Studies on electrochemical oxidation of azithromycin and Hemomycin (R) at gold electrode in neutral electrolyte
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the ...
Nanofabrication of negative refractive index metasurfaces
(Elsevier, 2006)
We designed and fabricated planar metamaterial ‘particles’ (metasurfaces) intended to achieve negative effective refractive index in mid-infrared. We considered double split ring resonators (negative permeability particles) ...
Activity of a PtBi alloy in the electrochemical oxidation of formic acid
(Elsevier, 2006)
Formic acid oxidation in acid solution was examined on a PtBi alloy characterized by X-ray photoelectron spectroscopy. Three chemical states of Bi, i.e., PtBi or Bi(0), Bi2O3 and BiO(OH) were found. Electrochemical ...
Variable energy gap of SiCN nanopowders
(Springer, 2006)
SiCN and SiC nanopowders were prepared by infrared laser pyrolysis of gaseous precursors starting from a SiH4C2H2NH3 gas mixture. The SiCN powders were composed of an amorphous phase ascribed to the ternary compound with ...
Thermal degradation of aliphatic hyperbranched polyesters and their derivatives
(Elsevier, 2006)
In this study results of thermal degradation of aliphatic hyperbranched polyesters, AHBP, and their derivatives, determined by non-isothermal thermogravimetric analysis in inert atmosphere (N2) are presented. The thermal ...
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 ...
