Several samples are prepared with different annealing temperatures and investigated in different atmospheres to recognize magnetic and electrical properties. A xerogel powder of bismuth ferrite is synthesized by the sol-gel route. The powder then anneals at 500, 600, 700, and 800 °C to form a nanostructure. X-ray diffraction analysis confirms that the annealed samples are in rhombohedral structure with R3c space symmetry and show a significant increase in crystal size and reduction in lattice strain with increasing annealing temperature. FESEM reveals the microstructural features of annealed nanoparticles which represent the conversion of spherical to cubic morphology with annealing temperature. Vibrating sample magnetometer investigations were conducted as a function of annealing and surface (300, 200, 80 K) temperatures. Insignificant variations of saturation magnetization are detected with surface temperature, but considerable degradation is observed with increasing annealing temperatures. The band-gap energy of bismuth ferrite nanoparticles annealed at 500, 600, 700, and 800 ºC is measured and significant escalation is observed from 1.93 to 2.06 eV.

Continuous (S1) and composition-modulated (S2) wires were fabricated by electrodeposition using porous alumina membranes as a template. Morphological characterization revealed that the total length of the wires was 8 ± 3 µm in both S1 and S2. For the composition-modulated wires, the length of the segments with the lowest and highest Cu concentrations was 1.2 ± 0.4 µm and 226 ± 65 nm, respectively. Mapping by energy dispersive spectroscopy (EDS) revealed that the concentration of copper and nickel varied along the length of the composition-modulated nanowires, while the continuous nanowires contained a relatively constant concentration of both metals. It is demonstrated that the change in Cu concentration along the wire modifies the lattice parameter, average crystallite size (D) and lattice strain (ε) of Ni. This result is pivotal for understanding the magnetic properties of the wires, as nickel is primarily responsible for the magnetic behavior of the wires. From the ferromagnetic resonance (FMR) results, the linewidth and resonance field values for samples S1 and S2 were determined. It was demonstrated that the greater deformation in the nickel lattice in NiCu nanowires increases the angular dependence of the resonance field. Furthermore, the smaller nickel crystallite size was shown to increase spin dispersion and magnetic damping, leading to complex behavior in FMR responses. Finally, it was demonstrated how Cu can influence the magnetic properties such as coercivity (HC) and squareness (MR/MS) of the wires.

The inherent characteristics of the biochar, including the porosity, surface area and conductivity, enhance the overall performance of MFCs, as well as the microbial activity such as nutrient retention and pH buffering, and promote efficient electron transfer. The current review emphasizes biochar's different sources, characteristics, and synthesis techniques. This review also discusses the application of biochar in MFC as anode and cathode, followed by its utilisation in soil amendment and bioelectricity generation.

Although, even now, their lower energy density may stall their commercialization in the portable sector, they are considered prime candidates for large scale electrochemical energy storage applications. Accordingly, advancing, establishing, and maintaining the safety of SIBs is crucial to prevent catastrophic thermal runaways and colossal financial losses to garner the trust of concerned authorities. Electrolytes play a pivotal role in the safety of batteries. Considering the above, this paper presents a comprehensive review of the progress in safe electrolytes for SIBs. It explains the various approaches employed to enhance the safety of high-risk based electrolytes and the electrochemical performance of intrinsically safe electrolytes. Moreover, a state-of-the-art review of the assembled cells/half cells employing different classes of electrolytes is also presented. Particular attention has been devoted to specifying the techniques and results, if available, of thermal stability and safety tests besides highlighting the electrochemical characteristics and performance, such as the cell capacity and cyclability, and electrolyte ionic conductivity and electrochemical stability window (ESW) of the electrolyte. Finally, challenges and future research directions have been summarized and recommended.

The greatest effect on bacterial viability was related to the ZnO factor. The synthesis of alginate/MMT/ZnO nanocomposites with desirable conditions was confirmed using various analyses.
