A sliding member includes a metallic substrate, a porous layer formed on a surface of the metallic substrate, and a sliding layer that covers the porous layer. The porous layer is made of a metal itself or an alloy composition. The sliding layer is made of a lead-free resin composition. The resin composition contains an essential additive, optionally an optional additive, and a fluororesin. The essential additive is any one of a combination of a zinc compound and a carbon fiber, a combination of a zinc compound and an iron oxide, and a combination of a zinc compound, a carbon fiber and an iron oxide. A total content of the essential additive and the optional additive is 10 vol % or more and 35 vol % or less in the resin composition.

A coating composition for a substrate includes a polymer binder, one or more hydrophobic silicon dioxide compositions, and one or more UV protection agents. The polymer binder can include a fluoropolymer or an epoxy polymer resin. The coating composition can also include molybdenum disulfide.

Examples herein include prosthetic valves, valve leaflets and related methods. In an example, a prosthetic valve is included having a plurality of leaflets. The leaflets can each have a root portion and an edge portion substantially opposite the root portion and movable relative to the root portion. The leaflets can include a fibrous matrix including polymeric fibers having an average diameter of about 10 nanometers to about 10 micrometers. A coating can surround the polymeric fibers within the fibrous matrix. The coating can have a thickness of about 3 to about 30 nanometers. The coating can be formed of a material selected from the group consisting of a metal oxide, a nitride, a carbide, a sulfide, or fluoride. In an example, a method of making a valve is included. Other examples are also included herein.

Synthesis, fabrication, and application of nanocomposite polymers in different form (as membrane/filter coatings, as beads, or as porous sponges) for the removal of microorganisms, heavy metals, organic, and inorganic chemicals from different contaminated water sources.

The present invention relates to a composition formed of a hot melt adhesive having a colour-forming compound admixed therein. The invention further relates to a substrate or multi-layer substrate construction having the composition applied thereon or therein, and methods of forming colour and/or an image on and/or within the substrate or multi-layer substrate construction using said composition.

An antimony-free adhesive package useful for making an insulation facing material includes a halogenated latex adhesive, a flame/smoke suppressant such as aluminum trihydrate, an intumescent such as aluminum polyphosphate, melamine powder, a melamine cyanurate, a mold and mildew inhibitor, an optional dispersant, an optional water holding agent, and optionally between 3% and 10% of a zinc molybdate/magnesium silicate complex and between 3% and 10% of a zinc phosphate/zinc oxide complex. Insulation facing material made with the adhesive package has a flame spread value that does not exceed 25, and a smoke developed value that does not exceed 50, and meets the applicable standards for operating temperature, anti-corrosiveness, corrosion, puncture resistance, water vapor transmission, water vapor sorption, shrinkage, microbial growth resistance, and water immersion bond integrity. The facing stock may be used to face insulation products such as rolls, batts, boards or molds of fiberglass or mineral wool insulation.

The invention relates to a method for producing an antimicrobially effective composite material (10), in which at least one molybdenum and/or tungsten containing inorganic compound is bound to at least one further material. Furthermore, the invention relates to an antimicrobially effective composite material (10), which includes at least one molybdenum and/or tungsten containing compound, which is bound to at least one further material.

A chemical mechanical polishing (abbreviated as CMP) conditioner comprises a bottom substrate, an intermediate substrate and a diamond film The intermediate substrate is provided on the bottom substrate. The intermediate substrate comprises a hollow portion, an annular portion surrounding the hollow portion, and at least one projecting ring projecting out of the annular portion away from the bottom substrate. The projecting ring comprises a plurality of bumps arranged to be spaced apart from each other along an annulus region. The bumps are extended in a radial direction of the intermediate substrate. The diamond film is provided on the intermediate substrate. The diamond film is allowed for conforming to the bumps, so as to form a plurality of the abrasive projections.

Embodiments of an optical fiber ribbon cable are provided. The optical fiber ribbon cable includes a cable jacket having an interior surface defining a central bore, at least one buffer tube located in the central bore of the cable jacket, and at least one optical fiber ribbon disposed within the at least one buffer tube. The at least one optical fiber ribbon includes a plurality of optical fibers, a polymer matrix surrounding the plurality of optical fibers, and a low-smoke, flame retardant (LSFR) coating surrounding the polymer matrix. The LSFR coating includes from 25 to 65% by weight of an inorganic, halogen-free flame retardant filler dispersed in a curable acrylate medium. Further, the inorganic, halogen-free flame retardant filler includes particles having, on average, a maximum outer dimension of 5 microns.
