1). Assembly of nanoparticles as large molecules

Nearly monodisperse nanoparticles can be viewed and described as large molecules. Our research showed that suspensions of quasi-monodisperse nanoparticles act like molecular solutions [H. Yan et al. PRL 109, 095501, (2009)]. High pressure can continuously modify the size and the structure of materials. We are working on the dissolution, aggregation, nucleation and the solubility phase behavior of nanoparticle large molecule system under high pressure and high temperature.

2). Nanomaterials in supercritical fluid

Developing an understanding of the reaction processes occurring at the surface–fluid interface at the atomic level of nanostructured materials in high-temperature aqueous environments is necessary for establishing general principles of behavior of nanomaterials operating in such extremes. Investigations of the reactivity, adsorption, precipitation, structure and other properties of metal ions on nanoparticles in supercritical fluids heated are made in our lab and synchrotron light sources.
