Abstract: Polymeric mixtures of a cholesterol material and a monomer are disclosed which can advantageously be utilized for the construction of temperature indicating devices. Each polymeric composition exhibits a color at temperatures below a fixed threshold temperature and then appears colorless at the threshold temperature. This characteristic permits safe, compact, accurate, fast responsive, disposable temperature indicating and warning devices to be made.

Abstract: Stable, macroscopic single-crystal chiral liquid crystal compositions are described. The compositions include a single-crystal chiral liquid crystal material on a patterned surface. The patterned surface seeds a particular crystallographic orientation at the substrate-liquid crystal interface. Also described are methods of forming the single-crystal chiral liquid crystal compositions.

Abstract: Liquid crystal-based devices for detecting chlorine in a sample and methods of using such devices to detect chlorine are disclosed. Such devices have a substrate surface that includes either metal cations or a metal that is in contact with a composition that includes a liquid crystal. When the device is contacted with a sample that contains chlorine, an observed change in the orientational ordering of the liquid crystal signals the presence of the chlorine. In the absence of chlorine, no change in orientational ordering occurs.

Abstract: A method is described for preparing a nanorods assembly. The method comprises providing a mixture comprising at least a liquid crystal and nanorods and depositing said mixture on the surface of at least substrate. The method further comprises aligning said nanorods with their long axis of the nanorods along a preferred direction on said substrate resulting in a nanorods and liquid crystal assembly, said aligning being performed by applying an external alternating current electrical field.
