Microstructures of as-prepared and calcined hollow TiO 2 fibers prepared by the electrospinning technique with a coaxial needle. Dynamic response at various CO concentrations for the sensor fabricated with the hollow TiO 2 fibers . ► Hollow TiO 2 fibers were synthesized using a coaxial ...
investigated the influence of the polymer solution concentration, the diameter of the electrospinning needle and the electrospinning time of uniaxial PLA/PCL fibers on the fiber diameter and elongation using a central composite design [22]. Rivero et al. applied the central composite DoE approach to...
The ZnO based nanorod has a quantum well or a coaxial quantum structure and is formed by alternately laminating two or more layers selected from the group consisting of a zinc oxide layer; an... GC Yi,WI Park - US 被引量: 646发表: 2004年 Coaxial electrospinning of (fluorescein ...
used to initiate a core–shell jet (Fig. 1a). At the exit of the core–shell needle attached to the syringe appears a core–shell droplet, which acquires a shape similar to the Taylor cone due to the pulling action of the electric Maxwell stresses acting on liquid. ...
Coaxial electrohydrodynamic jet (CE-Jet) printing is an encouraging method for fabrication of high-resolution micro and nanostructures in MEMS systems. This paper presents a novel simulation work based on phase field method which is considered as a preci

Core-shell nanofibers, also called as core-sheath nanofibers, are bicomponent nanofibers with core-shell structure produced by a special technology known as coaxial electrospinning. Theoretical and physical background of this method is mentioned here, and this chapter also deals with the development of...
The core–shell or coaxial nozzle is a concentric set of coaxial spinnerets composed of an outer and inner needle, as illustrated in Fig. 8.3A and B. Coaxial electrospinning can generate fibers from various solution pairs, such as, core-sheath, hollow, and functional fibers that may contain ...
