Journal ArticleDOI
Hydration behavior of perfluorinated and hydrocarbon-type proton exchange membranes: Relationship between morphology and proton conduction
TL;DR: In this article, the relationship between morphology and proton conduction for Nafion membranes and hydrocarbon-type proton exchange membranes was investigated by small-angle X-ray scattering (SAXS) and atomic force microscopy (AFM).
Journal ArticleDOI

TL;DR: The mechanism of gas permeation in Nafion membranes for polymer electrolyte fuel cells has been investigated from the viewpoint of free volume in this paper, where the positron annihilation lifetime (PAL) technique was used to quantify free volume.
Journal ArticleDOI
A two-dimensional molecular network structure of trimesic acid prepared by adsorption-induced self-organization
TL;DR: In this article, a two-dimensional molecular network of trimesic acid on Au(111) was visualized by in situ scanning tunneling microscopy with submolecular resolution.
Journal ArticleDOI
Versatile Helical Polymer Films: Chiroptical Inversion Switching and Memory with Re‐Writable (RW) and Write‐Once Read‐Many (WORM) Modes
Journal ArticleDOI
Electrochemical, AFM and QCM studies on ferritin immobilized onto a self-assembled monolayer-modified gold electrode
TL;DR: In this paper, a ferritin-immobilized electrode based on self-assembled monolayer (SAM)-modified gold electrodes was developed for nanomaterial synthesis for potential magnetic, catalytic and biomedical sensing applications.
