Support‐Mediated Reversible Redox Dynamics of Pt and Au on CeO2 at Room Temperature
Small, EarlyView.Atomic‐resolution in situ electron microscopy reveals reversible room‐temperature redox cycling of Pt and Au on CeO2, driven by oxygen‐vacancy‐mediated spillover chemistry. Pt undergoes complete oxidation and reversible wetting–dewetting restructuring with enhanced dispersion, whereas Au shows self‐limiting surface oxidation, highlighting metal ...

Small Methods, EarlyView.Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Advanced Energy Materials, Volume 16, Issue 30, 12 August 2026.Kinetic–energetic projection of time‐resolved photoluminescence reveals that charge‐transfer injection acts as a universal bottleneck in organic solar cells. A physics‐constrained Bayesian framework identifies an emergent effective CT injection rate governing the trade‐off between charge generation and nonradiative energy loss.

Unsteady heat transfer of a monatomic gas between two coaxial circular cylinders
Journal of Applied Mathematics, 2002 We consider a kinetic-theory treatment of the cylindrical unsteady heat transfer. A model kinetic equation of the BGK (Bhatnager-Gross-Krook) type is solved using the method of moments with a two-sided distribution function.

Tracking Dynamic Sulfur Electrochemistry by Operando Techniques in Alkali Metal‐Sulfur Batteries
Advanced Energy Materials, Volume 16, Issue 30, 12 August 2026.Dynamic sulfur electrochemistry in alkali metal‐sulfur batteries is tracked through operando spectroscopy, scattering, imaging, and modelling. This Review connects sulfur reaction pathways, polysulfide transport, electrolyte/interphase evolution, anode chemistry, and quantitative mechanistic analysis across Li‐S, Na‐S, and K‐S batteries, providing ...

Quantum coherence and criticality in irreversible work
Physical Review Research, 2020 The irreversible work during a driving protocol constitutes one of the most widely studied measures in nonequilibrium thermodynamics, as it constitutes a proxy for entropy production.

Thermomass Theory in the Framework of GENERIC
Entropy, 2020 Thermomass theory was developed to deal with the non-Fourier heat conduction phenomena involving the influence of heat inertia. However, its structure, derived from an analogy to fluid mechanics, requires further mathematical verification. In this paper,

An Application of Pontryagin’s Principle to Brownian Particle Engineered Equilibration
Entropy, 2017 We present a stylized model of controlled equilibration of a small system in a fluctuating environment. We derive the optimal control equations steering in finite-time the system between two equilibrium states.

Symmetry-Based Balance Equation for Local Entropy Density in a Dissipative Multibaker Chain System
Entropy, 2013 In this study, the balance equation for local entropy density defined on each partition is obtained by the decomposition of the time-evolution operator for local entropy density, on the level of the master equation, by using symmetric and antisymmetric ...
