Congo red immobilized on a silica/aniline xerogel: Preparation and application as an amperometric sensor for ascorbic acid
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2005)
POROSITY EVOLUTION IN SNO2 XEROGELS DURING SINTERING UNDER ISOTHERMAL CONDITIONS
(American Physical Soc, 1995-04-01)
A nonisothermal study of the kinetics of the nanoporosity elimination in sonogels-derived silica xerogels
(Amer Chemical Soc, 2005-03-10)
A nonisothermal study of the kinetics of the nanoporosity elimination in monolithic silica xerogels, prepared from acid and ultrasound catalyzed hydrolysis of tetraethylortosilicate (TEOS), has been carried out by means ...
Visible and near-infrared luminescent Eu(3+) or Er(3+) doped laponite-derived xerogels and thick films: Structural and spectroscopic properties
(ELSEVIER SCIENCE SA, 2009)
Laponite-derived materials represent promising materials for optical applications. In this work, Eu(3+)- or Er(3+)-doped laponite xerogels and films were prepared from colloidal dispersion. Homogeneous, crack-free and ...
Visible and near-infrared luminescent Eu3+ or Er3+ doped laponite-derived xerogels and thick films: Structural and spectroscopic properties
(Elsevier B.V. Sa, 2009-01-15)
Laponite-derived materials represent promising materials for optical applications. In this work, Eu3+- or Er3+-doped laponite xerogels and films were prepared from colloidal dispersion. Homogeneous, crack-free and transparent ...
Anisotropy of crystallite growth during sintering of SnO2 xerogels
(1996-12-01)
The crytallite and pore-size evolution during isothermal sintering (400 ≤ T ≤ 700°C) of SnO2 xerogels was studied by X-ray line broadening and nitrogen adsorption-desorption isotherms. The experimental results show a strong ...
SAXS measurements of the porosity in Cu(II)-doped SnO2 xerogels during crystallization
(1997-08-01)
The small-angle X-ray scattering (SAXS) technique was used to study the porosity which develops in Cu(II)-doped SnO2 monolithic xerogels during crystallization. The influence of the upper temperature of heat-treatment and ...
Effect of mesoporosity of vanadium oxide prepared by sol-gel process as cathodic material evaluated by cyclability during Li(+) insertion/deinsertion
(SPRINGER, 2010)
The effect of pore structure on the behavior of lithium intercalation into an electrode containing porous V(2)O(5) film has been investigated and compared with the electrode containing a non-porous V(2)O(5) film. X-ray ...
Ecofriendly liquid phase oxidation with hydrogen peroxide of 2,6-dimethylphenol to 2,6-dimethyl-1,4-benzoquinone catalyzed by TiO2-CeO2 mixed xerogels
(Elsevier Science, 2009-03-03)
Titania–ceria mixed xerogels were prepared with 10% (w/w) CeO2 and different pH values during the sol–gel process. The gels were dried in air and calcined at different temperature. Moreover, a sample without cerium, 100% ...
