Experimental investigation on nucleating agent for low temperature binary eutectic salt hydrate phase change material [PDF]

open access: yesE3S Web of Conferences
The melting enthalpy and melting temperature have a significant impact on the latent heat that results from phase change materials (PCMs) used for thermal energy storage.

Saddle points and dynamics of Lennard-Jones clusters, solids, and supercooled liquids [PDF]

open access: yesThe Journal of Chemical Physics, 2002
The properties of higher-index saddle points have been invoked in recent theories of the dynamics of supercooled liquids. Here we examine in detail a mapping of configurations to saddle points using minimization of |∇E|2, which has been used in previous work to support these theories.

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

open access: yesMetsanduslikud 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 ...

Diapause Induction, Color Changes, and Supercooling Point of Diapause Larvae of Tetrastichus septentrionalis Yang (Hymenoptera: Eulophidae)

open access: yesInsects, 2023
The chalcid wasp Tetrastichus septentrionalis Yang (Hymenoptera: Eulophidae) is one of the dominant pupal parasitoids of Hyphantria cunea (Drury) (Lepidoptera: Erebidae). In this study, the photoperiod’s effect on diapause induction in T. septentrionalis

Fickian crossover and length scales from two point functions in supercooled liquids [PDF]

open access: yesThe Journal of Chemical Physics, 2006
Particle motion of a Lennard-Jones supercooled liquid near the glass transition is studied by molecular dynamics simulations. We analyze the wave vector dependence of relaxation times in the incoherent self-scattering function and show that at least three different regimes can be identified and its scaling properties determined. The transition from one

Freezing Injury Index of Kiwifruit Branches for Main Varieties Under Simulated Low Temperature

open access: yes应用气象学报, 2021
Low temperature freezing injury is the main meteorological disaster affecting the yield and quality of kiwifruit in China. To explore the damage mechanism of low temperature stress on kiwifruit and establish the indices of kiwifruit overwintering ...

The supercooling point depression is the leading cold tolerance strategy for the variegated ladybug, [Hippodamia variegata (Goezel)]

open access: yesFrontiers in Physiology, 2023
The variegated ladybug, Hippodamia variegata is one of the most effective predators of various pests that hibernate as adult beetles. During the overwintering period from April 2021 to March 2022, we examined the supercooling point (SCP), cold tolerance,

Experimental Study of the Freezing Point of γ-AlO/Water Nanofluid

open access: yesAdvances in Mechanical Engineering, 2012
Nanofluids are colloidal suspensions made of nanometer-sized particles dispersed in a conventional fluid. Their unusual thermal properties explain intensive investigations for several thermal and industrial applications.
