“Vidas talhadas no avesso da história” é uma coletânea de estudos sobre o trabalho nos canaviais, organizada pelos sociólogos Maria Aparecida de Moraes e Silva e Lúcio Vasconcelos de Verçoza, que será lançada pela Editora […]
A Câmara Municipal de Araraquara aprovou por unanimidade nessa terça-feira (23) Projeto de Lei 097/2019, de autoria do vereador Jéferson Yashuda (PSDB), que denomina Rua Professor José Arana Varela a via pública da sede do […]
Toward a new generation of white phosphors for solid state lighting using glassy yttrium aluminoborates Abstract: We present a new family of highly emissive white phosphors. These phosphors are based on original glassy yttrium aluminoborates (g-YAB) […]
Local structure and photoluminescence properties of nanostructured Zn1-xMnxS material Abstract: Zinc sulfide (ZnS) pure or doped has received remarkable attention because of fundamental properties, versatility and potential for several technological applications as luminescent material. In this […]
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 […]
