摘要:

The radiotracer impurity diffusion coefficients D11= D22and D33in 4-n-pentyl-4-cyanobiphenyl (5CB), 4-n-octyl-4-cyanobiphenyl (8CB), 4-n-pentyloxy-4-cyanobiphenyl (50CB), and 4-n-octyloxy-4-cyanobiphenyl (80CB) have been determined over their nematic phase. An electromagnet was used for the particles orientation and diffusion of impurity which was water solution of natrium pertechnate (NaTcO4), traced with Tc - 99m was investigated.
