\thispagestyle{empty}

First and foremost, I would like to express my deepest gratitude to my supervisors, \textbf{Prof. Valentina Gatteschi}, \textbf{Prof. Marco Domaneschi}, and \textbf{Prof. Valentina Villa}, for their invaluable guidance, continuous support, and patience throughout my master's study. Their technical insights and advice were essential for the completion of this thesis.

I dedicate this work to my family, who have been my source of strength. To my father and mother, thank you for your endless love, your sacrifices, and for believing in me every step of the way. To my sister, thank you for your constant support, your kindness, and for always cheering me on when things got difficult. I could not have reached this milestone without you.

I would also like to thank my university colleagues and lab partners. Your collaboration and camaraderie during our university coursework and laboratories made the journey of this Master's degree a memorable and enriching experience.

Finally, my sincere thanks go to my friends for their encouragement, their humor, and for always being there when I needed a break.
