Abstract: A thin film based nanoporous alumina template has been developed which allows the in situ removal of an electrically insulating alumina barrier layer at the pore bases. This barrier free nanoporous system has great utility for electrodeposition of a wide variety of nanowire materials. An exemplary multilayer thin film precursor is provided comprising Al (anodization layer), Ti (diffusion barrier) and Pt (active electrode) on a Si substrate. Aluminum anodization in sulfuric acid with a subsequent applied voltage ramping program produces a Pt electrode at the base of the nanopores without the additional steps of alumina removal, barrier layer dissolution, and metal deposition onto the pore bottoms.

Abstract: A resin molded product and a fine metal powder producing material are placed into a treating vessel. The fine metal powder producing material is brought into flowing contact with the surface of the resin molded product, thereby producing a fine metal powder, and forming a metal layer of the fine metal powder on the surface of the resin molded product. In this process, the metal layer of the fine metal powder can be formed firmly and at high density on the surface of the resin molded product. The metal layer exhibits a function as an electrically conductive layer. Therefore, a metal film having an excellent thickness accuracy, an excellent surface smoothness and a high peel strength can be formed in a simple manner on the metal layer by carrying out an electroplating treatment. In addition, it is possible for the metal layer itself to exhibit functions or properties such as an ornamentality.

Abstract: A heat treatable coated article including an infrared (IR) reflecting layer (e.g., of or including Ag), the coated article being able to attain a ?E* (glass side) no greater than about 3.0, more preferably no greater than 2.5, and even more preferably no greater than 2.0, following or due to heat treatment (e.g., thermal tempering). Accordingly, low-E (i.e., low emissivity) coated articles of certain embodiments of this invention appear from the glass side thereof visually similar to the naked eye both before and after heat treatment. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windshields, or any other suitable applications. In certain embodiments of this invention, an exemplary layer stack includes: glass/Si3N4/NiCr/Ag/NiCr/Si3N4. Other materials may instead be used without departing from the scope and/or spirit of the instant invention which is a low-E matchable product.
