Particle growth during calcination of polycation oxides synthesized by the polymeric precursors method
The particle-growth kinetics of sodium niobate and zirconium titanate powders that were processed by the polymeric precursors method were studied. The growth kinetics that were studied for the particle, in the final stage ...
Al13[XMo/WOn] (X= Al, Co, V, P) composites as catalysts in clean oxidation of aromatic sulfides
(Elsevier Science, 2010-08-11)
Several phases of general formula Al13/[XMo6] (X= Al(III), Co(III), Cr(III), V(V) and Al13/P/[WO4]n) were prepared by combining the [AlO4Al12(OH)24(H2O)12]7+ (Al13) Keggin-type isopolycation with different iso or ...
Al13–[X–Mo/WOn] (X=Al, Co, V, P) composites as catalysts in clean oxidation of aromatic sulfides
(Elsevier Science, 2010-10-11)
Several phases of general formula Al13–[XMo6] (X = Al(III), Co(III), Cr(III), V(V) and Al13–P/[WO4]n) were prepared by combining the [AlO4Al12(OH)24(H2O)12]7+ (Al13) Keggin-type isopolycation with different iso or ...
High catalytic activity at low temperature in oxidative dehydrogenation of propane with Cr–Al pillared clay
(Elsevier Science Sa, 2013-10)
A montmorillonite was pillared separately with chromium and aluminum polyoxocations (Cr–C and Al–C respectively) and also with an equimolar mixture of both polioxocations (Al–Cr–C). The resulting solids were characterized ...
Enhancement of amperometric response to tryptophan by proton relay effect of chitosan adsorbed on glassy carbon electrode
(Elsevier Science Sa, 2014-11)
A simply prepared, low-cost, and sensitive electrochemically activated glassy carbon electrode (GCEa) modified with absorbed chitosan (CHIT) film for quantification of tryptophan (Trp) is reported. Combination of cyclic ...

XPS Analysis of Enzyme and Mediator at the Surface of a Layer-by-Layer Self-Assembled Wired Enzyme Electrode
(American Chemical Society, 2014-11)
High potential purified Trametes trogii laccase has been deposited in mono- and multilayer thin films on gold surfaces by layer-by-layer electrostatic adsorption self-assembly. The osmium bipyridil redox relay sites on ...
Platinum nanoparticles incorporated in silsesquioxane for use in LbL films for the simultaneous detection of dopamine and ascorbic acid
We describe the preparation of platinum nanoparticles (PtNPs) using the 3-n-propylpyridinium silsesquioxane chloride (SiPy+Cl-) as a nanoreactor and stabilizer. The formation of PtNPs was monitored by UV-Vis spectroscopy ...
Synthesis and spectroscopic 27Al NMR and Raman characterization of new materials based on the assembly of [AlO4Al12(OH)24(H2O)12] 7þ isopolycation and Co–Cr and [AlMo6O24H6] 3- Anderson heteropolyanions
(Elsevier Science, 2007-09-30)
New advanced inorganic composite materials were prepared by combination of the polycation [AlO4Al12(OH)24(H2O)12]7+ with heteropolyoxomolybdates of Anderson type structure with formula: [XMo6O24H6]3- where X=Al(III), ...
