PENTACYANOFERRATES(II) ON THE SURFACE OF ORGANOMODIFIED SILICA-GEL - THE MATRIX EFFECT
(Plenum Publ CorpNew York, 1994)
Use of silica fume and nano-silica in mortars attacked by acids present in pig manure
(2018-01-01)
Pig houses provide a highly aggressive environment to concrete structures. The chemical aggressiveness generated by pig manure may cause wear, loss in strength and premature damage to floors, leading to animal hoof diseases. ...
Submicron silica shell–magnetic core preparation and characterization
(2018-01-20)
The magnetic extraction, purification, labeling and detection of biomolecules and cells are widely applied recently. In addition, the synthesis of silica magnetic particles for biomedical applications has been developed. ...
Chemisorption on thiol-silicas: Divalent cations as a function of pH and primary amines on thiol-mercury adsorbed
(Academic Press IncSan DiegoEUA, 1997)
Adsorption of MX2 (M = Mn, Ni, Cu, Zn, and Cd; X = Cl, Br, and I) and FeCl3 by modified silica surface with imidazolylpropyl group
(1985-09-01)
Silica gel surface modified with imidazolylpropyl group was used to adsorb MX2 (M = Mn, Ni, Cu, Zn, and Cd; X = Cl, Br, and I) and FeCl3 from ethanol and acetone solution. The adsorption capacity and the intensity of the ...

β-galactosidase immobilization on controlled pore silica
(1997-12-01)
The immobilization of β-galactosidase from Kluyveromyces fragilis on controlled pore silica was investigated. Immobilization was performed on amino silica activated with glutaraldehyde and the product was applied to the ...
Avaliação da atividade pozolânica da sílica nanoestruturada sol-gel e sílica ativa via ensaio de variação de condutividade elétrica
(Universidade Federal de Minas GeraisUFMG, 2017-05-04)
Active pozzolanic admixtures are added in concrete to improve some of its properties, such as compressive strength and density. Due to its composition and structure, silica synthetized by sol-gel technique has a great ...
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 ...
