Ice Nucleation and Antinucleation in Nature
Cryobiology, 2000Plants and ectothermic animals use a variety of substances and mechanisms to survive exposure to subfreezing temperatures. Proteinaceous ice nucleators trigger freezing at high subzero temperatures, either to provide cold protection from released heat of fusion or to establish a protective extracellular freezing in freeze-tolerant species.

DURING recent years ice-nucleation by some organic substances has been investigated with increasing interest in fundamental, as well as in practical, fields. Some steroids can nucleate ice crystals at temperatures as high as − 1° C when prepared by thermal recrystallization1,2. One of the amino-acids3 is reported to nucleate ice at − 4.5° C.

SUMMARYIce‐nucleating capability of the kiwifruit vine, Actinidia deliciosa, was examined. Pseudomonas viridiflava, present as an epiphyte on the vine, was an effective icenucleating agent. The presence of other sources of ice nuclei on the surface of the vines, leaves and fruit, which could not be inhibited by anti‐bacterial agents, was also ...

Effective Nucleation Size for Ice Crystallization
Journal of Chemical Theory and ComputationDespite the apparent simplicity of water molecules, the kinetics of ice nucleation under natural conditions can be surprisingly intricate. Previous studies have yielded critical nucleation sizes that vary widely due to differences in experimental and computational approaches.

Publisher Summary The phase transitions of water to ice have crucial consequences in the atmosphere and in biological systems. Studies of the processes even with pure water face many obstacles, and the heterogeneous processes are yet more complex.
