Influence of the storage on bioactive compounds and sensory attributes of herbal liqueur
(Inst Materials Physics, Bucharest, 2012)
Stability of bioactive compounds present in a herbal liqueur, as well as its sensory attributes were surveyed during a year - long storage under various conditions. The antioxidant activity, the total content of phenolic ...
Chemical Profile, Radical Scavenging and Cytotoxic Activity of Yellow Gentian Leaves (Genitaneae luteae folium) Grown in Northern Regions of Montenegro
(Natural Products Inc, Westerville, 2012)
LC-ESI-MS and HPLC were used for the identification of the constituents from G. lutea leaves collected at different localities, as well as for quantification of the main compounds. Seven secoiridoids, five C-glucoflavones ...
Oxidative 10-membered ring expansion and contraction of stereoisomeric 1(10)-unsaturated and 1,10-epoxy-5-oxo-5,10-secosteroids induced by peracids
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The present study is concerned with the oxidative behaviour of unsaturated and epoxy 5-oxo-5,10-secosteroids in the presence of m-CPBA or TFAA-UHP as oxidants in order to investigate potential parameters controlling the ...
Formation of two-dimensional (2D) lead dendrites by application of different regimes of electrolysis
(Springer, New York, 2012)
Electrodeposition of lead from nitrate electrolyte in constant regimes of electrolysis was analyzed and the obtained powder lead deposits were examined by scanning electron microscopy. Polarization curve for lead ...
New androst-4-en-17-spiro-1,3,2-oxathiaphospholanes. Synthesis, assignment of absolute configuration and in vitro cytotoxic and antimicrobial activities
(Elsevier Science Inc, New York, 2012)
The reactions of 17 alpha-hydroxyprogesterone with Lawesson's reagent (LR) in toluene, CH2Cl2 and/or CCl4 gave, depending on the duration of the reaction, two diastereoisomeric androst-4-en-17-spiro-1,3,2-oxathiaphosphol ...
Carbon monoxide electrooxidation on Pt and PtRu modified zeolite X
(Springer, Dordrecht, 2012)
Zeolite NaX was modified by Pt and Pt/Ru nanodispersed metallic clusters. This modification was achieved by zeolite impregnation with acetylacetonate salt/acetone solution, followed by acetone evaporation and thermal ...
Dynamic Mechanical Behaviour of Polymer Bonded Nd-Fe-B Composite Materials
(Japan Inst Metals, Sendai, 2012)
Magnetic composite materials with varied content of Nd-Fe-B particles in epoxy matrix are examined from a dynamic mechanical perspective. Structural, viscoelastic and magnetic properties of composites have been observed ...
The application of zeolite nanopowder for the construction of the dense composite polymer membranes for carbon dioxide separation
(Inst Materials Physics, Bucharest, 2012)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Magnetic couplings mediated through the non-covalent interactions
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Density functional theory (DFT), broken symmetry (BS) approach, was applied in order to determine the mechanism of couplings through the non-covalent interactions for the series of coordination compounds bridged by strong ...
Modeling interactions of α1a adrenergic receptor and different arylpiperazine ligands
(Inst Materials Physics, Bucharest, 2012)
Molecular modelling studies were undertaken in order to identify key interactions of selected ligands with α1A adrenergic receptor, responsible for their binding and presumably receptor activation. The previously made model ...
