The Beads-on-String Structure of Viscoelastic Threads
(2007-01-23)
By adding minute concentrations of a high molecular weight polymer, liquid jets or bridges collapsing under the action of surface tension develop a characteristic shape of uniform threads connecting spherical
uid drops. ...
How Dilute are Dilute Solutions in Extensional Flows?
(2007-01-23)
We investigate the concentration-dependence of the characteristic relaxation time of
dilute polymer solutions in transient uniaxial elongational flow. A series of monodisperse polystyrene solutions of five different ...
