Electrochromism of Polyaniline Film Incorporating a Red Quinone 1‐Amino‐4‐bromoanthraquinone‐2‐sulfonate
A red quinone 1‐amino‐4‐bromoanthraquinone‐2‐sulfonate (BA) was electroreduced to produce the corresponding colorless dihydroxy compound. The peak potential separation for the electrode reaction of BA was drastically decreased by covering it with polyaniline film: ca. 0.8 V for a bare ITO electrode, ca. 0.1 V for the…
Organic Electroluminescence Device Based on an Electrodeposited Poly(3‐substituted thiophen) Film
An electrochemically deposited composite film of poly(3‐substituted thiophen) and insulating nitrile butadiene rubber (NBR) was used as the emission layer of a polymer electroluminescence (EL) device. The composite film on an ITO substrate was uniform, and by using this film current leakage was prevented. The device w…
Vibrational entropy and microstructural effects on the thermodynamics of partially disordered and orderedNi3V
Samples of ${\mathrm{Ni}}_{3}$ V were prepared with two microstructures: (1) with equilibrium ${\mathrm{D}0}_{22}$ order, and (2) with partial disorder (having a large ${\mathrm{D}0}_{22}$ chemical order parameter, but without the tetragonality of the unit cell). For both materials, we measured the difference in their…
Comparative Study of XPS and DFT with Reference to the Distributions of Al in Tetrahedral and Octahedral Sheets of Phyllosilicates
Five phyllosilicate samples of dioctahedral smectite, mica, magnesium chlorite, saponite, and hectorite were studied using X-ray photoelectron spectroscopy (XPS) to determine the distribution of Al in the tetrahedral and octahedral sheets. The binding energies of the Al(2p) peaks in all the samples were obtained at 74…
Chemical Deposition of Ordered Conducting Polyaniline Film via Molecular Self-Assembly
Conducting polyaniline thin films were in situ deposited on silane-modified substrates through chemical polymerization. The resulting polymer films show good order and adhesion on the substrates. The thickness and conductivity of the resulting films can be tuned with the preparation conditions. The room temperature co…
Measuring Fiber Orientation in Nonwovens Part III: Fourier Transform
This paper addresses the development of an image analysis technique using the Fourier transform of the image to evaluate orientation in a fibrous assembly. The algorithms are evaluated using simulated images presented in Part I of the series. The results are compared with those for the tracking method presented in Par…
A Re-investigation of the Crystal Structure of the Perovskite PbZrO3 by X-ray and Neutron Diffraction
The crystal structure of the perovskite lead zirconate PbZrO 3 has been redetermined using single-crystal X-ray diffraction (Mo K α radiation, λ = 0.71069 Å). Single-crystal data at 100 K: space group. Pbam , a = 5.884 (1), b = 11.787 (3), c = 8.231 (2) Å, V = 570.85 Å 3 with Z = 8, μ = 612.6 cm −1 , D x = 8.06 Mg m −…
