Biomarker and micropetrographic investigations of coal from the Krepoljin Brown Coal Basin Serbia
(Elsevier, 2013)
We investigated early diagenetic processes of the extractable organic matter from the Miocene freshwater sequence, which consists of coal fragments in clays, sandstones and shales alternating with continuous brown coal ...
HCOOH oxidation on thin Pd layers on Au: Self-poisoning by the subsequent reaction of the reaction product
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
The oxidation of HCOOH has been investigated on thin Pd layers ranging from 1 to 17 ML equivalents electrodeposited on polycrystalline Au substrate (Pd"Au). The results are compared to those on Pd black. Potentiodynamic ...
The effect of rhodium nanoislands on the electrocatalytic activity of gold for oxygen reduction in perchloric acid solution
(Elsevier, 2013)
The effect of spontaneously deposited rhodium nanoislands on the electrocatalytic activity of polycrystalline gold, Au(poly), for oxygen reduction reaction (ORR) was studied using rotating disc electrode technique in 0.1 ...
The synthesis of single phase WC nanoparticles/C composite by solid state reaction involving nitrogen-rich carbonized polyaniline
(Elsevier Sci Ltd, Oxford, 2013)
Single phase tungsten carbide nanoparticles (WC-NPs), (mean particle diameter 5.4 nm), distributed over carbonized polyaniline (C-PANT) nanotubes/nanosheets were synthesized by a solid state reaction between WO3 and ...
Double Asymmetric Induction in Organocatalyzed Aldol Reactions: Total Synthesis of (+)-2-epi-Hyacinthacine A(2) and (-)-3-epi-Hyacinthacine A(1)
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
The stereodivergent synthesis of two hyacinthacine analogues, which relies on an organocatalyzed aldol addition, is described. The aldol addition of dioxanone to an -N-carbobenzyloxy-substituted chiral aldehyde, promoted ...
Jatrophane diterpenoids from the latex of Euphorbia dendroides and their anti-P-glycoprotein activity in human multi-drug resistant cancer cell lines
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Thirteen jatrophane diterpenoids (1-10, 13-15), three previously isolated (11, 12, 16) and a known tigliane (17) were isolated from the latex of Euphorbia dendroides. The structures and relative configurations of compounds ...
Butterfly scales as bionic templates for complex ordered nanophotonic materials: A pathway to biomimetic plasmonics
(Elsevier, 2013)
In this paper we propose a possible use of butterfly scales as templates for ordered 2D or 3D nanophotonic materials, with complexity not easily reproducible by conventional micro/nanofabrication methods. Functionalization ...
The Predicted Spectrum and Singlet-Triplet Interaction of the Hypermetallic Molecule SrOSr
(American Chemical Society (ACS), 2013)
In accordance with previous studies in our group on Be, Mg, and Ca hypermetallic oxides, we find that SrOSr has a linear (X) over tilde (1)Sigma(+)(g) ground electronic state and a very low lying first excited (a) over ...
Characterization of lead sorption by the natural and Fe(III)-modified zeolite
(Elsevier, 2013)
The influence of contact time, temperature and particle size on lead sorption by the natural and Fe(III)-modified zeolites was investigated. Characterization of the natural and Fe(III)-modified zeolite before and after ...
Effect of four lichen acids isolated from Hypogymnia physodes on viability of rat thymocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Four lichen acids, physodalic acid (F1), physodic acid (F2), 3-hydroxyphysodic acid (F3), and isophysodic acid (F4), were isolated from Hypogymnia physodes methanol extract using preparative reversed-phase high performance ...
