Isolation and Biological Evaluation of Jatrophane Diterpenoids from Euphorbia dendroides
(American Chemical Society (ACS), 2011)
From the Montenegrin spurge Euphorbia dendroides, seven new diterpenoids [jatrophanes (1-6) and a tigliane (7)] were isolated and their structures elucidated by spectroscopic techniques. The biological activity of the new ...
New anti-cancer characteristics of jatrophane diterpenes from Euphorbia dendroides
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Jatrophane diterpenes were shown to be inhibitors of P-glycoprotein (P-gp). There are also evidences on their microtubule-interacting activity in cancer cells. We evaluated new anti-cancer characteristics of two jatrophane ...
Treatment of the Multimode Jahn-Teller Problem in Small Aromatic Radicals
(American Chemical Society (ACS), 2011)
The family of the Jahn-Teller (JT) active hydrocarbon rings, CH (n = 5-7), was analyzed by the means of multideterminantal density functional theory (DFT) approach. The multimode problem was addressed using the intrinsic ...
Ethylenediamine-modified multiwall carbon nanotubes as a Pt catalyst support
(Elsevier Science Sa, Lausanne, 2011)
Multi-walled carbon nanotubes (MWCNTs) were used as a support for Pt nanoparticles prepared by the microwave-assisted polyol method. The MWCNTs were pretreated by chemical oxidation (o-MWCNTs) followed by modification by ...
Kinetic investigations of the electrochemical bromination of peracetylated D-glucal in organic solvents
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Cyclic voltammetry and ultramicroelectrodes were used to investigate the kinetic aspects of the electrochemical bromination of 3,4,6-tri-O-acetyl-D-glucal (1) in acetonitrile (AN), dichloromethane (DCM), and dimethylsulfoxide ...
Structures of chaos in open reaction systems
(Royal Soc Chemistry, Cambridge, 2011)
By numerically simulating the Bray-Liebhafsky (BL) reaction (the hydrogen peroxide decomposition in the presence of hydrogen and iodate ions) in a continuously fed well stirred tank reactor (CSTR), we find "structured" ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
Organic geochemistry of Miocene source rocks from the Banat Depression (SE Pannonian Basin, Serbia)
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
The origin, depositional environment and maturity of petroleum source rocks were determined via conventional whole rock and biomarker analysis of samples from wells in the Banat Depression, where the most important Serbian ...
Bench-to-bedside review: Sepsis - from the redox point of view
(Biomed Central Ltd, London, 2011)
The pathogenesis of sepsis and its progression to multiple organ dysfunction syndrome and septic shock have been the subject of investigations for nearly half a century. Controversies still exist with regard to understanding ...
Aliphatic biomarkers and their signal from two hydrogeochemically differing sedimentary environments of the Tertiary Krepoljin Coal Basin (Serbia)
(Springer, New York, 2011)
The sediments of the coal-bearing series of the Tertiary Krepoljin Brown Coal Basin have been investigated and presented in this manuscript. The samples of the intercalated mixed sediments (pieces of coal in clays, sandstones ...
