    (2016-08-02) Majumder, Mainak; Gao, Wei; Ajayan, Pulickel Madhavapanicker; Narayanan, Tharangattu; Pradhan, Bhabendra K.; Rice University; United States Patent and Trademark Office
    A process for conversion of conventional sand granules (or other particulates) to a ‘core-shell’ adsorbent granules in which GO (or GO-f) coating imparts nano structural features on the surface of the sand granules (or other particulates). Such materials are useful in a variety of engineering applications such as water purification, catalysis, capacitors, proppants, casting, and magnetic shielding.
