Fourier’s Law in a Generalized Piston Model
Entropy, 2017 A simplified, but non trivial, mechanical model—gas of N particles of mass m in a box partitioned by n mobile adiabatic walls of mass M—interacting with two thermal baths at different temperatures, is discussed in the framework of kinetic theory ...

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN
Advanced Functional Materials, EarlyView.Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

Conformal Symmetry and Cosmological Entropy Production
Entropy, 2002 : Introducing an effective refraction index of an isotropic cosmic medium, we investigate the cosmological fluid dynamics which is consistent with a conformal, timelike symmetry of a corresponding "optical" metric.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Wave propagation in discrete kinetic theory
Le Matematiche, 1991 The paper is a review of shock wave propagation problems for inert and chemically reacting gases in the framework of discrete velocity models (Discrete Boltzmann Equation, DBE). The paper is divided in two parts.

Advanced Functional Materials, EarlyView.A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Advanced Functional Materials, EarlyView.A gradient M/MOx (M = Sn, Cu, Cd) synergistic interphase was constructed on Al via a one‐step displacement reaction. This interphase leverages high aluminophilicity and ion‐buffering capability to accelerate desolvation, enhance Al3+ transport, and suppress side reactions, enabling ultrastable symmetric cell operation at 0.05 mA cm−2 for 1800 h with an
