnetron sputtering at 180°C substrate temperature on the texturized p-Si wafer to fabricate a-ITO/p-Si heterojunction solar cell.The microstructural,optical and electrical properties of the a-ITO film were characterized by XRD,SEM,XPS,UV-VIS spectrophotometer,four-point probe and Hall effect measurement,respectively.The electrical properties of heterojunction were investigated by I-V measurement,which reveals that the heterojunction shows strong rectifying behavior under a dark condition.The ideality factor and the saturation current density of this diode are 2.26 and 1.58×10-4 A cm-2,respectively.And the value of IF/IR(IF and IR stand for forward and reverse currents,respectively) at 1 V is found to be as high as 21.5.For the a-ITO/p-Si heterojunction solar cell,the a-ITO thin film acts not only as an emitter layer,but also as an anti-reflected coating film.The conversion efficiency of the fabricated a-ITO/p-Si heterojunction cell is approximately 1.1%,under 100 mW cm-2 illumination(AM1.5 condition).And the open-circuit voltage(Voc),short-circuit current density(J SC),filll factor(FF) are 280 mV,9.83 mA cm 2 and 39.9%,respectively.Because the ITO film deposited at low temperature is amorphous,it can effectively reduce the interface states between ITO and p-Si.The barrier height and internal electric field,which is near the surface of p-Si,can effectively be enhanced.Thus we can see the great photovoltaic effect.HE Bo WANG HongZhi LI YaoGang MA ZhongQuan XU Jing ZHANG QingHong WANG ChunRui XING HuaiZhong ZHAO Lei WANG DunDong 2013Science China(Technological Sciences)2013,56,8:2

11All-inorganic quantum-dot light-emitting-diodes with vertical nickel oxide nanosheets as hole transport layer显示文摘All-inorganic quantum dot light emitting diodes(QLEDs) have gained great attention as a result of their high stability under oxygen-rich, humid and high current working conditions. In this work, we have fabricated an allinorganic QLED device(FTO/NiO/QDs/AZO/Ag) with sandwich-structure, wherein the inorganic metal oxides thin films of NiO and AZO were employed as hole and electron transport layers, respectively. The porous NiO layer with vertical lamellar nanosheets interconnected microstructure have been directly synthesized on the substrate of conductive FTO glass and increased the wettability of CdSe@ZnS QDs, which result in an enhancement of current transport performance of the QLED.Jiahui Li Yuanlong Shao Xuecheng Chen Hongzhi Wang Yaogang Li Qinghong Zhang 2016Progress in Natural Science:Materials International2016,26,5:1

17Analysis of isolation of cerebral cortical neurons in rats by different methods显示文摘The aim of this study was to find a way to efficiently separate neuronal cells from the cerebral cortex of adult rats,providing a reference method for rapid acquisition of neuronal cells from the adult rat brain.Fifteen SD rats were randomly divided into three groups,with five SD rats in each group.Then,neuron cells were isolated from the adult rat cerebral cortex by the grinding method,the trypsin method,and the collagenase II method,respectively.The expression of anti-NeuN in the neurons of each group was analyzed by flow cytometry.The acquisition rates and morphology of neurons of each group were observed by immunofluorescence staining.The grinding or collagenase II method is more suitable for rapid acquisition of neuronal cells from an adult rat’s cerebral cortex.The number of neuron cells obtained by the trypsin method were very few,so it is not convenient for later experiments.JIANHUA LI YAOGANG ZHANG TAO ZHANG MEIYUAN TIAN JING HOU DENGLIANG HUANG YAN CHENG ZHU MAN XIAOMING SU ZHIQIN LI SIXIAN TONG XUAN ZHANG JUN DENG YUN DONG YANYAN MA 2020BIOCELL2020,44,2:1
