Does the pelletization pressure modify the effective anisotropy of the grains in (Bi,Pb)2223 bulk system? Abstract: In this paper we present a new method to determine separately inter and intragranular magnitudes of polycrystalline superconducting materials, […]
Non-ohmic properties of CaCu3Ti4O12 thin films deposited By RF-sputtering Abstract: Calcium copper titanate (CaCu3Ti4O12, CCTO), thin films with polycrystalline nature have been deposited by RF sputtering on Pt/Ti/SiO2/Si (100) substrates at a room temperature followed by […]
Nb-Doped TiO2 Photocatalysts Used to Reduction of CO2 to Methanol Abstract: In pursuit of higher photoactivity, Nb-doped TiO2 powders were evaluated in the reduction of CO2. The replacement of Ti by Nb in the crystalline structure […]
Voltage relaxation and Abrikosov-Josephson vortices in Bi-2223 superconductors doped with alpha-Al2O3 nanoparticles Abstract: We have observed a change in the behaviour of voltage-relaxation curves with remnant magnetic flux, when the maximum magnetic field applied before starting […]
Microstructural and electrical transport properties of uniaxially pressed ceramic superconductors Abstract: We have studied the effect of the pelletization pressure on microstructural and electrical transport properties of superconducting ceramics with starting composition given by the formula […]
Experimental and theoretical study of the energetic, morphological, and photoluminescence properties of CaZrO3:Eu3+ Abstract: In this study, we present a combined experimental and theoretical study of the geometry, electronic structure, morphology, and photoluminescence properties of CaZrO3:Eu3+ […]
Structural, morphological and optical investigation of beta-Ag2MoO4 microcrystals obtained with different polar solvents Abstract: This communication reports the formation of beta-silver molybdate (beta-Ag2MoO4) microcrystals synthesized by a simple precipitation method using different polar solvents (water, methanol, […]
A large red-shift in the photoluminescence emission of Mg1-xSrxTiO3 Abstract: In this letter, we report a detailed study of the influence of the synthesis and the optical properties of Sr-doped MgTO3 powders synthesized via a polymeric […]
