Does the second critical-point of water really exist in nature?

open access: yesCondensed Matter Physics, 2022
In the past decade, a literary phrase “No man's land” has been flooded in the scientific papers. The expression is used to describe a meta-stable region in the phase-diagram that cannot be accessed by experiments.

Conditions for and Characteristics of the Dispersion of Gel Fuel Droplets during Ignition

open access: yesApplied Sciences, 2023
We formulated and experimentally proved a hypothesis on the causes of dispersion (puffing and microexplosion) of binary fuel droplets, including those in the composition of gel fuels. This hypothesis is based on the concepts of wetting thermodynamics and

Necessity of Dark Energy from Thermodynamic Arguments

open access: yesAdvances in High Energy Physics, 2014
Considering the cosmic fluid as a quasi-static thermodynamic system, the status of the generalized second law of thermodynamics is investigated and the valid range of the equation of state parameter is derived for a few important cosmological models. Our

Symplectic Foliation Structures of Non-Equilibrium Thermodynamics as Dissipation Model: Application to Metriplectic Nonlinear Lindblad Quantum Master Equation

open access: yesEntropy, 2022
The idea of a canonical ensemble from Gibbs has been extended by Jean-Marie Souriau for a symplectic manifold where a Lie group has a Hamiltonian action.

Thermodynamical aspects of the introduction processes

open access: yesІнтродукція Рослин, 2019
The theoretical component of the introductory process from the standpoint of the laws of thermodynamics is determined. At the ecosystem level, vegetation groups with specific environmental conditions characteristic of each species have been analyzed. The

Nanothermodynamic Description and Molecular Simulation of a Single-Phase Fluid in a Slit Pore

open access: yesNanomaterials, 2021
We have described for the first time the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill’s thermodynamics of small systems. Hill’s theory has been named nanothermodynamics.

Application of Continuous Thermodynamics to Natural-Gas Mixtures Application de la thermodynamique continue aux mélanges de gaz naturel

open access: yesOil & Gas Science and Technology, 2006
This work reviews recent progress in the application of continuous thermodynamics towards calculation of phase equilibria in natural-gas mixtures. In such mixtures, there may be too many components to identify each component individually.

Microstructure Analysis of Equiatomic Multi-Component NI20TI20TA20CO20CU20 Alloy [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
An equiatomic multi-component alloy Ni20Ti20Ta20Co20Cu20 (at. %) was obtained using vacuum arc melting. In order to characterize such an alloy, microstructure analysis has been performed using Scanning and Transmission Electron Microscopy, Electron ...

Phenomenological Fluids from Interacting Tachyonic Scalar Fields [PDF]

open access: yes, 2013
In this paper we are interested to consider mathematical ways to obtain different phenomenological fluids from two-component Tachyonic scalar fields. We consider interaction between components and investigate problem numerically.

Chemical Association via Exact Thermodynamic Formulations [PDF]

open access: yes, 1998
It can be fruitful to view two-component physical systems of attractive monomers, A and B, ``chemically'' in terms of a reaction A + B C, where C = AB is an associated pair or complex.
