Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.

A shingle includes a substrate having an asphalt coating on a top surface of the substrate and on a bottom surface of the substrate. A surface layer of granules is embedded in the asphalt on the top surface of the substrate. A backdust layer of particles is embedded in the asphalt on the bottom surface of the substrate. A sealant is disposed on the backdust. A hydrophobic material is applied to the sealant.

A method is described for the production of a manufactured article (20) constituted of an elastomeric polymer substrate, in selected zones of which there are deposits of particles of nanometric size of a metal or some other compound which create a region (24) of the polymeric element having desired electrical, biocompatibility and/or dielectric properties, and such that said properties are maintained even after numerous elastic deformations of the manufactured article; the invention also relates to functionalized elastomeric manufactured articles obtained by means of said method.

Microfabricated particles are dispersed throughout a matrix to create a composite. The microfabricated particles are engineered to a specific structure and composition to enhance the physical attributes of a composite material.

The present invention relates to a non-woven fabric made of inorganic fibers, which has a coating of at least two layers on one of both surfaces, wherein (i) the non-woven fabric made of inorganic fibers has a thickness of at least 0.2 mm, (ii) the first layer of the coating comprises particles, whose particle size is between 50 and 100 m, (iii) the second layer of the coating, which is applied onto the first layer, comprises particles, wherein more than 90% of the particles have a particle size of less than 20 m. The non-woven fabric made of inorganic fibers according to the invention, in particular glass non-woven fabrics, are in particular suitable for producing decorative coatings for floor coverings, ceiling coverings and wall coverings.

Provided are a kitchen appliance coated by a dot method including a primer coating layer formed on a surface of the kitchen appliance, and a dot layer formed in a dot shape on a surface of the primer coating layer by repetitive point spraying a coating solution of dot particles, wherein the dot particles are individually adhered to the primer coating layer by the point spraying to form a surface, the dot particles has an average diameter of 5 m to 10 mm when being adhered to the primer coating layer by the point spraying, an area ratio of the dot layer to the primer coating layer is in a range of 60% to 98%, the dot layer is spattered by a point spraying method in which the dot layer is formed by overlapping 0 to 20 layers of the dot particles, various colors of the dot layer are obtained by simultaneously or individually point spraying through a plurality of nozzles respectively including coating solutions of various colors, and a liquid component of the dot particles point sprayed in a form of a liquid is dried during drying to be separated into the individual dot particle to cause irregularities at an upper end portion of the dot layer in view of the entire dot layer, and a method of preparing the kitchen appliance.

The invention relates to boron nitride agglomerates, comprising lamellar, hexagonal boron nitride primary particles, which are agglomerated with one another with a preferred orientation, the agglomerates formed being flake-shaped.

The invention also relates to a method for producing said boron nitride agglomerates, characterized in that lamellar, hexagonal boron nitride primary particles are agglomerated in such a way that they line up with one another with a preferred orientation.

The flake-shaped agglomerates according to the invention are suitable as filler for polymers for making polymer-boron nitride composites and for hot pressing of boron nitride sintered compacts.

A retroreflective device securable to a highway by bonding thereto preferably with a viscous strip applied to the highway prior to solidifying cure of the strip includes a generally globular glass central member, a desirably pigmented adhesive layer over the central member and a plurality of peripheral globular glass members connected to the central member by the pigmented adhesive layer. A method for fabricating the retroreflective device is also disclosed.

The invention relates to anisotropic, reflective, magnetic flakes. In a liquid carrier and under influence of an external magnetic field, the flakes attract to one another side-by-side and form ribbons which provide higher reflectivity to a coating and may be used as a security feature for authentication of an object.

Dark colored roofing granules include an inert base particle coated with a composition including a metal silicate, a non-clay latent heat reactant, and a dark colored but solar reflective pigment.
