“…In addition, literature review showed that ZrC nanofibrous mesh has a good potential for various applications such as thermal storage packages and wear‐resistant coatings due to its high strength and thermal shock resistance . ZrC nanofibers have been synthesized via electrospinning technique using different zirconium and carbon sources such as zirconium acetyl acetonate (ZrAcAc), phenolic resins, zirconium (IV) acetyl acetonate, cellulose acetate, water‐soluble zirconium compound (ZC), poly(vinyl alcohol) (PVA) and zirconium oxychloride octahydrate, polyacrylonitrile (PAN), respectively . Up to now, the thinnest ZrC fibers were synthesized with the mean diameter of 710 nm after carbothermal reduction at 1600°C using ZrAcAc, cellulose acetate, and acetic acid to stabilize the sol .…”

The fabrication capability of zirconium carbide (ZrC) nanofibers by a novel polymeric solution was examined using electrospinning method. The electrospinnable solution was prepared from the reaction of zirconium n‐propoxide (Zr(OPr)4) with acetylacetone and acetic acid followed by the addition of polyvinylpyrrolidone (PVP) solution. By utilizing thermal and microstructural analyses such as differential scanning calorimetry–thermogravimetry (DSC–TG), field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD), and Brunauer–Emmett–Teller (BET), the effect of heat treatment type on the morphology and crystallinity of as‐spun PVP/Zr(OPr)4 hybrid fibers was examined. The results showed that direct carbonization treatment of as‐spun fibers under argon atmosphere led to spherical ZrC aggregates in lack of fibrillar morphology, whereas carbonization coupled with cyclization could be recognized as the unique template to govern the morphology and crystallinity of ZrC nanofibers. Carbonization of the cyclized fibers at 1550°C in flowing argon atmosphere produced the thick, fragmented rosary‐like fibers with a diameter of 357 nm, while through a 100°C decrease in carbonization temperature to 1450°C, the thin, smooth, long, and uniform ZrC nanofibers with 176 nm diameter and a medium surface area of 23 m2/g were obtained.

Bi 2 Sr 2 CaCu 2 O 8 (Bi-2212) superconducting nanowires are synthesized by the electrospinning method. Two different precursors were employed to grow the nanowires, a Pb-doped one and an Cu,Ca-enriched one. The granular polycrystalline character was confirmed by scanning electron microscopy and X-ray diffraction measurement.The magnetic and electric properties of the samples were investigated via SQUID magnetometry and four-probe resistance measurements. The superconducting transition temperature of both systems were found to be similar (Pb-doped 84 K, Cu,Caenriched 76 K), but the transition width and the onset of irreversibility were clearly different. The magnetization loops and the resistance data demonstrate that the Cu,Ca-enriched precursor yields samples with better superconducting properties. a)

Carbon nanofibers (CNFs) and its composites have gained vast attention due to its exceptional chemical and textural properties. So far, various multifunctional carbon nanofibers and its composites are developed with highly unique and tunable morphology. In this chapter, we reviewed unique fabrication methods that are recently reported and its characterization techniques such as SEM, FE-SEM, TEM, WAXD, XPS, AFM, and Raman. In addition, catalytic, energy, and environmental applications of carbon nanofiber composites (metals and/or metal oxide nanoparticles incorporated and/or decorated hybrid carbon nanofibers) are discussed. Preparation and characterization of electrospun carbon nanofiber composites and its applications in catalysis and energy storage are the main focus of this chapter.
