Pattern-induced anchoring transitions in nematic liquid crystals
Oscar A. Rojas-Gomez, Jose M. Romero-Enrique, Nuno M. Silvestre +1
In this paper we revisit the problem of a nematic liquid crystal in contact with patterned substrates. The substrate is modelled as a periodic array of parallel infinite grooves of…
Nematic Films at Chemically Structured Surfaces
Nuno M. Silvestre, Margarida M. Telo da Gama, Mykola Tasinkevych
We investigate theoretically the morphology of a thin nematic film adsorbed at flat substrate patterned by stripes with alternating aligning properties, normal and tangential respe…
Nematic liquid crystals on sinusoidal channels: the zigzag instability
Nuno M. Silvestre, Jose M. Romero-Enrique, Margarida M. Telo da Gama
Substrates which are chemically or topographically patterned induce a variety of liquid crystal textures. The response of the liquid crystal to competing surface orientations, typi…
The effect of curvature on cholesteric doughnuts
Ana Fialho, Nelson R. Bernardino, Nuno M. Silvestre +1
The confinement of liquid crystals inside curved geometries leads to exotic structures, with applications ranging from bio-sensors to optical switches and privacy windows. Here we…
Nonequilibrium self-organization of colloidal particles on substrates: adsorption, relaxation, and annealing
N. A. M. Araújo, C. S. Dias, M. M. Telo da Gama
Colloidal particles are considered ideal building blocks to produce materials with enhanced physical properties. The state-of-the-art techniques for synthesizing these particles pr…
Percolation in binary and ternary mixtures of patchy colloids
Felix Seiferling, Daniel de las Heras, Margarida M. Telo da Gama
We investigate percolation in binary and ternary mixtures of patchy colloidal particles theoretically and using Monte Carlo simulations. Each particle has three identical patches,…
