Abstract: The present disclosure provides a composite material. The composite material includes 20 to 40 weight percent (wt. %) of a polymerizable component; 6 to 40 wt. % of ceramic fibers; and 30 to 70 wt. % of nanoclusters. Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.

Abstract: The present disclosure provides an article having a substrate having a first nanostructured surface and an opposing second surface; and a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces. The micropattern may have an open area fraction greater than 80%. The traces of the conductor micropattern may have a specular reflectance in a direction orthogonal to and toward the first surface of the substrate of less than 50%. The nanostructured surface may include nanofeatures having a height from 50 to 750 nanometers, a width from 15 to 200 nanometers, and a lateral spacing from 5 to 500 nanometers. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields.

Abstract: A nonwoven web including a multiplicity of non-respirable, polycrystalline, aluminosilicate ceramic filaments entangled to form a cohesive mat, the polycrystalline, aluminosilicate ceramic filaments having an average mullite percent of at least 75 wt. %. The cohesive mat preferably exhibits a compression resilience after 1,000 cycles at 900° C. when measured according to the Fatigue Test, of at least 30 kPa. Insulation articles including the cohesive mats or formed by chopping the ceramic mats into ceramic fibers, pollution control devices including the insulation articles, and methods of making the non-respirable, polycrystalline, aluminosilicate ceramic filaments and fibers, nonwoven webs, insulation articles, and pollution control devices, are also described.
