Dynamic oscillatory shear tests are common in rheology and have been used to investigate
a wide range of soft matter and complex fluids including polymer melts and solutions, block …

There is considerable experimental evidence that the classical no-slip boundary condition of
fluid mechanics is not always a valid assumption for the flow of high molecular weight …

Above the critical stress for slip, the procedures normally used to analyze the results of
capillary flow data give anomalous results. In particular, the Bagley plots are curved, even …

The assumption that a liquid adheres to a solid boundary (“no-slip” boundary condition) is
one of the central tenets of the Navier-Stokes theory. However, there are situations wherein …

Polymers and rheology were both born in the twenties of the last century, fruit of the
disruptive and creative scientific atmosphere of this decade. The development of polymer …

In polymer solutions or blends, flow can strongly influence the degree of mixing of the
components. In a shearing flow, droplets in a dispersion can be broken down to sizes …

Polymer surfaces and interfaces have many technological applications. In the present article
we review some recent experiments conducted on model systems with the aim of …

This paper explores the molecular mechanism for sharkskin formation on extrudate of linear
low density polyethylenes (LLDPE) and investigates the rheological origin of a characteristic …

This article reviews recent results on capillary melt flow anomalies. Long standing
controversies and debates in this field are illustrated by summarizing previous results and …

During flow, an initially homogeneous polymer solution may develop position-dependent
concentration gradients due to migration of the polymer molecules with respect to the bulk …
