- Atomistic details in defect evolution in W under neutron irradiation unveiled
- Atomistic details in defect evolution in W under neutron irradiation unveiled Prof. Keonwook Kang and his research team published an original article, "Free-surface effect on displacement cascades in BCC W: molecular dynamics study", in Nuclear fusion (IF: 3.706, JCR top 8.82%). This paper investigates defect formation and growth mechanisms near the tungsten surface under neutron irradiation using molecular dynamics simulation. Increased interstitial mobility near the surface suppresses defect recombination events and promotes formation of extended defects such as dislocation via vacancy clustering. Theses vacancy loops can develop into a micro-void or act as a source of crack, which triggers catastrophic brittle fracture. This study identifies the origin of extreme brittle behavior of W and has significant applications for designing W and its alloys as facing materials in nuclear fusion environment.

- Novel Motor for Next-Generation Semiconductor Photo-Lithography Systems
- Novel Motor for Next-Generation Semiconductor Photo-Lithography Systems Professor Jun Young Yoon in the Department of Mechanical Engineering at Yonsei University has worked with MIT researchers to design and develop a new motor for high-precision high-throughput next-generation EUVL (Extreme Ultra-Violet Lithography) systems. While commercially available linear iron-core synchronous motors have the potential for high thrust, they can emit significant vibrations and acoustic noise, thereby impairing accuracy of high-precision manufacturing systems such as in photo-lithography machines, also known as semiconductor chipmakers. Professor Yoon and his co-workers 1) found, for the first time, root causes of such vibro-acoustic noise emitted by linear iron-core permanent magnet motors, 2) proposed and validated a new motor magnetic design, called a fine-tooth motor, to reduce the noise while increasing thrust performance compared with conventional linear motors, and 3) further reduced the noise through a double-sided mechanical configuration of the new fine-tooth motors. The work has been published in multiple journals and conferences including IEEE Transactions on Industrial Electronics (TIE) and IEEE/ASME Transactions on Mechatronics (TMECH). For his research accomplishment, Professor Yoon won the ‘Young Engineer Award’ from the Korean Society for Precision Engineering (KSPE) and the ‘Young Scientist Award’ in the 2019 ASML Korea Tech Talk, which is also covered in media (links provided below). “We hope our new magnetic and mechanical solutions of high-force low-noise linear motors for the EUVL help the semiconductor industry pushing the limits even further to make our everyday lives faster, easier, and smarter“, says Professor Yoon.

- Vibration & sound power reduction of a thin plate-like structure excited by complex inputs
- Vibration & sound power reduction of a thin plate-like structure excited by complex inputs Many engineering structures are composed of plates and plate-like components, such as the outer casing of a washing machine, printed circuit boards (PCBs) in electronic devices, the ship hull and deck. These structures are vulnerable to complex inputs, combination of force and moment components, from vibrational sources such as motors, pumps, and collision between parts. The resulting vibration and noise emissions jeopardize the integrity of the engineering structure. Yonsei research team led by Professor No-Choel Park in the school of Mechanical Engineering proposed a new method for reducing the vibration and sound radiation of a thin plate excited by complex input sources. A set of new formulas for the sound radiation of baffled and unbaffled plates are derived by substituting the moment components of the plates with the equivalent couples using finite difference analysis. This approach allows to calculate sound power purely by the input location and amplitude of each component. Thus, it enables faster, more accurate calculations than the existing methods such as the average radiation efficiency analysis and the radiation mode analysis. The results of the research were published in Journal of the sound and vibration with the title “Calculation and reduction of sound radiation from a thin plate structure excited by complex inputs”.

- Vibration absorption of space tethers using pendulum-type elastic metamaterial작성일 2020.08.26
- Vibration absorption of space tethers using pendulum-type elastic metamaterial Professor No-Cheol Park in Mechanical Engineering and his research team have designed pendulum-type elastic metamaterials for vibration absorption of space tethers. Space tether is highly exposed to external disturbances such as meteoroid collisions. Disturbances are transmitted to the satellite via tether cables and affect the satellite's orbit and posture. The pendulum-type elastic metamaterial absorbs vibration propagating through the resonance of the internal structure. In addition, his research team proposed a method to absorb vibrations over a wider frequency range using multi-bandgaps. The results of the research were published in the International Journal of Mechanical Sciences in July 2020 with the title “Experiment and analysis of a space tether with pendulum-type elastic metamaterials” and Korea patent with the title “Satellite tether device using elastic metamaterial” has been registered.
