In a cholesteric liquid crystal, the rod-like molecules present a helical arrangement in a
single direction. The pitch of the helix at equilibrium can be continuously changed by …

The tools of surface science have enabled a thorough understanding of the ordering of
liquid crystalline materials in contact with the surfaces of solids. This report moves beyond …

The ability to generate regular spatial arrangements of particles is an important
technological and fundamental aspect of colloidal science. We showed that colloidal …

The ordering of liquid crystals (LCs) is known to be influenced by surfaces and
contaminants. Here, we report that picogram per milliliter concentrations of endotoxin in …

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 …

A versatile sensing method based on monodisperse liquid crystal (LC) emulsion droplets
detects and distinguishes between different types of bacteria (Gram+ ve and− ve) and …

I started the work on liquid crystal colloids around the year 2000 as a continuation of our
experiments on forces between surfaces in liquid crystals. We were using the atomic force …

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 …

The key to high-level encryption and anti-counterfeiting techniques is the storage of multiple
levels of distinct information that can be individually and precisely addressed by certain …

We explore the structure of nuclei and topological defects in the first-order phase transition
between the nematic (N) and isotropic (I) phases in lyotropic chromonic liquid crystals …
