The global NAND Flash Memory market size is expected to reach approximately 78 trillion won in 2024, and Samsung Electronics takes the largest market share. The research team noted that although silicon nitride (SiNx) plays an important role as a charge trap layer in 3D NAND flash memory devices, there is a lack of methods to analyze its operating process. To address this, the research team devised a new analytical method that integrates high-resolution ellipsometry (SE) and electron energy loss spectroscopy (REELS). In this study, the light absorption state

- Investigating the Metabolic Dynamics of Transportation System through Fractal Dimension AnalysisA research team led by Professor Lee Seung-jae of the Department of Transportation Engineering of University of Seoul (President Won Yong-gul) has presented a new way to analyze the metabolic efficiency of the transportation system through fractal-dimensional analysis. The results of the study were published on Aug. 19, 2024, in the international renowned journal Transportmetrica A: Transport Science, which is listed in SSCI.The study analyzed the changes that occur when there are more vehicles on the roads in Seoul, and the researchers observed changes in the fractal dimension as traffic in the Seoul road system becomes congested and connected them with metabolic indicators to shed light on the efficiency of the transportation system. Here, the metabolic index refers to the efficiency of the use of resources based on the metabolic principle of living organisms and is defined as the actual utilization ratio of resources to resources put into the transportation system.(Top) Traffic Growth Patterns in Seoul Road System(Bottom right) Metabolism of living things and transportation systems(Bottom left) Relationship between fractal dimension and metabolic indicatorsAs a result of the study, the road system in Seoul begins to sho

- University of Seoul's Department of Physics, Korea Astronomy and Space Science Institute, and Jungwon University Joint Research- Resolved by rotational energy transfer to ultra-light dark matter- Looking forward to understanding the formation of super massive black holes and the role of dark matterThe University of Seoul (President Won Yong-gul) announced that a joint research team from University of Seoul, the Korea Astronomy and Space Science Institute, and Jungwon University has presented a new solution to the "final parsec" problem that occurs in the process of forming super massive black holes. The study presented the possibility of solving the bottleneck problem of black hole formation using "ultra-light dark matter" for the first time, and was published in the international journal Physics Letters B.The "final parsec" problem refers to a phenomenon in which the two black holes cannot get any closer at a distance of about 1 parsec (about 3.26 light-years). In the existing theory, black holes need stars or gas around them to get closer to each other, but at a distance of 1 parsec, they can't get any closer because there are very little of them.▲ A schematic diagram of an orbiting supergiant black hole binary starThe researchers suggested that ultra-light dark matter could solve this problem.
