Specific refractive index increments of inulin [PDF]

Journal 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.

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

Journal 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.

Re-evaluation of experimental data on the second virial coefficient for steam and development of its analytical representation as a function of the internal energy

EPJ Web of Conferences, 2013
A re-evaluation of the second virial coefficient of steam is presented in the paper. The work is a part of broader effort to develop a formulation of the properties of dry and metastable steam suitable for CFD computations.

Thermodynamic Properties of the Parabolic-Well Fluid

Frontiers in Physics, 2021
The thermodynamic properties of the parabolic-well fluid are considered. The intermolecular interaction potential of this model, which belongs to the class of the so-called van Hove potentials, shares with the square-well and the triangular well ...

Comment on "Statistical Mechanics of Non-Abelian Chern-Simons Particles" [PDF]

, 1995
The second virial coefficient for non-Abelian Chern-Simons particles is recalculated. It is shown that the result is periodic in the flux parameter just as in the Abelian theory.Comment: 3 pages, latex ...

S-matrix poles and the second virial coefficient [PDF]

, 2001
For cutoff potentials, a condition which is not a limitation for the calculation of physical systems, the S-matrix is meromorphic. We can express it in terms of its poles, and then calculate the quantum mechanical second virial coefficient of a neutral ...

Studies of radial distribution function and second virial coefficient for surfactant decyltrimethylammonium bromide in aqueous solutions at 298.15 K: Evidence for cation–cation hydrophobic interactions effect

Chemical Thermodynamics and Thermal Analysis, 2022
Excess internal pressure of solution and excess partial molar volume of solute data embedded in the parameter reversible isothermal work (W) have been used to calculate the ion–ion pair correlation functions (gij(r), r being distance) and the ...
