Alloys and oxides on carbon-supported Pt-Sn electrocatalysts for ethanol oxidation
(Journal of Power Sources, 2010-06-01) [Resumo]
This work reports studies of ethanol oxidation on Pt-Sn/C catalysts with nearly the same particle size and identical overall composition having different amounts of oxide and alloyed phases. Results of characterization of ...
Removal of metal ions from aqueous solution by chelating polymeric hydrogel
(Environmental Chemistry Letters, 2010-12-01) [Resumo]
Polysaccharide natural seed coat from the tree Magonia pubescens, in the form of hydrogel was used to remove metals in aqueous solution. Swelling tests indicate that seed coat presents hydrogel behavior, with maximum water ...
X-ray diffraction data of tibolone Delta(4) isomer (isotibolone)
(Powder Diffraction, 2009-12-01) [Resumo]
Tibolone is used for hormone reposition of postmenopause women and isotibolone is considered the major degradation product of tibolone. Isotibolone can also be present in tibolone API raw materials due to some inadequate ...
Structural and morphological characteristics of (Pb1-x Sr (x) )TiO3 powders obtained by polymeric precursor method
(Journal of Sol-Gel Science and Technology, 2010-01-01) [Resumo]
Pb1-x Sr (x) )TiO3 powders with different compositions (x = 0, 0.10, 0.50, 0.90 and 1) were synthesized by the polymeric precursor method and heat treated at 800 A degrees C for 2 h under air atmosphere. The thermogravimetric ...
In2O3 microcrystals obtained from rapid calcination in domestic microwave oven
(Materials Research Bulletin, 2010-11-01) [Resumo]
The simple way to prepare In2O3 microcrystals is reported in this paper. The precursor, In(OH)(3) microstructures, were obtained using the Microwave-Assisted Hydrothermal (MAH) Method. By annealing as-prepared In(OH)(3) ...
Electrogravimetric Real-Time and in Situ Michaelis-Menten Enzimatic Kinetics: Progress Curve of Acetylcholinesterase Hydrolysis
(Journal of Physical Chemistry B, 2010-12-16) [Resumo]
A piezoelectric detection of enzyme-modified surface was performed under Michaelis-Menten presumptions of steady-state condition. The approach herein presented showed promise in the study of enzymatic kinetics by measuring ...
