Abstract: A nozzle according to an embodiment includes: a metal portion, which defines a penetration hole therein; and a ceramic portion, which surrounds the metal portion, where the metal portion includes a first region and a second region having a narrower diameter than the first region, the ceramic portion surrounds the second region, and an end of the metal portion close to a discharging end of the nozzle is spaced apart from an end of the ceramic portion close to the discharging end.

Abstract: A prelithiated negative electrode, and a secondary battery including a prelithiated electrode, including a negative electrode current collector; and a negative electrode active material layer present on at least one surface of the negative electrode current collector. The negative electrode active material layer includes high-capacity artificial graphite having no carbon coating. The negative electrode active material layer is prelithiated, and the content of lithium intercalated to the prelithiated negative electrode active material layer is 3% to 5% based on the lithium content intercalated when the negative electrode is charged to 100%.

Abstract: A complementary thin film transistor (TFT) includes a substrate and a first TFT and a second TFT disposed on the substrate, wherein a first conductive semiconductor layer of the first TFT and a second gate electrode layer of the second TFT are disposed in the same layer and include the same material.

Abstract: An apparatus for forming a window of a display panel includes a mold configured to hold a plate in a concave portion, wherein the concave portion has a predetermined shape, and a transfer part configured to sequentially transfer the mold to a heating part, a forming part, and a cooling part. The heating part includes first and second heating modules respectively positioned on top and bottom portions of the mold and configured to apply heat to the top and bottom portions of the mold. The forming part is positioned above the mold and configured to jet a high-temperature gas onto the heated plate. The cooling part includes first and second cooling modules respectively positioned on the top and bottom portions of the mold and configured to cool the top and bottom portions of the heated plate. The mold is tilted at a predetermined angle relative to a horizontal plane.
