Thermodynamic Weirdness, 2022
The concept of entropy constitutes, together with energy, a cornerstone of contemporary physics and related areas. It was originally introduced by Clausius in 1865 along abstract lines focusing on thermodynamical irreversibility of macroscopic physical ...

High-entropy nanoparticles: Synthesis-structure-property relationships and data-driven discovery
Science, 2022High-entropy nanoparticles have become a rapidly growing area of research in recent years. Because of their multielemental compositions and unique high-entropy mixing states (i.e., solid-solution) that can lead to tunable activity and enhanced stability,

On preimage entropy, folding entropy and stable entropy
Ergodic Theory and Dynamical Systems, 2020For non-invertible dynamical systems, we investigate how ‘non-invertible’ a system is and how the ‘non-invertibility’ contributes to the entropy from different viewpoints. For a continuous map on a compact metric space, we propose a notion of pointwise metric preimage entropy for invariant measures.

High Configuration Entropy Activated Lattice Oxygen for O2 Formation on Perovskite Electrocatalyst
Advanced Functional Materials, 2022The single‐phase oxides with elemental complexity and compositional diversity, usually named high entropy oxides, feature homogeneously dispersed multi‐metallic elements in equiatomic concentration.

Nonequilibrium entropy and entropy distributions
Physical Review B, 1990Glasses have nonzero zero-temperature entropies. Because they are out of equilibrium, the ``thermodynamic'' entropy, determined by heat flow, is not equal to the ``statistical'' entropy, which measures volumes in phase space. We discuss the relationship between the two kinds of entropy in nonequilibrium systems and show that the thermodynamic entropies

Entropy and entropy of mixing [PDF]
Materialwissenschaft und Werkstofftechnik, 2014 Entropy as a function of temperature at constant volume, S(T), can be determined by integrating the molar specific entropy capacity CV/T (CV: molar specific heat capacity at constant volume). As a second approach, S(T) at constant volume can be determined by differentiating the free energy with respect to the temperature, T. Recently, it has been shown
