Xiaoxu Li’s research focuses on thermodynamics and dynamics inherent in solid-liquid interactions. He is currently fascinated by the nonclassical nucleation, growth, and dissolution by using edge-cutting technologies to characterize, understand, and model these behaviors. Li is focused on leveraging the insights and expertise gained from natural processes for industrial applications. This includes critical areas like nuclear waste management, CO2 capture and storage, and the recovery and purification of essential minerals.
