| Research Abstract |
We have studied the Ludwig-Soret effect, which means the development of the concentration gradient due to the applied stable temperature gradient, for polymer solutions in order to obtain deeper understandings for the molecular mechanisms of the Ludwig-Soret effect. This research project aims to contribute to develop non-equilibrium thermodynamics and polymer physics. We have selected several water-soluble polymers systematically to reveal the effects of molecular interactions through hydrogen bonds. The experimental studies has been carried out by means of thermal diffusion forced Rayleigh scattering. Additionally, the project has revealed a new insight about the research field of life science due to systematic studies on biological macromolecules under the non-equilibrium conditions.
