Mechanical and Microstructural Changes of Alkali-Activated Binder Due to the Leaching Process
(Ministerio de Ciencia e Innovacion, Spain & Instituto Eduardo Torroja, 2011)
This paper investigates the resistance of alkali-activated binder to leaching. This type of binder was obtained by alkali-activation of blast-furnace slag. The slag was activated by aqueous solution of sodium silicate. The ...
The Negative Effect of Soy Extract on Erythrocyte Membrane Fluidity: An Electron Paramagnetic Resonance Study
(Springer, New York, 2011)
A decrease of erythrocyte membrane fluidity can contribute to the pathophysiology of hypertension. Soy products, which are used as alternative therapeutics in some cardiovascular conditions, contain various isoflavones ...
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 ...
Structural and magnetic properties of nanocrystalline bismuth manganite obtained by mechanochemical synthesis
(Springer, Dordrecht, 2011)
We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the ...
Optimization of electrolytic process of formation of open and porous copper electrodes by the pulsating current (PC) regime
(Elsevier Science Sa, Lausanne, 2011)
Optimization of process of formation of open and porous copper electrodes, denoted as the honeycomb-like ones, by the regime of pulsating current (PC) is considered. The square-waves PC were consisted of the same amplitude ...
A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Srpsko hemijsko društvo, Beograd, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 lt delta ...
Influence of the ratio between Ni and BaCe0 9Y0 1O3-delta on microstructural and electrical properties of proton conducting Ni-BaCe0 Y-9(0) O-1(3-delta) anodes
(Elsevier Science Sa, Lausanne, 2011)
Cermet anode substrates Ni-BaCe0 9Y0 1O3-delta (Ni-BCY10) with varied ratios between Ni and BCY10 were prepared BCY10 powders were prepared by the citrate-nitrate auto-combustion method and anode substrates were prepared ...
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 ...
