  • Colorimetry and image analysis determination of specific surface area
    Patent number: 11189046
    Abstract: A method for determining a specific surface area of a given material includes preparing plural samples of a dye and the given material; imagining the plural samples to generate digital images; calculating from the digital images, a saturation S for each of the plural samples; selecting a single saturation S value that corresponds to an excess dye condition; and calculating the specific surface area Ss based on the single saturation S value, for the given material.
    Type: Grant

    Date of Patent: November 30, 2021
    Assignee: KING ABDULLAH UNIVERSITY OF SCIENCE AND TECHNOLOGY
    Inventors: Juan Carlos Santamarina, Marisol Salva Ramirez
  • Angle of repose system and method
    Patent number: 11060855
    Abstract: A system for measuring an angle of repose includes an angle of repose device that holds a granular material, and a portable smart device having a camera and a processor. The angle of repose device is configured to open a slit to allow a first part of the granular material to remain in an upper chamber while a second part of the granular material moves freely, due to gravity, from the upper chamber to a lower chamber. The portable smart device uses the camera to take a digital image of the first part and the second part of the granular material and uses an app installed on the processor to calculate an internal angle of repose and an external angle of repose.
