Kinetic modeling

Definition

Kinetic modeling refers to the use of mathematical equations and simulations to describe and predict the dynamics of physical processes, particularly focusing on the rates of reactions and changes in systems over time. This approach is essential for understanding how various factors influence the behavior of materials under different conditions, especially during transformations such as crystallization or phase changes. By applying kinetic modeling, researchers can gain insights into mechanisms, optimize processes, and develop better materials in fields like crystallography.
