Abstract: Disclosed is liquid crystal paper and an erasing device that is not permanently connected to the liquid crystal paper. A sheet of liquid crystal paper includes flexible polymeric substrates. A polymer network or a spacer network, in which bistable cholesteric reflective liquid crystal material is dispersed, is disposed between two of the substrates. Optional alignment layers or optional electrically conductive layers sandwich the liquid crystal material therebetween. An optional layer of light absorbing material is disposed near one of the substrates. Application of pressure to an upper substrate changes a focal conic nonreflective texture of the liquid crystal material to a reflective planar texture. The erasing device applies a voltage or heat for erasing the paper by changing the reflective planar texture to the focal conic nonreflective texture.

Abstract: A stable dispersion and a process of preparing a stable dispersion of one or more sterols in an aqueous solution are disclosed. An oil component is used as a carrier and is mixed with the one or more sterols in suspension to facilitate dispersion of the sterol in the aqueous solution. The aqueous solution may be an alcoholic solution. Freezing the stable dispersion of one or more sterols in the aqueous solution provides for a ready-to-pour frozen slush beverage.
