  • Patent number: 11383426
    Abstract: An article has a curved surface. Disposed upon the curved surface is a plurality of patterns. Each pattern is defined by a plurality of spaced apart features attached to or projected into the curved surface. The plurality of features each have at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent features is about 1 nanometer and about 1 millimeter in at least a portion of the curved surface. The plurality of spaced apart features are represented by a periodic function.
    Type: Grant
    Filed: November 2, 2018
    Date of Patent: July 12, 2022
    Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.

  • Patent number: 9937655
    Abstract: Disclosed herein is a method comprising transporting a conduit and a template through a guide tube; the template being disposed on an outer surface of the conduit between the conduit and the guide tube; and transferring a texture from the template to the conduit as the conduit and the template are transported through the guide tube. Disclosed herein too is an apparatus comprising a guide tube; the guide tube being operative to facilitate a transfer of a pattern from a template to a conduit; a first feed spool and a first take-up spool for feeding the conduit through the guide tube and for taking up the conduit after it has travelled through the guide tube respectively; and a second feed spool and a second take-up spool for feeding the template through the guide tube and for taking up the template after it has travelled through the guide tube respectively.
