Optical experiments on free-standing liquid crystal films which address the issues of structural ordering, fluctuations in two dimensions and enhanced surface ordering will be reviewed.

Detailed measurements of shear-thinning viscoelastic aqueous solutions, with relatively low zero- shear viscosity allowing for uncharacteristically high Weissenberg number in microchannel flow are

Polymer fluid mechanics is of primary importance to processing operations which range from extrusion and fiber spinning to packaging microelectronic devices.

A similarity transform is used to analyze the flow of an upper- convected Maxwell fluid in an infinitely-long cylinder whose surface has a velocity that increases in magnitude linearly with axial c

The current understanding of viscoelastic phenomena in dilute solutions of polymers is reviewed.

Viscoelastic relaxation of concentrated polymer systems requires the disentanglement of the polymers.

The three viscometric coefficients for the disordered phase of a diblock copolymer melt near its critical point are calculated from a dynamical mean field theory.

The viscosity and density of a congruently melting lithium niobate liquid were measured from 1270C to 1370C.

New multicomponent PbF2-InF3-GaF3 bulk glasses have been investigated. They show lower phonon energy (540 cm(-1)) in comparison with 580 cm(-1) for ZBLAN.

A polyacrylamide hydrogel in which double-stranded DNA replaces bis(acrylamide) as the crosslinker has been developed.
