TL;DR: Nan ofibers proved to be promising materials as a proton exchange membrane and the composite membrane containing nanofibers may have potential application for use in fuel cells.
Journal ArticleDOI
Gas transport properties in thermally cured aromatic polyimide membranes
TL;DR: Aromatic polyimide derived from 2,2′-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) and 3,3′-diaminodiphenylsulfone (m-DDS) has been synthesized to facilitate the study of relationships between the polymer structure and the gas transport properties (permeability and selectivity) as discussed by the authors.
Journal ArticleDOI
Reversible coordination and facilitated transport of molecular nitrogen in poly((vinylcyclopentadienyl)manganese) membrane
TL;DR: In this article, le cinetique et les constantes d'equilibre for le transfert d'azote a travers des membranes constituees par un copolymere de methacrylate d'octyle and d'un complexe de manganese sont determinees.
Journal ArticleDOI
Surface modification of poly(L: -lactic acid) affects initial cell attachment, cell morphology, and cell growth.
Manae Yamaguchi,Toshio Shinbo,Toshiyuki Kanamori,Pi-Chao Wang,M Niwa,Hiroyoshi Kawakami,Shoji Nagaoka,Kohichiro Hirakawa,Masahiro Kamiya +8 more
TL;DR: Since the plasma treatment not only accelerated cell adhesion but also enabled cells to proliferate in the form of sheets resembling biological tissue, it is believed that oxygen-plasma treatment is extremely effective for modifying surfaces of materials used for tissue regeneration.
Journal ArticleDOI
Gas transport properties of soluble aromatic polyimides with sulfone diamine moieties
TL;DR: Aromatic polyimides derived from 2,2'-bis(3,4-dicarboxyphenyl) hexafluoropropane dianhydride (6FDA) and 3,3'- or 4,4'-diaminodiphenylsulfone (m-DDS) have been synthesized with a chemical imidization as mentioned in this paper.
