WebAlthough the 5CB-rich phase crystallizes mostly at low temperatures, some 5CB-rich droplets of a small size remain without crystallization and exhibit dielectric relaxations termed β and γ. The β and γ processes are assigned to rotation of the 5CB molecules around the short and long axes of the rodlike 5CB molecule, respectively. WebAug 26, 2005 · We measure the electric-field-driven annihilation of nematic disclination pairs with strength +/- 1/2 in the 4-cyano-4'-n-pentylbiphenyl (5CB) liquid crystal. The use of a very weak azimuthal anchoring ensures a two-dimensional director field. The relaxation is governed by the formation of a pi wall connecting the two opposite charge defects. hellen lukoma songs https://euromondosrl.com
