Usatenko<br/>The massive field theory approach in fixed space dimensions d<4 is applied to investigate a dilute solution of long-flexible polymer chains in a good solvent between two parallel repulsive walls, two inert walls, and for the mixed case of one inert and one repulsive wall. The well-known correspondence between the field theoretical ϕ^{4} O(n) -vector model in the limit n→0 and the behavior of long-flexible polymer chains in a good solvent is used to calculate the depletion interaction potential and the depletion force up to one-loop order. In order to make the theory UV finite in renormalization-group sense in 3≤d<4 dimensions we performed the standard mass renormalization and additional surface-enhancement constants renormalization. Besides, our investigations include modification of renormalization scheme for the case of two inert walls. The obtained results confirm that the depletion interaction potential and the resulting depletion force between two repulsive walls are weaker for chains with excluded volume interaction (EVI) than for ideal chains because the EVI effectively reduces the depletion effect near the walls. Our results are in qualitative agreement with previous theoretical investigations, experimental results, and with the results of Monte Carlo simulations.<br/>[Phys. Rev.

Ostwal, Muhammad Sahimi, and Theodore T. Tsotsis<br/>The results of extensive molecular simulations of adsorption and diffusion of water vapor in polyaniline, made conducting by doping it with HCl or HBr over a broad range of temperatures, are reported. The atomistic model of the polymers was generated using energy minimization, equilibrium molecular ...<br/>[Phys. Rev. E 79, 061801] Published Wed Jun 03, 2009 Mayur M.

Aichele, A. Cavallo, A. Johner, J. Baschnagel, and J. P. Wittmer<br/>Self-avoiding polymers in two-dimensional (d=2) melts are known to adopt compact configurations of typical size R(N)∼N^{1/d} , with N being the chain length. Using molecular-dynamics simulations we show that the irregular shapes of these chains are characterized by a perimeter length L(N)∼R(N)^{...<br/><img src="http://prola.aps.org/graphics/rapid30x30.gif" width="30" height="30" alt="Rapid Communication"/><br/>[Phys.
