| 2 | Characteristics and Formation Mechanism for Stainless Steel Fiber with Periodic Micro-fins显示文摘Metal fibers have been widely used in many industrial applications due to their unique advantages. In certain applications, such as catalyst supports or orthopedic implants, a rough surface or tiny outshoots on the surface of metal fibers to increase surface area are needed. However, it has not been concerned about the surface morphologies of metal fiber in the current research of metal fiber manufacturing. In this paper, a special multi-tooth tool composed of a row of triangular tiny teeth is designed. The entire cutting layer of multi-tooth tool bifurcates into several thin cutting layers due to tiny teeth involved in cutting. As a result, several stainless steel fibers with periodic micro-fins are produced simultaneously. Morphology of periodic micro-fins is found to be diverse and can be classified into three categories: unilateral plane, unilateral tapering and bilateral. There are two forming mechanisms for the micro-fins. One is that periodic burrs remained on the free side of cutting layer of a tiny tooth create micro-fins of stainless steel fiber produced by the next neighboring tiny tooth; the other is that the connections between two fibers stuck together come to be micro-fins if the two fibers are finally detached. Influence of cutting conditions on formation of micro-fins is investigated. Experimental results show that cutting depth has no significant effect on micro-fin formation, high cutting speed is conducive to micro-fin formation, and feed should be between 0.12 mm/r and 0.2 mm/r to reliably obtain stainless steel fiber with micro-fins. This research presents a new pattern of stainless steel fiber characterized by periodic micro-fins formed on the edge of fiber and its manufacturing method. | TANG Tao WAN Zhenping LU Longsheng TANG Yong | 2016 | Chinese Journal of Mechanical Engineering2016，29，3： | 1 |

| 5 | Prevalence and Patterns of Multimorbidity Among Adults Aged 18 Years and Older—China,2018显示文摘Summary What is already known about this topic?Multimorbidity is becoming more common and poses a major challenge to healthcare systems.However,the prevalence and patterns of multimorbidity among Chinese adults aged≥18 years are largely unknown.What is added by this report?This study found that 46.5% of Chinese adults had multimorbidity in 2018.And the prevalence of multimorbidity prevalence is increased with age.Prevalence of multimorbidity was higher among men,Han Chinese,adults with lower educational level,and those with lower household income.The most common multimorbidity pattern is a combination of three chronic conditions,hypertension,dyslipidemia,and obesity. | Ye Geng Wan Jie Yuan He Xiaolong Zhou Sijia Zhang Wenlan Dong Zhenping Zhao Xiaoguang Cheng Jing Wu | 2023 | China CDC weekly2023，5，2： | 1 |
| 6 | Direct mask-free fabrication of patterned hierarchical graphene electrode for on-chip micro-supercapacitors显示文摘Graphene-based electrodes with rational structural design have shown extraordinary prospect for en-hanced electrical double-layer capacitance of micro-supercapacitors(MSCs).Herein,a facile fabrication method for flexible planar MSCs based on hierarchical graphene was demonstrated by using a laser-treated membrane for electrode patterning,complemented with hierarchical electrode configuration tak-ing full advantages of size-determined functional graphene.The in-plane interdigital shape of MSCs was defined through vacuum filtration with the assistance of the functionalized polypropylene(PP)mem-brane.The hierarchical graphene films were built by macroscopic assembly based on size effect of differ-ent lateral sized graphene sheets(rGO-LSL).The sample of MSCs based on rGO-L SL(MSCs-LSL)exhibited excellent volumetric capacitance of 6.7 F cm^(−3) and high energy density of 0.37 mWh cm−3.The MSCs-LSL presented superb flexibility and cycling stability with no capacitance deteroriated after 2000 cycles.This newly developed fabrication strategy is of good scalability and designability to manufacture flexible elec-trode for MSCs with customized shapes,while the construction of hierarchical graphene can enlighten the structural design of analogous two-dimensional materials for potential advanced electronics. | Yaopeng Wu Jinghong Chen Wei Yuan Xiaoqing Zhang Shigen Bai Yu Chen Bote Zhao Xuyang Wu Chun Wang Honglin Huang Yong Tang Zhenping Wan Shiwei Zhang Yingxi Xie | 2023 | Journal of Materials Science & Technology2023，，12： | 0 |
| 7 | An easy-to-implement method for fabricating superhydrophobic surfaces inspired by taro leaf显示文摘An easy-to-implement method by which to fabricate superhydrophobic surfaces inspired taro leaf was successfully applied on316 L stainless steel via combining nanosecond laser(NL)processing and spin-coating techniques.The laser-textured surface composed of microscale frameworks and central bumps was fabricated by NL processing based on properly designed biomimetic patterns,and a layer of nanoscale carbon black/polydimethylsiloxane(CB/PDMS)particles was covered on it by spin-coating.The effect of pattern parameters(i.e.,the inscribed circle radius of framework and the radius of central bump)on wettability of biomimetic surface was investigated.All as-prepared biomimetic surfaces with micro-nano hierarchical structures showed excellent superhydrophobicity with the water contact angle of~155°and contact angle hysteresis of~2°.By comparing the untreated surface,the wetting behavior and evaporation mode of the biomimetic surface occurred an obvious transformation.Meanwhile,experiments indicated that the biomimetic surface not only had liquid-repelling and self-cleaning functions,but also maintained remarkable mechanical robustness and superhydrophobic durability.The method is efficient for fabricating biomimetic superhydrophobic surfaces applied to liquid-repelling,evaporation-transforming and self-cleaning fields. | LI KaiKai LEI Jiang XIE YingXi LU LongSheng ZHANG ShaoHui ZHOU PeiYang LIANG RongXuan WAN ZhenPing TANG Yong | 2021 | Science China(Technological Sciences)2021，64，12： | 0 |
| 8 | Fabrication of electrospun bilayer separators for lithium-sulfur batteries:A surface and structure dual modification strategy显示文摘The severe shuttle effect problem of soluble polysulfides greatly hinders the development of long-life lithium-sulfur(Li-S)batteries,which can be improved by separator modification.This study develops a bilayer separator based on an effective surface and structure dual modification strategy.This bilayer separator(named as TCNFs/SPNFs)is constructed by the integration of a carbon-based nanofiber layer(surface modification layer)with a polymer-based nanofiber layer(structure modification layer)through a facile electrospinning process.The excellent electrolyte wettability of the nanofibers accelerates lithium-ion migration,while the good electronic conductivity of the carbon layer facilitates fast electron conduction.The TiO_(2)and SiO_(2)nanoparticles embedded in the separator provide abundant active sites for immobilizing the polysulfides.Owing to these synergistic effects,this multi-functional separator helps inhibit the shuttling problem and thus enhances the active sulfur utilization.The as-prepared battery with the TCNFs/SPNFs separator delivers significantly enhanced the electrochemical performances,producing a low capacity decay rate of 0.061%per cycle at 1 C over 1000 cycles and an admirable rate capacity of 886.7 mAh g^(-1)at 2 C.Even with a high sulfur loading of 4.8 mg cm^(-2),a remarkable areal capacity of 6.0 mAh cm^(-2)is attained.This work is believed to provide a promising strategy to develop novel separators for high-performance Li-S batteries. | XU Ming ZHANG XiaoQing YUAN Wei HUANG HongLin WU YaoPeng WAN ZhenPing LU LongSheng TANG Yong | 2022 | Science China(Technological Sciences)2022，65，12： | 0 |
