Tunability of hybrid silica xerogels: surface chemistry and porous texture based on the aromatic precursor
(MDPI, 2023)
Artículo / Artikulua,
The interest in new materials with specific properties has increased because they are essential for the environmental and technological needs of our society. Among them, silica hybrid
xerogels have emerged as promising ...
The narrative of a line of research from a feminist perspective: fiber optic sensors and actor-network theory (ANT)
(MDPI, 2022)
Artículo / Artikulua,
The narrative of a line of research from a feminist perspective involves describing the
situated practices that contribute to understanding inequality in the construction of the social relationships that build links between ...
Novel silica hybrid xerogels prepared by co-condensation of TEOS and ClPhTEOS: a chemical and morphological study
(MDPI, 2022)
info:eu-repo/semantics/article,
The search for new materials with improved properties for advanced applications is, nowadays, one of the most relevant and booming fields for scientists due to the environmental and technological needs of our society. ...
Steering the synthesis of Fe3O4 nanoparticles under sonication by using a fractional factorial design
(Elsevier, 2021)
info:eu-repo/semantics/article,
Superparamagnetic iron oxide nanoparticles (MNPs) have the potential to act as heat sources in magnetic hyperthermia. The key parameter for this application is the specific absorption rate (SAR), which must be as large as ...
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. ...
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, ...
From fundamental materials chemistry to sensing applications: unravelling the water adsorption mechanism of a luminescent optical fibre sensor membrane
(Elsevier, 2024)
Artículo / Artikulua,
This work provides insight into the correlation between the luminescent response of a water-vapour optical fibre sensor and the textural properties of its lanthanide-doped silica coating. To this end, a library of 16 silica ...
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 ...
Hybrid xerogels: study of the sol-gel process and local structure by vibrational spectroscopy
(MDPI, 2021)
info:eu-repo/semantics/article,
The properties of hybrid silica xerogels obtained by the sol-gel method are highly dependent on the precursor and the synthesis conditions. This study examines the influence of organic substituents of the precursor on the ...
Fiber optic sensors based on hybrid phenyl-silica xerogel films to detect n-hexane: determination of the isosteric enthalpy of adsorption
(Beilstein-Institut, 2017)
info:eu-repo/semantics/article,
We investigated the response of three fiber optic sensing elements prepared at pH 10 from phenyltriethoxysilane (PhTEOS) and
tetraethylsilane (TEOS) mixtures with 30, 40, and 50% PhTEOS in the silicon precursor mixture. ...
