Chemical surface composition of the polyethylene implanted by Ag+ ions studied by phase imaging atomic force microscopy
(Elsevier, 2010)
High density polyethylene (HDPE) has been modified by Ag+ ion implantation with the energy of 60 keV. The total amount of implanted silver ions was 1, 5 and 12 x 10(15) ions/cm(2). The surface topography was observed by ...
Quantification of the lift height for magnetic force microscopy using 3D surface parameters
(Elsevier, 2010)
In this work, the quantitative conditions for the lift height for imaging of the magnetic field using magnetic force microscopy (MFM) were optimized. A thin cobalt film deposited on a monocrystalline silicon (1 0 0) substrate ...
Bromophilic substitution/carbophilic substitution cascade reactions of alpha,alpha-dibromo-2-methoxyacetophenone with C-, N- and O-nucleophiles
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
alpha,alpha-Dibromo-2-methoxyacetophenone reacts, under mild reaction conditions, with C-, N- and O-nucleophiles via a bromophilic substitution/protonation/carbophilic substitution cascade process to afford alpha-monosub ...
Thermal diffusivity of single crystal Bi0.9Sb0.1
(International Institute for the Science of Sintering, Beograd, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
Experimental study and thermodynamic remodeling of the Bi-Cu-Ni system
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
Phase equilibria in the Bi-Cu-Ni ternary system have been studied using differential thermal analysis (DTA) as well as by using the calculation of the phase diagram (CALPHAD) method. Literature experimental phase equilibria ...
The predicted infrared spectrum of the hyperberyllium molecule BeOBe in its (X)over-tilde(1)Sigma(+)(g) and (a)over-tilde(3)Sigma(+)(u) electronic states
(Academic Press Inc Elsevier Science, San Diego, 2010)
Hypermetallation is a concept that applies to molecules having metal stoichiometries that exceed normal valence, and BeOBe is just one example of such a molecule. Previous ab initio calculations and spectroscopic studies ...
Thionation of Some alpha,beta-Unsaturated Steroidal Ketones
(MDPI, 2010)
The reactions of selected alpha,beta-unsaturated steroidal ketones with Lawesson's reagent (LR) in CH(2)Cl(2) and toluene under the standard reaction conditions and with a combination of phosphorus pentasulfide with ...
A new triterpenoid saponin from the aerial parts of Cephalaria ambrosioides
(Taylor & Francis Ltd, Abingdon, 2010)
A new allose-containing triterpenoid saponin (1), along with a known saponin (2), were isolated from the aerial parts of Cephalaria ambrosioides. Their structures were determined by spectroscopic (2D-NMR and ESI-MS) methods. ...
Pruning effect on content of quercetin and catechin in berry skins of cv. Blaufrankisch (Vitis vinifera L.)
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2010)
The effect of pruning severity on quercetin and catechin content in berry skins of cv. Blaufrankisch (Vitis vinifera L.) was studied over 3 years. Different crop levels and canopy structures were obtained by retaining 8, ...
Cytotoxic and Cell Cycle Effects Induced by Two Herbal Extracts on Human Cervix Carcinoma and Human Breast Cancer Cell Lines
(Mary Ann Liebert Inc, New Rochelle, 2010)
In recent times interest has increased in the complementary medicine of cancer patients. Two herbal mixtures were prepared from 17 and 12 plants, respectively. The goal of this study was to examine the in vitro cytotoxic ...
