Designing corrugated surfaces to guide colloidal self-assembly

Dinesh Kumar Sahu, Jude Ann Vishnu, Lisa Shafroth +3

The self-assembly of colloidal particles enables the creation of structured materials with programmable functionalities; however, controlling interaction specificity and aggregate…

Defect-polymorphism controlled electrophoretic propulsion of anisometric microparticles in a nematic liquid crystal

Devika V S, Dinesh Kumar Sahu, Ravi Kumar Pujala +1

Nontrivial shape of colloidal particles create complex elastic distortions and topological defects in liquid crystals and play a key role in governing their electrophoretic propuls…

Electrophoresis of metal-dielectric Janus particles with dipolar director symmetry in nematic liquid crystals

Dinesh Kumar Sahu, Surajit Dhara

We study electrophoretic mobility of metal-dielectric Janus particles with dipolar director profile in two nematic liquid crystals (LCs) having same (positive) conductivity anisotr…

Electric field driven controllable motility of metal-dielectric Janus particles with boojum defects in a nematic liquid crystal

Dinesh Kumar Sahu, Surajit Dhara

In a sharp contrast to the response of silica particles we show that the metal-dielectric Janus particles with boojum defects in a nematic liquid crystal are self-propelled under t…

A novel method for measuring electric field induced dipole moments of metal-dielectric Janus particles in nematic liquid crystals

Dinesh Kumar Sahu, Surajit Dhara

Janus particles are special types of nano or micro particles possessing at least two surfaces with distinct physical or chemical properties. The most studied Janus particles are th…

Omnidirectional transport and navigation of Janus particles through a nematic liquid crystal film

Dinesh Kumar Sahu, Swapnil Kole, Sriram Ramaswamy +1

We create controllable active particles in the form of metal-dielectric Janus colloids which acquire motility through a nematic liquid crystal film by transducing the energy of an…
