First-Principles Atomistic Thermodynamics and Configurational Entropy

open access: yesFrontiers in Chemistry, 2020
In most applications, functional materials operate at finite temperatures and are in contact with a reservoir of atoms or molecules (gas, liquid, or solid).

A quantitative study on the thermomechanical coupling effect of elasticity and plasticity of polymethyl methacrylate

open access: yesPolymer Testing, 2023
Quantitative study on the elastic and plastic thermomechanical coupling effect of solid materials has important theoretical significance for monitoring the deformation state and stability evaluation of engineering components. In this study, the sample is

On Thermodynamic and Kinetic Mechanisms for Stabilizing Surface Solid Solutions

open access: yesACS Applied Materials & Interfaces, 2019
Many processes for energy storage rely on transformations between phases with strong separation tendencies. In these systems, performance limitations can arise from undesirable chemical and mechanical factors associated with the phase separation behavior. Solid solutions represent a desirable alternative, provided the conditions for their formation are

Hot and Heavy Matters in the Foundations of Statistical Mechanics [PDF]

open access: yes, 2010
Are the generalizations of classical equilibrium thermodynamics true of self-gravitating systems? This question has not been addressed from a foundational perspective, but here I tackle it through a study of the "paradoxes" commonly said to afflict such ...

Mechanical and thermodynamic properties of surfactant aggregates at the solid–liquid interface

open access: yesJournal of Colloid and Interface Science, 2004
Surfactants are widely used to stabilize colloidal systems in a variety of industrial applications through the formation of self-assembled aggregates at the solid-liquid interface. Previous studies have reported that the control of surfactant-mediated slurry stability can be achieved through the manipulation of surfactant chain length and concentration.

Dependence of Heat Transport in Solids on Length-Scale, Pressure, and Temperature: Implications for Mechanisms and Thermodynamics [PDF]

open access: yesMaterials, 2021
Accurate laser-flash measurements of thermal diffusivity (D) of diverse bulk solids at moderate temperature (T), with thickness L of ~0.03 to 10 mm, reveal that D(T) = D∞(T)[1 − exp(−bL)]. When L is several mm, D∞(T) = FT−G + HT, where F is constant, G is ~1 or 0, and H (for insulators) is ~0.001. The attenuation parameter b = 6.19D∞−0.477 at 298 K for

Mechanical Proof of the Second Law of Thermodynamics Based on Volume Entropy [PDF]

open access: yes, 2007
In a previous work (M. Campisi. Stud. Hist. Phil. M. P. 36 (2005) 275-290) we have addressed the mechanical foundations of equilibrium thermodynamics on the basis of the Generalized Helmholtz Theorem.

Second law of thermodynamics and the failure of rock materials [PDF]

open access: yes, 2001
The relation of nonequilibrium thermodynamics to some failure and fracture theories of rock mechanics is investigated. The basic concepts are given to connect failure to the properties of material equations describing the elastic properties.

Heat-exchange statistics in driven open quantum systems

open access: yesNew Journal of Physics, 2014
As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects.

Incommensurate Crystallization of Neutron Matter in Neutron Stars

open access: yesEast European Journal of Physics, 2020
The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...
