Isolation and identification of phenolic compounds from Hypericum richeri Vill. and their antioxidant capacity
(Taylor & Francis Ltd, Abingdon, 2011)
The chemical composition and free radical scavenging properties of the MeOH extract of Hypericum richeri and its subsequent CHCl3, n-BuOH, EtOAc and aqueous extracts were investigated. Four quercetin-3-O-glycosides, three ...
Correlation between structure, retention and activity of cholic acid derived cis-trans isomeric bis-steroidal tetraoxanes
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
Both quantitative structure-retention (QSRR) and quantitative structure-activity relationship (QSAR) studies have been performed to correlate the molecular characteristics of seven pairs of cis-trans isomeric bis-steroidal ...
Using the Low-Cost Waste Materials for Heavy Metals Removal from the Mine Wastewater
(Japan Inst Metals, Sendai, 2011)
The possibility of application of low-cost and easily available materials such as cardboard or sawdust for the heavy metals removal from the acid mine water was investigated. The sawdust was obtained from oak and fir-wood. ...
Synthesis and Characterization of Novel Urethane-Siloxane Copolymers with a High Content of PCL-PDMS-PCL Segments
(Wiley-Blackwell, Malden, 2011)
Novel polyurethane copolymers derived from 4,4'-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BD) and alpha, omega-dihydroxy-[poly(caprolactone)-poly (dimethylsiloxane)-poly(caprolactone)] (a, x-dihydroxy( ...
Changes of Hydrogen Peroxide and Radical-Scavenging Activity of Raspberry during Osmotic, Convective, and Freeze-Drying
(Wiley-Blackwell, Malden, 2011)
This study was conducted to investigate the influence of different drying treatments on antioxidant (AO) activity and phenolic content of raspberry (Rubus idaeus), cultivar Willamette. Whole raspberry fruits were dried ...
Annulations of isoquinoline and beta-carboline ring systems: synthesis of 8-oxoprotoberberine derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Annulation processes of isoquinoline and p-carboline compounds have been investigated leading to synthetic routes for the preparation of 8-oxoprotoberberine derivatives. The key steps combined a diene formation/Diels-Alder ...
Grand Canonical Monte Carlo study of argon adsorption in aluminium nanopores
(Taylor & Francis Ltd, Abingdon, 2011)
We present a theoretical study of argon adsorption on a model aluminium substrate structured with cylindrical nanopores. We employ state-of-the-art computational methods to obtain (i) accurate three-dimensional adsorption ...
Assessment of the pseudo total metal content in alluvial sediments from Danube River, Serbia
(Springer, New York, 2011)
We used elemental carbon, nitrogen, hydrogen and sulfur as well as ratios of hydrogen and nitrogen with total organic carbon for investigation of source and conditions of organic matter in alluvial Danube sediments. We ...
Micro/mesoporous conducting carbonized polyaniline 5-sulfosalicylate nanorods/nanotubes: Synthesis, characterization and electrocatalysis
(Elsevier Science Sa, Lausanne, 2011)
Micro/mesoporous conducting nitrogen-containing carbon nanorods/nanotubes with high surface area, and excellent electrocatalytic activity for the oxygen reduction reaction, were synthesized by the carbonization of ...
Structural diversification of the coordination mode of divalent metals with 1,3-propanediaminetetraacetate (1,3-pdta): The missing crystal structure of the s-block metal complex [Sr-2(1,3-pdta)(H2O)(6)]center dot H2O
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
This paper reports the synthesis and X-ray characteristics of the missing homonuclear s-block metal complex {[Sr-2(1,3-pdta)(H2O)(6)]center dot H2O}(n). In the title compound, the hexadentate 1,3-propanediaminetetraacetate ...
