Quimisorción reactiva de H S sobre una sílice mesoporosa impregnada con vanadio
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2015)
Silicates characterization as potential bacteriocin-carriers
(Elsevier, 2010-01)
Two different silicates, zeosil and expanded perlite, were characterized as potential carriers of a bacteriocin with anti-Listeria monocytogenes activity, produced by Enterococcus faecium CRL1385. Specific surface areas ...
Response of sugarcane ratoon to nitrogen without and with the application of silicon
(Taylor & Francis Inc, 2016-01-01)
The objective was to evaluate the effect of nitrogen, associated to silicon, on soil chemical properties, nutritional status and yield of the second sugarcane ratoon. The experiment was carried out at a Haplustox, loamy ...
Assessment of the efficacy of ethyl silicate and dibasic ammonium phosphate consolidants in improving the durability of two building sandstones from Andalusia (Spain)
(Springer Verlag, 2018)
We performed a comparative study of the efectiveness of ethyl silicate (TEOS) and dibasic ammonium phosphate (DAP)
on two varieties of natural stone used in the architectural heritage of Andalusia (Spain): Arenisca Ronda ...
Natural silicate-TiO2 hybrids for photocatalytic oxidation of formaldehyde in gas phase
(Elsevier B.V., 2017)
© 2016 Elsevier B.V. Structured hybrid materials based on the combination adsorbent-photocatalyst with optimal mechanical resistance and reduced cost, are prepared by extrusion using four different natural silicates with ...
Red and blue emissions of europium doped gadolinium silicate from porous silica matrix and hydroxide carbonate with spherical shaped particles
(Elsevier B.V., 2002-10-07)
In this work, Eu(III) and Eu(II) doped gadolinium silicates has been obtained as compact tubes starting from spherical gadolinium hydroxide carbonate using the pores of silica matrix as support and its surface as reagent. ...
Effect of calcium and magnesium silicate on the growth of the castor oil plant subjected to salinity levels
(Universidade Estadual de Londrina (UEL), 2012-01-01)
Salt stress decreases the osmotic potential of soil solution causing water stress, causing toxic effects in the plants resulting in injuries on the metabolism and nutritional disorders, thus compromising the plant growth, ...
Effects of temperature and of the addition of accelerating and retarding agents on the kinetics of hydration of tricalcium silicate
(2000-12-28)
The formation of calcium silicate hydrates (C-S-H) during the hydration of tricalcium silicate (C3S) in pure water and in water solutions containing 1% CaCl2 (accelerator) and 0.01% saccharose (retarder) was studied by ...
