Shear Viscosity of the Homologous Series of nCHBT (n = 0 ÷ 12) in the Isotropic and Nematic Phases

We may thus conclude that both the viscosity and ro- tation suppress the instability of the superposed grav- itating streams when the streams rotate about an axis in the

It is shown that the viscosity (at constant temperature) and activation energy of the viscosity show a quite different dependence on the length of the alkane chain in 1,2- and

The relaxation spectra for the isotropic phase of 1 OCB were collected in the frequency range 10 MHz – 5 GHz with a time domain spectrometer (TDS) at Uppsala University, as

In the isotropic phase the dielectric and viscosity data allow one, in the framework of the Debye model, to estimate the effective length of 6CB molecule. Key words:

The ratio absolute diffusion depends on the aspect ratio of the rods and the difference between the hydrodynamic diameter d hyd , which is the diameter probed by the solvent

At higher shear rates a transition was predicted between this tumbling region and a regime where the di- rector is wagging between two relatively small angles, and to flow alignment
