Nontrivial electrophoresis of silica micro and nanorods in a nematic liquid crystal
Muhammed Rasi M, Archana S, Ravi Kumar Pujala +1
We study DC and AC electrophoresis of silica micro and nanorods in a thin film of a nematic liquid crystal. These particles induce virtual topological defects and also demonstrate…
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…
Interactions of charged microrods in chiral nematic liquid crystals
Muhammed Rasi M, Ravi Kumar Pujala, Sathyanarayana Paladugu +1
We study the pair interaction of charged silica microrods in chiral nematic liquid crystals and show that the microrods with homeotropic surface anchoring form a bound state due to…
Microrheology to Probe Smectic Clusters in Bent-core Nematic Liquid Crystals
Sathyanarayana Paladugu, Supreet Kaur, Golam Mohiuddin +3
Many bent-core nematic liquid crystals exhibit unusual physical properties due to the presence of smectic clusters, known as "cybotactic" clusters in the nematic phase. Effect of t…
Orientation Dependent Interaction and Self-assembly of Cubic Magnetic Colloids in a Nematic Liquid Crystal
Devika V S, Ravi Kumar Pujala, Surajit Dhara
Spherical microparticles dispersed in nematic liquid crystals have been extensively investigated in the past years. Here, we report experimental studies on the elastic deformation,…
Microstructure and Aging Dynamics of Fluorescent Nanoclay Co-gels of Laponite and Montmorillonite
Ravi Kumar Pujala, H. B. Bohidar
The phenomenon of aging in soft matter systems is an intriguing and interesting. In his study we investigate the microstructure and aging dynamics of fluorescent nanoclay gels form…
Spontaneous evolution of self-assembled phases from anisotropic colloidal dispersions
Ravi Kumar Pujala, Nidhi Joshi, H. B. Bohidar
We investigate the spontaneous evolution of various self-assembled phase states from a homogeneous aqueous dispersion of high-aspect ratio Montmorillonite (Na Cloisite) nanoclay pl…
