Helmholtz free energies of atom pair interactions in proteins

Folding and Design, 1996
Proteins fold to unique three-dimensional structures, but how they achieve this transition and how they maintain their native folds is controversial. Information on the functional form of molecular interactions is required to address these issues. The basic building blocks are the free energies of atom pair interactions in dense protein solvent systems.

Adsorption in Slit Pores and Pore-Size Distribution: A Molecular Layer Structure

Adsorption Science & Technology, 2006
Anew approach is developed to analyze the thermodynamic properties of a sub-critical fluid adsorbed in a slit pore of activated carbon. The approach is based on a representation that an adsorbed fluid forms an ordered structure close to a smoothed solid ...

Maximal forces and thermodynamic quantities of specific black holes in modified theories of gravity

Nuclear Physics B, 2023
In this work, we explore the maximum force conjecture and thermal fluctuations for different black holes such as the brane-world black hole, de Rham-Gabadadze-Tolley black hole, Black-Bounce Reisner-Nordström black hole, and renormalization group ...

Critical equation of state of randomly dilute Ising systems

, 2003
We determine the critical equation of state of three-dimensional randomly dilute Ising systems, i.e. of the random-exchange Ising universality class. We first consider the small-magnetization expansion of the Helmholtz free energy in the high-temperature

The structure of force-free magnetic fields [PDF]

, 2000
Incontrovertible evidence is presented that the force-free magnetic fields exhibit strong stochastic behavior. Arnold’s solution is given with the associated first integral of energy.

Helmholtz and Gibbs free energies of liquid foams

Philosophical Magazine Letters, 2004
The relative stability of different configurations (i.e. geometries/topologies) of a foam cluster is shown to depend on the choice of constraints, viz. fixed bubble and Plateau border sizes, or fixed bubble and Plateau border pressures. The appropriate thermodynamic potential is the Gibbs free energy, which comprises the (Helmholtz) surface energy plus

Electron-phonon interactions and Helmholtz free energy in confined systems: Advancing low-dimensional superconductors for quantum technologies

Results in Physics
The thermodynamic and superconducting properties of low-dimensional superconductors are profoundly influenced by electron–phonon interactions, which play a critical role in determining the Helmholtz free energy.

Application of Fractional Calculus to Establish Equations of State for Solid Metals

Fractal and Fractional, 2023
Fractional differ-integral operators are used to obtain the equation of state for a substance that can be seen as fractal. Two equations of state have been obtained, the first of which depends on two parameters that characterize the fractal dimension of ...

Thermodynamic insight into stimuli-responsive behaviour of soft porous crystals

Nature Communications, 2018
Knowledge of the thermodynamic potential is crucial to characterize the macroscopic state of soft porous crystals. Here, the authors present a generalized thermodynamic approach to construct the Helmholtz free energy and identify the conditions under ...
