Abstract: In certain example embodiments, a coated article includes respective layers including diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and/or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is scratch resistant and durable.

Abstract: The invention is about the preparation of novel highly transparent zeolite-doped polymer and zeolites monolayers. External coating of the zeolite crystals by covalently linked functionalized alkoxysilane derivatives allows for an efficient dispersion of the nano zeolite particles into an organic liquid monomer; the following co-polymerisation process leads to a hard, insoluble and transparent material containing said zeolites. Optical properties such as colour, refractive index, Abbe number or photochromism can be fine tuned by simply changing zeolite loading, while transparency is maintained.

Abstract: An optical fiber preform is assembled by inserting core rod segments axially end to end inside of a first glass overclad tube having a first, relatively low concentration of a given impurity that contributes to signal attenuation in an optical fiber to be drawn from the preform. The first overclad tube with the contained core rod segments are inserted in a second glass tube having a second concentration of the given impurity which is higher than the first concentration. The wall thickness of the first overclad tube is preferably less than that of the second overclad tube, thus reducing the amount of high purity glass needed to form the first overclad tube and attendant manufacturing costs. The core rod segments may include salvageable remnants from a single long core rod produced, for example, by vapor axial deposition (VAD).
