2Downy feather-like para-aramid fibers and nonwovens with enhanced absorbency,air filtration and thermal insulation performances显示文摘Fiber morphology with off-standing branches,as found in nature,e.g.,in goose downy feather,provides exquisite functions that can be barely achieved by man-made fiber systems.In this work,we develop a simple and scalable method for generating downy feather-like para-aramid fibers and assemblies.Through treating commercial para-aramid microfibers with mild alkaline solution(low concentration of NaOH),a synergistic effect of chemical hydrolysis and physical shearing is successfully triggered to generate abundant nanofiber branches on the surface of para-aramid fibers.When compared with conventional monotonous structures,nonwovens composed of downy feather-like fibers exhibit a typical multiscale fiber morphology,larger specific surface area and smaller pore size,thus showing enhanced particles adsorption capacity(over twice of the pristine nonwoven),excellent oil absorption capacity(increased by~50%),improved air filtration performances(doubled the filtration efficiency)and effective thermal insulation(thermal conductivity=26.1 mW·m^(−1)·K^(−1)).More attractively,the intrinsic flame-retardant nature of para-aramid is well inherited by the downy feather-like fibers,and the fabrication process requires neither sophisticated equipment,nor tedious procedures,making us believe the strong competitiveness of these fibers and assemblies.Kangli Xu Jixia Deng Guangliang Tian Lei Zhan Jiajia Ma Lijun Wang Qinfei Ke Chen Huang 2022Nano Research2022,15,6:1
3Grooved Fibers:Preparation Principles Through Electrospinning and Potential Applications显示文摘The surface morphology of micro-and nano-scale fber determines its application to a great extent.At present,a variety of secondary morphology of microfbers and nanofbers,such as porous,wrinkle,groove and so on,have been prepared.Among them,grooved micro-and nano-fbers are attracting more and more attention because of their unique morphology and properties.In this paper,we review the literature on grooved fbers due to void-based elongation,wrinkle-based elongation,collapsed jet-based elongation and selective dissolution.By contrast,the method of phase separation is simpler and more commonly used than selective dissolution.What is more interesting is that the number and depth of grooves on the fber surface can be well controlled by adjusting the experimental parameters,which greatly increases the research value and application felds of grooves micro-nano fbers.Grooved fbers can be made from a range of materials:polycaprolactone(PCL),polylactic acid(PLA),polystyrene(PS),cellulose acetate butyrate(CAB)and other polymers.The applications of grooved micro-nano fbers are discussed in detail,including peripheral nerve regeneration,water manipulation and energy conversion.Lei Zhan Jixia Deng Qinfei Ke Xiao Li Yuanming Ouyang Chen Huang Xuqing Liu Yun Qian 2022Advanced Fiber Materials2022,4,2:1
4Enhanced cellular infiltration of tissue-engineered scaffolds fabricated by PLLA nanogrooved microfibers显示文摘Nanofibers prepared by electrospinning technique are extensively applied as building blocks for tissue-engineered scaffolds because of their high resemblance to natural extracellular matrix(ECM)and the capacity to provide more cell contacts than microfibers.However,conventional electrospun scaffolds only allow superficial growth of cells in that the size of inter-fiber pores is much smaller than the size of cells.By taking advantage of the positive correlation between fiber diameter and pore size in fibrous materials,we report here a simple method for fabricating poly-L-lactic acid(PLLA)microfiber scaffold with longitudinally aligned nanogrooves on fiber surface.Three-dimensional(3D)and structurally stable PLLA scaffolds with an average pore size of 16μm were successfully acquired when the fiber diameter was 4.22μm.The topographical cues from nanogrooves ensured fast cell adhesion of scaffolds,whilst the large inter-fiber pores enabled sufficient cell infiltration.Moreover,the nanogrooved microfiber scaffold showed improved curative effects of wound healing in a rat skin injury model,making us believe its practical significance in biomedical areas that requires fast cell adhesion and high cell infiltration.Lei Zhan Lingtian Wang Jixia Deng Yi Zheng Qinfei Ke Xinrui Yang Xing Zhang Weitao Jia Chen Huang 2023Nano Research2023,16,1:0
5A Fast Radio Burst Backend for the Tianlai Dish Pathfinder Array显示文摘The Tianlai Dish Pathfinder Array is a radio interferometer array consisting of 16 six-meter dish antennas.The original digital backend integration time is at the seconds level,designed for H I intensity mapping experiment.A new digital backend with millisecond response is added to enable it to search for fast radio burst during its observations.The design and calibration of this backend,and the real time search pipeline for it are described in this paper.It is capable of forming 16 digital beams for each linear polarization,covering an area of 19.6 square degrees.The search pipeline is capable of searching for,recording and classifying FRBs automatically in real time.In commissioning,we succeeded in capturing the signal pulses from the pulsars PSR B0329+54 and B2021+51.Zijie Yu Furen Deng Shijie Sun Chenhui Niu Jixia Li Fengquan Wu Wei-Yang Wang Yougang Wang Hui Feng Lin Shu Jie Hao Reza Ansari Albert Stebbins Xuelei Chen 2022Research in Astronomy and Astrophysics2022,22,12:0
