We demonstrate a template-free synthetic approach for the preparation of a highly conductive Cu/Cu(2)O nanocomposite electrode by a chemical reduction process. Cu(2)O octahedra were prepared through chemical dehydrogenation of as-synthesized Cu(OH)(2) nanowire precursors. To provide a sufficiently electron-conducting network, the Cu(2)O particles were transformed into Cu/Cu(2)O nanocomposites b...

The topological features of the formation (Co40Fe40B20)15(LiNbO3)85 composite films deposited by ion-beam method on a metal electrode Cr/Cu/Cr has been investigated. presence dielectric layer between upper Cr and CoFe–LiNbO3 film with thickness dox ~ 15 nm established. difference in size granules near amorphous volume shown. A model (Co40Fe40B20)x(LiNbO3)100–x nanocomposite at initial stage gro...

The geochemical investigation of shales from the Early to Middle Cretaceous Chichali Formation in Hazara Basin was conducted determine origin, tectonic setting and evolution, paleo-weathering conditions, paleo-oceanographic reconstruction. research included a comprehensive field survey, sample collection, analysis variety main, trace, rare-earth elements using an X-ray fluorescence spectrometer...

A method for direct determination of cadmium, chromium, copper and lead in sediments and soil samples by electrothermal atomic absorption spectrometry using Zr, Ir, etylenediamine acetic acid (EDTA), Zr + EDTA, Ir + EDTA, Zr + Ir and Zr + Ir + EDTA as chemical modifiers in 0.5% (v/v) Triton X-100 plus 0.2% (v/v) nitric acid mixture used as diluent was developed. The effects of mass and mass rat...

The present investigation aimed at the determination of Cr addition on microstructure, phase composition, and mechanical properties Al-Cu-Y-Zr alloy. Quasi-binary alloys ternary Al-Cu-Y system with atomic rotation Cu/Y = 4/1 have a narrow solidification range high solidus temperature. 0.3% in Al-5.1Cu-1.7Y-0.3Zr alloy provides formation novel quaternary Al81–85Cu7–10Y3–4Cr5 phase. L12-Al3(Zr,Y)...

The title compound, [CrZr(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)], consists of two metal centres, with a (penta-carbonyl-chromium)oxymethyl-carbene group coordinating as a monodentate ligand to the zirconocene chloride. π-Delocalization through the Zr-O-C=Cr unit is indicated by a short Zr-O distance [2.041 (3) Å] and a nearly linear Zr-O-C angle [170.5 (3)°]. Mol-ecules are aligned with their mol-ec...

The microstructure of a Cu-0.1%Cr-0.1%Zr alloy after annealing or aging and equal channel angular pressing with conform (ECAP-C) process was investigated. ECAP-C led to formation strain induced low-angle boundaries (LAB) which transformed in high-angle (HAB) during deformation. Deformation microbands developed 1 pass, leading new ultrafine grain the upon further processing. Average size gradual...

A new approach to the synthesis of highly stable aqueous colloids of coordination polymer nanoparticles was developed by using water-soluble chitosan beads as template and as stabilizing agent. The method consists in the synthesis of nanocomposite beads containing cyano-bridged coordination polymer nanoparticles via step-by-step coordination of the metal ions and the hexacyanometallate precurso...

Ternary intermetallic A–B–C systems sometimes have unexpected behaviors. The present paper examines situations in which there is a tendency to simultaneously form the compounds ABx, ACx and BCx with the same crystal structure. This causes irregular shapes of the phase homogeneity domains and, from a structural point of view, a complete reversal of site occupancies for the B atom when crossing t...
