One-step preparation of the BiVO4 film photoelectrode Abstract: A one-step method of preparing photoelectrochemically active nanostructured BiVO4 films is reported based on thermolysis (500 A degrees C in air) of a polyethylene glycol (PEG300) “paint-on” precursor […]
Synthesis of potassium niobates by the microwave-assisted solvothermal method Abstract: Potassium niobates have been synthesized by different methods, but few papers use the microwave-assisted solvothermal method, with possibility of a deeper evaluation in this area. In […]
Effect of selected herbicides on growth and lipid content of Nannochloris oculata Abstract: Nannochloris oculata (Droop) D.J. Hibberd has attracted attention as a potential source of biofuels because of high oil content and rapid growth rate. […]
Thermal treatment improvement of CuSbS2 absorbers Abstract: Thermal treatment in Sb2S3 vapor was used to improve the quality of CuSbS2 thin films, a promising non-toxic and earth-abundant absorber. A change in the CuSbS2 crystallographic texture and […]
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 […]
