| 1 | Hierarchically electrospun nanofibers and their applications:A review显示文摘Electrospinning is a popular method for generating long and continuous nanofibers due to its simplicity and versatility.However,conventional electrospun products have weak strength and low availability,which restrict their functionality in complex applications.Hierarchical morphology introduces additional and distinctive structural layers onto electrospun fibers.This requires either an extra fabrication step or controlling electrospinning parameters to achieve the desired morphology.Hierarchical morphology can improve the properties of electrospun nanofibers while also mitigating the undesired characteristics.This review discusses the primary and secondary hierarchical structures of electrospun nanomaterials.Hierarchical structures were found to enhance the functionality of nanomaterials and improve pore connectivity and surface areas of electrospun nanofibers.A further advantage is the ability to impart multiple functionalities on nanostructures.With a better understanding of some of the dominant hierarchical structures,nanomaterials applications in drug delivery,tissue engineering,catalysis,and energy devices industries can be improved. | Muhammad Badmus Jing Liu NüWang Norbert Radacsi Yong Zhao | 2021 | Nano Materials Science2021，3，3： | 1 |

| 3 | Recent Advancements on Three‑Dimensional Electrospun Nanofiber Scaffolds for Tissue Engineering显示文摘Electrospinning is widely accepted as a technique for the fabrication of nanofibrous three-dimensional(3D)scaffolds which mimic extracellular matrix(ECM)microenvironment for tissue engineering(TE).Unlike normal densely-packed two-dimensional(2D)nanofibrous membranes,3D electrospun nanofiber scaffolds are dedicated to more precise spatial control,endowing the scaffolds with a sufficient porosity and 3D environment similar to the in vivo settings as well as optimizing the properties,including injectability,compressibility,and bioactivity.Moreover,the 3D morphology regulates cellular interaction and mediates growth,migration,and differentiation of cell for matrix remodeling.The variation among scaffold structures,functions and applications depends on the selection of electrospinning materials and methods as well as on the post-processing of electrospun scaffolds.This review summarizes the recent new forms for building electrospun 3D nanofiber scaffolds for TE applications.A variety of approaches aimed at the fabrication of 3D electrospun scaffolds,such as multilay-ering electrospinning,sacrificial agent electrospinning,wet electrospinning,ultrasound-enhanced electrospinning as well as post-processing techniques,including gas foaming,ultrasonication,short fiber assembly,3D printing,electrospraying,and so on are discussed,along with their advantages,limitations and applications.Meanwhile,the current challenges and prospects of 3D electrospun scaffolds are rationally discussed,providing an insight into developing the vibrant fields of biomedicine. | Yujie Chen Xutao Dong Muhammad Shafiq Gregory Myles Norbert Radacsi Xiumei Mo | 2022 | Advanced Fiber Materials2022，4，5： | 0 |
