Abstract Scope |
Materials structure and properties are sensitive to the tuning of processing conditions. Optimal material performance often represents a small region of process parameter space. Traditional synthesis methods struggle to characterize these spaces due to the high cost of test experiments. One such method is flame spray pyrolysis (FSP), where a plume of atomized solution combusts to produce nanoparticles for applications such as catalysis and chemical energy storage. In FSP, particle geometry and chemical/phase makeup are nonlinearly related to variables including solution chemistry, and liquid and gas flow rates. In this work, we employ Bayesian optimization (BO) to explore and optimize the processing space of FSP of silica (SiO2) nanoparticles based on in-situ optical emission spectroscopy and particle size distribution measurements. BO enables the discovery of interesting phenomena and optimizes parameter settings resulting in good performance with minimal expense. |
