Qualitative Stability Analysis of Soft Hand Exoskeleton Based on Tendon-driven Mechanism
Autor: Pilwon Heo, Youngjin Na, Jung-Hoon Park, Jung Kim
Publikováno v: International Journal of Precision Engineering and Manufacturing. 21:2095-2104
There exist several hand exoskeletons systems that provide assistive force to the user for strength enhancement or rehabilitation. However, the lack of stability analyses for such systems has made it difficult to ensure that these systems can apply a

End-group cross-linked sulfonated poly(arylene ether sulfone) via thiol-ene click reaction for high-performance proton exchange membrane
Autor: Jong-Chan Lee, Junghwan Kim, Pilwon Heo, Jusung Han, Kihyun Kim
Publikováno v: Journal of Power Sources. 401:20-28
End-group cross-linked sulfonated poly (arylene ether sulfone) (C-SPAES) membranes with varying degree of cross-linking density are prepared by in-situ casting and heating of thiol-terminated SPAES (SH-SPAES) solutions containing different amounts of

Cross-Linked Sulfonated Poly(arylene ether sulfone) Containing a Flexible and Hydrophobic Bishydroxy Perfluoropolyether Cross-Linker for High-Performance Proton Exchange Membrane
Autor: Wonchan Hwang, Jong-Chan Lee, Kihyun Kim, Pilwon Heo, Ji-Hoon Baik, Yung-Eun Sung
Publikováno v: ACS Applied Materials & Interfaces. 10:21788-21793
Here we show a simple and effective cross-linking method to prepare a high performance cross-linked sulfonated poly(arylene ether sulfone) (C-SPAES) membrane using bishydroxy perfluoropolyether (PFPE) as a cross-linker for fuel cell applications. The

Enhanced physical stability and chemical durability of sulfonated poly(arylene ether sulfone) composite membranes having antioxidant grafted graphene oxide for polymer electrolyte membrane fuel cell applications
Autor: Pilwon Heo, Heock-Hoi Kwon, Jungmoon Bae, So-Won Choi, Ki-Hyun Kim, Jong-Chan Lee, Min-Young Lim
Publikováno v: Journal of Membrane Science. 525:125-134
Sulfonated poly(arylene ether sulfone) (SPAES) composite membranes were prepared using antioxidant grafted graphene oxide as a filler for polymer electrolyte membrane fuel cell (PEMFC) applications. SPAES was synthesized via condensation polymerizati

Rechargeable PEM Fuel-Cell Batteries Using Porous Carbon Modified with Carbonyl Groups as Anode Materials
Autor: Kazuyo Kobayashi, Yuta Yamamoto, Pilwon Heo, Masahiro Nagao, Takashi Hibino
Publikováno v: Journal of The Electrochemical Society. 162:F868-F877
Rechargeable fuel-cell batteries (RFCBs) operate by hydrogen storage and release at the anode, while oxygen evolution and reduction reactions occur at the cathode. High-surface-area porous carbon was treated with HNO3 to produce an anode material wit
