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.

Solution thermodynamics for “reactive” components

open access: yesFluid Phase Equilibria, 1981
Abstract A unifying mathematical analysis is presented for the thermodynamic properties of a system of components which undergo chemical transformations (reaction, association, solvation, ionization) or are modelled as such (“chemical theory”, “solutions of groups”) in terms of the properties of the resultant species. Several examples are given.

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

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.

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.

Thermodynamics of the low density excluded volume hadron gas

open access: yes, 2015
We consider thermodynamics of the excluded volume particles at finite temperature and chemical potential, in the low density approximation. We assume Boltzmann statistics and study the influence of the excluded volume on an ideal gas thermodynamics at ...

Analytical thermodynamics of a strongly attractive three-component Fermi gas in one dimension

open access: yes, 2010
Ultracold three-component atomic Fermi gases in one dimension are expected to exhibit rich physics due to the presence of trions and different pairing states.

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 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
