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, […]
Rietveld refinement, cluster modelling, growth mechanism and photoluminescence properties of CaWO4:Eu3+ microcrystals Abstract: CaWO4:Eu3+ microcrystals (with 0, 1, 2 and 4 mol% Eu3+) were synthesized by a co-precipitation (CP) method and grown in a microwave-assisted hydrothermal […]
Rh(III)-catalyzed [5+1] oxidative cycloaddition of arylguanidines with alkynes: a novel access to C4-disubstituted 1,4-dihydroquinazolin-2-amines Abstract: Anovel and mild Rh-III-catalyzed [5+1] oxidative cycloaddition between arylguanidines and alkynes efficiently affords C4-disubstituted 1,4-dihydroquinazolin-2-amines. Members of this family of heterocycles, […]
Photoluminescence in NaNbO3 particles and films Abstract: In this work, we report the photoluminescence properties of NaNbO3 particles and films. The crystallization of NaNbO3 particles produced Na2NbO6.nH(2)O intermediate phase which was then converted to NaNbO3 following […]
Impact of the Alkali Cation on the Oscillatory Electro-Oxidation of Ethylene Glycol on Platinum Abstract: We report the effect of alkali cation (Li+, Na+, and K+) on the oscillatory electro-oxidation of ethylene glycol in alkaline media. […]
10 to 25-fold increase in the transport superconducting critical current density of spark-plasma sintered Bi-2223 superconductors Abstract: Pre-reacted powders of (Bi-Pb)(2)Sr2Ca2Cu3O10+delta (Bi-2223) were consolidated by using the spark plasma sintering (SPS) technique under vacuum and at […]
A comparison of charge-transfer mechanisms at rotated disk electrode for biomimetic binuclear and tetranuclear oxo-manganese complex in aqueous solution Abstract: Many high-valence multinuclear mu-oxo-bridged manganese complexes have been synthesized to mimic the active site of the […]
Degree of conversion of different composite resins photo-activated with light-emitting diode and argon ion laser Abstract: This study evaluated the degree of conversion (DC%) of one experimental and different brands of composite resins light-cured by two […]
Insights into electrodegradation mechanism of tebuconazole pesticide on Bi-doped PbO2 electrodes Abstract: The effect of the Bi doping of PbO2 coatings on the electrochemical degradation of the pesticide tebuconazole (TBC) was investigated. The insertion of 8% […]
Oscillatory Electro-oxidation of Methanol on Nanoarchitectured Pt-pc/Rh/Pt Metallic Multilayer Abstract: The oscillatory electro-oxidation of methanol was studied on polycrystalline Pt-pc and Pt-pc/Rh-2.0/Pt-1.0 metallic multilayers. The surfaces investigated consisted of 1.0 Pt outlayer surface deposited onto 2.0 […]
