Students of Department of Materials Science and Engineering, YU published theses through famous international journals and their research capability is accepted by the outside.


A thesis reported by co-authors Nam Ga-hyeon (23) and Lee Geon (22) of 4th Grade of Department of Materials Science and Engineering was inserted in a famous international journal in ceramic area, Ceramics International, with 4.527 of IF in November and, in August, the thesis reported by Lee Seung-ah (22) as lead author was inserted in Journal of Asian Ceramic Societies, IF 3.125.


  The theses reported by them are the performances of a task performed by Functional Materials, Devices Lab of Department of Materials Science and Engineering, YU. Nam Ga-hyeon and Lee Geon reported the result of a study on maximization of efficiency of energy storage materials. They manufactured a ferroelectric ceramic material for charge/discharge of high energy in nano-film type and developed a technology to maximize energy storage.


  Lee Geon said, “Electrochemical energy storage such as batteries has the advantage to supply a device with electric energy for a long time but is not suitable for instantaneous charge and discharge. However, capacitor using static electricity is suitable for instantaneous charge and discharge but is difficult to store large energy. The developed nano-structure material is suitable for instantaneous charge and discharge, has high energy storage density, and may be used for electric cars which require high energy instantaneously.”

  Lee Seung-Ah reported the result of a study on “energy harvesting technology to use the energy discarded in daily life. Lee Seung-Ah developed a ceramic-based intelligent energy harvest material. The technology may substitute traditional power supply technology from batteries and power may be continuously supplied by a wireless sensor without charging or other control. Lee Seung-Ah said, “IoT wireless sensor network, which is highlighted as a core hardware technology in the 4th industry, requires a power source technology to substitute traditional batteries or supplement battery lifetime. The developed material may be manufactured at about 10% of costs compared with traditional energy harvest materials and durability and environmental credibility may also be guaranteed. Commercialization of energy harvesting technology may be further encouraged.”


  Professor Ryu Jeong-ho of Department of Materials Science and Engineering who advised them commented, “The technology for efficient generation and storage of energy is essential to solve world energy and environmental issues. Undergraduate students developed a technology for efficient conversion of electric energy to be discarded in daily life using a low-priced material and a technology on a material for instantaneous charge and discharge with high dense storage of energy. Additional studies are required for commercialization but such performance is meaningful in the respect that new materials may be developed and applied to application devices for efficient generation and storage of energy.


  Meanwhile, the study was conducted with the support by Senior researcher support project and Global frontier project of National Research Foundation of Korea.
