From Bend to Splay Dominated Elasticity in Nematics
Autor: Davide Revignas, Alberta Ferrarini
Publikováno v: Crystals, Vol 11, Iss 7, p 831 (2021)
In the past decade, much evidence has been provided for an unusually low cost for bend deformations in the nematic phase of bent-core mesogens and bimesogens (liquid crystal dimers) having a bent shape on average. Recently, an analogous effect was ob

The interplay of configuration and conformation in helical perylenequinones: Insights from chirality induction in liquid crystals and calculations
Autor: Elisa Frezza, Silvia Pieraccini, Stefania Mazzini, Alberta Ferrarini, Gian Piero Spada
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 8, Iss 1, Pp 155-163 (2012)
The chirality transfer in liquid crystals induced by two helical perylenequinones (namely, the natural compounds cercosporin and phleichrome) was investigated by integrating measurements of helical twisting power with a conformational analysis by DFT

Chiral amplification in a cyanobiphenyl nematic liquid crystal doped with helicene-like derivatives
Autor: Alberta Ferrarini, Silvia Pieraccini, Stefano Masiero, Gian Piero Spada
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 5, Iss 1, p 50 (2009)
The addition of a chiral non-racemic dopant to a nematic liquid crystal (LC) has the effect of transferring the molecular chirality to the phase organization and a chiral nematic phase is formed. This molecular chirality amplification in the LC provi

Exploring the behaviour of the twist-bend nematic phase using NMR with a variety of spin probes
Autor: Cristina Greco, Geoffrey R. Luckhurst, Herbert Zimmermann, Bakir A. Timimi, Alberta Ferrarini
Publikováno v: Liquid Crystals
Here we discuss the use of deuteriated probe molecules in NMR studies of the nematic (N) and twist-bend nematic (NTB) phases formed by the generic liquid crystal dimer CB7CB. The key properties of three probes dissolved in the NTB phase investigated

The Journal of Physical Chemistry Letters
The biological light-harvesting process offers an unlimited source of inspiration. The high level of control, adaptation capability, and efficiency challenge humankind to create artificial biomimicking nanoarchitectures with the same performances to

Helical Inclusions in Phospholipid Membranes: Lipid Adaptation and Chiral Order
Autor: Martina Pannuzzo, Domenica Raciti, Antonio Raudino, Alberta Ferrarini, Beata Szała
Publikováno v: The Journal of Physical Chemistry Letters. 10:5629-5633
The lipid bilayer is a flexible matrix that is able to adapt in response to the perturbation induced by inclusions, such as peptides and proteins. Here we use molecular dynamics simulations with a coarse-grained model to investigate the effect of a h

Thermo-orientation in fluids of arbitrarily shaped particles
Autor: Alberta Ferrarini, Andrea Gardin
Publikováno v: Physical Chemistry Chemical Physics. 21:104-113
Recent nonequilibrium Molecular Dynamics (NEMD) simulations revealed preferential orientation, induced by a temperature gradient, in fluids of uncharged dumbbell-like particles. The magnitude of this phenomenon, called thermo-orientation, was found t

Interplay of Particle Morphology and Director Distortions in Nematic Fluids
Autor: Davide Revignas, Alberta Ferrarini
Publikováno v: Physical review letters. 125(26)
The existing microscopic theories for elasticity of nematics are challenged by recent findings on systems, whether bent molecules or semiflexible polymers, which do not comply with the model of rigid rodlike particles. Here, we propose an extension o
