Study of metallocene supported on porous and nonporous silica for the polymerization of ethylene
(1997)
Porous and nonporous silicas are good supports for the synthesis of coordinative heterogeneous catalysts for ethylene polymerization. The catalytic activity of nonporous Aerosil depends critically on the percentage of ...
Silica dynamics in a pampean lake (Lake Chascomús, Argentina)
(Elsevier Science, 2004-01)
Silica dynamics in a pampean lake, Lake Chascomús (Chaco-Pampa plain, Argentina) is described. Pampean lakes are shallow alkaline ecosystems, with circulation pattern corresponding to polymictic lakes, due to the nearly ...
Chemisorption on thiol-silicas: Divalent cations as a function of pH and primary amines on thiol-mercury adsorbed
(Academic Press IncSan DiegoEUA, 1997)
On the Stabilization of Gold Nanoparticles over Silica-Based Magnetic Supports Modified with Organosilanes
(WILEY-BLACKWELL, 2011)
The immobilization of gold nanoparticles (Au NPs) on silica is made possible by the functionalization of the silica surfaces with organosilanes. Au NPs could only be stabilized and firmly attached to silica-support surfaces ...
Study of metallocene supported on porous and nonporous silica for the polymerization of ethylene
(BALTZER SCI PUBL BV, 1997)
Porous and nonporous silicas are good supports for the synthesis of coordinative heterogeneous catalysts for ethylene polymerization. The catalytic activity of nonporous Aerosil depends critically on the percentage of ...
Luminescence of Eu(III) beta-diketone complex supported on functionalized macroporous silica matrix
(Elsevier B.V., 2001-11-01)
This work reports on the photoluminescent properties of the complex diequatris(thenoyltrifluoroacetonate) europium(III), which was adsorbed or supported on tubes of modified surface silica matrix. The luminescence data and ...
Preparation of silica with controlled pore sizes for enzyme immobilization
(Brazilian Society of Chemical Engineering, 2000-03-01)
A simple method for the preparation of silica with controlled pore size, for use as a support for the immobilization of enzymes, is described in this article. Using sodium silicate and hydrochloric acid, a microporous ...
