Iterated Stretching and Multiple Beads-on-a-String Phenomena in Dilute Solutions of Highly-Extensible Flexible Polymers
(2005-04-13)
The dynamics of elastocapillary thinning in high molecular weight polymer solutions are re-examined
using high-speed digital video microscopy. At long times, the evolution of the viscoelastic thread deviates from self-similar ...
Ex vivo Rheology of Spider Silk
(2005-08-05)
We investigate the rheological properties of microliter quantities of the spinning
material extracted ex vivo from the major ampullate gland of a Nephila clavipes spider
using two new micro-rheometric devices. A sliding ...
