TL;DR: In this article, the authors show that it is only correlation of molecular parameters with the rheological material functions that allows structure-property relationships to be established, which then make it possible to describe the flow behaviour of cellulose derivative solutions in detail.

TL;DR: In this paper, the authors investigated the concentration dependence of the characteristic relaxation time of dilute polymer solutions in transient uniaxial elongational flow and proposed a criterion for a lower sensitivity limit, in the form of a minimum concentration cmin necessary for experimental resolution of the effects of polymeric viscoelasticity.

TL;DR: In this paper, high-precision measurements of this beads-on-string structure are combined with a theoretical analysis of the limiting case of large polymer relaxation times and high polymer extensibilities, for which the evolution can be divided into two distinct regimes.

TL;DR: A mechanical model is presented that captures the key features of adhesive locomotion and suggests that the most important properties for optimal inclined locomotion are a large, reversible yield stress, followed by a small shear viscosity and a short thixotropic restructuring time.
