Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

A state of matter in which molecules show a long-range orientational order and no positional
order is called a nematic liquid crystal. The best known and most widely used (for example …

Bio-mechanical hybrids are an emerging class of engineered composite soft materials with
the ability to move and reconfigure their structure and properties in response to external …

Controlling the growth morphology of fluid instabilities is challenging because of their self-
amplified and nonlinear growth. The viscous fingering instability, which arises when a less …

The organization of nanoparticles in constrained geometries is an area of fundamental and
practical importance. Spherical confinement of nanocolloids leads to new modes of packing …

Morphogenesis of living systems involves topological shape transformations which are
highly unusual in the inanimate world. Here, we demonstrate that a droplet of a nematic …

Elastic constants of splay K 11, twist K 22, and bend K 33 of nematic liquid crystals are often
assumed to be equal to each other in order to simplify the theoretical description of complex …

Using dynamic light scattering, we study orientational fluctuation modes in the nematic
phase of a self-assembled lyotropic chromonic liquid crystal (LCLC) disodium cromoglycate …

Achieving control and tunability of lyotropic materials has been a long-standing goal of liquid
crystal research. Here we show that the elasticity of a liquid crystal system consisting of a …

Confined liquid crystals (LC) provide a unique platform for technological applications and for
the study of LC properties, such as bulk elasticity, surface anchoring, and topological …
