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 ...
Petrological, organic geochemical and geochemical characteristics of coal from the Soko mine, Serbia
(Elsevier, 2008)
A petrological, organic geochemical and geochemical study was performed on coal samples from the Soko Mine, Soko Banja basin, Serbia. Ten coal and two carbonaceous clay samples were collected from fresh, working faces in ...
Study of the kinetics and influence of Bi_irr on formic acid oxidation at Pt2Ru3/C
(Elsevier, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HClO4 solutions was examined on thin film Pt2Ru3/C electrode. XRD pattern revealed that Pt2Ru3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
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) ...
Contribution of marine and continental aerosols to the content of major ions in the precipitation of the central Mediterranean
(Elsevier, 2006)
The region of the investigated receptor is situated in the southern part of the Adriatic Sea in the Mediterranean. The measuring station is located on the seashore, which, being considered as a border area, is representative ...
Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis
(Royal Society of Chemistry, 2008)
Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. ...
Thermal Properties of PMMA/TiO2 Nanocomposites Prepared by In-Situ Bulk Polymerization
(Wiley, 2009)
The surface of anatase TiO2 nanoparticles, obtained by
the controlled hydrolysis of titanium tetrachloride, was
modified by 6-palmitate ascorbic acid. The surface
modified TiO2 nanoparticles were dispersed in ...
Ballistic magnetoresistance versus magnetostriction effects in electrodeposited nanocontacts at room temperature
(Institute of Electrical and Electronics Engineers, Inc., 2003)
The authors present experiments and discuss recent results on ballistic magnetotesistance in nanometer size (on the order of 1 to 10 nm) nanocontacts grown by electrodeposition in
thin wires and in thin films of a few ...
Far Infrared Reflectivity Properties of BaTiO3 Ceramics
(Carl Hanser Verlag, 2001)
Far-infrared and infrared reflectivity measurements have been made on pure BaTiO3, BaTiO3 doped with 5 mol% LiF and (Ba,Ca,Pb)TiO3 at room temperature in the range between 50 and 1000 cm–1. A fitting procedure, based on a ...
Obtention of selective membranes for water and hydrophobic liquids by plasma enhanced chemical vapor deposition on porous substrates
(Elsevier, 2004)
In this work, the possibility of obtaining selective membranes for water and hydrophobic liquids by plasma enhanced chemical vapor deposition (PECVD) of hexamethyldisilazane (HMDS) or double layers of HMDS and n-hexane on ...
