- Precise control of atomic-layer Pd shells minimizes hot charge loss; demonstrated performance of antenna–reactor structure nanocatalyst - Research published in leading international journal JACS; core source technology for clean energy transition secured A research team led by Prof. Hyosun Lee of the Department of Materials Science and Engineering at the University of Seoul has announced next-generation eco-friendly photoelectrochemical catalyst technology developed using solar energy through research conducted jointly with Profs. Jeong Young Park and Hyotcherl Ihee of the KAIST Department of Chemistry. The team implemented a new catalytic technology that maximizes the utilization of hot charges in plasmonic metals. The novel technology significantly improves the efficiency of solar water splitting achievable with existing technologies. Because plasmonic metals can utilize the visible light region, which accounts for approximately 47% of sunlight, they are considered promising next-generation eco-friendly water-splitting catalysts. However, their performance has been limited by the rapid recombination of high-energy (hot) charges generated during sunlight absorption, which reduces reaction efficiency. ▶ Schematic diagram of the photoelectrochemical oxygen evolution reaction of Au@Pd nanoparticles To addre

The paper titled "CHEM: Causally and Hierarchically Explaining Molecules" by the joint research team of Professor Jong-June Jeon's laboratory (Kyungdong Woo, Soyong Cho, ChangHyun Kim) and Professor Jinhee Choi's laboratory (Donghyeon Kim, and Kimoon Na) at the University of Seoul has been accepted to the 2025 Conference on Information and Knowledge Management (CIKM, 2025), one of the top international conferences in computer science. CIKM is a prestigious international conference organized by the Association for Computing Machinery (ACM) and is highly competitive, having an acceptance rate of less than 20-30%. In computer science, acceptance at a top conference is more difficult than publication in a top journal.e ▶ Process of incorporating prior molecular information into the neural network model In this study, the joint research team developed a Graph Neural Network (GNN) model that can identify and predict causal subgraphs that determine the properties of molecules. Although existing GNN models rely solely on data information to identify the important molecular substructures, this study employs prior knowledge of functional groups in molecules to improve both the prediction performance and explainability of the neural network. This is a major achievement where actual chemical structure information in the tra

- Research team led by Professors Moonsup Han and Youngjun Chang, Department of Physics, University of Seoul - Simultaneous switching and memory functionality with aluminum oxynitride overlayers - Room-temperature processing & simple device structure: To open possibilities for next-generation low-power, high-speed information processing devices Summary A research team led by Professors Moonsup Han and Youngjun Chang in the Department of Physics at the University of Seoul has developed a novel field-effect transistor (FET) by integrating a two-dimensional semiconductor, molybdenum disulfide (MoS2), with an aluminum oxynitride (AlOxNy) overlayer. The device simultaneously achieves switching and memory functionalities, and its simple structure with room-temperature fabrication makes it suitable for large-area and flexible electronics. The team further revealed that the out-of-plane lattice vibrations (phonons) of MoS2 enhance the charge-trapping mechanism at the MoS2/AlOxNy interface, thereby improving memory performance. These findings highlight the potential of the device as a neuromorphic component for future information-processing systems. Details The University of Seoul research team has developed a new material–device structure that shows strong promise for next-generation neuromorphic computing based on

The University of Seoul announced that a paper co-authored by Junwoo Ha, a third-year undergraduate student in the Department of Mathematics, has been accepted to the main track of ACL 2025, the world’s premier conference in natural language processing (NLP). The paper, titled “One-Shot is Enough: Consolidating Multi-Turn Attacks into Efficient Single-Turn Prompts for LLMs,” introduces a groundbreaking framework that enhances the efficiency of AI security research. ACL (Association for Computational Linguistics) is the leading international conference in natural language processing and computational linguistics, attracting top researchers and industry leaders worldwide. This year’s conference will take place from July 28 to 30, 2025, at the Austria Center Vienna in Vienna, Austria. It is an exceptional achievement for an undergraduate to have a research paper accepted to the ACL main track. Ha’s study demonstrates that security attacks on large language models (LLMs) can be streamlined into a single-turn prompt, reducing token usage by up to 80% while achieving a 95.9% success rate in adversarial attacks. The research not only identifies hidden vulnerabilities in LLMs but also sets a new benchmark for the future of secure AI. While previous work has relied heavily on multi-turn prompts to increase attack
