Abstract: Metal-coated zirconia articles have at least one surface that is a surface-treated surface. The surface-treated surface is a phosphate-treated surface. At least a portion of the surface-treated surface is covered with a layer of metal. The metal covering adheres more strongly to the surface-treated surface than to an identical surface that is not surface-treated.

Abstract: An antimicrobial article includes a supporting layer and an antimicrobial layer. The antimicrobial layer has a first major surface at least partially formed by a plurality of particles and a second major surface coupled to the supporting layer. Each particle of the plurality of particles is formed by a bead of nonconductive material. A first set of the particles include beads coated by a first conductive material.

Abstract: A light control film includes a microstructured layer including a plurality of microstructures defining a plurality of grooves therebetween. The light control film further includes a light absorbing material disposed in each of the plurality of grooves. The light absorbing material includes a plurality of first particles. Each first particle includes a polymeric bead including an outer surface. Each first particle further includes an outer layer disposed on the outer surface of the polymeric bead. The outer layer of the first particle includes a metal compound.

Abstract: An article. The article includes a substrate, wherein the substrate having two opposing major surfaces; and particles coated with a metal oxide on the substrate: particles coated with a metal on the substrate; wherein the coated particles are randomly distributed on or in the substrate; and wherein at least some of coated particles are discrete particles.
