Materials can be prepared in a layer-by-layer fashion on a patterned first substrate and subsequently transferred to a second substrate. The transfer step can preserve the pattern of the first substrate, such that the second substrate will bear a pattern of the transferred material. The material can be an electrostatic multilayer including a light absorbing dye, such as a J-aggregating cyanine dye.

Absorbing film

An optical fiber including a surface including a non-covalent multilayer including a light-absorbing material can be used to develop fluorescence microscopy with a lateral resolution of about 5 nm and possibly lower. The non-covalent multilayer can be a highly absorptive thin film, for example a film based on J-aggregates, which can be used with conventional Near-Field Scanning Optical Microscopy.

High resolution near field scanning optical microscopy

An optical structure can include a nanocrystal on a surface of an optical waveguide in a manner to couple the nanocrystal to the optical field of light propagating through the optical waveguide to generate an emission from the nanocrystal.

Optical structures including nanocrystals

A critically coupled optical resonator absorbs greater than 95% of incident light of the critical wavelength with an absorber layer less than 10 nm thick.

Light-absorbing structure and methods of making

A high oscillator strength thin film has an absorption constant greater than or equal to 10cm.

A light emitting device includes an optical cavity in resonance with an optical transition of a material disposed in the cavity. The device can form an exciton-polariton state.

Light emitting device

A plastic jacket that is used for repairing underwater or on ground support piles that have corroded by the wave action at the water line, by a tidal zone or natural salty air corrosion, respectively. The jacket consists of a cylindrical wall having annular corrugations on its exterior surface. The cylindrical wall has a longitudinal cut along its length to exhibit two opposing edges. A seal is placed between the opposing edges. Opposite from the longitudinal cut there is a V-shaped through the corrugations to the cylindrical wall to create a living hinge in the plastic material of the wall. Banding is provided to pull the opposing edges into a tight relationship and trapping the seal there between. The V-shaped cuts enable the jacket to be opened and placed around a damaged pile in spite of the corrugations which prevent such an opening. It is preferred that the material of the jacket be made of a transparent material. This way, when the any flaws, such as voids, develop within the poured concrete they can be observed through the transparent material and can be eliminated or corrected immediately.

Support pile repair jacket form

The invention relates to a plastic jacket that is used for repairing underwater piles that have been corroded by the wave action at the waterline or by a tidal zone. The jacket consists of a cylindrical wall having annular corrugations on its exterior surface. The cylindrical wall has a longitudinal cut along its length to exhibit two opposing edges. A seal is placed between the opposing edges. Opposite from the longitudinal cut there is a V-shaped cut through the corrugations to the cylindrical wall to create a living hinge in the plastic material of the wall. Banding is provided to pull the opposing edges into a tight relationship and trapping the seal there between. The V-shaped cuts enable the jacket to be opened and placed around a damaged pile in spite of the corrugations which would prevent such an opening.
