Shear orientation and lyotropic hexagonal phases
Article Abstract:
A study was conducted to determine the influence of shear on the micellar hexagonal phase structure of liquid crystals. The hexagonal liquid crystal phases of two surfactants were analyzed. Several techniques were used to perform this task namely, deuterium nuclear magnetic resonance, birefringence, microscopy, small-angle neuron scattering and small-angle light scattering. The rodlike micelles were observed to be positioned along the flow direction. Also, the shear orientation correlation perpendicular to the flow direction was longer than the diameter of a micelle.

Effect of flow reversal on the shear induced formation of multilamellar vesicles
Article Abstract:
The influence of rate controlled flow reversal on the transition from planar lamellae to multilamellar vesicles using a nonionic lamellae phase consisting of 40 wt percent triethylene glycol monodecyl is investigated. The exponential scaling of the strain needed to reach characteristic states of the transition with strain amplitude seems to hold for all length scales involved in the process.

Direct evidence by layer-by-layer assembly of polyelectrolyte multilayers on soft and porous temperature-sensitive PNiPAM microgel using fluorescence correlation spectroscopy
Article Abstract:
The layer-by-layer assembly of polyelectrolyte multilayers on soft and porous temperature-sensitive poly(N-isopropylacrylamide) (PNiPAM) microgel is described. Fluorescence correlation spectroscopy is used for distinguishing free labeled polyelectrolytes and those bound to the microgel.
