Three Most Important Scientific Discoveries (Experimentally Confirmed)
Current Research ActivitiesResearch activities in our group are mainly focused on three areas in Physical Chemistry and Materials Chemistry:
- Chemical Physics of Phase Transition and Interfaces: Computational and theoretical studies of liquids and confined fluids, water (ice) in particular, and related topics such as interfaces, hydrophobicity, wetting, melting, surface tensions, nucleation, and solvation.
- Inorganic Clusters and Surface Catalysis: Structural evolution of clusters (in particular Au, Si, B and water), and heterogeneous nanocatalysis.
- Materials Chemistry and Nanoscience: Computer-aided design and study of nanostructured materials (in particular, two-dimensional atomic-layer materials).

We employ University of Nebraska-Lincoln Supercomputing facility to carry out virtual experiments and explore behavior of matters under extreme conditions, e.g. under high temperature, high pressure, or in highly confined environments, in which real-world experiments may be impractical or inaccessible. As an example, we have revealed several new forms of ice and silicon, solely based on large-scale computer simulations. Below, we show a snapshot of 2-dimensional "Nebraska Ice"; and a snapshot of 1-dimensional single-walled hexagonal silicon nanotube.
Other research activities in my group include computer-aided molecular and materials design. Below, we show a golden "buckyball" Au16. In short, the only limitation is your imagination!
