Modelling and simulation of brinicle formation
Royal Society Open Science, 2023 Below the Arctic sea ice, under the right conditions, a flux of icy brine flows down into the sea. The icy brine has a much lower fusion point and is denser than normal seawater.

Convection of snow: when and why does it happen?
Frontiers in Earth Science, 2023 Convection of water vapor in snowpacks is supposed to have a major impact on snow density and microstructure profiles with strong implications for the thermal regime and snow stability.

Quasicrystalline phase-change memory [PDF]
Scientific Reports, 2020 AbstractPhase-change memory utilizing amorphous-to-crystalline phase-change processes for reset-to-set operation as a nonvolatile memory has been recently commercialized as a storage class memory. Unfortunately, designing new phase-change materials (PCMs) with low phase-change energy and sufficient thermal stability is difficult because phase-change ...

Phase-change chalcogenide glass metamaterial [PDF]
, 2009 Combining metamaterials with functional media brings a new dimension to their performance. Here we demonstrate substantial resonance frequency tuning in a photonic metamaterial hybridized with an electrically/optically switchable chalcogenide glass.

Theoretical Study on the Ice Melting with Transient Double Effects of Temperature and Concentration
Journal of Thermal Science and Technology, 2013 The melting of the ice plate with the transient double effects of the temperature and concentration was studied theoretically. In the present study, our main attention was paid to the early stage of melting, when the abrupt changes of the temperature and

Elevated LNG Vapour Dispersion—Effects of Topography, Obstruction and Phase Change
Eng, 2021 The dispersion of vapour of liquefied natural gas (LNG) is generally assumed to be from a liquid spill on the ground in hazard and risk analysis. However, this cold vapour could be discharged at height through cold venting.

Effect of Gas Channel on Water Formation in Polymer Electrolyte Fuel Cell
Journal of Thermal Science and Technology, 2009 Water management is important for the development of polymer electrolyte fuel cells (PEFCs) having high performance and reliability. Experimental and numerical studies were carried out on PEFCs with serpentine channels. Two channel widths, 2 mm and 8 mm,

Strangeness at the threshold of phase change [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2008 We explore entropy and strangeness as signature of QGP for top AGS energy and the energy scan at SPS. We find that the hadronization dynamics changes between 20 and 30 $A$ GeV projectile energy. The high energy results are consistent with QGP.
