The color of colloidal dispersions of gold particles in a fluid, typically water, varies from red to
blue, depending upon the shape and size of particles. The color and optical properties of …

Charges on biological polymers in physiologically relevant solution conditions are strongly
screened by water and salt solutions containing counter-ions. However, the entropy of these …

Liquid crystals are partially ordered systems without a rigid, long-range structure. The study
of these materials covers a wide area: chemical structure, physical properties and technical …

We propose coating spherical particles or droplets with anisotropic nanosized objects to
allow micron-scale colloids to link or functionalize with a 4-fold valence, similar to the sp3 …

On the basis of a simple functional scaling, we have constructed the direct generalization of
the Carnahan–Starling equation for the free energy of a hard sphere fluid to a nematic liquid …

It is shown that the effect of electrostatic interactions on the liquid crystal phase transition in
solutions of rodlike polyelectrolytes can be characterized by two parameters, one describing …

To swim, a bacterium pushes against the fluid within which it is immersed, generating fluid
flow that dies off on a length scale comparable to the size of the bacterium. However, in …

Current understanding of different phases as well as the phase transitions between them
has only been achieved following recent theoretical advances on the effects of …

Tactoids are droplets of a nematic phase that under suitable conditions form in dispersions
of elongated colloidal particles. We theoretically study the shape and the director-field …

We report on the optical properties of the nematic (N) phase formed by lyotropic chromonic
liquid crystals (LCLCs) in well aligned planar samples. LCLCs belong to a broad class of …
