Far infrared study of impurity local modes in Pr doped PbTe
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of lead telluride doped with Pr were produced using the Bridgman method. Far infrared spectra of the samples doped with 0.15 at%, 0.25 at% and 0.6 at% Pr are presented. The experimental data were ...
Fabrication of proton conducting solid oxide fuel cell by using electrophoretic deposition
(ECS Transactions, 2009)
Anode-supported proton conducting solid oxide fuel cells (SOFCs) were fabricated by using electrophoretic deposition (EPD) for the electrolyte film deposition. BaCe0.9Y0.1O3-δ (BCY10) thick films were deposited on NiO-BCY10 ...
Synthesis and characterization of ceria based nanometric powders
(Elsevier Science Bv, Amsterdam, 2009)
Nanopowdered solid solution Ce(1-x)Fe(x)O(2-delta) samples (0 lt = x lt = 0.1) were synthesized by a self-propagating room temperature synthesis (SPRT). XRD and Raman spectroscopy at room temperature were used to study ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
Far infrared properties of sintered Pb0.9Sn0.1Te doped with palladium
(Springer, New York, 2009)
Far infrared reflectivity spectra of sintered Pb0.9Sn0.1Te doped with 0.2 and 2 at.% Pd are measured. The experimental results are analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. ...
Far infrared study of some rare earth impurities crystals of Pb1-xSnx alloys
(National Institute of Optoelectronics, 2009)
Single crystal samples of Pb0.9Sn0.1Te doped with Yb, Sm or Gd were produced using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for highly polished samples with various impurity ...
Electrophoretic deposition of dense BaCe0.9Y0.1O3-x electrolyte thick-films on Ni-based anodes for intermediate temperature solid oxide fuel cells
(Elsevier, Amsterdam, 2009)
Proton conducting BaCe0.9Y0.1O3-x (BCY10) thick films are deposited on cermet anodes made of nickel-yttrium doped barium cerate using electrophoretic deposition (EPD) technique. BCY10 powders are prepared by the citrate-nitrate ...
Improved total conductivity of nanometric samaria-doped ceria powders sintered with molten LiNO3 additive
(Elsevier, Amsterdam, 2009)
Nanometric 20% molar Sm-doped ceria (SDC20) powders were synthesized by co-precipitation in the presence of N, N, N', N' tetramethylethylendiamine (TMEDA). SDC20 powders were sintered using lithium nitrate salt in various ...
Decline in the Index of Biotic Integrity of the Fish Assemblage as a Response to Reservoir Aging
(Springer, Dordrecht, 2009)
The fish assemblage from reservoir Medjuvrsje was monitored over the 1955-2000 period. The Medjuvrsje Reservoir is one of the oldest Serbian reservoirs formed in 1953. Ichthyofauna was sampled in 1955, 1984, 1991 and 2000. ...
Generation of Hydroxyl Radical in Isolated Pea Root Cell Wall, and the Role of Cell Wall-Bound Peroxidase, Mn-SOD and Phenolics in Their Production
(Oxford Univ Press, Oxford, 2009)
The hydroxyl radical produced in the apoplast has been demonstrated to facilitate cell wall loosening during cell elongation. Cell wall-bound peroxidases (PODs) have been implicated in hydroxyl radical formation. For this ...
