Interaction and self-assembly of membrane-binding and membrane-excluding colloids embedded in lamellar phases
Ruben Zakine, Dasith de Silva Edirimuni, Doru Constantin +2
Within the framework of a discrete Gaussian model, we present analytical results for the interaction induced by a lamellar phase between small embedded colloids. We consider the tw…
Coupling between Inclusions and Membranes at the Nanoscale
Florent Bories, Doru Constantin, Paolo Galatola +1
The activity of cell membrane inclusions (such as ion channels) is influenced by the host lipid membrane, to which they are elastically coupled. This coupling concerns the hydropho…
Behavior of colloidal particles at an air/nematic liquid crystal interface
M. A. Gharbi, M. Nobili, M. In +4
We examine the behavior of spherical silica particles trapped at an air-nematic liquid crystal interface. When a strong normal anchoring is imposed, the beads spontaneously form va…
Modeling planar degenerate wetting and anchoring in nematic liquid crystals
Jean-Baptiste Fournier, Paolo Galatola
We propose a simple surface potential favoring the planar degenerate anchoring of nematic liquid crystals, i.e., the tendency of the molecules to align parallel to one another alon…
Interaction and flocculation of spherical colloids wetted by a surface-induced corona of paranematic order
Paolo Galatola, Jean-Baptiste Fournier, Holger Stark
Particles dispersed in a liquid crystal above the nematic-isotropic phase transition are wetted by a surface-induced corona of paranematic order. Such coronas give rise to pronounc…
Exact calculations of the paranematic interaction energy for colloidal dispersions in the isotropic phase of a nematogenic material
J. -B. Fournier, P. Galatola
In a recent paper [Phys. Rev. E 61, 2831 (2000)], Borstnik, Stark and Zumer have studied the stability of a colloidal dispersion of micron-sized spherical particles in the isotropi…
Anisotropic Capillary Interactions and Jamming of Colloidal Particles Trapped at a Liquid-Fluid Interface
J. -B. Fournier, P. Galatola
We determine the capillary attraction and equilibrium configurations of particles trapped at a liquid-fluid interface due to the pinning of their contact-line. We calculate analyti…
Analytical characterization of adhering vesicles
C. Tordeux, J. -B. Fournier, P. Galatola
We characterize vesicle adhesion onto homogeneous substrates by means of a perturbative expansion around the infinite adhesion limit, where curvature elasticity effects are absent.…
Nematic-Wetted Colloids in the Isotropic Phase: Pairwise Interaction, Biaxiality and Defects
P. Galatola, J. -B. Fournier
We calculate the interaction between two spherical colloidal particles embedded in the isotropic phase of a nematogenic liquid. The surface of the particles induces wetting nematic…
Coarse-grained surface energies and temperature-induced anchoring transitions in nematic liquid crystals
J. -B. Fournier, P. Galatola
We introduce a coarse-grained description of the surface energy of a nematic liquid crystal. The thermal fluctuations of the nematic director close to the surface renormalize at ma…
