Abstract: A positive electrode active material including a first lithium composite oxide particle including a secondary particle formed by aggregation of one or more primary particles, and a coating oxide occupying at least a part of at least one of surfaces of the secondary particle, grain boundaries between the primary particles, or surfaces of the primary particles, the positive electrode active material satisfying an equation of 1.3?a/b?3.0, wherein a represents a max peak intensity at 2theta=44.75° to 44.80° and b represents a max peak intensity at 2theta=45.3° to 45.6° in X-ray diffraction (XRD) analysis using Cu K? radiation.

Abstract: A circuit board according to an embodiment comprises an insulating layer; an electrode layer disposed on the insulating layer; and a protective layer disposed on the insulating layer and including an opening vertically overlapping at least a portion of an upper surface of the electrode layer; wherein the electrode layer includes: a first layer disposed on the insulating layer; a second layer disposed on the first layer; a third layer disposed on the second layer; and a fourth layer disposed on the third layer, wherein a width of the second layer is greater than a width of the third layer, wherein a thickness of the second layer is greater than a thickness of the third layer, and wherein a height of an upper surface of the protective layer is equal to or less than a height of an upper surface of the third layer.

Abstract: An embodiment device includes an input module including a motor configured to generate a rotational force, an output module configured to receive power from the input module to be rotatable, and a connection module having a first side coupled to the input module and a second side, opposite the first side, coupled to the output module, wherein the connection module is configured to transmit the power from the input module to the output module.

Abstract: The present disclosure relates to strains of Thraustochytrium genus, including a high content of polyunsaturated fatty acids, and a method of producing a biomass using the same. According to the novel CJM01 microalgae of Thraustochytrium genus of the present disclosure, the content of lipids in the biomass and the content of unsaturated fatty acid such as docosahexaenoic acid in the biomass are high, so that the microalgae itself, a biomass produced by the culturing and fermentation of microalgae, a condensate of the biomass, and a dried product of the biomass are very useful as a feed composition.
