Research Interests

My research interests in general concern wet-chemical synthesis and colloidal processing of inorganic materials. In particular metal carbonates, oxalates, and binary and tertiary metal oxides. In particular, I specialize in the determination of the relationships between early processing stages of the wet-chemical process (when the amorphous species are formed in the solvent environment), and the influence of these early stages onto the microstructure and nucleation of the crystalline materials under out-of-equilibrium conditions (e.g. upon drying) or upon high-temperature processing.

Currently, I work as a Post-doctoral Fellow (Experienced Resaercher, ER) within the Marie Curie MINSC ITN. The goal of my project is to derive molecular level knowledge regarding the effect and role of organic inhibitors (sulphonates and phosphonates) on the formation of calcium carbonates and oxalates. The precipitation of these phases induce scaling problems which affect the life-time of feed pipes (i.e., pipe clogging, corrosion, etc.) and thus reduce flow performance and efficiency in a variety of industrial processes (i.e., oil and food production). The aim of this project is to use state-of-the-art synchrotron-based scattering and diffraction techniques (Small and Wide Angle X-ray Scattering, SAXS/WAXS) to follow the nucleation and growth of these phases in the absence and presence of the inhibitors and as a function of changing pH, saturation and T conditions. The synchrotron dataset is complemented by high-resolution microscopy (Field Emission Gun – Scanning Electron Microscopy, FEG-SEM / High-Resolution Transmission Electron Microscopy, HR-TEM), as well as infrared spectroscopy.
