Hydrogenation of soybean oil over Ag-Ni/diatomite catalysts. Effect of silver content on the cis/trans isomerization selectivity
(Materials Science Forum, 2006)
Silver promoted nickel catalysts supported on diatomite were prepared by precipitation method. Characterization of the catalysts prepared with different silver contents (0.1-4.0 wt%) included AAS, XRD, Hg porosimetry, BET ...
Infrared properties of sintered α-MnSe
(De Gruyter, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
Enhancement of the electrochemical reduction of oxygen at platinum by nickel underpotential deposition
(Springer Nature, 2006)
Polycrystalline Pt electrode was modified by underpotential deposition (upd) of nickel. The modification was performed by potential cycling in phosphate buffer pH7. 0 containing NiSO 4 , in which hydrogen and nickel upd ...
Cytotoxic constituents of Achillea clavennae from Montenegro
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Examination of the aerial parts of Achillea clavennae afforded eight guaianolides (1-8), three bisabolenes (9 11), four flavonols (12-15), sesamin (lignan) and isofraxidin (coumarin). The structures of the new compounds ...
Allozyme polymorphism of Mdh and alpha-Gpdh in Ixodes ricinus populations: comparison of borreliae-infected and uninfected ticks
(Springer, Dordrecht, 2006)
Ixodes ricinus Linnaeus (Acari: Ixodidae) ticks are vectors of numerous infectious diseases in humans and animals. The allozyme variability of MDH and alpha-Gpdh was detected by native polyacrylamide gel electrophoresis ...
The effect of hydrogen codeposition on the morphology of copper electrodeposits. 1. The concept of effective overpotential
(Elsevier, 2006)
The effect of hydrogen codeposition on the morphology of copper electrodeposits was studied. The dependences of the overall current and the volume of evolved hydrogen on the quantity of electricity used were plotted and ...
Magnetic field influence on silicon surface periodic structures obtained by plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
External magnetic field influence on silicon submicron surface periodic structures obtained by the action of nitrogen supersonic quasistationary compression plasma flow (CPF) is studied. CPF is generated by magnetoplasma ...
Systemic NF-kappaB activation in blood cells of breast cancer patients
(Maney Publishing, 2006)
There is a well-established role for reactive oxygen and nitrogen species, chronic inflammation and immune response in the pathogenesis of breast cancer. Complex interactions between breast cancer cells and surrounding ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
