The new material made up of a combination of ‘metals-minerals-organic matter’ proposed by YU School of Materials Science and Engineering Koh Young-gun (43, photo) and his research team is receiving global attention.
Professor Koh recently published his research results on new materials that allows wide-ranged property control never before realized in the past by combining the strengths of different materials such as metals, minerals and organic matter. In particular, this new material proposed by Professor Koh has a 3D structure similar to a flower with a large surface area, thus confirming that the material property was significantly improved.

Generally, metals have outstanding mechanical properties such as intensity and ductility, but are weak against the environment and corrosion. Meanwhile, minerals have excellent anti-corrosive properties, but it has lower stability against impact. On the other hand, organic matter allows relatively higher diversity in materials compared to metals and minerals. Therefore, Professor Koh combined the strengths of the individual materials in this study to propose a 3D complex structure for the first time int he world that can supplement weaknesses and maximize surface area. He thus proposed a creative concept that can procure both material structure and functionality. This new material is judged to have very high industrial potential as it can be used in a wide range of fields including energy, environment and bio.
The research results are scheduled to be published in the July edition of the globally acclaimed academic journal <Progress in Materials Science, impact factor 23.725) under the title ‘Hybrid Mineral-Organic Material with a Nature Replicating 3D Structure’.
It is more surprising that this worldwide research achievement was from the proprietary research capacities of YU, rather than as joint research among domestic and foreign universities or research institutes. All of the researchers including in this paper as authors are research professors conducting research at Professor Koh’s lab or PhD researchers being advised by Professor Koh. <Right on photo.

Professor Koh stated, “Many outstanding researchers from both Korea and abroad earned their degree at YU and are currently conducting research. The research achievements prove that YU’s research capacities have stepped up to global standards in the new materials sector.” He also revealed his future research plans saying, “Following this research, I plan to conduct research for developing advanced materials with multiple functions that exceed structure limits by using material combination technologies that expand the concept of physical metallurgy and surface engineering.”
Meanwhile, this research was conducted with the support of the middle-grade researcher support project by the Ministry of Science and ICT.”
