Geometric pumping induced by shear flow in dilute liquid crystalline polymer solutions [PDF]
, 2014 We investigate nonlinear rheology of dilute liquid crystalline polymer solutions under time dependent two-directional shear flow. We analyze the Smoluchowski equation, which describes the dynamics of the orientation of a liquid crystalline polymer, by ...

A rationale for the preparation of asymmetric pervaporation membranes [PDF]
, 1985 Pervaporation is carried out primarily with homogeneous membranes. An improvement in permeation rate can be achieved by using asymmetric or composite membranes. In order to maintain a high selectivity, very dense top layers are needed.
