■ The Gwangju Institute of Science and Technology (GIST) announced on the 7th that a research team led by Professor Myunghwan Yoon of the School of Materials Science and Engineering has developed a next-generation catalyst technology. This technology uses a conductive polymer film (PEDOT:PSS) to evenly disperse a platinum (Pt) catalyst for hydrogen production throughout its interior, not just on the electrode surface. The team created a porous nanofiber structure with internal microchannels through sulfuric acid treatment and used a pulsed electrodeposition process to ensure uniform penetration of platinum into the film. This approach is expected to help solve the high-cost catalyst problem by achieving high hydrogen production performance with a smaller amount of platinum.
■ Pohang University of Science and Technology (POSTECH) announced on the 7th that Professor Junsuk Rho of the Departments of Mechanical Engineering, Chemical Engineering, and Electrical Engineering, and the Graduate School of Convergence Science and Technology, has been appointed as an Associate Editor for the international academic journal ‘Applied Physics Letters (APL)’. His three-year term begins on April 1, 2026. He will be responsible for editing papers in the fields of metamaterials, nanophotonics, nanofabrication, and nanodevices. APL is a prestigious international journal with a 65-year history published by the American Institute of Physics (AIP).
