摘要:
A method for producing a condenser for a thermal power plant is provided. First, the production method includes fitting a condenser tube in a carrier for a condenser tube bundle of the condenser. Then, the fitted condenser tube is coated with a hydrophobic coating. Coating the fitted condenser tube includes positioning a spray mechanism on the carrier, spraying on the hydrophobic coating using a spray mechanism, and moving the spray mechanism during spraying at a uniform rate. In another aspect, a device is provided. Also, a condenser is provided in an aspect.

A system and method is provided for using sunlight to convert an atmospheric gas to an output product and capture that output product. A photocatalytic element is encapsulated within a chamber of a photocatalytic panel in which the chamber is light transmissive, and is substantially permeable to the atmospheric gas and substantially impermeable to the output product. Water may be provided to the photocatalytic element to react with the atmospheric gas. A system is provided for withdrawing the output product for storage.

A substrate for a field emitter suitable for use in computed tomography has a coating with carbon hybrid structures based on the allotropes graphite, graphene and nanotubes. The field emitters are based on graphite layer structures. A substrate for field emitters is achieved for the first time that uses “graphite combs” protruding and aligned essentially perpendicular to the substrate as well as hybrid materials from these combs with CNTs supported between them on a conductive substrate.

A device for detecting at least one substance of a fluid includes at least one piezo-acoustic resonator with at least one piezo layer, an electrode arranged on the piezo-electric layer, at least one other electrode arranged on the piezo-electric layer and a surface section used for sorption of the substance of the fluid. The piezo-electric layer, the electrodes and the surface section are disposed in such a way that electric control of the electrodes leads to an oscillation of the resonator at a resonance frequency which depends upon the amount of the substance which is sorbed on the surface section. The thickness of the pioelectric layer is in the region of 0.5 to 20 μm and the resonance frequency of the oscillation ranges from 500 MHz to 2 GHz. The device is a mass sensor with a piezo-acoustic high-frequency thin film resonator.

A hydrophilic immobilization layer for biosensors is made of a radically cross-linkable hydrogel based on polyacraylamide. The starting composition includes acrylamide, cross-linkers, radical initiator(s), at least one comonomer having reactive linker groups and optionally may include softeners. Alternatively, the inventive layer may be of a photostructured hydrogel based on polyacrylamide. The starting composition includes acrylamide, cross-linkers, photoinitiators, at least one film former, at least one comonomer having reactive linker groups and optionally may include softeners.

In a fibrous planar structure in which fibers are embedded in a matrix, an increase in mechanical resistance is achieved by improving the adhesion between the fiber and the matrix.
摘要:
A stencil body of a screen stencil body has a surface coating made up of hydrocarbon-based, organic precursor molecules. A plasma-coating method is used to coat the screen stencil, wherein a layer of hydrocarbon-based, organic precursor molecules is deposited on the surface of the stencil body of the screen stencil.

摘要:
A substrate for field emitters uses carbon nanotubes (CNTs) on a conductive substrate, the CNTs being erected essentially perpendicular to the substrate and aligned. In a method to transfer a CNT forest from a first substrate to a second substrate, the second substrate is coated with adhesive and the peaks (tips) of the CNTs on the first substrate are embedded in the uncurred adhesive on the second substrate. After the adhesive cures, the CNTs are removed from the first substrate with the peaks anchored in the cured adhesive on the second substrate.
