Abstract: Provided is a concentration measuring device which includes: a main pipe through which a fluid whose concentration is to be measured flows; a flow cell having a fluid passage and a light passage formed to pass through the fluid passage; a spectrometer capable of measuring absorbance for each wavelength of the source light transmitted to the flow cell and the received light receiving from the flow cell; and an optical cable connecting the flow cell and the spectrometer with each other, wherein the flow cell is separated from the main pipe to be provided separately, and a fluid pipe is connected to the flow cell, so that the fluid flows from the main pipe to the flow cell through the fluid pipe using a pitot tube.

Abstract: A display device includes first and second light emitting regions; first and second pixel electrodes in the first and second light emitting regions, respectively; a first organic layer in the first light emitting region, including first and second light emitting layers; a second organic layer in the second light emitting region, including a third light emitting layer; a common electrode on the first and second organic layers; a wavelength conversion pattern on the common electrode, overlapping the first organic layer, and wavelength-converting light of a first color into light of a second color, different from the first color; and a light transmitting pattern on the common electrode, overlapping the second organic layer. The third light emitting layer and one of the first and second light emitting layers emit light of the first color, and another one of the first and second light emitting layers emits light of the second color.

Abstract: A positive electrode active material for a lithium secondary battery has a mixture of microparticles having a predetermined average particle size (D50) and macroparticles having a larger average particle size (D50) than the microparticles. The microparticles have the average particle size (D50) of 1 to 10 ?m and are at least one selected from the group consisting of particles having a carbon material coating layer on all or part of a surface of primary macroparticles having an average particle size (D50) of 1 ?m or more, particles having a carbon material coating layer on all or part of a surface of secondary particles formed by agglomeration of the primary macroparticles, and a mixture thereof. The macroparticles are secondary particles having an average particle size (D50) of 5 to 20 ?m formed by agglomeration of primary microparticles having a smaller average particle size (D50) than the primary macroparticles.
