  • Nanomaterials
    Patent number: 12017284
    Abstract: The present application relates to a method for the production of a noble metal nanomaterial comprising: (A) adding an aqueous solution of a source of noble metal ions and a reducing agent to an aqueous solution of an organic compound to form a reaction mixture, wherein the organic compound is capable of undergoing 2D planar stacking in aqueous solution; and (B) separating the noble metal nanomaterial from the reaction mixture. The present application also relates to a noble metal nanomaterial manufactured according to said method.
    Type: Grant
    Filed: November 19, 2019
    Date of Patent: June 25, 2024
    Assignee: University of Leeds
    Inventors: Stephen Derek Evans, Sunjie Ye, Alexander Fred Markham, Patricia Louise Coletta

  • 3D expanding geometry
    Patent number: 9802165
    Abstract: This invention relates to bubble generation, in particular to microbubble generation in a microfluidic device, which bubbles may be useful as contrasting agents or drug delivery vehicles. The invention further relates to apparatuses, systems and methods for manufacturing said microbubbles, microbubbles produced by such methods and to their uses, e.g. in medical, diagnostic and other such applications. The microbubbles are preferentially formed using a microspray regime.
