| 1 | Green Fabrication of Multifunctional Three‑Dimensional Superabsorbent Nonwovens with Thermo‑Bonding Fibers显示文摘Disposable hygiene products have evolved into the important parts for millions of people around the world,enhancing the convenience of daily lives.However,development of the disposable hygiene products is restricted by unsustainable production technology,complicated operation process,and poor liquid absorption performance of the absorbent core.Herein,integrated and three-dimensional(3D)multifunctional superabsorbent nonwovens with liquid-triggered fragrance release was prepared via green,fast and scalable multi efect hot-air anchoring method which physically crosslinking the joint thermobonding fbers and anchoring fragrance microcapsules/super absorbent polymer(SAP)onto adjacent thermo-bonding fbers simultaneously.The resulting composite nonwovens could three-dimensionally absorb water 33.14 times of its own weight without gel blockage between SAP,and correspondingly release increased intensity fragrance along with enhancing amount of water absorption.Absorption rate t1 and t2 is 83.62%and 50.62%higher than the commercial specimen respectively,and the air permeability is increased by 226.88%compared with the commercial specimen.The superabsorbent nonwovens with controllable fragrance release and odorant synergistic has the potential to be practically applied to functional textiles felds because of the excellent liquid absorption and controlled fragrance release performance,and is easy to be produced on a sustainable,pollution-free and large-scale industrial production. | Jiajia Ma Nan Zhang Ying Cheng Xingran Kou Yunwei Niu Xiangyu Jin Qinfei Ke Yi Zhao | 2022 | Advanced Fiber Materials2022，4，2： | 3 |

| 4 | Cobalt-based metal-organic framework as a dual cooperative controllable release system for accelerating diabetic wound healing显示文摘Nano Research volume 13,pages2268–2279(2020)Cite this article 131 Accesses 1 Altmetric Metrics details Abstract Insufficient angiogenesis in the chronic wound of the diabetic is one of the most important causes that making the wound unable to heal itself.In this work,a cobalt-based metal–organic framework(ZIF-67)was introduced as a carrier for loading a pro-angiogenic small molecular drug(dimethyloxalylglycine,DMOG).To achieve a long-term angiogenic therapy on the diabetic wound beds,a dual cooperative controllable release system has been designed by incorporating the drug-loaded ZIF-67 nanoparticles into the micro-patterned PLLA/Gelatin nanofibrous scaffolds.The results showed that DMOG was incorporated into ZIF-67 with a high loading ratio(359.12 mg/g),and the drug-loaded ZIF-67 nanoparticles were well embedded in the circular patterned scaffold.Notably,the DMOG as well as Co ions could continuously release from the scaffold for more than 15 days.The in vitro studies showed that the released Co ions and DMOG from the micropatterned nanofibrous scaffolds could synergistically promote the proliferation,migration and tube formation of the human umbilical vein endothelial cells(HUVECs)by inducing a hypoxia response and upregulating the expression of angiogenesis-related genes such as HIF-1α,VEGF and e-NOS.Furthermore,the in vivo results demonstrated that the composite scaffolds could significantly enhance angiogenesis,collagen deposition and eliminate inflammation in the diabetes wounds.These results indicate that the cobalt-based metal–organic framework as a dual cooperative controllable release system provides a new strategy for enhancing angiogenesis and promoting diabetic wound healing. | Jiankai Li Fang Lv Jinxiu Li Yuxin Li Jingduo Gao Jian Luo Feng Xue Qinfei Ke He Xu | 2020 | Nano Research2020，13，8： | 1 |

| 7 | Downy 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 | 2022 | Nano Research2022，15，6： | 1 |

| 10 | In Situ Synthesis of Cuprous Oxide/Cellulose Nanofibers Gel and Antibacterial Properties显示文摘Cellulose nanofibers were synthesized by acetobacter xylinum(xylinum 1.1812).The cellulose nanofibers with 30-90 nm width constructed three-dimension network gel,which could be used as a wound dressing since it can provide moist environment to a wound.However,cellulose nanofibers have no antimicrobial activity to prevent wound infection.To achieve antimicrobial activity,the cellulose nanofibers can load cuprous oxide(Cu2O)particles on the surface.The cuprous oxide is a kind of safe antibacterial material.The copper ions can be reduced into cuprous oxides by reducing agents such as glucose,N2H4 and sodium hypophosphite.The cellulose nanofibers network gel was soaked in CuSO4 solution and filled with copper ions.The cuprous oxide nanoparticles were in situ synthesized by glucose and embedded in cellulose nanofibers network.The morphologies and structure of the composite gel were analyzed by FESEM,FTIR,WAXRD and inductively coupled plasma(ICP).The sizes of Cu2O embedded in cellulose nanofibers network are 200-500 nm wide.The peak at 605 cm−1 attributed to Cu(I)-O vibration of Cu2O shits to 611 cm−1 in the Cu2O/cellulose composite.The Cu2O/cellulose nanofibers composite reveals the obvious characteristic XRD pattern of Cu2O and the results of ICP show that the content of Cu2O in the composite is 13.1%.The antibacterial tests prove that the Cu2O/cellulose nanofibers composite has the high antibacterial activities which is higher against S.aureus than against E.coli. | Ying Hu Qinfei Ke Zhe Li Wanli Han Zhiyong Yan | 2018 | Computers, Materials & Continua2018，，9： | 1 |
| 11 | Grooved 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 | 2022 | Advanced Fiber Materials2022，4，2： | 1 |
| 12 | Enhanced 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 | 2023 | Nano Research2023，16，1： | 0 |
| 13 | Electrospun Textile Strategies in Tendon to Bone Junction Reconstruction显示文摘The repair of tendon to bone junction(TBJ)remains a tremendous challenge in tissue engineering due to the complicated structure,components,mechanical properties,and cell types.In order to reconstruct the tissue and restore its functionality,biomedical scaffolds with hierarchical and gradient structures have been fabricated by various strategies.In recent decades,electrospinning has become one of the most popular methods in fabricating TBJ scaffolds due to easy fabrication,high porosity,and ECM-like nano-scale structure.However,mechanical properties are the pain point of electrospun biomedical scaffolds.Traditional textile technology can be exploited to compensate for this weakness,which will be deeply discussed here.This review will start with a brief introduction to the structure and function of the native TBJ tissue and a short overview of electrospinning technology.Then,different electrospun biomedical scaffolds for TBJ repair will be summarized and compared.Furthermore,some advanced technologies and modification methods in fabricating functionalized electrospun TBJ scaffolds are discussed.In the end,current challenges and solutions are being proposed,which would provide instruction for the research of electrospun textile TBJ scaffolds. | Xiaoyun Xu Yifan Si Yi Zhao Qinfei Ke Jinlian Hu | 2023 | Advanced Fiber Materials2023，5，3： | 0 |
| 14 | Adaptable 'bubble particles' prepared by green aqueous phase reshaping for completely removing odor显示文摘Facile and ecofriendly loading of micro/nano function-specific substances to create functional materials is a trend being pursued by researchers.However,current micro/nano particles loading approaches are often hindered by issues such as uneven distribution,unsatisfactory stability and complicate procedure.In this work,we present an aqueous phase reshaping method that only utilizes the moisture to fabricate the'bubble particles',which could perfectly cater to the topography of the substrate.The green preparation of bubble particles adopts an absolutely zero-pollution method,realizing the firm loading of particles on the substrate.Integrating the preparation and loading of particles overcomes the traditional complicate process,while the aqueous phase reshaping ensures uniform and firm loading of the'bubble particles'onto the substrate.Our mechanism demonstrates a significant enhancement in the interface relation after aqueous phase reshaping,with a 121-fold increase in contact surface area achieved by reducing the height by 1μm.Furthermore,we explore for the first time the influence of the nature of the receiving substrate on the interface morphology of particles during electrostatic spraying,which has important guiding significance for the interface relationship of electrostatic spraying and even electrostatic spinning materials.We also screen out the natural antibacterial essential oil linalool as the effective specialized antibacterial agent,which can specifically inhibit the odor-producing Proteus in urine,with an antibacterial rate of up to 100%.Taken together,this simple,ecofriendly method for fabricating functional materials with optimal interface stability appears highly promising for use in various products formed by electrostatic spraying/spinning. | Jiajia Ma Yichang Xia Tienan Zhao Wenfeng Hu Weifeng Zhang Qinfei Ke Yi Zhao | 2024 | Nano Research2024，17，3： | 0 |
| 15 | Metal-organic framework composites for energy conversion and storage显示文摘Metal-organic frameworks(MOFs)with orderly porous structure,large surface area,high electrochemical response and chemical tunability have been widely studied for energy conversion and storage.However,most reported MOFs still suffer from poor stability,insufficient conductivity,and low utilization of active sites.One strategy to circumvent these issues is to optimize MOFs via designing composites.Here,the design principle from the viewpoint of the intrinsic relationships among various components will be illuminated to acquire the synergistic effects,including two working modes:(1)MOFs with assistant components,(2)MOFs with other function components.This review introduces recent research progress of MOF-based composites with their typical applications in energy conversion(catalysis)and storage(supercapacitor and ion battery).Finally,the challenges and future prospects of MOF-based composites will be discussed in terms of maximizing composite properties. | Hang Wang Na Zhang Shumin Li Qinfei Ke Zhengquan Li Min Zhou | 2020 | Journal of Semiconductors2020，41，9： | 0 |
