  • Publication number: 20070183035
    Abstract: While gold wire grids have been used to polarize infrared wavelengths for over a hundred years, they are not appropriate for shorter wavelengths due to their large period. With embodiments of the present invention, grids with periods a few tens of nanometers can be fabricated. Among other things, such grids can be used to polarize visible and even ultraviolet light. As a result, such wire grid polarizers have a wide variety of applications and uses, such as, e.g., in the fabrication of semiconductors, nanolithography, and more.

  • Publication number: 20050215438
    Abstract: The present invention relates to methods and compositions for treating subterranean formations. More particularly, the present invention relates to polymersomes, viscosifying agents that comprise polymersomes, and associated methods of use. In some embodiments, the present invention discloses methods of treating a section of a subterranean formation that comprises the steps of providing a viscosified treatment fluid that comprises an aqueous-based component, and a viscosifying agent that comprises a polymersome; and treating the section of the subterranean formation. In other embodiments, the present invention discloses methods of viscosifying a treatment fluid, suspending particulates in a treatment fluid, fracturing a subterranean formation, providing sand control in a section of a subterranean formation, and encapsulating treatment fluid additives.

  • Patent number: 5948470
    Abstract: Methods of nanometer pattern formation and transfer onto a selected substrate are provided wherein a selected block copolymer is coated onto the selected substrate and a component of the block copolymer is chemically modified or physically removed so that the dense periodic pattern of the block copolymer can be transferred onto the selected substrate. Substrates prepared by these methods are also provided.
