The primary goal of this research area is to greatly advance fundamental science and technology, which include exploration of phase-interfacial energy conversion/transport phenomena and creation of high-performance phase interfaces, in order to achieve ever more efficient energy utilization and thus to realize an enriched sustainable society.
Specifically, we take up the challenge of creating phase interfaces with significantly reduced energy losses and/or those for highly efficient energy use by deepening fundamental theory and control/optimization methodology of phase interface phenomena. To accomplish these goals, it is indispensable to establish analytical and design techniques integrating nano-, meso- and macro-scales, as well as theoretical methods for the control and optimization of phase interface structures.
Furthermore, it is important that the results of such cutting edge fundamental research should be transferred and effectively applied to the design of real equipment and systems, leading to dramatically improved performance, reduced carbon emissions and lower costs. The ultimate goal of this research area, therefore, is to elucidate energy conversion and transport mechanisms at phase interfaces in order to enable highly efficient energy use; to develop measurement, modeling and simulation methods for integrative analysis and design of phase interface phenomena at multiple scales; to establish mathematical methods for the control and optimization of phase interface structures; and to realize highly functional phase interfaces that allow for theoretically possible maximal performance in actual devices and equipment. To meet these goals, we encourage integrated challenges that go beyond the bounds of existing scientific disciplines and combine the knowledge gained in different fields.
