Interfacial coupling of pitch- and PAN-based carbon fibers with carbon nanotubes in polyethersulfone for electromagnetic interference shielding

Min Jeong Ko, Yoonsang Kim, Sang‐Woo Kim, Jinsu Kim et autres

Abstract Lightweight thermoplastic polymer shields to suppress electromagnetic interference (EMI) exhibit a trade-off between processability and performance. In this study, we introduced a co-processing step in polyethersulfone (PES) to enrich the perimeter of short carbon fibers (CFs) with single-walled carbon nanotubes (CNTs). …

A Zero-Knowledge Proof-based Telemetry Data Integrity Mechanism for Policy Compliance Verification

Jinsu Kim, Eunsun Choi, Namje Park

텔레메트리 데이터의 무결성은 자동화와 안전 의사결정의 핵심 기반이지만, 기존 방식은 애플리케이션 신뢰와 원시데이터 보관에 의존하여 프라이버시 보호와 감사 가능성 측면에서 한계를 가진다. 이에 본 논문은 값을 공개하지 않고 정책 준수 여부를 입증할 수 있는 영지식증명 기반의 무결성 메커니즘을 제안한다. 제안된 메커니즘은 커밋, …

Performance based evaluation of chloride penetration resistance of high performance mortar with hollow microspheres developed for floating marine structures

Jinsu Kim, Jae-Bin Jo, Jang-Ho Jay Kim

Due to the lack of land space from increasing population, number of marine structure construction has increased recently. In order to construct sustainable marine structures, the durability performance of concrete used for the construction in marine environments has to be guaranteed. Unfortunately, …
