Preparation, sintering and electrical properties of nano-grained multidoped ceria
(Elsevier Sci Ltd, Oxford, 2010)
Multiply doped ceria nanopowders were synthesized by applying MGNP (modified glycine/nitrate procedure). The overall concentration of dopants was kept constant (x = 0.2) whereby Gd ion as the main dopant was gradually ...
Anisotropy of the in-plane angular magnetoresistance of electron-doped Sr1-xLaxCuO2 thin films
(Amer Physical Soc, College Pk, 2010)
Signatures of antiferromagnetism (AF) in the underdoped Ln(2-x)Ce(x)CuO(4) (Ln=Nd, Pr, ...) family are observed even for doping levels for which superconductivity exists. We have looked for a similar property in a different ...
Characterisation of phenol oxidase and peroxidase from maize silk
(Wiley-Blackwell, Hoboken, 2010)
Silk of some maize genotypes contains a high level of phenolics that undergo enzymatic oxidation to form quinones, which condense among themselves or with proteins to form brown pigments. Two phenolic oxidizing enzymes, ...
Properties of lanthanum doped BaTiO3 produced from nanopowders
(Elsevier Sci Ltd, Oxford, 2010)
Pure and barium titanate (BT) powders doped with different lanthanum concentration were prepared by the polymeric precursor method (Pechini process) which was carried out as a three-stage process from organometallic ...
Penetration depth of electron-doped infinite-layer Sr0.88La0.12CuO2+x thin films
(Amer Physical Soc, College Pk, 2010)
The in-plane penetration depth of Sr0.88La0.12CuO2+x thin films at various doping obtained from oxygen reduction has been measured, using ac-susceptibility measurements. For the higher doping samples, the superfluid density ...
The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
Effect of parameters of square-wave pulsating current on copper electrodeposition in the hydrogen co-deposition range
(Elsevier Science Inc, New York, 2010)
Copper electrodeposition processes in the hydrogen co-deposition range by the pulsating current (PC) regime were examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
