Mechanism to Diminish the Supercooling of the Tin Freezing Point by using Graphite Powder

International Journal of Thermophysics, 2008
The formation of crystallization centers from extremely pure molten tin is normally associated with deep supercooling. This deep supercooling is inconvenient for the operation of tin freezing-point cells, especially for sealed tin fixed-point cells without a holder to facilitate removal from the furnace.

Peculiar Thermodynamics of the Second Critical Point in Supercooled Water

The Journal of Physical Chemistry B, 2011
On the basis of the principle of critical-point universality, we examine the peculiar thermodynamics of the liquid-liquid critical point in supercooled water. We show that the liquid-liquid criticality in water represents a special kind of critical behavior in fluids, intermediate between two limiting cases: the lattice gas, commonly used to model ...

The influence of the compounds dissociation in melting point on melt supercooling

Journal of Crystal Growth, 2008
Thermodynamic properties of binary alkali borate systems Me2O–B2O3 have been studied in the framework of sub-regular solution theory approximation. The oscillation method of phase analysis was used to obtain precise data for solid–liquid equilibria.

Supercooling Points of Several Species of Lepidoptera Found on Soybeans

Environmental Entomology, 1972
Supercooling is the ability of an insect to withstand low temperatures before freezing, and in insects it is limited to 30–35°C (Salt 1961). Supercooling points were determined for pupae of 10 species of Lepidoptera found on soybeans. Ability of an insect to supercool is an indication of cold tolerance, but the mean supercooling point of any species ...

Surface Tension of Supercooled Water: No Inflection Point down to −25 °C

The Journal of Physical Chemistry Letters, 2014
A dramatic increase in the surface tension of water with decreasing temperature in the supercooled liquid region has appeared as one of the many anomalies of water. This claimed anomaly characterized by the second inflection point at about +1.5 °C was observed in older surface tension data and was partially supported by some molecular simulations and ...

Supercooling points of insects and mites on the Antarctic Peninsula

Ecological Entomology, 1982
Abstract. 1. Mean supercooling points of eleven species of arthropods (three Collembola, seven Acari and one Diptera) ranged from ‐6.2 to ‐9.4°C (high group), and from ‐17.7 to ‐31.0°C (low group). The majority of individuals in the high group had food in their gut systems.

Freezing-tolerant insects with low supercooling points

Comparative Biochemistry and Physiology Part A: Physiology, 1982
1. 1. Pytho deplanatus [Coleoptera: Pythidae (Salpingidae)] is an alpine species that overwinters as a larva under the bark of fallen spruce in the Rocky Mountains. It belongs to a small group of insects which not only is tolerant of freezing but also develops the capacity to supercool to low sub-zero temperatures (−54°C), indeed in this case the ...

A thermoelectric microscope stage for the measurement of the supercooling points of microscopic organisms

Journal of Microscopy, 1984
SUMMARYThe design and construction of a thermoelectric cooling stage and its use for the determination of the supercooling points of microscopic organisms is described. Stage cooling is produced by a Peltier unit with a refrigerated circulator as a heat sink.

Supercooling and superheating of the AB transition in superfluid3He near the polycritical point

Journal of Low Temperature Physics, 1974
Experimental measurements of the cooling (A→B) and warming (B→A) transitions between 3 He-A and 3 He-B are presented for fields of 378 and 5 G. The relationship of these measurements to the existence in zero field of a polycritical point on the line of second-order transitions is then ...
