We discuss the symmetry properties as well as the dynamic behavior of various non-polar nematic liquid crystal phases with tetrahedral order. We concentrate on systems that show biaxial nematic order coexisting with octupolar (tetrahedral) order. Non-polar examples are phases with D2 and S4 symmetries, which can be characterized as biaxial nematics lacking inversion symmetry. It is this combina...

The search for prebiotic, nucleic acid precursors is, at its best, a speculative undertaking. Given the complex structure of RNA, it is not very likely that RNA was the first information system in the universe and thus finding possible precursor/s i.e. pre-RNA remains an open challenge. We, in this paper, have tried to construct nucleic acid polymers with a simple acyclic, achiral backbone. Suc...

This perspective reports on recent progress toward the development of an approach to a priori predict - both chirality “strength” and efficacy transfer from chiral nanoshape solute achiral nematic environment.

Chiral lanthanide complexes can be prepared by choosing the achiral antenna ligand and chiral inducer independently. With this modular approach, optimized for use in efficient CP-OLEDs may obtained.

We have shed light on the recent advances in imprinting chirality into achiral inorganic nanomaterials using organic chiral molecules, their structural analysis, growth mechanism, optical, optoelectronic, and bio-applications.

The noble electrochemical doping agent enables stable of achiral π-CP in π-CP:aza[6]H blends, which allows better charge injection and balance for efficient circularly polarized optoelectronic devices.

A classification scheme relating the chirality of molecules to type crystal structures (chiral or achiral) they may form is presented. With respect similar classifications proposed in past, some corrections and extensions are introduced. In particular, (1) it shown that chiral from achiral can occur 28 types space group having screw axes n p , with ? /2, not any Sohncke group; (2) restriction o...

Bestowing chirality to metals is central in fields such as heterogeneous catalysis and modern optics. Although the bulk phase of metals is symmetric, their surfaces can become chiral through adsorption of molecules. Interestingly, even achiral molecules can lead to locally chiral, though globally racemic, surfaces. A similar situation can be obtained for metal particles or clusters. Here we rep...

A substrate coated with an achiral polyimide alignment layer was scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid crystal orientation. The resulting noncentrosymmetric topography resulted in a chiral surface that manifests itself at the molecular level. To show this unambiguously, a planar-aligned negative dielectric aniostropy achiral nema...

The polarization properties of light scattered in a lateral direction from turbid media were studied. Polarization modulation and synchronous detection were used to measure, and Mueller calculus to model and derive, the degrees of surviving linear and circular polarization and the optical rotation induced by turbid samples. Polystyrene microspheres were used as scatterers in water solutions con...
