  • Patent number: 6926967
    Abstract: A heat treatable coated article including a solar management layer for reflecting infrared (IR) or the like, is provided between a substrate and an overlying dielectric layer. An underlying dielectric layer between the substrate and solar management layer is optional.

  • Patent number: 6919119
    Abstract: An electronic or opto-electronic device or a chemical sensor comprising: an interpenetrating network of a nanostructured high surface area to volume ratio film material and an organic/inorganic material forming a nanocomposite. The high surface area to volume film material is obtained onto an electrode substrate first, such that the nano-scale basic elements comprising this film material are embedded in a void matrix while having electrical connectivity with the electrode substrate. For example, the film material may comprise an array of nano-protrusions electrically connected to the electrode substrate and separated by a void matrix. The interpenetrating network is formed by introducing an appropriate organic/inorganic material into the void volume of the high surface area to volume film material. Further electrode(s) are defined onto the film or intra-void material to achieve a certain device.
