Atomistic computer simulations of material behaviors

Potential development for atomistic simulations of glass and ceramics

Interatomic potentials are critical to atomistic simulations of materials. Our group develop interatomic potentials for silicate, borosilicate, and phosphosilicate glasses, as well as reactive potentials to study glass-water interactions, through empirical fitting and QM calculations.

Glass structure and structure-property relations

Glass materials have many unique properties such as optical, dielectric, mechanical and others but the structure of glass lacks long range order hence defies any single experimental characterizations. We utilize both classical and ab initio based materials simulations to study the complex glass structures and structure-property relations of glass materials.

Functional glasses and glass-ceramic materials

Glass for nuclear waste disposal

Vitrification is a widely accepted method to immobilize nuclear waste to provide clean energies and ensure safe environment. We investigate borosilicate, aluminosilicate and other glasses for waste applications by using simulations and experiments. Particularly, we try to understand the structures of these glasses and how they interact with the environment (or the corrosion behaviors).
