Study of Supercooling Phenomena in Soil‐Water Systems Based on Nucleation Theory: Quantifying Supercooling Degree

open access: yesWater Resources Research, 2023
AbstractDetermining the minimum supercooling temperature (Tsc) of unsaturated saline soils is the key scientific problem in cold‐region agricultural and engineering, and theoretical models with good predictability are urgently needed. This study establishes a framework for pore solution freezing nucleation in unsaturated saline soils, the chemical ...

The Degree of Metallic Alloys Crystallinity Formed under Various Supercooling Conditions

open access: yesCrystals, 2023
Amorphous metal alloys play an important role in the electrical industry. Studies show the presence of an insignificant proportion of crystals in alloys that are amorphous from the point of view of X-ray diffraction analysis.

Determination of Supercooling Degree, Nucleation and Growth Rates, and Particle Size for Ice Slurry Crystallization in Vacuum [PDF]

open access: yesCrystals, 2017
Understanding the crystallization behavior of ice slurry under vacuum condition is important to the wide application of the vacuum method. In this study, we first measured the supercooling degree of the initiation of ice slurry formation under different stirring rates, cooling rates and ethylene glycol concentrations.

Crystallization in diblock copolymer thin films at different degrees of supercooling [PDF]

open access: yesPhysical Review E, 2009
The crystalline structures in thin films of polystyrene-b-poly(ethylene oxide) (PS-b-PEO) diblock copolymers were studied in dependence on the degree of supercooling. Atomic force microscopy showed that the crystalline domains (lamellae) consist of grains, which are macroscopic at low and intermediate degrees of supercooling, but of submicrometer size ...
