    • Research Topic
      • Experiments and modeling of gas hydrate systems
        Gas hydrate is one of the world’s largest reservoirs of carbon-based fuel. For gas hydrate production and the subsequent storage and transportation, it is necessary to have a good understanding of the thermodynamic and kinetic properties of gas hydrate. Current research projects included (1) both experimental work and modeling of phase behavior of gas hydrate systems; (2) development of the production technology of replacing methane hydrate by CO2.
      • Wetting behavior on micro/nanoscale patterned surfaces
        Micro/nanoscale patterned surfaces have been fabricated as well as superhydrophobic surfaces. Wetting behavior and evaporation process of a liquid droplet deposited on these patterned surfaces are explored both experimentally and theoretically to improve related applications, such as ink-jet printing, microfluidics………。
      • Physico-chemical behavior of aqueous systems containing polymers and surfactants.
        The behavior of systems containing polymer and surfactants plays an essential role in practical applications, such as detergents, foods, cosmetics, paints, pesticides and formulations of drugs. A multitude of techniques are applied to characterize and explore the structure and composition of aggregates and complexes formed by polymers and surfactants.
