Synthesis and spectroscopic characterization of zinc ferrite nanoparticles
Arora, Shefali,Nandy, Subhajit,Latwal, Mamta,Pandey, Ganesh,Singh, Jitendra P.,Chae, Keun H. Techno-Press 2022 Advances in nano research Vol.13 No.5
Synthesis approaches usually affect the physical and chemical properties of ferrites. This helps ferrite materials to design them for desired applications. Some of these methods are mechanical milling, ultrasonic method, micro-emulsion, co-precipitation, thermal decomposition, hydrothermal, microwave-assisted, sol-gel, etc. These methods are extensively reviewed by taking example of ZnFe<sub>2</sub>O<sub>4</sub>. These methods also affect the microstructure and local structure of ferrite which ultimately affect the physical and chemical properties of ferrites. Various spectroscopic techniques such as Raman spectroscopy, Fourier Transform Infrared spectroscopy, Ultra Violet-Visible spectroscopy, Mossbauer spectroscopy, extended x-ray absorption fine structure, and electron paramagnetic resonance are found helpful to reveal this information. Hence, the basic principle and the usefulness of these techniques to find out appropriate information in ZnFe<sub>2</sub>O<sub>4</sub> nanoparticles is elaborated in this review.

The present research aimed to analyze the nematicidal and insecticidal activity of the essential oil obtained from the fruits of Zanthoxylum armatum collected from Gumma village of Dharchula and Chandak village of Pithor agarh. After extraction via hydro distillation, the essential oils were subjected to GC–MS for their compositional analysis. A total of 10 and 13 components were identified for the Dharchula and Pithoragarh collection respectively. Linalool (32.86 %) was the major component in collection from Dharchula whereas it was totally absent in that of collection from Pithoragarh which has trans-sabinene hydrate (11.7 %) as its major component. Essential oils were tested against Meloidogyne incognita for their nematicidal activity and inhibition of egg hatching in laboratory conditions. It was found that the activity of Z. armatum from Dharchula shows high mortality of Meloidogyne incognita and more inhibition to the egg hatching. When tested for insecticidal activity against Lipaphis erysimi, collection from Dharchula presented stronger activity compared to Pithoragarh collec tion as shown by their LC 50 values 0.006 and 0.165 µL/mL respectively after 36 hrs. The in silico PASS study and molecular docking study was conducted to screen the nematicidal and insecticidal potential of the major com ponents on acetylcholinesterase receptors. Results showed good binding affinities and attributed the strongest inhibitory effect to verbenone for the target protein.
