New lyotropic mixtures with non-chiral N-acylamino acid surfactants presenting the biaxial nematic phase investigated by laser conoscopy, polarized optical …
Abstract: Amino acid-based surfactants were used as the main surfactants to prepare new lyotropic mixtures presenting three nematic phases. One of them is biaxial (NB), and the two others are uniaxial, discotic (ND) and calamitic (NC). These surfactants were the non-chiral
