AB  - Nanomaterials form the main thrust for modern day technological and industrial applications, including but not limited to, super-capacitors, membranes, batteries, filters, sensors, tissue engineering, wound dressing, protecting vesture, reinforcement in composite materials, etc. Ceramic nanofibers are at the forefront of these materials due to their high surface area and tunable nano structures and porosity. However, obtaining nanofibers with a well-developed uniform crystallinity and a perfect morphology is a challenging task. Among various techniques utilized for preparation of nanofibers centrifugal jet spinning covets merits due to its high efficiency production rate, cost adequacy and operational safety. In the present manuscript we report preparation of TiO2 nanofibers by Sol–Gel Course with Centrifugal Jet Spinning using tetrabutyl titanate as main organic titanium precursor. Herein we demonstrate that a well-developed crystallinity and a perfect morphology of TiO2, from Nano to micro-scales, can be achieved after decomposition of polymer and removal of carbon. Effect of various factors such as PVP content, speed of rotation, humidity and heat treatment on the fiber growth was investigated. Effect of variation in soaking time and different temperatures on the TiO2 nanofiber grain growth was also investigated. Phase structure of TiO2 nanofibers was characterized by X-ray diffraction (XRD). Microstructure of the nanofibers was analyzed using Scanning Electron Microscopic (SEM) studies and Transmission Electron Microscope (TEM) studies. Kinetic exponents of grain growth were likewise acquired by with the help of an image processing software. Outcomes of our investigations show that crystallinity and morphology of grains of fibers are highly sensitive to temperature and soaking time. Image analysis demonstrates that sintering temperature greatly affects the crystallinity and grain size of the nanofibers over 700 °C.

AB  - The grain size and the ferroelectric morphology are the two most important factors in the research and development of advanced dielectric devices. It is important to synthesize nanostructures in order to achieve optimal grain size and inhibit grain growth while controlling the sintering parameters. It is also important to find new methods to study the grain growth during densification. BaTiO3 films were successfully obtained via the sol-gel spin coating method. In this paper, we report the deposition of nanostructured BaTiO3 thin film by spin coating of sol-gel precursors. The densification, grain growth and microstructure evolution have been studied. Moreover, a novel physical and mathematical fractal analysis have been applied successfully to the densification and nano grain growth of BaTiO3 thin film. The discrepancy between the fractal dimension and the grain growth with increasing temperatures and soaking time are presented and discussed.
