Abstract Three binuclear copper(II) complexes of N,N′,N″,N'″-tetrakis(2-aminoethyl)-1,4,8,11-tetraazacyclotetradecane (taec), [Cu2(taec)N3](ClO4)3 (1), [Cu2(taec)(NCO)](ClO4)3 (2), and [Cu2(taec)(NCS)2](ClO4)2·H2O (3), were prepared and characterized. The crystal structures of these complexes were determined by single…

Since the experiment of Shechtman et al. which suggests the crystal with the pentagonal symmetry (quasicrystal), there has been a lot of interest in the quasiperiodic systems. These can be regarded as being intermediate between ordered and disordered systems, and novel physical properties are expected. In fact, the qu…

Abstract Fourier transform infrared (FT‐IR) studies of poly(ethylene terephthalate) (PET)/poly/(amide‐6,6) (PA) blends are presented. The blends were prepared in the molten state and in solution with trifluoroacetic acid (TFA) as the solvent. The PET/PA blend is a complex system containing, two crystallizable polymers…

Low Energy Electron Diffraction (LEED) is one of the most commonly used techniques for crystal surface characterization at the atomic level, but is frequently only used as a monitor of surface order. The full potential of LEED as a tool for surface crystallography is not often exploited, primarily because the method h…

An established method for measuring complex rf magnetic permeability is based on the change in inductance and resistance of a coaxial transmission line upon insertion of a sample toroid. It is not necessary to wind coils on the toroid or correct for geometric demagnetization factors. The use of modern commercial imped…

The breakdown voltage, the upturn voltage, and the nonlinearity of the ZnO varistors are significantly influenced by the Sb 2 O 3 and SiO 2 contents, as well as by the β→γ transition of the Bi 2 O 3 phase. The lattice parameter of spinel is influenced by the coexisting Bi 2 O 3 phase. Antimony oxide disperses into the…

A new method to evaluate rotational viscosity η in ferroelectric liquid crystals is proposed. This method is based on the measurement of a polarization switching current upon field reversal. It is shown that a full width at half-maximum of the current peak t w is equal to 1.76η/ P s E , while the area gives twice the…

High-resolution synchrotron powder X-ray data have been used to solve the structures of I2O4 and Al2Y4O9 by profile decomposition into individual structure amplitudes, followed by application of standard Patterson and direct methods. The data were obtained from a series of spectra recorded with a small linear position…

Crack propagation in SiC‐whisker‐reinforced MoSi 2 was studied. In particular, the deflection angles of the cracks were examined to determine the degree to which they are affected by the whisker reinforcement. The composite studied was hot‐pressed MoSi 2 with 20 vol% vapor‐liquid‐solid β‐SiC whiskers. A substantial di…
