    Abstract: This internship focuses on advancing nanoparticle synthesis through real-time monitoring using in situ small-angle X-ray scattering (SAXS). The goal is to establish a precise control system for nanoparticle properties by creating an automated synthesis setup with a feedback loop between SAXS measurements and synthesis parameters. The intern will work on synthesizing model nanoparticles (SiO2) with sub-nanometer accuracy, analyzing SAXS patterns, understanding the impact of operational parameters on nucleation and aggregation rates, and ultimately building a feedback control loop for producing nanoparticles with predetermined sizes.
