  • Ion exchange system structure with a microtextured surface, method of manufacture, and method of use thereof
    Patent number: 6869712
    Abstract: A method for roughening a surface of an ion exchange system structure using laser interaction with a surface. The laser surface roughening process allows the use of a wide range of substrates such as metals, ceramics, silicates, polymers and the like, including varieties which can not be fabricated in a fine fibrous structure. The surface roughened ion exchange system structure may be used as an ion-exchange media in applications such as fuel cells, batteries, and other catalysis systems where a high surface exchange area is desirable.

  • Circuit elements using z-axis interconnect
    Patent number: 6791036
    Abstract: Methods for producing circuit elements the resultant circuit elements, and methods for making circuits therefrom are disclosed. A precursor circuit element includes a first insulating layer with conductor thereon and an electrically conducting member or bump, protruding from the conductor, that provide a shape to one surface of the precursor circuit element. A second insulating layer, including an adhesive, is placed onto the precursor circuit element and assumes the shape of the aforementioned surface of the precursor circuit element.

  • Method of preparing a surface for adhesion
    Publication number: 20030136505
    Abstract: A method of preparing a surface for adhesion is provided. The method includes providing an initiator that is configured to shadow a portion of a surface of a substrate, directing a laser toward the surface of the substrate to effect ablation of a non-shadowed portion of the substrate, thus forming structures on the surface of the substrate. An adhesive then may be applied to the surface of the substrate.
