“…Then, the solution was loaded in a 10-ml syringe and spun using the solution blow spinning (SBS) technique as described in Refs. (Rotta et al 2016;Rotta et al 2019) with an injection rate of 3 ml/h. The needle used was of type 25G (0.5-mm diameter) and the air pressure was adjusted to 1 kPa with the collector set to 40 cm, and the rotation speed at 40 rpm.…”

The microstructure and magnetic characterizations of non-woven, fabric-like YBa2Cu3Oy (YBCO) nanofiber mats are reported. The samples were produced by solution blow spinning (SBS), starting from a sol-gel solution of the precursor materials in polyvinylpyrrolidone. In the present work, the nanowire network samples were morphologically characterized by scanning electron microscopy, and the superconducting properties were measured by magnetometry. An interesting feature is the appearance of a paramagnetic Meissner effect (PME) when field-cooling, firstly verified in that sort of sample. The PME appears only in very small applied magnetic fields, which is similar to previous observations of the PME on an artificially granular YBCO thin film, but distinctly different from bulk samples investigated in the literature. Thus, we explain the PME by flux trapping within the voids of the nanoporous structure of the nanofiber mats.

“…Thus, electrospinning [ 85 , 86 , 87 ] and solution-blow spinning [ 88 , 89 ] have completely overrun the template approach, enabling the growth of longer and homogeneous HTSc nanowire fabrics, from which individual pieces can easily be cut off using FIB [ 72 , 90 ]. Furthermore, the nanowire fabrics themselves have interesting electric and magnetic properties [ 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 ], which may lead to specific applications which are not possible with other types of HTSc materials.…”

The fabrication and characterization of superconducting nanowires fabricated by the anodic aluminium oxide (AAO) template technique has been reviewed. This templating method was applied to conventional metallic superconductors, as well as to several high-temperature superconductors (HTSc). For filling the templates with superconducting material, several different techniques have been applied in the literature, including electrodeposition, sol-gel techniques, sputtering, and melting. Here, we discuss the various superconducting materials employed and the results obtained. The arising problems in the fabrication process and the difficulties concerning the separation of the nanowires from the templates are pointed out in detail. Furthermore, we compare HTSc nanowires prepared by AAO templating and electrospinning with each other, and give an outlook to further research directions.

“…Due to miniaturization and future applications in various fields, such as electronics and medicine, the market for nanostructured materials can grow exponentially. Fast output rates are therefore necessary in order to make nanomaterials commercially available [64]. SBS is considered to be maturing among the new technologies used for the development of nanofibres, primarily because of its capacity to generate the most nanofibres in the shortest possible time [30].…”

Submicron/nanofibres possess great potential for application in different areas because of their amazingly high surface area-to-weight ratio. The demand for fabrication of such fibres on a huge scale is increasing with the fast improvement of nanotechnology. Traditionally, nanofibre fabrication methods have intrinsic faults, limiting their application in industry. Solution blow spinning (SBS) is a viable option for producing adaptable and conformable submicron/nanofibre mats on a variety of surfaces. The technique can be employed to produce submicron/ nanofibres with only a simple commercial airbrush, a concentrated polymer solution, and a compressed gas source. It depends on the high velocity of decompressed air that allows the rapid stretching and evaporation of the solvent from a polymeric solution jet at the outlet of the concentric nozzles system. Along with recent advancements, the importance and drawbacks of the solution blow spinning system in comparison to other methods, such as electrospinning and melt blowing, are briefly discussed. Furthermore, the mechanisms of co-axial SBS spinning and micro SBS spinning system for submicron/nanofibre fabrication are also described. Drawbacks and research challenges of SBS are also addressed in this paper.
