Selective laser-induced etching process-enabled double-cavity glass MEMS hydrogen sensor at room-temperature sensitivity

Ji Young Park, Byungkwon Jang, Jun Young Kim, Nosang Vincent Myung et autres

This paper introduces a glass-based MEMS hydrogen sensor that leverages single glass wafer cavity engineering along with a melamine–formaldehyde-derived nitrogen-doped carbon sphere (NCS) support bearing a Pt catalyst. A Laser induced selective wet etch process monolithically forms high-aspect-ratio vias and double cavities …

Regenerative Behaviors of Cokes-Deposited Ferrierite Zeolite during Gas-Phase Fluidized-Bed DME Carbonylation Reaction

Hyun Seung Jung, Rong Zhao, Woo Chang Sung, Ji Min Kim et autres

Gas-phase dimethyl ether (DME) carbonylation to methyl acetate (MA) is prone to be deactivated by coke depositions on Brønsted acid sites (Si-OH-Al groups) of ferrierite zeolite, and those inevitable coke depositions on the active sites, especially in eight-membered ring (8-MR) channels, are …

Compression and Transport Coupling Behavior in Thin Gas Diffusion Layers for Polymer Electrolyte Membrane Fuel Cell

Nak Won Kong, Kah-Young Song, Sun Young Jeong, Jun Young Kim

Compression and transport coupling behavior in gas diffusion layers (GDLs) influences the performance of membrane-electrode assemblies (MEAs) in polymer electrolyte membrane fuel cells (PEMFCs). Thin GDLs enhance volumetric power density and water removal, whereas their mechanical fragility and high compression sensitivity often …
