Molecular simulation of chevrons in confined smectic liquid crystals.
Chevron structures adopted by confined smectic liquid crystals are investigated via molecular dynamics simulations of the Gay-Berne model. The chevrons are formed by quenching nematic films confined between aligning planar substrates whose easy axes have opposing azimuthal components. When the substrates are perfectly smooth, the chevron formed migrates rapidly towards one of the confining wall...
متن کاملObservation of molecular layering in a confined water film and study of the layers viscoelastic properties
A transverse dynamic force microscope, more commonly known as shear force microscope, has been used to investigate confined water films under shear. A cylindrically tapered glass probe was mounted perpendicularly to the sample surface. Pure water was confined between the probe and a freshly cleaved mica surface and a sinusoidal shear strain was applied by setting the probe into transverse oscil...
متن کاملA simple molecular theory of smectic C liquid crystals
In the previous chapters we have described several novel phase transitions exhibited by compounds with molecules having longitudinal components of permanent electric dipole moments. As described in Chapter-1, in the smectic C (SmC) phase, the constituent molecules are tilted in the smectic layers. The SmC liquid crystal is made of compounds with molecules having lateral components of dipole mom...

متن کاملGlasslike Transition of a Confined Simple Fluid.
A simple globular-shaped liquid (octamethylcyclotetrasiloxane, OMCTS) was placed between two solid plates at variable spacings comparable to the size of this molecule and the linear shear viscoelasticity of the confined interfacial film was measured. Strong monotonic increase of the shear relaxation time, elastic modulus, and effective viscosity were observed at spacings less than about 10 mole...
