Relativistic Heat Conduction in the Large-Flux Regime

Entropy
We propose a general procedure for evaluating, directly from microphysics, the constitutive relations of heat-conducting fluids in regimes of large fluxes of heat.

Heat equation for porous nanostructures filled by a fluid flow

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In a previous paper, in the framework of extended irreversible thermodynamics with internal variables, a model for nanostructures with thin porous channels filled by a fluid flow was developed.

The effects of nonlocality on the evolution of higher order fluxes in non-equilibrium thermodynamics

, 2004
The role of gradient dependent constitutive spaces is investigated on the example of Extended Thermodynamics of rigid heat conductors. Different levels of nonlocality are developed and the different versions of extended thermodynamics are classified. The

Stabilizing Cationic Palladium Single‐Atom Sites on Heteroatom‐Doped Carbon for Selective Hydrogen Peroxide Electrosynthesis

Advanced Functional Materials, EarlyView.
In this research, it is demonstrated that dual nitrogen and sulfur doping in hollow carbon spheres creates a tunable coordination environment that stabilizes cationic Pd single atoms as robust organometallic complexes, enabling high selectivity and stability for electrochemical hydrogen peroxide production under harsh acidic and peroxide‐rich ...

Boundary conditions and extended constitutive relations for spin-flow coupling in dipolar fluids

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Boundary conditions are formulated, within the framework of irreversible thermodynamics, for the velocity, the angular velocity and the dipole vector parallel to the average electric dipole moment of a streaming dipolar fluid.

Dual‐Phased Molybdenum Carbides Confined in MOF‐Derived Carbon Nanoframes Enhance Capacitive Desalination

Advanced Functional Materials, EarlyView.
Dual‐phase MoC/Mo2C/CoNC nanoframes are synthesized via a MOF‐on‐MOF strategy, demonstrating a large salt adsorption capacity, a low energy consumption, and an excellent cycling stability. In situ/ex situ characterizations and DFT calculations reveal that the MoC/Mo2C dual phase transition facilitates Na+ adsorption/desorption, while interface‐induced ...

Deciphering the Interplay Between Wetting and Chemo‐Mechanical Fracture in Lithium‐Ion Battery Cathode Materials

Advanced Functional Materials, EarlyView.
The fundamental intricate couplings between electrolyte wetting and fracture evolution are investigated in large single‐crystal V2O5 samples using both experimental techniques and simulations. Both approaches reveal consistent fracture patterns and lithium distribution concentration maps influenced by the wetting mechanism.

Revisiting Gassmann-type relationships within Biot poroelastic theory [PDF]

Solid Earth
Gassmann's equations have long served as a cornerstone of geophysics and rock physics, widely regarded as exact within their domain of applicability. However, recent studies have questioned their validity, arguing that Gassmann's derivation involves a ...
