On the relation between virial coefficients and the close-packing of hard disks and hard spheres

, 2011
The question of whether the known virial coefficients are enough to determine the packing fraction $\eta_\infty$ at which the fluid equation of state of a hard-sphere fluid diverges is addressed.

Cluster Formation and The Virial Equation of State of Low-Density Nuclear Matter

, 2005
We present the virial equation of state of low-density nuclear matter composed of neutrons, protons and alpha particles. The virial equation of state is model-independent, and therefore sets a benchmark for all nuclear equations of state at low densities.

Trapping a Metastable Node in an Amorphous Metal–Organic Framework

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.

A Density Functional Theory‐Based Investigation of a pH‐ and Redox‐Driven Tristable [2]Rotaxane in CH2Cl2 Dilute Solution [PDF]

ChemistryOpen
A recently proposed pH‐ and redox‐driven tristable [2]rotaxane in CH2Cl2 dilute solution is investigated, combining converged Density Functional Theory (DFT)‐based electronic eigenstates. The theoretical picture that has emerged allows to identify the local supramolecular interaction patterns capable of modulating the mutual position of a DB24C8 ...

Inductive Construction of 2-Connected Graphs for Calculating the Virial Coefficients

, 2010
In this paper we give a method for constructing systematically all simple 2-connected graphs with n vertices from the set of simple 2-connected graphs with n-1 vertices, by means of two operations: subdivision of an edge and addition of a vertex.

Kinetic equation consistent with the equation of state of nuclear matter [PDF]

, 1998
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.

Cluster virial expansion for the equation of state of partially ionized hydrogen plasma

, 2010
We study the contribution of electron-atom interaction to the equation of state for partially ionized hydrogen plasma using the cluster-virial expansion.

A Novel Green Method for Producing Medical‐Grade Chitosan From Loligo plei Squid Pens

Journal of Applied Polymer Science, EarlyView.
This work demonstrates a sustainable and simplified process for the production of medical‐grade chitosan from the feathers of the squid Loligo plei, employing mild chemical treatments to preserve the integrity of the polymer while achieving high purity and performance.

The Fractional Virial Potential Energy in Two-Component Systems [PDF]

Serbian Astronomical Journal, 2008
Two-component systems are conceived as macrogases, and the related equation of state is expressed using the virial theorem for subsystems, under the restriction of homeoidally striated density profiles.
