Abstract: A quantum dot including a core that includes a first semiconductor nanocrystal including zinc and selenium, and optionally sulfur and/or tellurium, and a shell that includes a second semiconductor nanocrystal including zinc, and at least one of sulfur or selenium is disclosed. The quantum dot has an average particle diameter of greater than or equal to about 13 nm, an emission peak wavelength in a range of about 440 nm to about 470 nm, and a full width at half maximum (FWHM) of an emission wavelength of less than about 25 nm. A method for preparing the quantum dot, a quantum dot-polymer composite including the quantum dot, and an electronic device including the quantum dot is also disclosed.

Abstract: The present disclosure relates to a cleaning liquid composition and a cleaning method using the same. A polishing slurry composition according to an embodiment of the present disclosure includes: a chelating agent containing an organic salt; and an anionic surfactant.

Abstract: A cleaning solution composition and a cleaning method using the cleaning solution composition are provided. The cleaning solution composition includes a chelating agent including a first organic acid and a second organic acid, and an etching agent including a fluoride compound.

Abstract: An apparatus for treating a substrate of the present invention includes a buffer unit, an inversion unit, a first transfer chamber, a second transfer chamber, a first cleaning chamber, and a second cleaning chamber. The first transfer chamber, the inversion unit, and the second transfer chamber are sequentially arranged in one direction. The first cleaning chamber is disposed at one side of the first transfer chamber, and the second cleaning chamber is disposed at one side of the second transfer chamber. A first main transfer robot provided in the first transfer chamber directly transfers the substrate between the buffer unit, the inversion unit, and the first cleaning chamber. The second main transfer robot provided in the second transfer chamber directly transfers the substrate between the buffer unit, the inversion unit, and the second cleaning chamber.

Abstract: A composition for dissolving abrasive particles, and a cleaning method using the composition are provided. The composition includes a sulfur-containing organic acid, a fluorine ion-containing compound, and a solvent, and a turbidity change rate (%) measured at 60° C. for 15 minutes may be in a range of ?80 to ?99.

Abstract: A method for recognizing a music score included in an image and various information included in the music score, which may be obtained through a camera provided in a mobile terminal without requiring a separate editing program. The method includes detecting a region with staff lines from the image including the music score; detecting a region with an accompaniment chord from the image by taking the region with the staff lines and a region with a musical note into consideration; extracting and removing the staff lines from the music score included in the image; recognizing the musical note by extracting the musical note from the image, from which the staff lines have been removed; recognizing the accompaniment chord by extracting the accompaniment chord from the image, from which the staff lines have been removed; and generating data for reproducing a sound source corresponding to the musical note and accompaniment chord.
