Patents by Inventor Watchareeya Kaveevivitchai

Watchareeya Kaveevivitchai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11581542
    Abstract: A cathode material of a lithium-ion battery and a fabricating method thereof, and a lithium-ion battery are described. The cathode material of the lithium-ion battery has hexaazatriphenylene embedded quinone (HATAQ) and/or its derivative small molecules, which have multiple redox-active sites and can form intermolecular hydrogen bonds to form a graphite-like layered structure. When HATAQ and/or its derivative small molecules are used as a cathode material, a stable structure can be maintained during a charge and discharge process and during lithium ions entering and exiting.
    Type: Grant
    Filed: February 14, 2021
    Date of Patent: February 14, 2023
    Assignee: NATIONAL CHENG KUNG UNIVERSITY
    Inventors: Teng-Hao Chen, Watchareeya Kaveevivitchai, Meng-Siou Wu

  • Patent number: 10449253
    Abstract: A method of delivering or sequestering anesthetic agents by adsorption of such agents by porous partially fluorinated compounds which display high weight adsorption capacities. Such compounds have a non-covalent organic framework with a central ring, such as hexa, tetra, tri or di substituted benzenes which may be substituted or unsubstituted with alternating electron poor and electron rich groups such as tetra-, tri-, or di-fluorobenzenes, oligocyanobenzenes, oligochlorobenzene, and benzene, pirydone, triazole, pyrazole, pyridine, and substituted benzenes so that the compound forms a porous supramolecular structure; and adsorbs the anesthetic agent within the pores of a the compound.
