우리 재료공학부와 미술대학이 공동으로 진행하는 금속공예 수업은 우리 학부 신입생 10명이 참여하여 재료공학의 이론을 배우고 이를 공예 실습을 통하여 체험하는 수업입니다.

이번 학기 신입생들의 작업과정과 그 결과물을 전시한 ‘금속공예 신입생 세미나 과제전’을 진행중이오니, 학부생, 대학원생, 교수님들의 많은 관람 부탁드립니다.



장소: 33동 1층 복도(WCU세미나실 앞)

일정: 2021년 6월 16일부터 약 2주간

Biodegradable & Stretchable Metallic Glass for Eco and Bio-Friendly Electronics (Advanced Science, 2021)

Biodegradable & Stretchable Metallic Glass for Eco and Bio-Friendly Electronics (Advanced Science, 2021)



Jae-Young Bae (Ph.D. Candidate from Prof. Seung-Kyun Kang group) has introduced the biodegradable and stretchable metallic materials for biodegradable electronic devices. He provided the insight the amorphous metals, metallic glass, has superior elastic strain without crystalline defect. He demonstrates excellent biodegradability and stretchability of nanoscale MgZnCa metallic glass. Also the research suggests fatigue resistive triboelectric nanogenerators which transform the mechanical energy to electrical energy. The research has posted online on Advanced Science, March 15 (https://doi.org/10.1002/advs.202004029)





Fully biodegradable MgZnCa metallic glass (MG) film is proposed for intrinsically stretchable electrodes with a high yield limit (≈2.6%), exploiting the advantages of amorphous phases with no crystalline defects. The top image shows the highly stretchable MgZnCa MG electrode integrating serpentine structure. Dissolution images of fatigue‐resistant triboelectric nanogenerator demonstrate the application of intrinsically stretchable MgZnCa MG in repeatable stretching mode.

The Best Award from 2020 X-Corps

Two practical problem research teams (team name, team SF), including researcher Yoo Ki Yoo, Jae-young Choi from the research team of Professor Inseok Choi of the Department of Materials Engineering, and Hyunwoo Kim and Minsuk Moon, undergraduate students in the Department of Materials Science and Engineering, won the Grand Prize at the final presentation of X-Corps at Seoul National University. Team SF has undertaken the development of a new type of research machine material with adjustable Poisson's ratio and a stretchable amplifier that maintains the aspect ratio of the utilized screen.

Atomic–layer–confined multiple quantum wells enabled by monolithic bandgap engineering of transition metal dichalcogenides (Prof. Gwan-Hyoung Lee’s group)

Professor Chul-Ho Lee group (Korea University) and Gwan-Hyoung Lee group (Seoul National University) collaborated to fabricate atomic-layer-confined multiple quantum wells via monolithic bandgap engineering. Layer-by-layer oxidation of bilayer WSe2 into WOx/WSe2 heterostructure formation of type I band structure. Atomic-layer-confined multiple quantum wells showed superlinear enhancement of photoluminescence with increasing number of quantum wells. This work was published on Science Advances by AAAS (American Association for the Advancement of Science).
