Interpretation of Adsorption Thermodynamics and Kinetics

open access: yesOpen Journal of Physical Chemistry, 2020
A complete study of adsorption processes will be less complete if the structure and dynamics of its different elements and how they interact is not well captured.

Black hole chemistry: thermodynamics with Lambda [PDF]

open access: yes, 2016
We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic variable in its own right.

Analysis of low‐temperature pumped thermal energy storage systems based on a transcritical CO2 charging process

open access: yesEnergy Science & Engineering, 2023
Pumped thermal energy storage (PTES) is a technology for intermediate storage of electrical energy in the form of thermal energy. In this work, PTES systems based on a transcritical CO2 charging process are investigated.

Quantum Thermodynamics: A Nonequilibrium Green's Functions Approach [PDF]

open access: yes, 2015
We establish the foundations of a nonequilibrium theory of quantum thermodynamics for noninteracting open quantum systems strongly coupled to their reservoirs within the framework of the nonequilibrium Green functions (NEGF). The energy of the system and

Typical Periods for Two-Stage Synthesis by Time-Series Aggregation with Bounded Error in Objective Function

open access: yesFrontiers in Energy Research, 2018
Two-stage synthesis problems simultaneously consider here-and-now decisions (e.g., optimal investment) and wait-and-see decisions (e.g., optimal operation). The optimal synthesis of energy systems reveals such a two-stage character.

Demonstration of the stabilization of solar salt at 620 C with a semi-closed configuration in a 100 kg-scale

open access: yesHeliyon, 2023
Among the variety of energy storage techniques thermal energy storage (TES), based on molten salts, is already in use for the storage of heat in a gigawatt hour scale.

Quantum Thermodynamics

open access: yes, 2013
Quantum thermodynamics addresses the emergence of thermodynamical laws from quantum mechanics. The link is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems.

Thermodynamically consistent gradient elasticity with an internal variable

open access: yes, 2020
The role of thermodynamics in continuum mechanics and the derivation of the proper constitutive relations is a discussed subject of Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical ...

A Resource Theory for Work and Heat [PDF]

open access: yes, 2017
Several recent results on thermodynamics have been obtained using the tools of quantum information theory and resource theories. So far, the resource theories utilised to describe thermodynamics have assumed the existence of an infinite thermal reservoir,

A Schroedinger link between non-equilibrium thermodynamics and Fisher information

open access: yes, 2002
It is known that equilibrium thermodynamics can be deduced from a constrained Fisher information extemizing process. We show here that, more generally, both non-equilibrium and equilibrium thermodynamics can be obtained from such a Fisher treatment ...
