New cooling paints were developed by exploiting the vaporization heat of water. These systems were prepared using various ratios of three copolymer components N-isopropylacrylamide (NIPAAm), butyl acrylate (BA), and N,N-dimethylacrylamide (DMAAm). The homopolymer of NIPAAm dissol...

In order to reveal adsorbed states of water molecules on faujasite-type zeolites (FAU) systematically, twenty five kinds of FAU were prepared in this study: Na ions in FAU with Si/Al ratios of 1.0, 1.2, 1.7, 2.4, and 3.5 were exchanged by each Li, K, Rb, and Cs ions. High-resolut...

Solid-state 1H nuclear-magnetic-resonance (NMR) measurements of polyaniline doped by HClO4, H2SO4, and H3PO4 were performed with magic-angle-spinning (MAS) methods to reveal the effects of protonation on chain arrangements and the electrical conductivity of polyaniline. In this s...

In order to investigate new ionic plastic crystals, differential-scanning-calorimetry (DSC), nuclear-magnetic-resonance (NMR), and electrical conductivity measurements were carried out in NR4BBu4 (R = Me, Et, Pr, Bu, Pen) salts. DSC measurements showed a low entropy change of 29....
