A metastable liquid may exist under supercooling, sustaining the liquid below the melting point such as supercooled water and silicon. It may also exist as a transient state in solid-solid transitions, as demonstrated in recent studies of colloidal particles and glass-forming metallic systems. One important question is whether a crystalline solid may directly melt into a sustainable metastable ...

Water has a complex phase diagram with more than 16 crystalline phases, two glass phases and liquid which displays many unique behaviors, especially in the region of -45 °C (Mishima and Stanley 1998, Stokely et al. 2010). It can remain a liquid even under conditions where a more stable phase exists, and in those conditions is said to be supercooled. Supercooled water can be prompted to turn int...

The quark-hadron phase transition in the early universe can produce inho-mogeneities in the distribution of nucleons, which in turn affect the primordial nucleosynthesis. In all the investigations of this problem it has been assumed that the degree of supercooling of the quark-gluon plasma after the phase transition is large enough to produce a significant rate of nucleation of hadrons. Using t...

We report the limits of superheating of water and supercooling of vapor from Monte Carlo simulations using microscopic models with configurational enthalpy as the order parameter. The superheating limit is well reproduced. The vapor is predicted to undergo spinodal decomposition at a temperature of Tspvap=46±10 °C (0 °C≪Tspvap≪100 °C) under 1 atm. The water-water network begins to form at the s...

Zero-field-cooling and field-cooling FC measurements were performed on ferrofluids of cobalt magnetic nanoparticles MNPs in various organic solvent. Two peaks, one broad peak corresponding to the blocking transition TB , and one sharp peak corresponding to the melting of the solvent TM , were observed. Furthermore, for a given MNP size, when the blocking and melting transitions were superposed ...

Subzero temperatures may adversely affect animals by their direct lethal effects and by the damage caused by ice formation (Ramløv, 2000). Animals deal with the latter by three basic strategies. Freeze avoiding animals prevent ice formation in their bodies and supercool, keeping their body fluids liquid at temperatures below their melting point, but die if freezing occurs. In contrast, freezing...

According to the ASTM D97, pour point is temperature below which petroleum products cease flow. To evaluate relevance of measurements for synthetic lubricating oils, we investigated crystallization, melting and low-temperature flow behavior one mineral five oils. The classification three groups emerged from this process. formation paraffin crystals in oils (I) crystallization causes shear-thinn...
