The time evolution governed by the Boltzmann kinetic equation is compatible with mechanics and thermodynamics. The former compatibility is mathematically expressed in the Hamiltonian and Godunov structures, the latter in the structure of gradient dynamics guaranteeing the growth of entropy and consequently the approach to equilibrium. We carry all three structures to the Grad reformulation of the Boltzmann equation (to the Grad hierarchy). First, we recognize the structures in the infinite Grad… 
Lifts of Symmetric Tensors: Fluids, Plasma, and Grad Hierarchy
A purely geometric pathway is proposed, which establishes a link from particle motion to evolution of the field variables, and is an alternative to the usual Hamiltonian approach to mechanics based on Poisson brackets.
Multiscale thermodynamics of charged mixtures
A multiscale theory of interacting continuum mechanics and thermodynamics of mixtures of fluids, electrodynamics, polarization, and magnetization is proposed. The mechanical (reversible) part of the
Comparison of the Symmetric Hyperbolic Thermodynamically Compatible framework with Hamiltonian mechanics of binary mixtures
How to properly describe continuum thermodynamics of binary mixtures where each constituent has its own momentum? The Symmetric Hyperbolic Thermodynamically Consistent (SHTC) framework and
GENERIC guide to the multiscale dynamics and thermodynamics

Thermodynamic Explanation of Landau Damping by Reduction to Hydrodynamics
Density and kinetic energy density, which are integrals of the distribution function, approach spatially homogeneous states strongly, which is accompanied by growth of the hydrodynamic entropy, andLandau damping is the tendency of solutions to the Vlasov equation towards spatiallyhomogeneous distribution functions.
Gradient and GENERIC time evolution towards reduced dynamics
It is shown that the flux-entropy driving the flux time evolution becomes, if evaluated at the fixed point, the flux fundamental thermodynamic relation in the reduced dynamical theory, which is a potential related to the entropy production.
Conservation-Dissipation Formalism for soft matter physics: I. Augmentation to Doi's variational approach
It is proved that by choosing the proper variational function and variables, the variational approach proposed by Doi in soft matter physics is equivalent to the Conservation-Dissipation Formalism.
The Markov process admits a consistent steady-state thermodynamic formalism
The search for a unified formulation for describing various non-equilibrium processes is a central task of modern non-equilibrium thermodynamics. In this paper, a novel steady-state thermodynamic


Moment closure hierarchies for kinetic theories
This paper presents a systematicnonperturbative derivation of a hierarchy of closed systems of moment equations corresponding to any classical kinetic theory. The first member of the hierarchy is the
Galilean invariance and entropy principle for systems of balance laws
The Galilean invariance of a generic system of balance laws dictates a specific dependence of the densities and fluxes on velocity. Thus these quantities decompose in a unique manner into convective

The Entropy Principle from Continuum Mechanics to Hyperbolic Systems of Balance Laws: The Modern Theory of Extended Thermodynamics
The different roles of the entropy principle in modern thermodynamics are discussed and a particular attention is given on the local and global well-posedness of the relative Cauchy problem for smooth solutions.

All dynamical theories discussed in the paper are fully nonlinear and all are proven to be compatible among themselves, with equilibrium thermodynamics, and with mechanics.
Extensions of Classical Hydrodynamics
An abstract dynamical system is formulated from three features extracted from classical hydrodynamics. One its particular realization is then the classical hydrodynamics, other possible realizations
Contact Geometry of Mesoscopic Thermodynamics and Dynamics
The time evolution during which macroscopic systems reach thermodynamic equilibrium states proceeds as a continuous sequence of contact structure preserving transformations maximizing the entropy, providing a unified setting for the classical equilibrium and nonequilibrium thermodynamics, kinetic theory, and statistical mechanics.

In this paper we propose a novel approach to construct macroscopic balance equations and constitutive equations describing various irreversible phenomena. It is based on the general principles of
Solutions of the moment hierarchy in the kinetic theory of Maxwell models
In the Maxwell interaction model the collision rate is independent of the relative velocity of the colliding pair and, as a consequence, the collisional moments are bilinear combinations of velocity
