| Research Abstract |
The main purpose of this research is to clarify the complicated mechanism for particle-fluid separation of various soft nano-colloids. Ultracentrifugation and membrane separation properties of protein as soft nano-colloids were clarified. It was revealed that the deformability of soft nano-particles play a major role on deliquoring properties such as the cake permeability, compared with experimental results of hard nano-particles,. Moreover, a multi-stage creep model has been newly developed in order to elucidate the complex consolidation behaviors of soft materials.
