supercooling
undercooling

The greater the supercooling, the smaller the critical radius and the less energy needed to form it.

Does supercooling occur to an extent in all water phase changes, no matter how stable the environment?

Guth decided to solve this problem by suggesting a supercooling during a delayed phase transition.

Tye suggested that they check that the expansion of the universe not be affected by the supercooling.

The barrier energy needed for heterogeneous nucleation is reduced, and less supercooling is needed.

Homogeneous nucleation occurs spontaneously and randomly, but it requires superheating or supercooling of the medium.

The tank's refrigeration, needed for the supercooling required for the magnetic fields, chilled the air for a yard or two around.

If the cooling rate is slower the supercooling persists to lower temperatures and the transition Tg2 occurs at a lower temperature than Tg1.

When solidifying a liquid, the interface is often unstable, and the velocity of the solid-liquid interface must be small in order to avoid constitutional supercooling.

"Supercooling" is relatively easy to do, but super heating of a solid above its melting point is also possible, but only on a pico-second time scale.

Constitutional supercooling, which occurs during solidification, is due to compositional changes, and results in cooling a liquid below the freezing point ahead of the solid-liquid interface.

Anchor ice sometimes develops on the seabed in shallow Antarctic waters due to the supercooling of water and the deposition of large ice crystals.

The explanation for the supercooling is that ice has a rather intricate crystal structure and water does have some viscosity the inhibits it motions on the molecular scale.

After realizing that in the first experiment the course of Agatha was altered by the supercooling of the areas of the storm, the team decides to apply the same method.

Strong supercooling or intentional addition of crystallization seeds results in relatively large number of nucleation sites; then spherulites are numerous and small and interact with each other upon growth.

The process of supercooling requires that water be pure and free of nucleation sites, which can be achieved by processes like reverse osmosis, but the cooling itself does not require any specialised technique.

Mr. Wasser, the company's president, has sought scientific verification for introducing cryogenics to his manufacturing process for several years, ever since he learned that supercooling had helped strengthen fasteners used on the space shuttle.

There are other reasons such as supercooling and various effects of the surroundings, but we will discount those and assume that the surroundings can be controlled as to remove its effects and that pure water shows very little supercooling.
