Outline of Final Research Achievements

Professor de Gennes, who received Nobel Prize in Physics for his pioneering research in Soft Matter, extracted simple physical essences from various problems by a unique method. This method, in which many details are ignored, is compared to Impressionism in painting and is called the impressionist spirit in physics. In this research, in order to show the wide utility of this method, we developed studies on wetting phenomena and conducted various researches with the aid of many researchers and students. In particular, we studied the penetration dynamics of liquid into textured surfaces, also observed on the legs of an animal, and several systems of granular materials, and so forth. Our results provide simple and intuitive understandings, which can be useful for researchers in industry or in related fields. Part of the results also led to the application of domestic and international patents.
