DOI: 10.1039/d2sm01600a

Abstract: Novel modulated nematic phases, such as twist-bend nematics, splay-bend nematics and splay nematics, are an important subject of research in the field of liquid crystals. In this article fundamental information about the discovery, structure and… read more here.

DOI: 10.1080/02678292.2020.1836279

Abstract: ABSTRACT Conoscopic images have confirmed the occurrence of biaxial positive ( and biaxial negative ( ) nematic phases between the two uniaxial nematic (discotic – and calamitic – ) phases. Biaxial positive ( ) nematic… read more here.

DOI: 10.1103/physreve.105.064701

Abstract: We have elaborated a theoretical approach for the description of polar nematic phases observed by Nishikawa et al. [Adv. Mater. 29, 1702354 (2017)0935-964810.1002/adma.201702354], their structures, and transitions between them. Specific symmetry contributions to the pair molecular… read more here.
