Latent heat of the largeNfinite temperature phase transition

Latent heat in the chiral phase transition

A many-particle system in general possesses two or more different forms of existence called phases. Conversions between these phases are called phase transitions. There are mainly two kinds of phase transitions. One is the first-order phase transition, the other is the secondorder one. In the first-order phase transition, as in the conversion from vapor to liquid, the entropy of the system chan...

Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals

Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...

Is the Freeze Drying Method Effect on the Phase Transition Temperature ofβ/β́́ Lithium Zirconium Phosphate?

Spherical granules of the superionic conductor β/β́ LiZr2(PO4)3 in the range of sub 100 nm sizewere synthesizedvia freeze drying methodand fully reviewed in all aspects. Samples were characterized by the X-ray diffractometry (XRD), the Thermal analysis (TG, DSC), theFourier Transform Infra-Red Spectroscopy (FTIR) and the Scanning Electron Microscopy (SEM).Their structuredepends largely on the me...

Latent heat of the first-order magnetic transition of MnFeSi0.33P0.66

Anomalous latent heat in nonequilibrium phase transitions.

We study first-order phase transitions in a two-temperature system, where due to the time-scale separation all the basic thermodynamical quantities (free energy, entropy, etc.) are well defined. The sign of the latent heat is found to be counterintuitive: it is positive when going from the phase where the temperatures and the entropy are higher to the one where these quantities are lower. The e...
