Fabrication and characterization of GA-crosslinked PBI/PVA blend membranes with polydopamine surface modification for alkaline water electrolysis applications

Seong Jun Jang, Tae Kyung Lee, Jun Ho Park, Km Nikita et autres

The membrane used in alkaline water electrolysis systems has performance limitations due to the trade-off between ionic conductivity and durability in alkaline environments. To address this limitation, a polybenzimidazole/poly (vinyl alcohol) (PBI/PVA) blend-based ion-solvating membrane was fabricated, then chemically crosslinked with glutaraldehyde …

Ionic liquid-functionalized graphene oxide-reinforced-poly(carbazole) nanocomposite anionic membranes for high-performance water electrolysis

Mohammad Mahbub Kabir, Yeshi Choden, Leonard D. Tijing, Sherub Phuntsho et autres

Anion exchange membrane water electrolysis (AEMWE) promises low-cost green hydrogen production but is limited by the anion exchange membranes (AEMs) that must couple high hydroxide (OH − ) ion conductivity (IC) with mechanical robustness and alkaline durability. Rigid ether-free poly(carbazole) backbones help …

Hydrophobic Metal–Organic Frameworks Enable Superior High-Pressure Ammonia Storage through Geometric Design

Mingyu Gu, Radhakrishnan Anbarasan, Ho-Jun Cho, Jinhyuk Choi Jinhyuk Choi et autres

Hydrophobic metal–organic frameworks (MOFs) are typically overlooked for ammonia storage due to weak host–guest interactions. Here, we demonstrate that four structurally analogous aluminum-based MOFs exhibit a counterintuitive behavior whereby framework geometry, rather than ligand hydrophilicity, determines high-pressure NH 3 adsorption performance. The …

Copper Electrodeposition on CNT Fibers for Lightweight Conductor Materials with High Electrical Performance

Eunkyoung Shim, Serin PARK, Sang Yong Nam, Jae-Hong Lim

The importance of lightweight materials has been growing significantly, not only in the development of next-generation transportation systems such as Urban Air Mobility (UAM) and high-efficiency electric vehicles, but also in the aerospace and robotics industries. In these sectors, conductive materials are …

Study on TGV Metallization by Copper Filling with Additives

Serin PARK, Eunkyoung Shim, Sang Yong Nam, Jae-Hong Lim

As Moore's law reached its limits, 3D packaging integration has emerged as a promising solution to overcome this problem. Initially wire bonding was used for 3D integration,. However, wire bonding requires additional space for connecting wires to chips. To address this limitation, …

Benign integrated synthesis–casting of transparent aramid films with superior dielectric and mechanical properties

Yeonhae Ryu, Seunggun Yu, Jaemin Im, Wonseong Song et autres

Aramid films are widely used as high-performance dielectric and structural materials, yet conventional fabrication from Kevlar fibrils requires prolonged dispersion in concentrated acids, leading to non-uniformity, opacity, and degraded mechanical properties. In this study, we report a benign integrated synthesis–casting process that …
