Temperature dependence of the kinetics of oxygen reduction on carbon-supported Pt nanoparticles
(Srpsko hemijsko društvo, Beograd, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryogel. The specific surface area of the support was 5 17 m(2) g(-1), the Pt particles ...
Deconvolution of lignin fluorescence spectra: A contribution to the comparative structural studies of lignins
(Maik Nauka/Interperiodica/Springer, New York, 2007)
In this work, we deconvoluted the fluorescence spectra of lignin and a lignin model compound using a combination of one symmetric ( Gaussian) and the most appropriate number of asymmetric (Log-normal) models. We aimed to ...
Flavonoids from the aerial parts of Onobrychis montana subsp scardica
(Srpsko hemijsko društvo, Beograd, 2008)
Rutin (1, main constituent) and two flavone C-glycosides, vitexin (2) and vitexin 2 ''-O-alpha-rhamnopyranoside (3) were isolated from the aerial parts of Onobrychis montana subsp. scardica. They were identified by H-1-NMR, ...
New Antitumour Natural Products from Marine Red Algae: Covering the Period from 2003 to 2012
(Bentham Science Publ Ltd, Sharjah, 2015)
This review covers the 2003-2012 literature data published for natural products originating from marine red algae. The focus is on new antitumour substances, together with details related to the organism sourced. It ...
Morphology and composition of the Fe-Ni powders electrodeposited from citrate containing electrolytes
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposition of the Fe-Ni powders from citrate containing electrolytes for different Ni/Fe ions concentration ratios, using Fe(Ill) and Fe(II) salts at pH 4.5 and pH 4.0 respectively was investigated by the ...
New Route for Stabilization of 1T-WS2 and MoS2 Phases
(Amer Chemical Soc, Washington, 2011)
The phenomenon of a partial 2H -> 1T phase transition within multiwalled WS2 nanotubes under substitutional rhenium doping is discovered by means of high-resolution transmission electron microscopy. Using density-functional ...
The content of antioxidants in sunflower seed and kernel
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
The primary objective of this research was to determine differences among investigated sunflower genotypes and whether the analysed hybrids could be sources of phenols and tocopherols important for storage stability of ...
Engineering carbon chains from mechanically stretched graphene-based materials
(Amer Physical Soc, College Pk, 2011)
The electrical response of graphene-based materials can be tailored under mechanical stress. We report different switching behaviors that take place in mechanically deformed graphene nanoribbons prior to the breakage of ...
Optical properties of PbTe doped with Nd
(Springer, New York, 2010)
Single crystals of lead telluride doped with Nd were synthesized using the Bridgeman method. Room temperature far infrared reflectivity spectra were measured for PbTe samples with Nd content in the range 0.2-0.9 at.%. ...
Robust electronic and transport properties of graphene break nanojunctions
(Amer Physical Soc, College Pk, 2011)
We report a systematic research on structural, electronic, and transport properties of a variety of graphene nanoribbon (GNR) break junctions, with different widths and edge chiralities. Our extensive molecular dynamics ...
