Summary: In this study, ferrimagnetic nanoparticles (FMNPs) were synthesized using different wet chemical synthesis methods. The influence of different synthesis methods on the structural and magnetic properties of FMNPs was explored. The results showed that FMNPs obtained through chemical co-precipitation method exhibited a stable cubical shape with smaller size, while FMNPs prepared by hydrothermal method showed higher magnetic strength and suitable particle size distribution. Additionally, the chemical co-precipitation method was found to be more cost-effective and time-efficient.

Summary: The study compares the physicochemical, optical, electrical, and photodetective properties of earth-abundant quaternary Cu2FeSnS4 (CFTS) nanoparticle-based films synthesized via different methods. It is found that the synthesis process significantly impacts the morphology, chemical composition, optical properties, electrical properties, and performance of CFTS nanoparticle-based visible photodetectors. Hydrothermal-synthesized CFTS nanoparticle-based detectors exhibit photoinactive properties, while solvothermal-synthesized devices have higher photosensitivity.

Summary: In this work, ZnFe2O4/reduced graphene oxide (rGO) nanocomposites were successfully prepared using a facile microwave hydrothermal process. The influence of rGO content on the morphology, structure, and electrochemical performance of the ZnFe2O4/rGO nanocomposites was systematically investigated. The as-prepared ZnFe2O4/rGO electrode with 44.3 wt.% rGO content exhibited a high specific capacitance of 628 F g(-1) and long cycle life of 89% retention over 2500 cycles at 1 A g(-1). This work provides a new process for synthesizing binary transition metal oxide and developing a new strategy for realizing high-performance composites for supercapacitor electrodes.

Summary: This study presents a novel synthesis method for producing hydrophilic and almost spherical NaY(MoO4)(2) nanoparticles, which can be used for preparing nanophosphors with intense luminescence by doping with lanthanide cations. The effects of cation doping levels on luminescent properties were analyzed to find the optimum phosphors. The performance of these nanophosphors and undoped system for photocatalytic degradation of rhodamine B was also evaluated.

Summary: The research aims to engineer desired molecular sp(2) structures in graphene oxide by controlled oxidation of graphite powder, in order to achieve tunable chemical and microstructural properties for optoelectronics or sensing applications. Experimental results show that different concentrations of potassium permanganate and potassium hydroxide can change the microstructural and chemical properties of GO, leading to significant enhancement of photoluminescence and introduction of additional electronic energy levels for tuning the functional properties of GO.

Summary: This study found that long-term cycling does not significantly affect the structure and morphology of carbon electrodes, but surface chemistry undergoes significant changes, including the chemical absorption of chloride counter anions at point defects on the graphitic surface. Vanadium cation plays an important role in the counter anion-carbon surface interaction.

Summary: This study aims to synthesize nanostructured materials using a new method, which is environmentally friendly and can produce materials with fluorescence and/or plasmon band for various applications. Cobalt tungstate nano-particles were prepared using the proteic sol-gel method, with two types of polymerizing agents. The synthesized materials exhibited different crystal symmetries and particle sizes, and the process was optimized to achieve the best synthesis conditions. Furthermore, the nanostructures showed maximum emission and absorption at 468 nm and 410 nm, respectively, indicating their potential in luminescent sensors.

Summary: Nano-V4O9 plate-like morphology was successfully synthesized by hydrothermal treatment using V2O5 as vanadium source and 3-amino-1-propanol as reducing and structure-directing agent. The nano-V4O9 exhibited high crystallinity and had a uniform plate-like morphology with a thickness of approximately 46 nm. The formation mechanism of the nanoplates was proposed. The optical properties of the synthesized samples were investigated and the photoactivity of V4O9 nanoplates was evaluated in the degradation of methyl orange under solar irradiation.
