Outline of Final Research Achievements

We constructed Thermal Diffusion Forced Rayleigh Scattering System and applied it to thermophoresis phenomena of a ternary component system. We have succeeded in reproducing Lehman effect of cholesteric liquid crystals which is a typical example of nonequilibrium cross effects, and elucidated internal molecular alignment structure of liquid crystal droplets. Mechanism of Lehman effect is discussed based on angular speed of rotating droplets as a function of their radius. Furthermore, we constructed several new types of self-propelled particles by using nonequilibrium cross effects.
