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...
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
reviews. Therefore, the current mini-review briefly outlines the basic features of the process and proceeds toward its deeper physical understanding, modifications, and recent applications. FIRST STEPS OF CO-ELECTROSPINNING Coaxial electrospinning (co-electrospinning) was introduced first in ...
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 ...

The as-obtained polymer solution was electrospun with a 21-gauge needle in the following conditions: Material characterization The synthesis process of hollow core-shell structured CNT/PAN@Co9S8@C coaxial nanocables is schematically shown in Fig. 1. Firstly, electrospinning CNT/PAN nanofibers were...
produced monodisperse compound droplets using the coaxial electrohydrodynamic atomization process for the encapsulation of micro/nano materials [11]. Sun et al. generated special compositions known as core-shell polymer nanofibers by the co-electrospinning method using PEO polymer material as the internal ...
the distance from the needle to the roller was 12 cm; and the speed of the roller was 400 r min−1. After coaxial electrospinning, the sample was subjected to heat treatment to obtain the CoS1.097@C core–shell fibers. The heat treatment included two stages. The first was pre-oxidation...
2.3. Theoretical Model Analysis and Numerical Simulation of Coaxial Jet Process The bioink enters the outer runner through the outer nozzle inlet and the cross-linking agent enters the inner runner through the inner needle inlet. Both flow through the lumen and out at the nozzle outlet, where th...
