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.

Energy generation characteristics of pressure retarded osmosis using polymer solution

open access: yesJournal of Fluid Science and Technology, 2022
Research on energy generation characteristics based on pressure retarded osmosis (PRO) using seawater is being widely carried out. However, there are few studies that use polymer solutions.

Tuning the Mechanical Properties of Crosslinked Copolymers via Sequence and Solvent‐Selective Swelling for Vat Photopolymerization

open access: yesAngewandte Chemie, EarlyView.
Polymer sequence and solvent selectivity independently modulate pendant‐vinyl accessibility during photocuring, trapping different topologies in CLIP and controlling mechanical properties. ABSTRACT Block copolymers (BCPs) offer distinct advantages for vat photopolymerization by enabling mechanically programmable network structures through microphase ...

Effects of the second virial coefficient on the adiabatic lapse rate of dry atmospheres [PDF]

open access: yes, 2019
We study the effect of the second virial coefficient on the adiabatic lapse rate of a dry atmosphere. To this end, we compute the corresponding adiabatic curves, the internal energy, and the heat capacity, among other thermodynamic parameters.

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

open access: yesEPJ 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.
