Covariant thermodynamics of an object with finite volume [PDF]
Physics Letters A, 2006 A covariant way to define the relativistic entropy of a finite object has been proposed. The energy-momentum of an object with finite volume is not a covariant physical entity because of the relativity of simultaneity. A way to correctly handle this situation is introduced and applied to the calculation of entropy.

Discretization of continuum physics – a comparison of numerical methods from a physical point of view; pp. 145–154 [PDF]
Proceedings of the Estonian Academy of Sciences, 2008 For numerical calculations in continuum physics partial differential equations and the space-time are discretized. This can be done in different ways. Common approaches are finite difference methods and finite element methods, more rarely finite volume ...

A New Entropy Function to Analyze Isentropic Processes of Ideal Gases with Variable Specific Heats
Entropy, 2022 A new entropy function s+ is defined in terms of the existing entropy function s° and temperature as s+ = s° − R lnT to facilitate the analysis of isentropic processes of ideal gases with variable specific heats. The function s+ also makes it possible to

Defining the pressures of a fluid in a nanoporous, heterogeneous medium
Frontiers in Physics, 2022 We describe the thermodynamic state of a single-phase fluid confined to a porous medium with Hill’s thermodynamics of small systems, also known as nanothermodynamics.

Improved thermodynamics of SU(2) gauge theory
European Physical Journal C: Particles and Fields, 2017 In this work we present the results of our investigation of the thermodynamics of SU(2) gauge theory. We employ a Symanzik improved action to reduce strongly the discretisations effects, and we use the scaling relations to take into account the finite ...

Revisit on holographic complexity in two-dimensional gravity
Journal of High Energy Physics, 2020 We revisit the late-time growth rate of various holographic complexity conjectures for neutral and charged AdS black holes with single or multiple horizons in two dimensional (2D) gravity like Jackiw-Teitelboim (JT) gravity and JT-like gravity.

Research Progress of Alloy Anodes for Lithium ion Batteries
Taiyuan Ligong Daxue xuebao, 2021 Alloy anodes are potential anode materials for lithium ion batteries with high specific capacity and high safety. The different lithium (de)intercalation mechanisms of alloy anodes significantly affect the key issues such as dendrite growth, Li transport,

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
