Matter creation, adiabaticity and phantom behavior

open access: yesEuropean Physical Journal C: Particles and Fields
We present a novel cosmological framework that unifies matter creation dynamics with thermodynamic principles. Starting with a single-component fluid characterized by a constant equation of state parameter, $$\omega $$ ω , we introduce a generalized ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

The Origins of Time-asymmetry in Thermodynamics: The Minus First Law [PDF]

open access: yes, 2001
This paper investigates what the source of time-asymmetry is in thermodynamics, and comments on the question whether a time-symmetric formulation of the Second Law is ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

A History of Thermodynamics: The Missing Manual

open access: yes, 2020
We present a history of thermodynamics. Part 1 discusses definitions, a pre-history of heat and temperature, and steam engine efficiency, which motivated thermodynamics.

Second law of thermodynamics and the failure of rock materials [PDF]

open access: yes, 2001
The relation of nonequilibrium thermodynamics to some failure and fracture theories of rock mechanics is investigated. The basic concepts are given to connect failure to the properties of material equations describing the elastic properties.

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Modeling, Simulation, and Reconstruction of 2-Reservoir Heat-to-Power Processes in Finite-Time Thermodynamics [PDF]

open access: yes, 2020
The connection between endoreversible models of Finite-Time Thermodynamics and the corresponding real running irreversible processes is investigated by introducing two concepts which complement each other: Simulation and Reconstruction.

Complex Time Approach to the Hamiltonian and the Entropy Production of the Damped Harmonic Oscillator

open access: yesEntropy
The present work applies and extends the previously developed Quantitative Geometrical Thermodynamics (QGT) formalism to the derivation of a Hamiltonian for the damped harmonic oscillator (DHO) across all damping regimes.

Adsorption model for multi-component heavy metal ions on clay based on non-equilibrium thermodynamics

open access: yesYantu gongcheng xuebao, 2019
The adsorption behavior of clay particles is the key factor to control the solute transport, which can further affect the accurate evaluation of the long-term service performance of the seepage prevention barrier. Based on the single-component adsorption
