The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

A New Piecewise EOS for Compressibility Factor Prediction Based on the M-factor Theory [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2010
In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed.

Path-integral calculation of the third virial coefficient of quantum gases at low temperatures

, 2011
We derive path-integral expressions for the second and third virial coefficients of monatomic quantum gases. Unlike previous work that considered only Boltzmann statistics, we include exchange effects (Bose-Einstein or Fermi-Dirac statistics).

Virial expansions and augmented van der Waals approach: Application to Lennard-Jones-like Yukawa fluid [PDF]

, 2015
We argue that recently proposed [Melnyk et al., Fluid Phase Equilibr., 2009, Vol. 279, 1] a criterion to split the pair interaction energy into two parts, one of which is forced to be responsible the most accurate as possible for excluded volume energy ...

Determination of chain conformation of polysaccharides using a SEC‐MALLS‐Vis

Food Biomacromolecules, EarlyView.
Abstract For polysaccharides, biological activity is associated with the chemical structure as well as the chain conformation. The chain conformation is conventionally derived from the scaling relationships between weight‐average molecular weight (Mw) and intrinsic viscosity ([η]) or the radius of gyration (Rg) or the translational diffusion ...

Antibody association in solution: cluster distributions and mechanisms

mAbs
Understanding factors that affect the clustering and association of antibodies molecules in solution is critical to their development as therapeutics. For 19 different monoclonal antibody (mAb) solutions, we measured the viscosities, the second virial ...

The Liquid Density of Complex Liquid Mixtures [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1998
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid ...

Ideal quantum gases in two dimensions

, 1994
Thermodynamic properties of non-relativistic bosons and fermions in two spatial dimensions and without interactions are derived. All the virial coefficients are the same except for the second, for which the signs are opposite.

Too close for comfort: Self‐crowding transforms protein structure and stability beyond volume exclusion

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Proteins operate in crowded physiological environments, yet their conformational and oligomeric states are largely inferred from experiments performed under dilute buffer conditions. Here, we show that for lysozyme (LYS) and bovine serum albumin (BSA), self‐crowding at physiologically relevant concentrations alters protein structure and ...
