  • Publication number: 20210040387
    Abstract: A method of preparing a quantum dot nanoparticle is disclosed. The method includes the step of reacting one or more cation precursors including one or more of Groups 12 and 13 elements with one or more anion precursors including one or more of Group 15 elements to prepare a quantum dot nanoparticle, wherein the reaction of the cation precursors and the anion precursors is carried out while supplying a compound represented by Chemical Formula 1. A quantum dot nanoparticle prepared by the preparation method, a quantum dot nanoparticle having a core-shell structure containing the quantum dot nanoparticle as a core, and a light emitting element comprising the quantum dot nanoparticle having a core-shell structure are also disclosed.

  • Patent number: 8950084
    Abstract: A semi-drying method of a washing machine, and a ventilating structure and a control apparatus for the same. In the semi-drying method, the dehydration and disentanglement of cloth are repeated plural times, and a washing tub is rotated at a designated dehydration speed for a time longer than that of the conventional dehydrating operation so as to minimize the jamming of the cloth into water pores of the washing tub, thereby increasing the dehydration degree of the cloth compared to the conventional dehydrating operation, removing offensive odors from the cloth, preventing damage to the cloth, allowing a user to select the duration of a semi-drying operation and to see the state of the semi-drying operation, and ventilating the washing tub during the semi-drying operation to improve the dehydration degree of the cloth.
