Abstract: A UV light sensor includes a first substrate, a second substrate, and a cholesteric liquid crystal layer between the first and second substrates. The liquid crystal layer contains a passive, achiral nematic liquid crystal host; a passive chiral compound; and a photoresponsive chiral dopant. At least one of the substrates is transparent to UV light and the liquid crystal layer is configured to exhibit a color change dependent upon UV light exposure.

Abstract: The invention relates to systems and methods for observing living cells or organisms, wherein the systems and methods utilize a microscopy system having an illumination source and an objective lens. A specimen including a predetermined amount of a liquid medium and a predetermined amount of an extracellular strongly absorbing dye is positioned for observation using the microscopy system. The illumination of the specimen correlates to the spectral region around the peak of the dye absorbance for the dye used in the system, such that live cells and organisms appear in contrast over a dark background for observation.

Abstract: A method of patterning an electrically-conductive film is performed by providing a flexible substrate that carries the electrically-conductive film thereon to form a combined layer. The combined layer is then bent about a radius of curvature, so as to impart a stress on the brittle conductive film along the axis of curvature of the curved surface. The application of the stress to the conductive film results in the formation of crack lines that are substantially perpendicular to the direction to which the substrate and conductive film are bent. The crack lines serve to define and electrically isolate conductive sections therebetween that can be utilized as electrodes and address lines in electronic devices.

Abstract: This disclosure outlines a new method of modifying the properties of existing liquid crystals by doping them with ferroelectric micro- and nanoparticles. We show that this approach, in contrast to the traditional time consuming and expensive chemical synthetic methods, enriches and enhances the electro-optical performance of many liquid crystal materials. We demonstrate that by changing the concentration and type of ferroelectric particles the physical properties of the nematic, smectic, and cholesteric liquid crystal materials can be changed, including the dielectric constants, the birefringence, the phase transition temperatures, and even the order parameter. We also demonstrate the performance of these new materials in various devices, including displays, light modulators, and beam steering devices.

Abstract: A method for fast switching a dual frequency (Fig. 3) liquid crystal cell is disclosed. The liquid crystal cell has opposed substrates (12) with a dual frequency liquid crystal material (18) disposed therebetween. Each substrate has an electrode that is connected to a power supply (20) that is able to apply different voltage magnitudes at different frequencies. And each substrate (12) has an alignment layer that imparts a high pretilt angle to the liquid crystal material, wherein no application of voltage results in the material exhibiting an initial state. A transition driving pulse (104) of a first magnitude is applied to the material at a first frequency to accelerate a transition into a first state from the initial state. A holding pulse (102) of a second magnitude is applied to the material at the first frequency to maintain the first state, wherein the second magnitude is less than the first magnitude.
