Demulsification of water/sunflower oil emulsions by a tangential filtration process using chemically impregnated ceramic tubes
(Elsevier B.V., 2007-02-15)
A tangential filtration process was implemented in this study using porous ceramic tubes made of alpha-alumina produced by the slip-casting technique. These tubes were sintered at 1450 degrees C and characterized by mercury ...
ETHYL SILICATES WITH DIFFERENT HYDROLYSIS DEGREE LIKE NON-FLAMMABLE IMPREGNATING MATERIAL FOR WOOD
(Universidad del Bío-Bío, 2008)
Effect of bituminous impregnation on nonwoven geotextiles tensile and permeability properties
(ELSEVIER SCI LTD, 2011)
Geosynthetics interlayer systems are effective techniques to control reflective cracking in damaged pavements. It comprises the inclusion of nonwoven geotextiles between the damaged layer and the new overlay of the pavement ...
Dynamical aspects of hardwood impregnation
(De Gruyter, 2000-02)
The phenomenon of axial liquid penetration in hardwoods is modeled through two different mechanisms: in one of them the driving force is taken to be the empty space that remains unfilled inside the material; in the other ...
Effect of temperature on glass-ceramic films prepared by impregnation of commercial float glass surfaces with oxide powders under pressure
(Elsevier B.V. Sa, 2010-08-31)
SnO(2) samples were prepared as ultrafine powder by a chemical synthesis method and deposited on the surface of commercial float glass substrates The glass surface was impregnated with these powders under high gas pressure ...
Eugenol-loaded LLDPE films with antioxidant activity by supercritical carbon dioxide impregnation
(Elsevier Science, 2016-05)
In this work, linear low density polyethylene (LLDPE) films were impregnated with eugenol using supercritical CO2 impregnation, as a strategy for obtaining a loaded material to be potentially applied in active food packaging. ...
Vaccine effectiveness and use of collar impregnated with insecticide for reducing incidence of Leishmania infection in dogs in an endemic region for visceral leishmaniasis, in Brazil
(Cambridge Univ Press, 2018-02-01)
Although a national programme for control of visceral leishmaniosis (VL) is being run in Brazil, the disease continues to spread. This programme is essentially based on culling infected dogs from endemic regions. Thus, ...
Comparative study of the physicochemical properties and photocatalytic activity of modified mcm-41 synthesized by direct (one-step) incorporation and impregnation
(Sociedade Brasileira de Química, 2016-03)
MCM-41 structures were synthesized and modified by direct (one-step) incorporation (DI) and wet impregnation (WI) methods. The solids were characterized by XRF, XRD, N2 adsorption and UV-Vis DR, and catalytically evaluated ...
Magnetic properties of Co-impregnated zeolites
(Elsevier Science, 2009-11-03)
The structure and magnetic properties of Co-containing zeolites prepared by wet impregnation were investigated. The samples were calcined and then reduced in flowing H2. The samples studied have large saturation magnetization ...
