“…6 and 8), the morphology of the fibers changed dramatically from smooth and uniform fibers to a linked-particle tubular form(particulate morphology). The porous fibers became disconnected when they were annealed at 1000 C. This is particularly important, because the fiber morphology is attributed to the calcination temperature [10,11,14,15]. …”

“…The Ru-TiO 2 nanofibers were characterized by examining their viscosity, surface tension, and morphology [10,11]. The kinematic viscosity, surface tension, and density of the precursor solution were determined using a Cannon-Fenske viscometer, a dynamic tensiometer(Nima, DST9005, USA) and a pycnometer, respectively.…”

Ruthenium(Ru)-doped TiO 2 nanofibers were prepared using electrospun Ru-TiO 2 /poly(vinyl acetate) (PVAc) fibers and subsequent annealing for 1 h at temperatures in the range of 500 C to 1000 C in air. The properties of the Ru-TiO 2 fibers were characterized as a function of the Ru content and calcination temperature using X-ray diffraction, thermal gravimetry with differential scanning calorimetry, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, and viscometer, pycnometer and dynamic tensiometer measurements. Although the diameter of the fiber decreased slightly with increasing calcination temperature, no dramatic changes were observed with respect to the ruthenium content. The XRD and FT-IR results revealed that anatase phase and ruthenium metal began to be formed after calcination at temperatures above 500 C. Anatase and rutile phases and ruthenium metal coexisted in the fibers calcined above 600 C. No anatase phase was detected in the fibers containing ruthenium when they were calcined at 1000 C. The morphology of the fibers changed from smooth and uniform to porous with increasing temperature. The experimental results suggest that the calcination temperature and Ru content were influential in determining the morphology and structure of the fibers.

“…1, two main exothermic peaks appear in the DSC curves of SrTiO 3 dry gel with and without PVP. The first main exothermic peaks, due to decomposition of the main organic groups [9], are at 390 and 425°C, respectively. The second main exothermic peaks at 580 and 560°C, corresponding to SrTiO 3 dry gel without PVP and PVP-modified SrTiO 3 dry gel respectively, may be associated with the formation of SrTiO 3 perovskite [9].…”

In the case of SrTiO 3 dry gel without PVP, the DSC curves show an endothermic peak at 934°C corresponding to the phase transformation of SrCO 3 , this is in good agreement with previous report (also heating rate with 10°C/min) [10].…”

Dielectric breakdown behavior of sol-gel derived SrTiO 3 films has been studied systematically. The dielectric strength and leakage characteristics of SrTiO 3 films were observed to have a strong dependence on the top electrode materials. Compared with films with Ti or Al electrode, SrTiO 3 films with Au electrode exhibited relatively low dielectric breakdown strength. Simultaneously, a broad area of damage occurred in the Au electrode after breakdown, which is closely related to the self-healing breakdown mechanism. The corresponding leakage current kept the same order of magnitude when the electric field was higher than 100 MV/m. The higher dielectric strength of the films with Ti or Al electrode is attributed to anodic oxidation of metal electrode.

The field of nanotechnology has been gaining great success due to its potential in developing new generations of nanoscale materials with unprecedented properties and enhanced biological responses. This is particularly exciting using nanofibers, as their mechanical and topographic characteristics can approach those found in naturally occurring biological materials. Electrospinning is a key technique to manufacture ultrafine fibers and fiber meshes with multifunctional features, such as piezoelectricity, to be available on a smaller length scale, thus comparable to subcellular scale, which makes their use increasingly appealing for biomedical applications. These include biocompatible fiber-based devices as smart scaffolds, biosensors, energy harvesters and nanogenerators for the human body. This paper provides a comprehensive review of current studies focused on the fabrication of ultrafine polymeric and ceramic piezoelectric fibers specifically designed for, or with the potential to be translated toward, biomedical applications. It provides an applicative and technical overview of the biocompatible piezoelectric fibers, with actual and potential applications, an understanding of the electrospinning process, and the properties of nanostructured fibrous materials, including the available modeling approaches. Ultimately, this This article is protected by copyright. All rights reserved. 3 review aims at enabling a future vision on the impact of these nanomaterials as stimuli-responsive devices in the human body.
