The ‘Surface Control Technologies Using Electrolyte Plasma’ proposed by YU School of Materials Science and Engineering Professor Koh Young-gun’s (44) research team is receiving attention from academic circles all around the world.
Recently, Professor Koh announced his research results of reforming surfaces using electrochemical methods by inducing aqueous solution plasma explosions, which are similar to volcanic explosions, at micro-levels on top of metals and activating its discharge energy.
The outcomes of this study are receiving even greater attention as it is an eco-friendly technology that can replace the strong acid-based wet coating method that is currently being used. In addition to its structural properties such as anti-corrosion and anti-abrasion, functional properties such as bio antibacterial and photo catalysis were significantly improved, and as it is able to easily configure various colors, it is judged to be a platform material technology with high industrial potentials. There are anticipations that it can be used in various industrial sectors such as automobile, electronic parts, bio, and energy materials.
In particular, Professor Koh suggested the concept of controlling energy explosion intensity through strengthened and softened plasma for the first time to academic circles. Professor Koh stated, “Just as a volcanic cone or crater forms after a volcano explodes, the size and intensity of plasma explosions can also be artificially controlled. Furthermore, as it is possible to control electrophoresis (phenomenon where particles inside a solution that added voltage move toward a pole in one direction), phase transition (phenomenon where the phase of a substance changes due to external variables), expansion, and penetration, it is possible to create new materials that go beyond the limitations of existing organizations and compositions.”
The results of this study were published in the latest issue (Apr 2021) of the world acclaimed academic journal in materials <Progress in Materials Science> (impact factor 31.56) under the title ‘Principles, Structure and Performance of Electrolyte Plasma Surface Reform>.
It is more surprising that this worldwide research achievement was from the proprietary research capacities of YU, rather than as joint research among prestigious foreign universities or research institutes. All of the four researchers included in this paper as authors were research professors conducting research at Professor Koh’s lab or PhD researchers being advised by Professor Koh. This attests to the fact that YU’s research capacities in the materials sector have risen to global standards.
Recently, Professor Aleksey Yerokhin of the University of Manchester in England who is a global authority in this academic sector sent an e-mail to Professor Koh saying, “I would like to congratulate for publishing your research outcomes in a global journal. I am greatly interested in your paper.” He added, “I hope that we can develop a close cooperative relationship with the researchers at the University of Manchester.” Furthermore, there has been huge interest among researchers around the world in the materials sector in Professor Koh’s research achievements, as it was cited dozens of times in not even one month since the publication of his paper.
Professor Koh revealed his plans for follow-up research saying, “Based on this research, we plan to research advanced materials needed for the fourth industrial revolution by creating materials technologies that are currently unavailable by using the individual features of solids, liquids and gases in the future.”
Meanwhile, this research was conducted with the support of the middle-grade researcher support project by the Ministry of Science and ICT.
