Elucidation of Mechanism for Ultraprecise Separation of Soft Nano-Colloids

本研究的主要目的是阐明各种软纳米胶体颗粒-流体分离的复杂机理。阐明了蛋白质作为软纳米胶体的超速离心和膜分离特性。通过与硬质纳米颗粒的实验结果对比，揭示了软质纳米颗粒的变形性对滤饼渗透性等脱水性能的影响。此外，为了解释软材料的复杂固结行为，还建立了多阶段蠕变模型。

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.
