Robust electronic and transport properties of graphene break nanojunctions
(Amer Physical Soc, College Pk, 2011)
We report a systematic research on structural, electronic, and transport properties of a variety of graphene nanoribbon (GNR) break junctions, with different widths and edge chiralities. Our extensive molecular dynamics ...
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 ...
Structural organisation of the wood polymers in the wood fibre structure
(China Light Industry Press, Beijing, 2011)
The organisation of the major polymers in the wood fibre structure has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, the structure providing ...
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, ...
