Electrical properties of lanthanum doped barium titanate ceramics
(Elsevier Science Inc, New York, 2011)
Pure and lanthanum doped barium titanate (BT) ceramics were prepared by sintering pellets at 1300 degrees C for 8 h, obtained from nanopowders synthesized by the polymeric precursor method. XRD results showed formation of ...
A Polarographic Study of Chlorogenic Acid and Its Interaction with Some Heavy Metal Ions
(Wiley-Blackwell, Malden, 2011)
The behavior of chlorogenic acid (CGA) and its interaction with Hg(II), Pb(II), Cu(II), Cd(II) and Zn(II) has been studied using direct current (DC) and differential-pulse polarography (DPP). Adsorptive and kinetic/catalytic ...
A Comparative Assessment of the Potential of Polysaccharide Production and Intracellular Sugar Composition within Lingzhi or Reishi Medicinal Mushroom, Ganoderma lucidum (W.Curt.:Fr.)P. Karst. (Aphyllophoromycetideae)
(Begell House Inc, Danbury, 2011)
Ganoderma lucidum is a well-known medicinal mushroom species in which polysaccharides are one of the major sources of biological activity. The species was considered as a species-complex due to significant variations in ...
Defect induced variation in vibrational and optoelectronic properties of nanocrystalline ZnO powders
(Amer Inst Physics, Melville, 2011)
Structural disorder of ZnO nanopowders with mean crystallite size down to 15 nm, produced by mechanical activation in high energy mills, has been analyzed by x-ray diffraction and Raman spectroscopy. The influence of such ...
Antioxidant activity of small grain cereals caused by phenolics and lipid soluble antioxidants
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
In this study, the content of soluble, free forms of phenolic compounds (total phenolics, flavonoids, PVPP (polyvinylpolypyrrolidone) bound phenolics, proanthocyanidins and phenolic acids), as well as the content of ...
Hydrogen storage properties of MgH2 mechanically milled with alpha and beta SiC
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
To understand the influence of various crystallographic phases on hydrogen storage properties, ball milling of MgH2 with hexagonal (alpha) and cubic (beta) SiC have been performed. Structural characterization of all samples ...
Bio-activities of extracts from some axenically farmed and naturally grown bryophytes
(Academic Journals, Victoria Island, 2011)
The antifungal activity of dimethyl sulfoxide (DMSO) extracts of three bryophyte species, two mosses (Atrichum undulatum (Hedw.) P. Beauv., Physcomitrella patens (Hedw.) Bruch and Schimp) and a liverwort (Marchantia ...
Chemical and antioxidant properties of cultivated and wild fragaria and rubus berries
(Wiley-Hindawi, London, 2011)
Content of individual sugars, organic acids, total phenolics (TPH), some important phenolic compounds (kaempferol, myricetin, quercetin, and ellagic acid) and total antioxidant capacity (TAC) in the fruits of strawberry, ...
Insight into Danube sturgeon life history: trace element assessment in pectoral fin rays
(Springer, New York, 2011)
Sturgeon populations in the Danube River have experienced severe decline during the last several decades, mostly due to the poorly regulated fishery, river fragmentation and water pollution. This study focuses on gaining ...
Independent complexity patterns in single neuron activity induced by static magnetic field
(Elsevier Ireland Ltd, Clare, 2011)
We applied a combination of fractal analysis and Independent Component Analysis (ICA) method to detect the sources of fractal complexity in snail Br neuron activity induced by static magnetic field of 2.7 mT. The fractal ...
