  • Rechargeable power source for mobile devices which includes an ultracapacitor
    Patent number: 11244791
    Abstract: Provided herein is a rechargeable power source that can be quickly charged and used for charging mobile and cordless devices. The power source includes an ultracapacitor which comprises a composite structure including, for example open graphene structures or graphene nanoribbons attached to an oxide layer. The oxide layer is on a metal foil surface. The oxide layer includes more than one metal atom.
    Type: Grant

  • Processes and methods of aggregating, analyzing, and reporting distributed storage system properties within a central platform using storage descriptor data structures
    Patent number: 10866871
    Abstract: Example implementations described herein are directed to a storage descriptor data structure that can represent characteristics of the dataset stored in an underlying volume without requiring the dataset in the volume to be migrated for processing. Such data structures are more compressed than the original data structure and can therefore facilitate storage allocation before the migration is conducted.

  • Structure for electric energy storage using carbon nanotubes
    Patent number: 10546698
    Abstract: A composite electrode structure and methods of making and using thereof are disclosed. The structure has a metal substrate with a metal oxide layer. The average thickness of the metal oxide layer is less than 150 nm, and comprises at least a first metal and a second metal, wherein the first metal and the second metal are different elements. A plurality of carbon nanotubes is disposed on a first surface of the metal oxide layer. At least a portion of the carbon nanotubes are disposed such that one end of the carbon nanotube is positioned at least 5 nm below the surface of the metal oxide layer.
