A perspective on the Langmuir adsorption model applied to molecular liquid crystals containing ions and nanoparticles

Frontiers in Soft Matter, 2022
Electrical properties of molecular liquid crystals doped with nanomaterials have been extensively studied over the past two decades. In general, nanoparticles in liquid crystals can play a dual role acting as either ion capturing agents or ion generating

ON LIQUID CRYSTALS AND LIQUID CRYSTAL DISPERSIONS

Annals of the Academy of Romanian Scientists Series on Physics and Chemistry, 2022
This short review paper presents some important aspects ofliquid crystal and liquid crystal composites. Preparation methods ofpolymer dispersed liquid crystalfdms (PDLC), the obtained structure and their main application as light valve are shown. In the last decade, the field has experienced a sharp revitalization, due to nanodoping, which results in ...

Chirality amplification by desymmetrization of chiral ligand-capped nanoparticles to nanorods quantified in soft condensed matter

Nature Communications, 2018
The mechanisms by which molecular chirality is amplified through space and across length scales is of great interest. Here the authors show how gold nanorods covered in chiral dopants are more efficient in transducing chiral information compared to other
