| Outline of Final Research Achievements |
We carried out experiments on the freezing of water with antifreeze peptide and cellulose nanofibers in a narrow space between two cover glasses and inside a mini pipe. The results in the case of unidirectional freezing showed that by adding electric fields the ice growth rate in the antifreeze peptide solutions decreased. Although the interface temperature decreased in water with the cellulose nanofiber, there was no effect of electric field addition. In the case of mini pipe flow, irrespective of the flow velocity, the supercooling temperature decreased only for the peptide solutions. Even if the electric fields were imposed, the supercooling was not enhanced for the water flow with antifreeze peptide and cellulose nanofibers. Finally, irrespective of the flow velocity of pure water, the ice growth was delayed by coating the antifreeze peptide on the inner surface of the pipes.
