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 ...

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 ...

Reinforced silica-carbon nanotube monolithic aerogels synthesised by rapid controlled gelation
(Springer Nature, 2018)
This work introduces a new synthesis procedure for obtaining homogeneous silica hybrid aerogels with carbon nanotube contents up to 2.50 wt.%. The inclusion of nanotubes in the highly porous silica matrix was performed by ...

Mechanical characterization of sol-gel alumina-based ceramics with intragranular reinforcement of multiwalled carbon nanotubes
(Elsevier, 2020)
Multiwalled carbon nanotubes (MWCNTs) have been widely considered for mechanical reinforcement of ceramic matrix composites. Nevertheless, the efficiency of this reinforcement strategy is under debate due to fabrication ...

Hybrid aerogels and bioactive aerogels under uniaxial compression: an in situ saxs study
(2010)
The complex structure of hybrid organic/inorganic aerogels is composed by an inorganic phase covalently bonded to an organic chain forming a copolymer. Conventional hybrid aerogels were studied as well as bioactive hybrid ...

Absorption capacity, kinetics and mechanical behaviour in dry and wet states of hydrophobic DEDMS/TEOS-based silica aerogels
(Springer Nature, 2017)
This work is a new approach to the study of the structural, mechanical and absorption properties of hybrid organic/inorganic silica-based aerogels. Diethoxydimethylsilane and tetraethoxysilane have been used as precursors. ...
