  • Materials for moisture removal and water harvesting from air
    Patent number: 10486102
    Abstract: A material for moisture removal and/or water harvesting from air may include a hydrophilic material containing micropores and a low water activity material confined within the micropores of the hydrophilic material. Apparatuses containing such materials and methods for moisture removal and/or water harvesting from air by using such materials are also described.
    Type: Grant
    Filed: October 14, 2015
    Date of Patent: November 26, 2019
    Assignee: The Hong Kong University of Science and Technology
    Inventors: King Lun Yeung, Shammi Akter Ferdousi
  • Incorporating metals, metal oxides and compounds on the inner and outer surfaces of nanotubes and between the walls of the nanotubes and preparation thereof
    Patent number: 10238762
    Abstract: A multi-walled titanium-based nanotube array containing metal or non-metal dopants is formed, in which the dopants are in the form of ions, compounds, clusters and particles located on at least one of a surface, inter-wall space and core of the nanotube. The structure can include multiple dopants, in the form of metal or non-metal ions, compounds, clusters or particles. The dopants can be located on one or more of on the surface of the nanotube, the inter-wall space (interlayer) of the nanotube and the core of the nanotube. The nanotubes may be formed by providing a titanium precursor, converting the titanium precursor into titanium-based layered materials to form titanium-based nanosheets, and transforming the titanium-based nanosheets to multi-walled titanium-based nanotubes.
