Title: Innovations in Water Filtration: The Contributions of Yu Hang Leung
Introduction
Yu Hang Leung is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of water filtration through his innovative patent. His work focuses on developing advanced materials that enhance the efficiency of water purification processes.
Latest Patents
Yu Hang Leung holds a patent for "Deeply grooved nanoparticle-coated nanofibers." This invention provides a water filtration membrane capable of removing heavy metal ions, filtering out particulates, filtering out bacteria, and eliminating herbicides and volatile organic compounds (VOCs) from water. The membrane consists of a mat of randomly oriented nanoparticle-coated nanofibers. These nanofibers are covalently bonded to a plurality of uniformly distributed ceramic nanoparticles, which are embedded in or adhered to the surface of the polymer nanofibers through reactive functional groups. The ceramic nanoparticles feature a pattern of deep grooves on their surfaces, enhancing their effectiveness. The bonding of the nanoparticles to the nanofibers is robust enough to retain the nanoparticles during water flow through the filtration membrane. The diameter of the nanofibers ranges from 50-200 nm, while the nanoparticles are less than 40 nm in size, exhibiting a zeta potential of -40 to -45 mV in a dispersion medium. The average size of the nanoparticle deep grooves is approximately 1.2 nm or less.
