The phase relations of Mg-Ga-Fe-O spinel solid solutions have been analyzed in a topological approach using composition diagrams. Oxides with the nominal compositions Mg1 − x Ga2 − 2x Fe3x O4 + δ and Mg1 − x Ga2x Fe2 − x O4 + δ (with x varied in steps of 0.1) prepared by a pyrohydrolytic process and air-annealed at 12…
An electromechanical system is constructed to explore the electrical properties of well-aligned horizontal suspended single-walled carbon nanotube (SWCNT) arrays under the influence of tensile stretching. The suspended SWCNT array sensing structure consists of a well-grown SWCNT array suspended between two separated m…
DC and intrinsic low-frequency noise properties of p-channel depletion-mode carbon nanotube field effect transistors (CNT-FETs) are investigated. To characterize the intrinsic noise properties, a thin atomic layer deposited (ALD) HfO(2) gate dielectric is used as a passivation layer to isolate CNT-FETs from environmen…
We have studied the effect of an external acoustic wave on bubble displacements inside an aqueous foam. The signature of the acoustic-induced bubble displacements is found using a multiple light scattering technique, and occurs as a modulation on the photon correlation curve. Measurements for various sound frequencies…
This article describes a method for synthesizing an environmentally friendly overbased magnesium oleate detergent using oleic acid and active-60 magnesium oxide as materials. Reaction conditions including solvent, molar ratio of active-60 magnesium oxide to oleic acid, molar ratio of methanol to active-60 magnesium ox…
Poly(2,2-dimethyl-1,3-propylene oxalate) was synthesized from oxalyl chloride and 2,2-dimethyl-1,3-propane diol. The polymer was characterized by inherent viscosity, FT-IR, XRD, SEM, 1H-NMR, 13C-NMR, DSC, and TGA. The polymer uptake behavior towards Pb(II), Cd(II), and Hg(II) ions was studied by the batch equilibrium…
Ab initio calculations are used to model small Au n nanoclusters and Au m SH clusters. The results for the Au6, Au8, and Au20 clusters demonstrate that the substitution of a SH group for a Au atom gives a stable cluster of the same geometry if the Au atom has an acute bond angle and a negative effective charge. The ex…
Silicone fluid has been applied in cable rejuvenation for decades to “cure” existing water trees. However, whether it inhibits future water tree initiation is not known. An electrical aging test has been carried out at 5 kV/mm (127 V/mil) based on a sample which includes semicon electrodes on both sides of the insulat…
An optically active isothiouronium-attached polythiophene 1 poly has been prepared for the first time by oxidative polymerisation of (S)-3-(3-(N-(2-(2-methoxyethoxy)ethyl)-N-(1-phenylethyl)-S-isothiouronio)propoxy)-4-methylthiophene 1 with FeCl3. The analysis carried out using gel-permeation chromatography allows us t…
We examine the dynamics of a two-dimensional drop on an inclined substrate vibrating vertically. The drop is assumed to be driven by its contact lines, while its shape is determined by a quasistatic balance of surface tension, gravity, and vibration-induced inertial force. It is shown that, if the dependence of the in…
Synthesis of boehmite (γ-AlOOH) nanorods were performed by using aluminum nitrate and sodium hydroxide as starting materials in conditions of controlled pH value of reaction mixture, temperature and holding time. X-ray diffraction, transmission electron microscope, high resolution transmission electron microscope, sel…
Based on the generalised source method, a new method for calculating the light diffraction on one-dimensional dielectric diffraction gratings with an arbitrary profile is proposed. The method is an alternative to the widely used Fourier modal method because it possesses the same possibilities in defining different gra…
In crystal growth of mineral species or different compositional members of a solid solution on one another, the degree of lattice mismatch at their interface affects the growth pattern of the precipitating mineral phase. Fast layer-by-layer growth of magnesian calcite on pure calcite (101̅4) substrates has been observ…

Abstract The oxidative degradation of the contracted carbaporphyrinoid 3,8,13,18‐tetraphenyldithiaethyneporphyrin, which contains an acetylene moiety embedded in the macrocyclic framework, was investigated. The light‐induced, regioselective cleavage of the macrocyclic ring was observed during exposure to dioxygen affo…
Abstract Size effects in pseudoelastic polycrystalline shape memory alloys are studied by considering a representative spherical laminated domain (subgrain) and its interfacial energy at three scales: at the subgrain boundaries, at the austenite–martensite interfaces, and at the twin boundaries. Two sources of interfa…
The spin Hamiltonian parameters (the anisotropic g factors and the hyperfine structure constants) and the local structure for the rhombic Cu 2+ center in rutile ( TiO 2 ) are theoretically investigated using the formulas of these parameters for a 3d 9 ion in rhombically elongated octahedra. From the studies, the plana…
Abstract A general approach to construct one‐dimensional face‐to‐face alignment of porphyrin/fullerene nanowires has been developed. This system uses extended trans‐ dihydroxotin(IV) porphyrin and trans‐ dicarboxylate‐substituted [60]fullerenoacetic diacid compounds. The nanowires are arranged in regular one‐dimension…
Porous nano-titanium dioxide (TiO(2)) particles with anatase framework were prepared by using an effective template of hydrophobic ionic liquid, i.e., N, N-bis [2-methylbutyl] imidazolium hexafluorophosphate ([PPim][PF(6)]). The nano-TiO(2) particles were characterized with TEM and BET, resulting in the distribution o…
