Topologically reconfigurable nematic emulsions
Saikat Das, Seyed Reza Seyednejad, Simon Čopar, Surajit Dhara
Izvirni znanstveni članek
Oznake: tekoči kristali;nematske emulzije;topološki defekti;liquid crystals;nematic emulsions;topological defects;
In emulsions of multicomponent fluids, the dispersed phase forms tiny droplets in the continuous phase. In situ control and manipulation to achieve diversity in emulsion droplets for emerging applications is challenging. In a liquid crystal-based emulsion, the surface anchoring of the molecules at t ...

Electrically reconfigurable topology in three-phase nematic emulsions
Saikat Das, Seyed Reza Seyednejad, Simon Čopar, Surajit Dhara
Izvirni znanstveni članek
Oznake: tekoči kristali;nematske emulzije;defekti;topologija;liquid crystals;nematic emulsions;defects;topology;
We report a nematic emulsion in which silicone oil droplets dispersed in a nematic liquid crystal induce conic anchoring and spontaneously stabilize elastic hexadecapolar distortions. Exploiting the symmetry and angular profile of these droplets, we develop a controlled fusion strategy to assemble t ...

Quasistatic reorientation of ferromagnetic nematic colloids in a slowly rotating magnetic field
Pinaki Kundu, Peter Marinko, Darja Lisjak, Shivaraja Santhegudda Jayaramappa, Simon Čopar, Surajit Dhara
Izvirni znanstveni članek
Oznake: tekoči kristali;feromagnetni tekoči kristali;magneto-optični pojav;elastične deformacije;liquid crystals;ferromagnetic liquid crystals;magneto-optical effect;elastic deformations;
We report the development of ferromagnetic nematic colloids using a two-step protocol tailored for investigating emergent magnetoelastic phenomena. First, we prepared a ferromagnetic nematic liquid crystal by dispersing well-defined magnetic nanoparticles into a conventional nematic host, ensuring m ...
