Journal ArticleDOI
Self-Organization into 2D and 3D Superlattices of Nanosized Particles Differing by Their Size
TL;DR: In this article, the formation of self-assemblies of nanoparticles strongly depends on the preparation conditions of the samples, and it is also shown that in the aggregates the particles are highly organized and form pseudocrystals with a face-centered cubic structure for various particles sizes.
Journal ArticleDOI
Ruthenium Nanoparticles: Size, Shape, and Self-Assemblies
Guillaume Viau,Roberta Brayner,L. Poul,Nassira Chakroune,Emmanuelle Lacaze,F. Fiévet-Vincent,Fernand Fiévet +6 more
TL;DR: In this paper, Roditty et al. used the dodecane thiol concentration in the colloidal solution to determine, within the particle monolayer, the formation of either columnar units made up of edgewise stacked platelets or a hexagonal network with a mean distance between the particles of 2 nm.
Journal ArticleDOI
Ordering nano- and microparticles assemblies with liquid crystals
TL;DR: In this article, the authors present an overview on particles/LC systems, the size of the dispersed particles being larger than the typical LC length, and discuss the evolution of the relevant interactions between nanoparticles (NPs) dispersed in liquid crystals when their size decreases from micrometers to nanometers.
Journal ArticleDOI
Linear self-assembly of nanoparticles within liquid crystal defect arrays.
Delphine Coursault,Johan Grand,Bruno Zappone,Habib Ayeb,Georges Lévi,Nordin Félidj,Emmanuelle Lacaze +6 more
TL;DR: In the presence of oriented smectic liquid crystal defects, hybrid systems of nanoparticle/liquid crystals form straight chains of nanoparticles of length longer than tens of micrometers and width equal to one single nanoparticle, highlighting the control of optical absorption by light polarization monitored by gold nanoparticle concentration.
Journal ArticleDOI
Controlling chirality with helix inversion in cholesteric liquid crystals
TL;DR: In this paper, the authors provide an overview on recent advances in controlling and understanding helix inversion in cholesteric liquid crystals, and predict which systems display inversion also remains a challenge because of the subtle balance of contributions underlying this phenomenon.
