“…Similarly, the BCLF (Ba 0.2 Cu 0.8-x La x Fe 2 O 4 (x = 0.2-0.6)), and BCF (Ba x Cu 1-x Fe 2 O 4 (x = 0.2-0.8)) samples prepared via the hydrothermal method reveal the nanorod/nanofibers in the morphology as reported by Naresh et al [10,11]. BVS Reddy et al [12,13], synthesized the ALTBT nanocomposites consisting of the nanorods-like structures. Herein, the PLCT, PCLT, BCLF, and ALTBT nanostructures show the complete nanofiber/nanorods at high percentage of La +3 cations, whereas the BCF samples perform the same nature at high percentage of Ba +2 cations of high ionic radii.…”

“…These nanocomposites are prepared by the hydrothermal process and depending on the composition the structure can be changed which is observed based on the X-ray diffraction analysis. This compound (1−x) (Al 0.2 La 0.8 TiO 3 ) + (x) (BaTiO 3 ) (x = 0.2-0.8) exhibits very good electrical properties and several advantages over other composites such as X-ray density (~11.210 g/cm 3 ), surface area (~62.29 m 2 /g) electrical conductivity (~4.21E − 05 S/cm at 1 MHz) and dielectric constant of 62,768 at 1 kHz [31]. The TiO 2 nanofibers are prepared by electrospinning used in dye-sensitized solar cells as an anode material.…”

In this review work, we highlight the origin of morphological structures such as nanofibers/nanorods in case of various materials in nano as well as bulk form. In addition, a discussion on different cations of different ionic radii and other intrinsic factors is provided. The materials (ceramic titanates, ferrites, hexaferrites, oxides, organic/inorganic composites, etc.,) exhibiting the nanofibers/nanorods like morphological structures are tabulated. Furthermore, the significance of nanofibers/nanorods obtained from distinct materials is elucidated in multiple scientific and technological fields. At the end, the device applications of these morphological species are also described in the current technology.

The polycrystalline Sm2/3Cu3Ti4O12 (SCTO) ceramics have been prepared by solid‐state reaction. The crystallinity of the compound has been investigated by Rietveld refinement which has revealed a cubic structure with space group Im3. It is observed that at low frequencies, SCTO ceramic exhibits tremendously high values of dielectric permittivity ε′, larger than 32,000, at room temperature. Two distinct, thermally triggered, dielectric relaxations have been noted. This mechanism has been confirmed through impedance analysis of the ceramics. The complex impedance plane shows three semicircles, which confirm the existence of two dielectric relaxations in SCTO ceramics. In general, the electrical as well as dielectric behavior of SCTO ceramics are seen to be reasonably analogous to those of CaCu3Ti4O12 (CCTO) ceramics. The emergence of the enormous dielectric constant in SCTO ceramic is accredited to the combined effect of polarization both at the sample‐electrode interface as well as at the insulating grain boundary interface. The SCTO ceramics are identical to the CCTO ceramics in their structure and composition and hence, as the above results indicate, the IBLC effect mechanism, originally put forward for CCTO ceramics, is furthermore plausible to account for the mammoth values of dielectric constant in SCTO ceramics.

The present work aims to synthesize Zinc copper Ferrite (ZCF) Nanoparticles (NP’s) by using low cost hydrothermal technique. Afterwards, the prepared ZCF NP’s characterized by various techniques. In this connection, the presence of metal oxide bonds were confirmed by Fourier transform infrared spectroscopy (FTIR), Further, X-ray diffraction (XRD) analysis revealed the presence of cubic spinel structured NP’s with single phase. The average particle and surface morphology is studied by using field emission scanning electron microscope (FESEM). In addition, the antimicrobial studies carried out against Proteus vulgaris. confirmed that the prepared NP’s exhibit excellent antimicrobial performance against different pathogenic gram-positive and gram-negative bacteria.
