Supercooling and cold energy storage characteristics of nano-media in ball-packed porous structures

AIP Advances, 2015
The presented experiments aimed to study the supercooling and cold-energy storage characteristics of nanofluids and water-based nano-media in ball-packed porous structures (BPS). Titanium dioxide nanoparticles (TiO2 NPs) measuring 20nm and 80nm were used

Storage Capacity in Dependency of Supercooling and Cycle Stability of Different PCM Emulsions

Applied Sciences, 2021
Phase-change materials (PCM) play off their advantages over conventional heat storage media when used within narrow temperature ranges. Many cooling and temperature buffering applications, such as cold storage and battery cooling, are operated within ...

Supercooled confinement

Journal of High Energy Physics
A bstract We study general properties of confinement phase transitions in the early universe. An observable gravitational wave signal from such transitions requires significant supercooling.

Starch in Overwintering Supercooling and Non-supercooling Woody Plants and Its Possible Relationship to Cold Hardiness

Journal of the American Society for Horticultural Science
Woody plants have evolved a suite of winter survival traits. Supercooling species are constrained to temperatures above ∼−40 °C, whereas non-supercooling species can survive colder temperatures.

Supercooling capacity and cold hardiness of the eggs of the grasshopper Chorthippus fallax (Orthoptera: Acrididae)

European Journal of Entomology, 2004
Cold tolerance of the eggs of the grasshopper, Chorthippus fallax (Zubovsky), was examined in the laboratory. Egg supercooling points varied from -6°C to -32.4°C and could be divided into two groups. The supercooling points of the higher SCP group ranged

Climatic Variation of Supercooling Point in the Linden Bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

Insects, 2018
Cold tolerance is often one of the key components of insect fitness, but the association between climatic conditions and supercooling capacity is poorly understood.

Experimental study of the effects of ultrasound on the supercooling of water

Zhileng xuebao, 2003
The research on the supercooling of water is important in the fields of ice storage and cryobiology.The pressure fluctuation brought by the ultrasound will influence the supercooling and nucleation process of water.In this study experiments are carried ...

Seasonal cold adaptation dynamics of some carabid beetle species: Carabus granulatus, Pterostichus oblongopunctatus and Platynus assimilis

Metsanduslikud Uurimused, 2012
Cold-hardiness can be measured by supercooling points – the temperature at which spontaneous freezing occurs. Seasonal changes in supercooling point were assessed in field-collected predacious carabid beetle species: Carabus granulatus L., Pterostichus ...

Cold tolerance and trehalose accumulation in overwintering larvae of the codling moth, Cydia pomonella (Lepidoptera: Tortricidae)

European Journal of Entomology, 2007
Seasonal variations in the supercooling point, survival at low temperatures and sugar content were studied in field-collected codling moth larvae. The supercooling point of field-collected larvae decreased significantly from a mean value of -13.4°C in ...
