Supercooling points of insects and mites on the Antarctic Peninsula
Ecological Entomology, 1982Abstract. 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, 19821. 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 ...

Surface Tension of Supercooled Water: No Inflection Point down to −25 °C
The Journal of Physical Chemistry Letters, 2014A 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 were determined for eggs, 3rd instars, pupae, newly emerged unfed adults and 3-d-old engorged laboratory reared adults of Haematobia irritans (L.) and Stomoxys calcitrans (L.). Wild nondiapausing and diapausing pupae of H. irritans also were tested. Mean supercooling points ranged from -28.0 degrees C for H.

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, 1974Experimental 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 ...

Detection of supercooled drizzle by a vertically pointing radar
2002The objective of this study is to detect zones of supercooled drizzle using data from a vertically pointing radar (VPR). This radar was used in the AIRS (Alliance Icing Research Study) experiment held at Mirabel Airport from November 1999 to February 2000.

Supercooling point is an individually fixed metric of cold tolerance in Pyrrhocoris apterus
Journal of Thermal Biology, 2018Measuring the supercooling point (SCP) is a standard procedure to describe the cold tolerance of freeze-avoiding arthropods. The SCP of an individual animal is a stochastic event that will occur with increasing probability as the temperature is lowered below the freezing point of that animal.

Energy landscape, minimum points and non-Arrhenius behavior of supercooled liquids
AIP Conference Proceedings, 1998A theoretical explanation of the non-Arrhenius behavior observed in supercooled liquids at sufficiently low temperatures is given using length scales, transition rates and time scales in the 3N-dimensional configuration space. The relaxation time and the viscosity, respectively, can be expressed as nonlinear functions of the reduced inverse temperature

Physical Review E, 2014
In this paper we study the four-point correlation function χ(4) of collective density fluctuations in a nonequilibrium liquid. The equilibration is controlled by a modified stretched exponential behavior (exp[-(t(w)/τ)(β)]) having the relaxation time τ dependent on the aging time t(w).
