The Giant Magellan Telescope and Coquimbo Regional Government Sign Strategic Partnership to Strengthen Chile’s Astronomy Industry

Seoul National University College of Engineering announced that a research team led by Prof. Seung Hwan Ko (Department of Mechanical Engineering, SNU), in collaboration with Prof. Gang Chen at MIT and research teams from Hyundai Motor Company and Kia (Materials Research & Engineering Center and Thermal Energy Total Development Group), has designed and fabricated a large-area Scalable Transparent Radiative Cooling (STRC) film applicable to vehicle windows. Through real-vehicle evaluations conducted under various climatic and driving conditions, the team demonstrated both energy-saving and carbon reduction effects.

This research was supported by the Global Leader Research Center funded by the Ministry of Science and ICT and the National Research Foundation of Korea, and was published online on February 4 in the internationally renowned journal Energy & Environmental Science.

Breaking away from conventional robots that perform only predefined functions once fabricated, researchers have developed a next-generation artificial muscle that can change its shape in real time, recover from damage, and even be reused.

Seoul National University College of Engineering announced that a joint research team led by Prof. Jeong-Yun Sun (Department of Materials Science and Engineering) and Prof. Ho-Young Kim (Department of Mechanical Engineering), with Yun Hyeok Lee, Seungwon Moon, and Min-gyu Lee as first and co-first authors, has developed a new type of dielectric elastomer actuator (DEA) using a phase-transitional ferrofluid (PTF) that behaves as a solid at room temperature but becomes fluid-like and highly flexible when exposed to external stimuli such as heat or magnetic fields.

The study was published on March 21 in Science Advances, a leading international journal published by the American Association for the Advancement of Science (AAAS).

Acoustic metamaterials can shape sound well, but most rely on rigid structures that are hard to reconcile with transparency, broadband performance and flexibility. Researchers have now developed a hydrogel metapad that brings these properties together in one platform, improving ultrasound imaging of blood vessels and the heart while suggesting new opportunities for underwater acoustics.
