  • Calcium hydroxide nanoparticles synthesized with carob pulp extract
    Patent number: 11696925
    Abstract: Calcium hydroxide nanoparticles (Ca(OH)2NPs) synthesized using carob pulp extract may be hexagonal nanoparticles with a diameter ranging from about 31.22 nm to about 81.22 nm. The Ca(OH)2NPs may be synthesized by heating ethylene glycol, adding calcium hydroxide to the ethylene glycol to provide a first mixture, heating the first mixture, adding a carob pulp aqueous extract to the first mixture to form a second mixture, heating the second mixture, adding sodium hydroxide (NaOH) to the second mixture to form a third mixture, heating the third mixture, resting the third mixture at room temperature after heating, centrifuging the third mixture, collecting a colloid sediment, extracting any unwanted contaminants from the colloid sediment, and drying the colloid sediment to obtain Ca(OH)2NPs.
    Type: Grant
    Filed: September 14, 2020
    Date of Patent: July 11, 2023
    Assignee: KING SAUD UNIVERSITY
    Inventors: Mohamad Saleh Alsalhi, Sandhanasamy Devanesan, Rawan Ibrahim Salem Alkhalaf, Hajer Saad Abdullah Allayed, Nasser Raqe Rashed Alqhtani, Mohammed Ghazi Alkindi, Osama Ghurmullah Mohammed Alghamdi
