Abstract:
Disclosed herein are graphene coatings characterized by a porous, three-dimensional, spherical structure having a hollow core, along with methods for forming such graphene coatings on glasses, glass-ceramics, ceramics, and crystalline materials. Such coatings can be further coated with organic or inorganic layers and are useful in chemical and electronic applications.
Abstract:
The invention relates to a method to increase the strength of a form body of lithium silicate glass ceramic, which after it has a desired end geometry and after the application of a material which influences its surface to form a coating, is subject to a heat treatment. To create a surface compressive stress through the replacement of lithium ions by alkali ions of greater diameter at least that region not covered by the application layer is covered by a melt or paste consisting of or containing a salt of an alkali metal with ions of greater diameter and the form body is in contact with the melt or paste for a period of time t at a temperature T and the melt or paste is subsequently removed from the form body.

Abstract:
Composite structures composed of a coating applied to a substrate and provided, along with a process for applying a coating to a substrate to form the composite structure. Coatings described herein provide at least one of the following properties: nano-sized surface roughness; enhanced hydrophobic function; high transmittance; improved hardness; improved scratch resistance; and desirable bending properties. The coating method includes mixing coating particulates having an average particle diameter of 1 µm or less with a transfer gas, transferring the mixture to an application nozzle, and spraying coating particulates on the substrate under low pressure conditions to form a coating having an average particle diameter of 100 nm or less.
