  • PLASMA TREATED ABRASIVE ARTICLE AND METHOD OF MAKING SAME
    Publication number: 20100255254
    Abstract: An abrasive article, such as a structured abrasive article, can be treated by subjecting it to plasma whereby the outer surface can be eroded exposing at least a portion of the abrasive particles dispersed within a cross-linked binder forming the abrasive composites. Depending on the process conditions for the plasma treatment, it is possible to erode only a small portion or substantially all of the cross-linked binder from the outer surface. Thus, the initial cut-rate of the abrasive article can be controlled since it is possible to precisely control the degree, height, or area of the exposed abrasive particles.

  • PERMEABLE NANOPARTICLE REFLECTOR
    Publication number: 20100189922
    Abstract: An optically-responsive multilayer reflective article is formed by applying a dilute solution or suspension of metallic nanoparticles to an optically-responsive detection layer. The solution or suspension is allowed to dry to form a semicontinuous liquid- or vapor-permeable light-reflective layer that will permit a liquid or vapor analyte to pass through the light-reflective layer to cause an optically-responsive change in the detection layer in the presence of the analyte.
