We make hard-sphere colloidal crystals from polymethyl methacrylate spheres suspended in organic solvents at high volume fractions. The samples are crystallized between two glass plates separated by 10-\ensuremath{\mu}m spacer beads. We study the opt

We report the results of measurements of the spontaneous emission lifetime of a ${\mathrm{Eu}}^{3+}$ complex in the presence of a nearby metal surface. The excited-state lifetime of the ions are measured as a function of their separation from both pl

We investigate the spontaneous emission rate of ${\mathrm{Eu}}^{3+}$ ions in an asymmetric microcavity. The cavity consists of a thin dielectric layer bounded on one side by silver and on the other by air. Samples were constructed using the Langmuir-

We have experimentally determined how the spontaneous emission rate of Eu{sup 3+} ions depends upon both the distance from, and thickness of, a silver film. We show that as the silver film thickness is reduced ({lt} 100 nm) the well established influ

A comparative modeling and experimental study of the zenithal bistable liquid crystal device is presented. A dynamic Landau de Gennes theory of nematic liquid crystals is solved numerically to model the electric field induced latching of the device a

A study of the degradation kinetics of gemcitabine hydrochloride (2'-deoxy-2',2'-difluorocytidine) in aqueous solution at pH 3.2 was conducted. The degradation of gemcitabine followed pseudo first-order kinetics, and rate constants were determined at

Zenithal Bistable Devices use a deep homeotropic grating as one of the alignment layers to induce two stable surface pre-tilts. Attributes of the display such as operating voltage, temperature range, and optical properties depend on the shape and anc

Large-area face-centred cubic photonic crystals are fabricated by the two-dimensional shear-alignment of stabilised 720 nm diameter PMMA spheres dispersed in an epoxy resin. The resulting crystal is made permanent by exposure to UV light, thus solidi
