Outline of Final Research Achievements

Pattern formations are ubiquitously observed in Nature and industrial processes. The patterns are closely related with macroscopic physical properties, thus it is important to understand the mechanism and the nature of the pattern formation. The pattern formations have been investigated for some decades, but almost researches have been performed in homogeneous and ideal conditions, however many patterns are formed in inhomogeneous Nature. Here we investigate the pattern formation under temperature gradient. The temperature gradient induces some additional but crucial effects such as Soret effects, Marangoni effects and so on. The pattern formations in soft matters are sensitive to those effects. We found that convection dynamics becomes abnormal in the gelatin solution. In addition, we found that the undulation of the membrane becomes larger at the lower temperature region in the temperature gradient.
