Defect Spirograph: Dynamical Behavior of Defects in Spatially Patterned Active Nematics
Ali Mozaffari, Rui Zhang, Noe Atzin +1
Topological defects in active liquid crystals can be confined by introducing gradients of activity. Here, we examine the dynamical behavior of two defects confined by a sharp gradi…
Controlling placement of nonspherical (boomerang) colloids in nematic cells with photopatterned director
Chenhui Peng, Taras Turiv, Rui Zhang +5
Placing colloidal particles in predesigned sites represents a major challenge of the current state-of-the-art colloidal science. Nematic liquid crystals with spatially varying dire…
Long range polarization attraction between two different likely charged macroions
Rui Zhang, B. I. Shklovskii
It is known that in a water solution with multivalent counterions (Z-ions), two likely charged macroions can attract each other due to correlations of Z-ions adsorbed on their surf…
Phase diagram of solution of oppositely charged polyelectrolytes
Rui Zhang, B. I. Shklovskii
We study a solution of long polyanions (PA) with shorter polycations (PC) and focus on the role of Coulomb interaction. A good example is solutions of DNA and PC which are widely s…
