  • Plasmonic Nanoparticle Layers with Controlled Orientation
    Publication number: 20230084516
    Abstract: A method of making an article comprising one or more layers of plasmonic nanoparticles located between opposing layers of dielectric materials and an article comprising one or more layers of plasmonic nanoparticles located between opposing layers of dielectric materials.
    Type: Application
    Filed: August 17, 2022
    Publication date: March 16, 2023
    Applicant: Virginia Tech Intellectual Properties, Inc.
    Inventors: Guoliang Liu, Assad U. Khan
  • Nanocomposite graphene polymer membrane assembly, and manufacturing method thereof
    Patent number: 10841709
    Abstract: A membrane hetero-structure includes a polymer layer and a single-layer or multi-layer graphene sheet disposed on the polymer layer. The membrane hetero-structure is tensioned across a frame having an opening such that both the polymer layer and the graphene sheet extend across the opening. An optional rigid member is provided in a center of the membrane to be spaced apart from edges of the opening. The assembly of the frame and membrane hetero-structure forms an electrostatically driven micro-electro-mechanical system (MEMS) or sound generation and recording apparatus. In one instance, when a voltage signal is applied between an electrode layer parallel to the membrane and contacts on the frame that are electrically connected to the graphene sheet, the membrane hetero-structure is actuated.
    Type: Grant
