Diffusion in polymer-diluent systems
TL;DR: In this article, the authors discuss some selected topics with which they have a relatively greater acquaintance but which they feel are of fundamental importance for understanding the current situation in this field of polymer research.
Journal ArticleDOI
Diffusion and relaxation in glassy polymer powders: 2. Separation of diffusion and relaxation parameters
A.R Berens,H.B Hopfenberg +1 more
TL;DR: In this article, a model involving a linear superposition of one or two phenomenologically independent first order relaxation terms upon the ideal Fickian diffusion equation was proposed to describe the individual contributions of the diffusion and relaxation processes.
Journal ArticleDOI
A critical discussion of the physics of wood–water interactions
TL;DR: The authors reviewed recent findings on wood-water interaction and put them into context of established knowledge in the field, and several new findings challenge prevalent theories and are critically discussed in an attempt to advance current knowledge and highlight gaps.
Journal ArticleDOI
Kinetics of drug release from hydrogel matrices
TL;DR: The kinetics of drug release from hydrogel matrices will be examined both experimentally and theoretically and special emphasis will be placed on the effect of local drug concentration on the swelling behavior ofhydrogel drug carriers.
Journal ArticleDOI
Sorption and transport in glassy polymers–a review
TL;DR: In this paper, the authors define Fickian diffusion in rubbery polymers and present a review and classification of various theoretical models which have been proposed to account for these phenomena.
