  • Patent number: 9293659
    Abstract: A method for fabricating a microstructure to generate surface plasmon waves comprises steps of: preparing a substrate, and using a carrier material to carry a plurality of metallic nanoparticles and letting the metallic nanoparticles undertake self-assembly to form a microstructure on the substrate, wherein the metallic nanoparticles are separated from each other or partially agglomerated to allow the microstructure to be formed with a discontinuous surface. The present invention fabricates the microstructure having the discontinuous surface by a self-assembly method to generate the surface plasmon waves, thus exempts from using the expensive chemical vapor deposition (CVD) technology and is able to reduce the time and cost of fabrication. The present invention also breaks the structural limitation on generation of surface plasmon waves to enhance the effect of generating the surface plasmon waves.

  • Publication number: 20140037857
    Abstract: A method for applying a fixed image onto at least one surface of a component in an electrochemical device is described. The component is usually formed of an alumina material. An image-forming material is first applied onto the component surface in its green state. The mark or image is applied in a desired pattern by an additive process, such as direct-write or screen-printing. The component is then heated at a sintering temperature sufficient to ensure conversion from the green state into a fired ceramic state. The sintering temperatures are also sufficient to fix the image upon the surface of the component. The image can be read by the human eye, or by various machine-readable techniques. Related methods for monitoring the location and status of a ceramic electrochemical cell component during its manufacture and during other processing steps are also described.
