Novel alkali (K, Na) metal-organic precursors and sol-gel growth of KNN
Based at the University of Catania / INSTM, under the supervision of Prof. Graziella Malandrino

"I completed both my Bachelor’s and Master’s degrees in Chemistry (Molecular Science) through a joint program at the University of Amsterdam and Vrije Universiteit. During my Master’s, I focused primarily on Physical Chemistry courses due to my interest in understanding the fundamental physical properties of materials and molecules, as well as exploring how they can be enhanced. For my Master thesis, I traveled to Bologna to investigate the photophysical properties of doped Copper Indium Sulfide quantum dots. This experience deepened my interest in fundamental research and ultimately led me to pursue a PhD. In my current role within the DC1 position of the HINA project, supervised by Prof. Malandrino at the University of Catania, we aim to synthesize novel metal-organic precursors of Na and K. These precursors will be used for the deposition of KNN thin films on various substrates using sol-gel and chemical vapor deposition methods. This project excites me as it offers the opportunity to understand the entire process, from synthesis to application, allowing me to specialize in multiple aspects of material development and the requirements for deposition techniques."

Hosted at the FEMTO-ST Institute / Université Marie et Louis Pasteur, supervised by Prof. Ausrine Bartasyte

"I was born in Rostov-on-Don, Russia. Since childhood, I have been deeply interested in physics, mechanics, and optics—passions that later shaped my professional path. In 2016, I began my Bachelor’s studies in Applied Physics at SFedU in my hometown. From 2018, I worked on thin ferroelectric niobate films (perovskite and tungsten bronze structures), producing them by RF sputtering and characterizing them using XRD and atomic force microscopy. In 2020, I moved to St. Petersburg to pursue my Master’s degree at ITMO University. There, I synthesized elpasolite-type nanocrystals using colloidal hot-injection, purified them, and characterized their optical properties. I also developed down-conversion LEDs with a conversion layer based on these nanocrystals. After graduation, I continued my research at ITMO, synthesizing carbon nanodots (CNDs) hydrothermally, characterizing them optically, and developing responsive CND-based sensors for solvent polarity and acidity. I also fabricated polymer-functionalized CND-based LEDs with direct charge injection, performing all fabrication steps, including photoresist processing, ITO etching, spin-coating, and thermal evaporation In 2025, I moved to Besançon to continue my research career internationally and joined the MSCA DN HINA project at the FEMTO-ST Institute. My current research focuses on the growth and optimization of epitaxial and textured KTN thin films via DLI-CVD."

"I am Diana, a PhD student within Leibniz Institute for Crystal Growth (IKZ) within the University of Humboldt in Berlin—a city with its own famously fragmented past. Ironically, I come from another place that knows a thing or two about being divided between empires—sunny, mountainous Armenia. Since I was young, I’ve been fascinated by how we can make computers faster and more secure. This interest led me to do my Bachelor’s thesis in quantum computing at Yerevan State University in Armenia. Later, during my Master’s at Université Bourgogne Franche-Comté, I became interested in neuromorphic computing and wrote my thesis on that topic. I continued exploring it at the University of Groningen in the Netherlands, where I also gained experience in materials science. Eventually, I joined the HINA project, working on freestanding KNN/KTN films and their potential in advanced electronics under the supervision of Dr. Jens Martin. Outside the lab, I enjoy ballet, improvisation comedy, and astrology."

"As a Pakistani girl, I come from a physics background, with a strong interest in how light, materials, and energy interact. During my bachelor’s studies, I synthesized a novel vanadate material, Cu₂V₄O₁₁, which I later used to successfully develop a hybrid Zn-ion battery–supercapacitor system. This project introduced me to experimental research and strengthened my curiosity for linking materials to device performance. For my MPhil in Optics and Photonic Engineering, I expanded my focus to computational materials science, carrying out DFT simulations on perovskite hydrides for hydrogen storage. This experience made me a gold medalist from University of the Punjab, and gave me a deeper understanding of how electronic structure governs energy-related properties. Currently, as a Marie Skłodowska-Curie doctoral fellow (DC10) at aixACCT Systems GmbH, Germany, my research focuses on the development and validation of an ellipsometer system for characterizing electro-optic and piezoelectric materials. My work combines optical design, simulation, and experimental validation, aiming to bridge academic precision with industrial application. Outside of research, I enjoy reading, painting, and long walks. I’m particularly fascinated by black holes, super-asymmetry, and the broader questions of modern physics."
