Oriented Gold Nanorods and Gold Nanorod Chains within Smectic Liquid Crystal Topological Defects

Topological Defects in Nematic and Smectic Liquid Crystals

TOPOLOGICAL DEFECTS IN NEMATIC AND SMECTIC LIQUID CRYSTALS Bryan Gin-ge Chen Randall D. Kamien Liquid crystals are materials with interesting symmetries and order, and their science and applications are a playground of geometry and elasticity. I discuss various aspects of the study of topology and topological defects in liquid crystalline systems beyond the traditional calculation of homotopy g...

Electrically Reconfigurable and Thermally Sensitive Optical Properties of Gold Nanorods Dispersed Liquid Crystal Blue Phase

Morphogenesis of liquid crystal topological defects during the nematic-smectic A phase transition

The liquid crystalline phases of matter each possess distinct types of defects that have drawn great interest in areas such as topology, self-assembly and material micropatterning. However, relatively little is known about how defects in one liquid crystalline phase arise from defects or deformations in another phase upon crossing a phase transition. Here, we directly examine defects in the in ...

Aqueous-organic phase transfer of gold nanoparticles and gold nanorods using an ionic liquid.

The water-immiscible ionic liquid, [C4MIM][PF6], is a solvent medium that allows complete transfer of gold nanoparticles from an aqueous phase into an organic phase. Both spherical and rod-shaped gold nanoparticles are efficiently transferred from an aqueous solution into the organic phase without requiring the use of thiols. The sizes and shapes of the gold nanoparticles were preserved during ...
