چکیده انگلیسی
We have observed the solution structure of the supercooled sodium acetate aqueous solution, especially for the existence of clusters and their crystallization process, by means of Scanning electron microscopy (SEM) with the freeze replica method. Microscopic internal structure of sodium acetate trihydrate crystals mainly constitutes the aggregates of 100-200Â nm in diameter, which consists of the clusters of 10-20Â nm in diameter. In the case of a supercooled aqueous solution of 293Â K, two types of aspect in the vitrified aqueous solution mainly exist: one is the clusters of 10-20Â nm in diameter; the other is the smooth zone without any structure. At 263Â K, the relationship among clusters of 10-20Â nm and their aggregates of 100-200Â nm was clearly observed. The aggregates construct the three-dimensional loose networks, which are not fully packed, different from the crystal.
