  • Publication number: 20240122918
    Abstract: A drug delivery device comprising: a first layer comprising a first coaxially electrospun nanofiber membrane; a second layer comprising a second coaxially electrospun nanofiber membrane; a first therapeutic agent integrated into the first coaxially electrospun nanofiber membrane; and a second therapeutic agent integrated into the second coaxially electrospun nanofiber membrane. The second therapeutic agent is different from the first therapeutic agent.

  • Publication number: 20210123174
    Abstract: A composite comprising electrospun inorganic fibers and nanoparticles. The composite may carry a reagent, for example an oxidant. The composite may be formed by electro spinning a composition of a precursor material and nanoparticles to form a precursor composite followed by conversion of precursor fibers of the precursor composite to the inorganic fibers. The composite carrying a reagent may be used to absorb ethylene gas.

  • Publication number: 20070221484
    Abstract: Electronic devices (10, 30, 50) utilizing electrically-controlled liquid components to accomplish device switching. Electric fields are used in a device structure to manipulate the position and/or geometrical shape of a conductive fluid or liquid (60, 24) using electrowetting. This manipulation regulates the flow of current between electrodes of the device structure, such as the source and drain regions (16, 20) of a transistor construction, by bridging a non-conductive channel (15) separating the electrodes (16, 20) so that the electrodes (16, 20) are electrically coupled.

  • Publication number: 20070031097
    Abstract: A signage device comprising one or more light sources, a waveguide or arrangement of waveguides and photoluminescent features coupled thereto. In one embodiment, a waveguide is adapted to receive light of a first wavelength and the photoluminescent features are adapted to emit light of a second wavelength in response to receiving light of the first wavelength.

  • Publication number: 20060268395
    Abstract: Electroluminescent waveguide amplifier and methods for amplifying optical data signals in a fiber optical telecommunications system to achieve signal enhancement that compensates for losses incurred by attenuation, optical splitting, and routing through the optical communication system. The waveguide amplifier (30) includes an electroluminescent active layer (38) having a host medium doped with luminescent dopant atoms capable of amplifying a propagating optical data signal (45) by stimulated emission of photons (41). Confining and insulating cladding layers (36, 40) surround the active layer (38) and confine the propagating optical data signals (45) being amplified to the active layer (38) and cladding layers (36, 40).

  • Publication number: 20050123243
    Abstract: A light emissive display having a specular waveguide that propagates short wavelength light and photoluminescent features adjacent to the waveguide that fluoresce, for example, in visible red, green, blue, and mixed colors when selectively coupled with the short wavelength light. The photoluminescent layers emit light primarily and, therefore, efficiently in the direction of an observer only. This light emissive display may be utilized as a planar light source, as patterned information signage, or as a re-configurable information display containing intensity modulated pixels. The light emissive display may be enhanced optically such that only a small portion of ambient light is reflected from the display while preserving the majority of emitted display luminance.
