Aerogeles con aplicaciones en biomedicina y medioambiente
(Sociedad Espanola de Ceramica y Vidrio, 2007)
Es posible preparar materiales híbridos inorgánico-orgánicos incorporando una fase orgánica sobre un sol obtenido por hidrólisis de metalorgánico mientras se aplican ultrasonidos de alta potencia. Cuando las dos fases ...

Larnite powders and larnite/silica aerogel composites as effective agents for CO2 sequestration by carbonation
(Elsevier, 2009)
This paper presents the results of the carbonation reaction of two sample types: larnite (Ca2SiO4) powders and larnite/silica aerogel composites, the larnite acting as an active phase in a process of direct mineral ...

The cluster model: A hierarchically-ordered assemblage of random-packing spheres for modelling microstructure of porous materials
(Elsevier, 2008)
A new structural model based on the premises widely used for describing the structure of random materials, and especially aerogels, is introduced. Aerogels are described as an assemblage of randomly-packed spheres in several ...

Bioactivity of wollastonite/aerogels composites obtained from a TEOS-MTES matrix
(Springer Nature, 2008)
Organic-inorganic hybrid materials were synthesized by controlled hydrolysis of tetraethoxysilane (TEOS), methyltrimethoxysilane (MTES), synthetic wollastonite powders and polydimethylsiloxane (PDMS) in an ethanol solution. ...

Nanostructured sonogels
(Trans Tech Publications Ltd, 2009)
Acoustic cavitation effects in sol-gel liquid processing permits to obtain nanostructured materials, with size-dependent properties. The so-called "hot spots" produce very high temperatures and pressures which act as ...

Propiedades mecánicas de aerogeles híbridos de sílice
(Sociedad Espanola de Ceramica y Vidrio, 2005)
Se han obtenido aerogeles híbridos de sílice orgánico-inorgánico por aplicación de ultrasonidos de alta potencia en los precursores líquidos y posterior secado del gel húmedo en condiciones supercríticas en etanol. Las ...

The cluster model: A simulation of the aerogel structure as a hierarchically-ordered arrangement of randomly packed spheres
(Springer Nature, 2005)
A new structural model based on the premises widely used for describing the structure of aerogels has been introduced. These structures have been described as an assemblage of randomly-packed spheres in several ...

SANS study of hybrid silica aerogels under "in situ" uniaxial compression
(Springer Nature, 2008)
We have modified the inorganic silica network of aerogels with polydimethylsiloxane (PDMS), a hydroxyl-terminated polymer, to obtain an organic modified silicate (ORMOSIL). Reactions were assisted by high-power ultrasounds. ...
