This study presents a comprehensive exploration of numerical and mathematical models designed to elucidate the formation processes of nanofilms. Nanofilms, with their unique properties and applications in various fields such as electronics, optics, and material science, require a detailed understanding of their growth mechanisms to optimize their performance and functionality.

We develop and apply mathematical models to describe the key processes involved in nanofilm growth, including nucleation, surface diffusion, and film deposition. These models are based on partial differential equations that capture the spatial and temporal evolution of film thickness and composition. To complement the theoretical framework, we employ numerical simulations to solve these equations and visualize the formation dynamics under various conditions. Our study demonstrates how factors such as deposition rate, substrate temperature, and material properties influence the morphology and uniformity of nanofilms. We present detailed results from simulations that illustrate the impact of these parameters on film growth and quality. The models and simulations are validated against experimental data, ensuring their accuracy and relevance.

The incorporation of nano-sized Calcium Copper Titanate (nano-CCTO) fillers into epoxy composites has been shown to significantly impact their dielectric properties. This study investigates the influence of varying concentrations of nano-CCTO on the dielectric constant of epoxy composites, focusing on understanding how these fillers alter the electrical behavior of the matrix material. Nano-CCTO particles, known for their high dielectric permittivity and low dielectric losses, were synthesized and incorporated into an epoxy resin at different weight fractions. The dielectric properties of the resulting composites were characterized using impedance spectroscopy over a broad frequency range. The study reveals that the dielectric constant of the epoxy composites increases with the addition of nano-CCTO fillers, with the most pronounced effects observed at specific filler concentrations. The observed improvements in dielectric properties are attributed to the enhanced polarization effects and the formation of a percolation network within the composite matrix. These findings suggest that nano-CCTO fillers can be effectively used to tailor the dielectric properties of epoxy composites for advanced electronic and electrical applications.
