The recent theoretical prediction by Maimbourg and Kurchan [e-print arXiv:1603.05023 (2016)] that for regular pair-potential systems the virial potential-energy correlation coefficient increases towards unity as the dimension d goes to infinity is investigated for the standard 12-6 Lennard-Jones fluid. This is done by computer simulations for d = 2, 3, 4 going from the critical point along the ...

Polyhedral oligomeric silsesquioxanes show promising applications as organic-inorganic nanocomposite building blocks that can be used, for example, to enhance the properties of polymeric materials. In this work radial distribution functions, potentials of mean force, and self-diffusion coefficients are obtained from molecular dynamics simulations for polyhedral oligomeric silsesquioxane (POSS) ...

This work re-examines the classical problem of polymer collapse in a random system, using a Gaussian variational formalism to treat the ‘‘poor solvent’’ case. In particular we seek to clarify some of the disputed questions related to symmetry breaking between the replicas used to analyze such quenched systems, and the scaling of the globular collapse with the disorder strength. We map the rando...

The effects of ammonium sulphate concentration on the osmotic second virial coefficient (BAA/MA) for equine serum albumin (pH 5.6, 20 degrees C) have been examined by sedimentation equilibrium. After an initial steep decrease with increasing ammonium sulphate concentration, BAA/MA assumes an essentially concentration-independent magnitude of 8-9 ml/g. Such behaviour conforms with the statistica...
