Latest Patents
One of Hyun Jeong's latest patents is titled "Light-emitting diode having zinc oxide nanorods and method of fabricating the same." This invention improves the light extraction efficiency of typical light-emitting diodes (LEDs) by incorporating one-dimensional ZnO nanorods. The light extraction efficiency is enhanced by approximately 31% due to the waveguide effect of ZnO sub-microrods, compared to an LED without the nanorods. The method involves producing various shapes of ZnO microrods and nanorods using a simple non-catalytic wet chemical growth method at low temperatures on an indium-tin-oxide (ITO) top contact layer without a seed layer. The crystal morphology and density of the ZnO structures can be modified by controlling the pH value and growth time. The waveguide phenomenon in each ZnO rod is observed using confocal scanning electroluminescence microscopy (CSEM) and micro-electroluminescence spectra (MES).
Another significant patent relates to a process for preparing phenolic polymers utilizing peroxidase. This invention offers a method for polymerizing phenolic monomers with peroxidase, eliminating the need for toxic formalin or costly plant-derived peroxidase. The polymerization occurs in the presence of a polar organic solvent under mild conditions, resulting in phenolic polymers with excellent water and chemical resistance and high yield.
