Micro/mesoporous conducting carbonized polyaniline 5-sulfosalicylate nanorods/nanotubes: Synthesis, characterization and electrocatalysis
(Elsevier Science Sa, Lausanne, 2011)
Micro/mesoporous conducting nitrogen-containing carbon nanorods/nanotubes with high surface area, and excellent electrocatalytic activity for the oxygen reduction reaction, were synthesized by the carbonization of ...
Kinetics and mechanism of structural transformations of Fe75Ni2Si8B13C2 amorphous alloy induced by thermal treatment
(Elsevier, 2011)
The kinetics of structural transformations of the Fe75Ni2Si8B13C2 amorphous alloy under non-isothermal conditions was studied. It was shown that the amorphous alloy was stable up to 723 K, when multi-step structural ...
Experimental investigation and thermodynamic prediction of the Ni-Pb-Sb phase diagram
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
The phase diagram of the ternary Ni-Pb-Sb system was investigated experimentally by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS) methods, and ...
Electrochemical synthesis and corrosion behavior of polyaniline-benzoate coating on copper
(Elsevier Science Sa, Lausanne, 2011)
Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25 mA cm(-2), from aqueous solution of 0.3 mol dm(-3) sodium ...
Annulations of isoquinoline and beta-carboline ring systems: synthesis of 8-oxoprotoberberine derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Annulation processes of isoquinoline and p-carboline compounds have been investigated leading to synthetic routes for the preparation of 8-oxoprotoberberine derivatives. The key steps combined a diene formation/Diels-Alder ...
Negative Refractive Index Metasurfaces for Enhanced Biosensing
(MDPI, 2011)
In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties ...
Cold-Pressed Pumpkin Seed Oil Antioxidant Activity as Determined by a DC Polarographic Assay Based on Hydrogen Peroxide Scavenge
(Springer, New York, 2011)
Antioxidant (AO) activity of cold pressed pumpkin (Cucurbita pepo L.) seed oil, produced from three naked and one hulled variety, was assessed using a DC polarographic assay based on a hydrogen peroxide scavenge (HPS). ...
Synthesis and Characterization of Novel Urethane-Siloxane Copolymers with a High Content of PCL-PDMS-PCL Segments
(Wiley-Blackwell, Malden, 2011)
Novel polyurethane copolymers derived from 4,4'-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BD) and alpha, omega-dihydroxy-[poly(caprolactone)-poly (dimethylsiloxane)-poly(caprolactone)] (a, x-dihydroxy( ...
Isolation and identification of phenolic compounds from Hypericum richeri Vill. and their antioxidant capacity
(Taylor & Francis Ltd, Abingdon, 2011)
The chemical composition and free radical scavenging properties of the MeOH extract of Hypericum richeri and its subsequent CHCl3, n-BuOH, EtOAc and aqueous extracts were investigated. Four quercetin-3-O-glycosides, three ...
Assessment of the pseudo total metal content in alluvial sediments from Danube River, Serbia
(Springer, New York, 2011)
We used elemental carbon, nitrogen, hydrogen and sulfur as well as ratios of hydrogen and nitrogen with total organic carbon for investigation of source and conditions of organic matter in alluvial Danube sediments. We ...
