Evidence of Many-Body Interactions in the Virial Coefficients of Polyelectrolyte Gels

open access: yesGels, 2022
Simulation studies of aqueous polymer solutions, and heuristic arguments by De Gennes for aqueous polyethylene oxide polymer solutions, have suggested that many-body interactions can give rise to the ‘anomalous’ situation in which the second osmotic ...

Second virial coefficient studies of cosolvent-induced protein self-interaction. [PDF]

open access: yesBiophys J, 2005
Protein self-interaction is important in protein crystal growth, solubilization, and aggregation, both in vitro and in vivo, as with protein misfolding diseases, such as Alzheimer’s.

Unified analytical formulae of second virial coefficient with kihara potential and its application to real gases

open access: yes, 2020
We propose a general evaluation method to calculate the second virial coefficient with Kihara potential (spherical core). The suggested approach is based on exponential function series expansion formula and gamma functions, which enable us to have ...

Determination of the Second Virial Coefficient for Binary Mixtures of Ar with CH4 and CO using Van der Waals and Dieterici Models [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2019
In this paper, we calculate the second virial coefficient for binary mixtures of Ar with CH4 and CO in order to evaluate the performance of equations of state (EOSs).

Calculation of propellant gas pressure by simple extended corresponding state principle

open access: yesDefence Technology, 2016
The virial equation can well describe gas state at high temperature and pressure, but the difficulties in virial coefficient calculation limit the use of virial equation.

Calculations of thermophysical characteristics of xenon [PDF]

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2018
On the basis of a generalization of thermodynamics in fractional derivatives and some analytical expressions obtained, taking into account the second virial coefficient B, we calculated thermophysical characteristics of a noble gas xenon Xe: entropy S ...

On Using the BMCSL Equation of State to Renormalize the Onsager Theory Approach to Modeling Hard Prolate Spheroidal Liquid Crystal Mixtures

open access: yesEntropy, 2021
Modifications to the traditional Onsager theory for modeling isotropic–nematic phase transitions in hard prolate spheroidal systems are presented. Pure component systems are used to identify the need to update the Lee–Parsons resummation term.

Specific refractive index increments of inulin [PDF]

open access: yesJournal of the Serbian Chemical Society, 2001
The specific refractive index increments (dn/dc) of inulin in water, at 25 ºC, were measured at different wavelengths (436, 546 and 589 nm) using a BP-differential refractometer.

Analysis of p, T, ρ-data for all fluid states via comparison with a transcribed Van der Waals equation

open access: yesChemical Thermodynamics and Thermal Analysis, 2021
The old concepts of the Van der Waals equation (vdW EOS) and of the virial equation, truncated to the second virial coefficient, can be rewritten with a function defined as cc=(p−R·T/M)/ρ2. This function arises from introducing the ideal gas law into the

Thermophysical Properties of Light and Heavy Water from Second Virial Coefficient; Isotopic Substitution Effect [PDF]

open access: yesJournal of Nuclear Research and Applications
In this paper, some thermophysical properties of light and heavy water will be predicted and modeled using the virial equation of state (VEOS), and the effect of isotopic substitution will be studied.
