摘要： Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiO2 nanostructured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.

摘要： A volume holographic imaging system, apparatus, and/or method enables the projection of a two-dimensional (2D) slice of a four-dimensional (4D) probing object. A 4D probing source object is illuminated to emit or scatter an optical field. A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam having spectral information. A 4-f telecentric relay system includes a pupil filter on the relayed conjugate plane of the volume hologram and images the pupil of the volume hologram onto the front focal plane of the collector lens. A collector lens focuses the diffracted plane beam to a 2D slice of the 4D probing source object. The focused 2D slice is projected onto a 2D imaging plane. The holographic element may have multiple multiplexed holograms that are arranged to diffract light from the corresponding slice of the 4D probing source object.

摘要： One aspect of the invention relates to an ultrathin micro-electromechanical chemical sensing device which uses swelling or straining of a reactive organic material for sensing. In certain embodiments, the device comprises a contact on-off switch chemical sensor. For example, the device can comprises a small gap separating two electrodes, wherein the gap can be closed as a result of the swelling or stressing of an organic polymer coating on one or both sides of the gap. In certain embodiments, the swelling or stressing is due to the organic polymer reacting with a target analyte.

摘要： A switching system is disclosed for an optical signal. The switching system includes a first optical waveguide coupled to a first electrode, a second electrode, and a second optical waveguide. The second optical waveguide is coupled to a movable electrode. The movable electrode is supported by a support structure and is positioned with respect to the first and second electrodes so that the position of the movable electrode may be selectively placed in either a first closed state or a second open state defined by the first and second electrodes under application of a voltage with respect to one of the first and second electrodes. The first closed state provides that the first and second optical waveguides are sufficiently close to each other to provide optical coupling therebetween while the second open state provides that the first and second optical communication channels are not sufficiently close to each other to provide optical coupling therebetween, or provide some different amount of optical coupling than in the first closed state.
