On the electrical conductivity and schlieren texture of some lyotropic nematic mesophases

In the article published in Czechoslovak Journal of Physics (1998) by A. Nesrullajev and N. Kazanci [1], previously published electrical conductivity data for a lyotropic nematic mesophase based on a specific amphiphilic substance were presented as original data for a lyotropic system based on a different amphiphilic substance. The same co-authors also presented the schlieren texture for Nc mesophase in Ref. [1] as if an original micrograph was belonging to Nc mesophases based on different amphiphilic matrials in their article published in other journals.
