| Outline of Final Research Achievements |
This study aimed to investigate the structure and dynamics of water and aqueous functional materials using advanced techniques such as synchrotron radiation, neutron, thermal analysis, and terahertz spectroscopy. The goal was to understand the mechanism behind the expression of functions and establish scientific principles for optimal design. The research focused on improving the accuracy and measurement environment of these advanced techniques to clarify the relationship between the structure and dynamics of interfacial water and its various functions, including biocompatibility, ion selective permeability of self-assembled liquid crystalline membranes, adhesive properties, and protein stabilization. The study provided insights into the unique structure and dynamics of water adsorbed on specific functional groups and its surrounding water. This knowledge can be used to guide materials design for predicting or enhancing their functionality.
