In this research, Molecular Dynamics (MD) simulations were conducted to explore the temperature effect on the microstructure and phase transition of the Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the material's phase transition switches from crystalline to liquid and vice versa.

In this study, spinel ferrite nanoparticles CoFe2-xLaxO4 (x = 0, 0.025, and 0.05) were successfully synthesized via a simple co-precipitation method using a 5% NaOH solution as a precipitating agent. The physicochemical properties of the materials, annealed at 850 °C for one hour, were characterized using powder X-ray diffraction (PXRD), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and vibrating-sample magnetometry (VSM) at room temperature.
