“…The Nyquist plot elaborates on the presence of grain, grain boundary, and electrode effect in the material. 41,42 The ZSIMPWIN(2.0) relates the experimentally perceived values with the tted observed values. In this spectrum, the semicircular spectrum was observed aer an increase in temperature.…”

“…This unique combination of conditions facilitates the nucleation and growth of NPs with controlled size, shape, and crystallinity. 2 Another significant benefit of the hydrothermal approach is its scalability, making it feasible for both laboratory-scale research and large-scale industrial production. The process parameters can be adjusted and optimized to tailor the NP characteristics according to specific applications.…”

As nanotechnology gains popularity in medicine, there is a growing concern that small nanoparticles (NPs) could accumulate and penetrate deep into the human body, posing potential risks to various organs. To ensure safe usage and assess potential hazards, it is crucial to conduct a toxicological evaluation of ZnO NPs on human organs such as the kidney. The present study involved the synthesis of ZnO NPs by using the hydrothermal method. Pure and crystalline phase was confirmed by X‐ray diffraction (XRD). The SEM images displayed less agglomerated surface morphology, implying that the NPs were distributed relatively evenly and exhibited a plate‐like shape. Two pathogenic fungi Fusarium incarnatum and Aspergillus niger were isolated from the capsicum and tomato, respectively, and identified through morphological and molecular analysis. The antimycotic property of synthesized ZnO NPs were examined against Fusariumincarnatum (MT682502) and Aspergillus niger (MT675916) and showed decreased microbial growth after 9 days of incubation. The toxicological evaluation of ZnO NPs on a human embryonic kidney (HEK293) cell line showed 88% cell viability with 10 μg/ml, leading to the safe use of ZnO NPs.

This article reports the fabrication (synthesis) and characterizations (structural, microstructural topographic surface, dielectric, transport, impedance, current‐voltage, and resistive properties) of a complex lead‐free defect perovskite material of composition LiBiFeMnO5. A preliminary structural investigation of the X‐ray diffraction (XRD) pattern using N‐TREOR09 methods shows monoclinic symmetry. The scanning electron microscopic spectrum examines the sample’s microstructural topographic surface, fractal study, and roughness (using the standard ISO25178). The analysis of Maxwell‐Wagner dielectric dispersion, relaxation, and transport mechanisms are investigated utilizing dielectric, impedance, and conductivity spectrum accumulated within the experimental frequency of (1 kHz – 1 MHz) at different temperatures (30–500 ˚C). A non‐overlapping small polaron tunnelling (NSPT) conduction mechanism and correlated barrier hopping (CBH) mechanism in the material have helped to understand its conduction phenomena. The Ohmic and space charge limited conduction (SCLC) mechanisms have been investigated by the slope of the logarithmic electric field (E) and current density (J). The thermistor constant (β) is determined to be 1982.87. The temperature coefficient of resistance (TCR) is found to be ‐0.00419, which may be suitable for negative temperature coefficient (NTC) thermistors, sensors, and other related devices.This article is protected by copyright.
