in brackish / fresh water regions targeting interdisciplinary fusion
[ Exploratory Research: Principle Researcher ] (FY2006 - FY2007)
Rheological properties have been investigated for soft - matters including polymers, emulsions, and suspensions. Specifically, the research interest is focused on molecular / structural origins of the entanglement of polymers, moderate thinning of emulsions, and strong thinning / thickening of suspensions. The topological interaction is essential for the polymer rheology, while the interfacial energy and phase rupture dominate the emulsion rheology. The suspension rheology is governed by the inter - particle potential and hydrodynamic interaction, thereby being intimately related with particle movement and hydrodynamic phenomena occurring in brackish / fresh water regions.
Rheology, the scientific field of investigating a relationship(s) between deformation / flow and force of various materials from phenomenological and molecular points of view, is intimately related to the molecular motion and the dynamics of material transportation. This research at ISS attempts to incorporate this viewpoint of rheology into the study of brackish / plain water regions thereby constructing a starting framework of sustainability science for the dynamics of particle transportation / material circulation in these regions.
