Abstract Using chemical transport reactions well-shaped crystals of In 2 (SO 4 ) 3 and Ga 2 (SO 4 ) 3 can be prepared in a temperature gradient ( T 2 → T 1 ) using Cl 2 as transport agent. The two modifications of In 2 (SO 4 ) 3 were formed by variation of the transport temperature. The low-temperature modification of…

Distinct improvement in adhesion of diamond coatings on hard metal substrates was achieved by following substrate surface pretreatment [1] : First WC was removed from the substrate surface by etching with Murakami solution (K3[Fe(CN)6] in KOH), after which the Co binder network was etched with H2SO4/H2O2 solution. The…

We show that the variation of the structural unit in tellurite glasses is due to the charge transfer from modifier atoms to ${\mathrm{TeO}}_{6}$ octahedra with use of first-principles molecular-orbital calculations. Mulliken overlap populations indicate that the oxygen coordination number of a Te atom reduces as the c…

The interaction of N-(p-methoxy-o-hydroxybenzylidene)-p-aminopyridine(I) and N-(p-methoxy-o-hydroxybenzylidene)-m-aminopyridine(II) with certain p-alkoxybenzoic acids results in the formation of liquid crystals. Specifically, as established by optical microscopy, DSC and X-ray diffraction studies, complexes of I with…

Based on the fact that the Al 3 Mn phase is closely related to the Al-Mn decagonal quasicrystal, three subunits of the Al-Mn decagonal quasicrystal are deduced from the structure of the Al 3 Mn phase. The existence of these subunits is confirmed by the high-resolution electron microscopy image of the Al-Mn decagonal q…

Abstract Hybrid biomaterials derived from a water‐soluble derivative of polypyrrole, poly(sodium 4‐(3‐pyrrolyl)butanesulfonate), and soluble collagen have been synthesized by chemical polymerization of the 4‐(3‐pyrrolyl)butanesulfonate monomer in a collagen solution. Interaction between the two polymers was evident in…

Existing colorimetric methods for determining phosphorus (P) in citrate‐bicarbonate‐dithionite (CBD) extracts from soils and sediments require pretreatments of extracts prior to the determination of the element. A method is proposed for the determination of P in CBD extracts without any chemical treatments. Maintainin…

Molecular dynamics simulations of the time-correlation functions that appear in the Green–Kubo expression for the shear viscosity are reported for liquid argon over a wide range of densities. The potential part of the microscopic stress tensor is separated into contributions due to the repulsive and attractive branche…

The partial discharges produced by internal defects in solid insulation have been investigated using the ultra high frequency (UHF) technique. The work has shown that the discharges produced by a virgin cavity generate a UHF signal that may be detected using this UHF technique. The discharges are observed as a series…

A stack of seven 15 μ thick polyvinlyl alcohol (PVA) foils was irradiated with 16 MeV electrons. In order to allow for the electrons’ slowing-down until stopping, six 5 mm thick Al plates had been inserted in between these PVA foils. The fractional depth distribution of the PVA destruction is derived from the change i…

We study the velocity correlation function of a selected particle in a suspension of interacting Brownian particles. Experimentally, the velocity correlation function can be observed with diffusing wave spectroscopy. The function has also been determined in computer simulation. We assume a wide separation of time scal…
