Kinetics of hexavalent chromium sorption on amino-functionalized macroporous glycidyl methacrylate copolymer
(Elsevier, 2009)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and functionalized ...
Melt Rheology of Aliphatic Hyperbranched Polyesters
(Wiley, 2009)
Rheological behavior in melt of aliphatic hyperbranched polyesters (AHBP), synthesized using pseudo-one-step and one-step procedure, was investigated in this work. Three commercially available AHBP were also examined. ...
Identification of Hot spots in Sm protein interfaces
(Belgrade, Serbia : Faculty of Chemistry, University of BelgradeGermany : Alexander von Humboldt Foundation, 2009)
This study aims to characterize the interface hot spot
residues of subunits in Sm proteins. We performed an analysis of the X ray structure of 15 Sm
motif containing proteins from the Protein Data Bank (PDB) and summarize ...
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 ...
The effects of nitric oxide (NO) and peroxynitrite on MnSOD (E.coli)
(Turkish Biochemical Society, 2003)
Our results demonstrate that MnSOD (E. coli)-stimulated generation of NO+ and NO- species is associated with nitration of enzyme tyrosine residues and dityrosinc formation, which cause enzyme inactivation. This represents ...
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 ...
The Diagenesis of Plant Lipids during the Formation of the Krepoljin Coal Basin (Serbia) - Using Multivariate Statistical Analysis in the Saturated Biomarkers
(Wiley-Blackwell Publishing, Inc, Malden, 2008)
The composition of the saturated hydrocarbon fraction of soluble organic matter (bitumen) from the Krepoljin brown coal basin (East Serbia) of Miocene age was investigated. The Krepoljin basin is especially interesting ...
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 ...
Examinations of cross-linked polyvinylpyridine in open reactor
(Materials Science Forum, 2005)
Macroporous cross-linked copolymer of 4-vinylpyridine and 25% (4:1) divinylbenzene is analyzed under open conditions, that is in a continuous well-stirred tank reactor (CSTR). With this aim the appropriate bifurcation ...
The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure / Uticaj prisustva alkohola u disperznoj sredini oksidnih solova ha osobine RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
