Comprehensive kinetics of hydrolysis of organotriethoxysilanes by 29Si NMR
(American Chemical Society, 2019)
Artículo / Artikulua,
The kinetics of several representative hybrid precursors were studied via 29Si NMR: three alkyl precursors, methyltriethoxysilane, ethyltriethoxysilane, and propyltriethoxysilane; as well as two unsaturated radicals, ...
Kinetics of the acid-catalyzed hydrolysis of tetraethoxysilane (TEOS) by 29Si NMR spectroscopy and mathematical modeling
(Springer, 2018)
Artículo / Artikulua,
Tetraethoxysilane (TEOS) is widely used to synthesize siliceous material by the sol–gel process. However, there is still some
disagreement about the nature of the limiting step in the hydrolysis and condensation reactions. ...
Estrategias del alumnado de Educación Secundaria para estimar la densidad
(Universitat Autònoma de BarcelonaUniversitat de València, 2018)
Artículo / Artikulua,
La densidad, o concentración de materia, es un concepto muy relevante pero que genera muchas dificultades de comprensión. Para medir la competencia en la estimación de la densidad del alumnado de la ESO, se pasó un ...
Mid-infrared spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
(Springer, 2017)
Artículo / Artikulua,
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were ...
Phenyl siloxane hybrid xerogels: structure and porous texture
(Springer US, 2019)
Artículo / Artikulua,
The aim of this research is to investigate the effect of phenyltriethoxysilane (PhTEOS) and
tetraethoxysilane (TEOS) molar ratios as silicon precursors on the structure and porous texture of xerogels.
We have prepared ...
