Cu(InGa)(SeS)2 thin films have been prepared using multi source thermal co-evaporation. The incorporation of the volatile chalcogen species Se and S into the films depends on the fluxes of the evaporated species during growth and the relative [Cu]/[In+Ga] and [Ga]/[In+Ga] compositions. The dependence of the relative Se and S incorporation in Cu(InGa)(SeS)2 on the substrate temperature is charac...

Three experiments were conducted to study Cu sulfate and tribasic Cu chloride (TBCC) as sources of supplemental Cu for poultry. In Experiment 1, 252 chicks were fed the basal corn-soybean meal diet (26 ppm Cu) supplemented with either 0, 150, 300, or 450 ppm Cu from Cu sulfate or TBCC for 21 d. Chicks fed 450 ppm Cu from sulfate had lower (P < 0.05) feed intake than those consuming other diets....

The ability of the flavan kazinol Q (KQ) to induce DNA breakage in the presence of Cu(II) was examined by agarose gel electrophoresis using supercoiled plasmid DNA. In KQ-mediated DNA breakage reaction, the involvement of reactive oxygen species (ROS), H(2)O(2) and O(2)- was established by the inhibition of DNA breakage by catalase and revealed DNA breakage by superoxide dismutase (SOD). The ce...

The joining of lead-free Sn-3.0Ag-0.5Cu (SAC305) solder alloy to metal substrate with the addition of a porous Cu interlayer was investigated. Two types of porous Cu interlayers, namely 15 ppi—pore per inch (P15) and 25 ppi (P25) were sandwiched in between SAC305/Cu substrate. The soldering process was carried out at soldering time of 60, 180, and 300 s at three temperature levels of 267, 287, ...

A novel transition metal polyoxotungstate, [Cu(H2O)6][{Cu(H2O)2}2{Cu(H2O)4H4W12O42}] · 12H2O (1), has been synthesized in aqueous solution and characterized by single-crystal X-ray diffraction, elemental analysis, IR and UV/vis spectroscopy, and TG analysis. The paradodecatungstate anions [H2W12O42]10− are linked by CuO6 octahedra, forming a three-dimensional (3D) structure. The magnetic suscep...

We present the results of temperature-dependent self-assembly of dicarbonitrile-pentaphenyl molecules (NC-Ph5-CN) on Cu(111). Our low-temperature scanning tunneling microscopy study reveals the formation of metal-organic and purely organic structures, depending on the substrate temperature during deposition (160-300 K), which determines the availability of Cu adatoms at the surface. We use tip ...

The tungsten piperidylhydrazido complex Cl4 CH3CN W N-pip 1 was used for film growth of tungsten carbonitride WNxCy by metal-organic chemical vapor deposition CVD in the absence and presence of ammonia NH3 in H2 carrier. The microstructure of films deposited with NH3 was x-ray amorphous between 300 and 450 °C. The chemical composition of films deposited with NH3 exhibited increased N levels and...

Twenty-seven patients receiving a standard cytosine arabinoside and daunorubicin regimen as induction of reinduction therapy of acute myelogenous leukemia were randomly assigned to receive lithium carbonate, 300 mg t.i.d., or no lithium. Treatment groups were comparable with respect to age and baseline granulocyte counts. All patients developed granulocyte nadirs below 100/cu mm. By actuarial a...

Inelastic neutron scattering spectra were measured with a time-of-flight spectrometer on six disordered Cu-Au alloys at 300 K. The neutron-weighted phonon density of states was obtained from a conventional analysis of these spectra. Several methods were developed to account for this neutron weighting and obtain the phonon entropy of the disordered alloys. The phonon entropies of formation of di...
