Research Abstract |
From xylem parenchyma cells in trees that can supercool to -40C during winter, we identified a several kinds of flavonol glycosides and hydrolysable tannins. Based on such results, we could also identified more than 50 kinds of flavonol and tannin-related compounds that promoted supercooling of water. We also tried to use these supercooling-promoting substances as novel materials that inhibit freezing of water.
