Elucidation of Mechanism for Ultraprecise Separation of Soft Nano-Colloids

本研究的主要目的是阐明各种软质纳米胶体的粒-液分离的复杂机理。阐明了蛋白质作为软质纳米胶体的超离心和膜分离特性。结果表明，与硬纳米颗粒相比，软纳米颗粒的变形能力对滤饼渗透率等脱液性能起主要作用。此外，一个多阶段的蠕变模型已被新发展，以阐明复杂的固结软材料的行为。

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.
