A method of driving the non-volatile memory device in accordance with various embodiments of the present invention includes inducing an asymmetrical local energy state (ALES) generated due to instantaneous acceleration of electrons injected into the semiconductor layer, and removing the ALES from the semiconductor layer, for recovery of the semiconductor layer. https://scholar.dgist.ac.kr/handle/20.500.11750/60316 Title: 약물 전달 디바이스 Author(s): 이지훈; 양승운; 박석호 https://scholar.dgist.ac.kr/handle/20.500.11750/60309 Title: Cu Nanoparticle Infiltration via Metal-Organic Decomposition Ink for Superior Mass Activity in CO Electroreduction Author(s): Choi, Juhyung; Park, Sejin; Kim, Dayeon; Kim, Hyun Chul; Yun, Hyewon; Hong, Yewon; An, Hyun Ji; Lee, Taemin; Lee, Noho; Kim, Jaeeun; Nam, Dae-Hyun; Oh, Hyung-Suk; Hwang, Yun Jeong Abstract: Achieving stable operation at high currents remains challenging for gas diffusion electrode (GDE)-based CO electrolyzers. Herein, we demonstrate the importance of Cu nanoparticle infiltration into the microporous layer to enrich local CO accessibility and mitigate electrolyte crossover. A facile GDE preparation method is developed via the doctor-blading method using a Cu metal-organic decomposition (Cu MOD) ink to produce well-dispersed nanoparticles across the porous layer. This design produces highly selective C2+ products at -1200 mA cm-2 from the CO electroreduction reaction, achieving a remarkably high mass activity of approximately -28,000 A g-1. It is found that the Cu electrodes prepared by MOD improve a stable balanced gas-liquid-solid interface by CO transport across the hydrophobic microenvironment of the inherent microporous layer. Our insights offer perspectives on a scalable strategy for optimizing catalyst positioning and advancing stable GDEs with high mass activity. 2025-09-30T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60256 Title: AI를 이용한 일회박출량 산출 장치 및 방법 Author(s): 양현림; 이형철; 김민수; 정철우
