An alternative study about the geometry and the first law of thermodynamics for AdS Lovelock gravity, using the definition of conserved charges [PDF]

, 2022
In this work it is introduced an extension of the study of the first law of thermodynamics of black holes based on the geometry of the extended phase space for AdS Lovelock gravities which includes changes of scales.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Stochastic and Macroscopic Thermodynamics of Strongly Coupled Systems

Physical Review X, 2017
We develop a thermodynamic framework that describes a classical system of interest S that is strongly coupled to its thermal environment E. Within this framework, seven key thermodynamic quantities—internal energy, entropy, volume, enthalpy, Gibbs free ...

The Pressure Dependence of the Stability of the G-quadruplex Formed by d(TGGGGT)

Life, 2022
The G-quadruplex (GQ), a tetrahelix formed by guanine-rich nucleic acid sequences, is a potential drug target for several diseases. Monomolecular GQs are stabilized by guanine tetrads and non-guanine regions that form loops.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Internally Consistent Ion Volumes and Their Application in Volume-Based Thermodynamics

, 2016
“Volume-based thermodynamics” (VBT) relates the thermodynamics of condensed-phase materials to their formula unit (or molecular) volumes, Vm. In order to secure the most accurate representation of these data, the volumes used are to be derived (in order ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Incremental least action principle in the framework of thermodynamics of irreversible processes

Physical Review Research, 2020
In this paper, an incremental least action principle is proposed using the framework of the thermodynamics of irreversible processes. First, we establish that an extensive thermodynamic potential defined over an infinitesimal volume satisfies a ...
