Exact ODE Framework for Classical and Quantum Corrections for the Lennard-Jones Second Virial Coefficient [PDF]
EntropyThe second virial coefficient (SVC) of the Lennard-Jones fluid is a cornerstone of molecular theory, yet its calculation has traditionally relied on the complex integration of the pair potential. This work introduces a fundamentally different approach by

Selecting temperature for protein crystallization screens using the temperature dependence of the second virial coefficient. [PDF]
PLoS ONE, 2011 Protein crystals usually grow at a preferable temperature which is however not known for a new protein. This paper reports a new approach for determination of favorable crystallization temperature, which can be adopted to facilitate the crystallization ...

On the First Quantum Correction to the Second Virial Coefficient of a Generalized Lennard-Jones Fluid [PDF]
EntropyWe derive an explicit analytic expression for the first quantum correction to the second virial coefficient of a d-dimensional fluid whose particles interact via the generalized Lennard-Jones (2n,n) potential.

On the Calculation of the Virial Coefficients and Low-Pressure Joule-Thomson Effect for Refrigerant Fluids Using Two Equation of State Models [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 In this study, we calculate virial coefficients and the Joule-Thomson effect at low pressure for refrigerant fluids in order to evaluate the performance of two models of Equations of State (EOS). The studied refrigerants are R123, R124, R143a, and R152a.

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