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

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.

Partial liquid metal dealloying to synthesize nickel-containing porous and composite ferrous and high-entropy alloys

open access: yesCommunications Materials, 2023
Liquid metal dealloying is a promising technique to produce bicontinuous porous metals with high specific surface areas. This processing technique relies on the selective dissolution of a component from a precursor alloy into a metal bath while the ...

Dynamical arrest of ultracold lattice fermions [PDF]

open access: yes, 2013
We theoretically investigate the thermodynamics of an interacting inhomogeneous two-component Fermi gas in an optical lattice. Motivated by a recent experiment by L.

Statistical Thermodynamics of Clustered Populations [PDF]

open access: yes, 2014
We present a thermodynamic theory for a generic population of $M$ individuals distributed into $N$ groups (clusters). We construct the ensemble of all distributions with fixed $M$ and $N$, introduce a selection functional that embodies the physics that ...

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.

THERMODYNAMICS TEACHING IN INORGANIC CHEMISTRY: PROBLEMS AND SOLUTIONS AT LOCAL NORMAL UNIVERSITIES [PDF]

open access: yesQuímica Nova
Thermodynamics is a crucial component of the inorganic chemistry curriculum in local normal universities. Currently, the teaching of this subject faces several practical issues, including ambiguous content positioning, poor connection between high school

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

Disturbance triggers non-linear microbe–environment feedbacks [PDF]

open access: yesBiogeosciences, 2021
Conceptual frameworks linking microbial community membership, properties, and processes with the environment and emergent function have been proposed but remain untested.
