  • Publication number: 20180229262
    Abstract: The present invention relates to methods for producing a composite material comprising a substrate and a monolayer of nanoparticles self-assembled thereupon, the method comprising: (i) providing a suspension comprising a solvent and nanoparticles dispersed therein; (ii) providing a substrate comprising a surface with void spaces for accommodating said nanoparticles; (iii) contacting one end of said substrate with said suspension in a closed system, to thereby gradually dispose said suspension over said substrate by capillary action, thereby forming a film of suspension on said substrate; and (iv) allowing evaporation of said film of suspension, thereby forming a monolayer of nanoparticles self-assembled in said void spaces on said surface of the substrate. The present invention also relates to composite material produced by the methods disclosed herein.

  • Patent number: 9909203
    Abstract: A method for fabrication of metal film with nanoapertures is provided. The method includes the steps of providing a nanopatterned template including a plurality of nanostructures, depositing of the metal film onto the nanopatterned template, and thermally induced dewetting of the metal film to define the nanoapertures in the metal film by diffusion and reflow of the metal film.

  • Patent number: 9633685
    Abstract: According to embodiments of the present invention, a method of writing to an optical data storage medium is provided. The method includes receiving a plurality of data elements, each data element having one of a plurality of values, wherein each value of the plurality of values is associated with a wavelength, and forming, for each data element, a nanostructure arrangement on the optical data storage medium, the nanostructure arrangement configured to reflect light of the wavelength associated with the value of the data element in response to a light irradiated on the optical data storage medium. According to further embodiments of the present invention, a method of reading from an optical data storage medium and an optical data storage medium are also provided.
