A superhydrophobic asphalt and a method of its preparation. The superhydrophobic asphalt contains an asphalt layer containing a polymer modified asphalt, preferably a radial SBS modified asphalt, and a polypropylene layer. The polypropylene layer comprises granules of polypropylene thermally fused to the asphalt layer. The superhydrophobic asphalt has a water contact angle of 145 to 170°, above the classification threshold for superhydrophobicity. The method of preparing the superhydrophobic asphalt involves distributing polypropylene granules over the surface of a polymer modified asphalt and curing below the melting temperature of the polypropylene. The asphalt may find use in waterproofing applications such as roofing.

In one embodiment, a bond coating on a surface of a ceramic component is generally provided with the bond coating including such a composition, with the silicon-containing material is silicon metal.

A member for an apparatus for manufacturing a semiconductor single crystal having long product life and a tantalum carbide coated carbon material are provided. The tantalum carbide coated carbon material according to the present invention is a tantalum carbide coated carbon material in which at least a part of a surface of a carbon base material is coated with a tantalum carbide coated film containing tantalum carbide as a main component, in which in the tantalum carbide coated film, an intensity of an X-ray diffraction line corresponding to a plane with respect to an out-of-plane direction is larger than intensities of X-ray diffraction lines corresponding to other crystal planes, and the intensity ratio is 60% or more with respect to a sum of intensities of X-ray diffraction lines corresponding to all crystal planes.

Embodiments of the present disclosure relate to methods for controlling etch depth by providing localized heating across a substrate. The method for controlling temperatures across the substrate can include individually controlling a plurality of heating pixels disposed in a dielectric body of a substrate support assembly. The plurality of heating pixels provide temperature distributions on a first surface of the substrate disposed on a support surface of the dielectric body. The temperature distributions correspond to a plurality of portions of at least one grating on a second surface of the substrate to be exposed to an ion beam. Additionally, the temperatures can be controlled by individually controlling light emitting diodes (LEDs) of LED arrays. The substrate is exposed to the ion beam to form a plurality of fins on the at least one grating. The at least one grating has a distribution of depths corresponding to the temperature distributions.

Post-construction materials, including concrete, containing water insoluble polymers are disclosed herein. The water insoluble polymers are formed beneath the surface of the post-construction material using a first composition comprising a blend of fatty acid salts and a second composition comprising alkaline earth metal halides or alkaline earth metal carbonates.

The present invention relates to coloured fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides coloured fiber cement products, which fiber cement products are coloured in the mass, and at least comprise on at least part of their outer surface one or more cured layers of a coating composition, which composition at least comprises a binder and a pigment and/or a filler and is characterized by a pigment volume concentration (PVC) of between about 1% and about 20%. The present invention further provides processes for producing these coloured fiber cement products. Finally, the present invention provides uses of the coloured fiber cement products as building materials. In particular embodiments, the fiber cement products produced by the processes of the present invention can be used to provide an outer surface to walls, both internal as well as external, a building or construction, e.g. as fagade plate, siding, etc.

A method and system to dry crack-free and high strength skin including an inorganic binder of an average particle size (D.sub.50) in a range between 10 nm and 700 nm on a porous ceramic body. The method includes supporting the honeycomb body on an end face such that axial channels and outer periphery are substantially vertical. A gas is flowed past the honeycomb body substantially parallel to the axial channel direction, substantially equally around the outer periphery of the skin, to uniformly dry the skin to form a partially dried skin under mild conditions. Then the partially dried skin may be dried more severely resulting in rapidly dried crack-free and high strength skin.

Provided is a SiC-coated carbon composite material including a graphite base material and a CVD-SiC coating covering the graphite base material. A porosity of a core part of the graphite base material is 12 to 20%, and a SiC-infiltrated layer extending from the CVD-SiC coating is included in a periphery of the core part of the graphite base material. The SiC-infiltrated layer is constituted of a plurality of regions arranged such that Si content becomes smaller stepwise in an order from a first surface on the CVD-SiC coating side toward a second surface on the graphite base material side.

An article comprises a body and a conformal protective layer on at least one surface of the body. The conformal protective layer is a plasma resistant rare earth oxide film having a thickness of less than 1000 μm, wherein the plasma resistant rare earth oxide film is selected from a group consisting of an Er—Y composition, an Er—Al—Y composition, an Er—Y—Zr composition, and an Er—Al composition.
