Systematic characterization of drug release profiles from finite-sized hydrogels

Casault, Sébastien; Slater, Gary W. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 22, pp. 5387-5402

simulated hydrogels and diffusion is modeled using an exact enumeration scheme. We show the fitting parameters to be largely …

A simple and exactly solvable model for a semiflexible polymer chain interacting with a surface

Mishra, P.K.; Kumar, S.; Singh, Y. - In: Physica A: Statistical Mechanics and its Applications 323 (2003) C, pp. 453-465

We use the lattice model of directed walks to investigate the conformational as well as the adsorption properties of a semiflexible homopolymer chain immersed in a good solvent in 2D and 3D. To account for the stiffness in the chain we have introduced energy barrier for each bend in the walk and...

Does a surface attached globule phase exist?

Mishra, P.K.; Giri, D.; Kumar, S.; Singh, Y. - In: Physica A: Statistical Mechanics and its Applications 318 (2003) 1, pp. 171-178

A long flexible neutral polymer chain immersed in a poor solvent and interacting with an impenetrable attractive surface exhibits a phase known as surface attached globule (SAG) in addition to other adsorbed and desorbed phases. In the thermodynamic limit, the SAG phase has the same free energy...
