Cholesteric and screw-like nematic phases in systems of helical particles
Giorgio Cinacchi, Alberta Ferrarini, Achille Giacometti +1
Recent numerical simulations of hard helical particle systems unveiled the existence of a novel chiral nematic phase, termed screw-like, characterised by the helical organization o…
Theory and simulation studies of self-assembly of helical particle
Giorgio Cinacchi, Alberta Ferrarini, Elisa Frezza +2
This is the unedited authors' version of Chapter 3 appearing in the following book: Self-Assembly Systems: Theory and Simulations Ed. Li-Tang Yan John Wiley & Sons, Ltd, Chichester…
Chiral Self-Assembly of Helical Particles
Hima Bindu Kolli, Giorgio Cinacchi, Alberta Ferrarini +1
The shape of the building blocks plays a crucial role in directing self-assembly towards desired architectures. Out of the many different shapes, helix has a unique position. Helic…
Self-assembly of hard helices: a rich and unconventional polymorphism
Hima Bindu Kolli, Elisa Frezza, Giorgio Cinacchi +5
Hard helices can be regarded as a paradigmatic elementary model for a number of natural and synthetic soft matter systems, all featuring the helix as their basic structural unit: f…
Left or right cholesterics? A matter of helix handedness and curliness
Elisa Frezza, Alberta Ferrarini, Hima Bindu Kolli +2
We have investigated the relationship between the morphology of helical particles and the features of the cholesteric (N) phase that they form. Using an Onsager-like theory…
From rods to helices: evidence of a screw-like nematic phase
Hima Bindu Kolli, Elisa Frezza, Giorgio Cinacchi +3
Evidence of a special chiral nematic phase is provided using numerical simulation and Onsager theory for systems of hard helical particles. This phase appears at the high density e…
The isotropic-to-nematic phase transition in hard helices: theory and simulation
Elisa Frezza, Alberta Ferrarini, Hima Bindu Kolli +2
We investigate the isotropic-to-nematic phase transition in systems of hard helical particles, using Onsager theory and Monte Carlo computer simulations. Motivation of this work re…
From the double-stranded helix to the chiral nematic phase of B-DNA: a molecular model
F. Tombolato, A. Ferrarini
B-DNA solutions of suitable concentration form left-handed chiral nematic phases (cholesterics). Such phases have also been observed in solutions of other stiff or semiflexible chi…
