“…Magnetic nanoparticles have increased significant enthusiasm for different areas, for example, ferrofluids, magnetic drug transportation, magnetic separations, magnetic data storage devices, magnetic resonance imaging (MRI), and magnetic fluid hyperthermia treatment for malignant growth [1][2][3][4][5][6][7][8]. Magnetic nanoparticles are alluring catalyst since they can be isolated from the response medium by applying an outside magnetic attractive field.…”

A profoundly effective magnetically recoverable nano zinc ferrite nanocatalyst was fabricated by means of sol-gel auto ignition strategy. The synthesized nanocatalyst has been completely portrayed by standard techniques for structural, morphological, compositional, surface, magnetic, dielectric, optical and photoluminescence properties individually. The x-ray diffraction pattern affirmed the arrangement of cubic spinel structure with an average crystallite size of 21 nm. FE-SEM images uncovered the circular morphology with nanometric average grain measure (37 nm). The surface area, pore volume and pore radius was observed to be 39.812 m 2 g −1 , 3.41 cc g −1 and 1.34 nm individually from BET analysis. VSM investigation demonstrated the superparamgnetic nature of the prepared sample with moderate magnetization value and negligible coercivity. The optical band gap deduced from UV-vis spectra was observed to be 2.098 eV. Every one of these properties of zinc nanoferrite makes them brilliant contender for microwave radiation absorption. Further, a proficient and versatile microwave irradiated solvent free synthesis of chalcone derivatives has been developed using prepared zinc nanoferrite catalyst. The remarkable highlights of this new protocol are solvent free reaction, economical cheapness, eco-friendliness, high yields, reduced reaction times and easy recovery and reuse of zinc ferrite nanocatalyst.

“…For this purpose, the heating rate was kept as 10 °C per minute in the nitrogen atmosphere from 25 °C (room temperature) to 1000 °C. Fourier Transform Infrared (FT-IR, Bruker Germany, Vertex 70 model) spectra were recorded to affirm the chemical changes in the range of 500-4000 cm −1 which gave the evidence about the numerous chemicals bonding such as Si-O-Si network, -OH, Si-OH, C-H-CH 3 , and Si-C [23]. High-Resolution Field-Emission Scanning Electron Microscopy technique (Model: FEI Quanta 200F) with EDS was used to analyze the microstructure and elemental mapping respectively of aerogel samples [24].…”

This work demonstrates the synthesis of hydrophobic silica aerogels from silicic acid with pH variations by using a costeffective and safe ambient pressure drying process. The work aims to evaluate the effect of pH variation on physicochemical properties of silica aerogels by standard techniques. In the present investigation, we have selected hexane as the solvent and trimethylchlorosilane/hexane was used to perform the surface modification of wet gel in order to elude the contraction and disintegration of gel association subsequent to a drying process. The effect pH on gelation in the form hydrolysis and condensation as well as on amorphous structure, physical properties such as density, thermal stability, surface area, pore-volume, pore radius, optical transmittance were investigated. FTIR spectroscopy was used to confirm the silylation (surface modification) of the prepared silica aerogel samples. Water contact angles were measured to verify the hydrphobic behaviour of all the samples. Among the prepared pH varied samples, the sample having pH ~ 5 shows better results such as high optical transmittance, thermal stability, hydrophobicity and high surface area.

“…Magnetic nanoparticles already gained significance in a variety of fields, which include ferrofluids, magnetic separations, magnetic drug delivery, magnetic data storage systems, magnetic resonance imaging (MRI) and so on [1][2][3][4][5][6][7][8]. Magnetic nanoparticles are promising catalysts because they can be separated from the response medium by adding a magnetic attractive field from the outside.…”

Zinc ferrite (ZnFe2O4) nanoparticles were prepared by combustion method. The FT-IR, XRD and SEM with EDS were used to characterize the prepared sample. The characterization results confirm the successful synthesis of ZnFe2O4 nanoparticles with the particle size range of 24 – 30 nm. The temperature dependent DC conductivity of the sample has been studied in the temperature range 30-175 °C and AC conductivity was investigated between the frequencies of 10 Hz and 10 MHz. DC conductivity of the sample was increased while increasing temperature and AC conductivity was increased as the frequency increased.
