Capillary oscillations and instabilities of discotic liquid crystal threads
نویسندگان
چکیده
2014 Mechanical experiments on thin threads in discotic liquid crystal are described. Thread resonance under oscillating electric field excitation allows the measurement of the surface tension. Buckling instabilities are observed under mechanical compression and also under magnetic field. All these effects, dominated by surface tension after plastic relaxation, are characteristic of the discotic ordering which ensures the thread stability. J. Phys.

Orientational Order Parameter Measurements of Discotic Liquid Crystal
The IR dichroism technique is a convenient method which can be used to measure the molecular order parameter corresponding to the IR bands exclusively present in the disc –like molecules in discotic liquid crystal (DLC). To measure orientational order parameter, homeotropic alignment of discotic liquid crystal was attained by slow cooling of sample from isotropic phase on untreated flat CaF2 su...
متن کاملCapillary instabilities in thin nematic liquid crystalline fibers.
A complete identification and characterization of three distinct capillary instabilities in nematic liquid crystal fibers is presented. Linear stability analysis of capillary instabilities in thin nematic liquid crystalline cylindrical fibers is performed by formulating and solving the governing nematocapillary equations. A representative axial nematic orientation texture is studied. The surfac...
متن کاملObservation of an anchoring transition in a discotic liquid crystal
– We report the anchoring transition in a discotic liquid crystal, hexapentyloxytriphenylene (HPT), from edge-on to side-on alignment in a discotic phase. The topology, easy direction of orientation and the coating of the substrate with a polymer are the determining factors for the alignment and the anchoring transition in a discotic liquid crystal. Discotic liquid crystals are perfect examples...
متن کاملTheory and Simulation of Extensional Flow-Induced Biaxiality in Discotic Mesophases
Flow-induced biaxiality is simulated for a uniaxial discotic nematic liquid crystal subjected to a constant uniaxial, isothermal, incompressible, irrotational, extensional, three dimensional flow, using a previously presented model [Singh A-Pand Rey A D., J Phys. II
متن کاملRecent Advances in Discotic Liquid Crystal-Assisted Nanoparticles
This article primarily summarizes recent advancement in the field of discotic liquid crystal (DLC) nanocomposites. Discotic liquid crystals are nanostructured materials, usually 2 to 6 nm size and have been recognized as organic semiconducting materials. Recently, it has been observed that the dispersion of small concentration of various functionalized zero-, one- and two-dimensional nanomateri...
