| Research Abstract |
We carried out measurement of temperature field for the solution of antifreeze protein under unidirectional freezing using near-infrared light. Also, we estimated protein concentration with fluorescence microscopy. We found that noticeable heat flux exist in the direction perpendicular to the ice growth direction in the serrated interface. This heat flux was due to the high concentration regions of antifreeze protein. The interface temperature for the mixed solution of antifreeze protein and sodium chloride is lower than the sum of the interface temperature for antifreeze protein solution and the interface temperature for sodium chloride solution. We obtained the results of molecular dynamics analysis, which was consistent with the measured result.
