An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...

In this paper, we fabricated the inverse four domain twisted nematic liquid crystal cell using stacked vertical alignment layer on planar alignment layer for strong azimuthal anchoring energy. That makes possible twist structures under applied voltage without chiral-dopant, as a result, high transmittance and wide viewing angle could be revealed.

Chromonic liquid crystals are formed by molecules that spontaneously assemble into anisotropic structures in water. The ordering unit is therefore a molecular assembly instead of a molecule as in thermotropic liquid crystals. Although it has been known for a long time that certain dyes, drugs, and nucleic acids form chromonic liquid crystals, only recently has enough knowledge been gained on ho...

An achiral nematic liquid crystal was doped with a small quantity of carbon nanotubes, and the mixture was found to induce an average mechanical twist over macroscopic dimensions. The nanotube-induced chiral pitch length P was determined as a function of average nanotube concentration by measuring the radii of curvature of reverse twist disclination lines in 90° twisted nematic cells. The resul...

Chirality is ubiquitous in nature and plays crucial roles in biology, medicine, physics and materials science 1–5. Understanding and controlling chirality is therefore an important research challenge with broad implications in fundamental and applied sciences. Unlike other classes of chiral colloids, such as nanocellulose or filamentous viruses, amyloid fibrils form nematic phases but appear to...

Various experimental and theoretical studies demonstrate that complex stimulus-responsive out-of-plane distortions such as twist of different chirality, emergence of cones, simple and anticlastic bending can be engineered and pre-programmed in a liquid crystalline rubbery material given a well-controlled director microstructure. Via 3-d finite element simulation studies, we demonstrate director...
