Renormalization group evaluation of the second virial coefficient of polydisperse polymer solutions
2014 The second virial coefficient A2 for a mixture of two monodisperse polymers is studied by means of the renormalization group. It is found that the cross-term A12 has a finite limit if the segment number of one of the polymers tends to infinity. Such behaviour predicts a maximum of A2 in dependence on the relative composition of the polymers. The maximum resulting from our firstorder RG-cal...
متن کاملSecond virial coefficient studies of cosolvent-induced protein self-interaction.
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. Although second virial coefficient studies can supply invaluable quantitative information, their emergence as a systematic approach to evaluating protein self-interaction has been slowed by the limitations of tradi...
متن کاملSome comments on the second virial coefficient of semiflexible polymers.
A Monte Carlo study is made of the mean-square radius of gyration S(2) and second virial coefficient A(2) for the two freely rotating chains with the Lennard-Jones (LJ) 6-12 potential and the hard-sphere (HS) one in the range of the bond angle theta from 109 degrees (typical flexible chain) to 175 degrees (typical semiflexible or stiff chain) and in the range of the number n of bonds from 6 to ...
متن کاملHaldane exclusion statistics and second virial coefficient.
We show that Haldanes new definition of statistics, when generalised to infinite dimensional Hilbert spaces, is equal to the high temperature limit of the second virial coefficient. We thus show that this exclusion statistics parameter, g , of anyons is non-trivial and is completely determined by its exchange statistics parameter α. We also compute g for quasiparticles in the Luttinger model an...
متن کاملNonmonotonic variation with salt concentration of the second virial coefficient in protein solutions.
The osmotic virial coefficient B2 of globular protein solutions is calculated as a function of added salt concentration at fixed pH by computer simulations of the "primitive model." The salt and counterions as well as a discrete charge pattern on the protein surface are explicitly incorporated. For parameters roughly corresponding to lysozyme, we find that B2 first decreases with added salt con...
