Nanocomposites of polyamide 6 with organoclay have been prepared by melt intercalation method. The properties that were studied: processing variables (speed and configuration of screw and feeding rate); three molecular weigth ...

Mechanical properties and fracture behavior of heterophasic polypropylene (PP) and PP composites with wood particles were studied by the Essential Work of Fracture (EWF) method. All formulations, with and without coupling ...

The Glass Ionomer Cements (GICs) are widely used materials in dentistry have fluoride release, chemical adhesion to the substrate and dental thermal expansion similar to tooth structure. The limitation of their use is given ...

The present work is concerned with the effect of the chemical treatment of the fibers, loading level of sisal fiber and organoclay, compounding equipment, and thermal aging time on the mechanical and thermo-mechanical ...

Membranes are classificad as semipermeable, which under certain driving force, allows the preferential passage of one or more species or components present in a solution. Ceramic membranes can be used in environments with ...

The use of cannulas in the digestive system of ruminants is often required for experimental studies of digestibility. The cannulas used today are made from synthetic polymers presenting minimal interaction with the biological ...

The vigorous industrialization of modern world, high consumption, accelerated rhythm of the innovation and programmed obsolescence do with that electronic equipments become electronic waste in short time. Thousands of ...

The transesterification of vegetable oils for the production of alkyl esters (biodiesel) can be used with a potential substitute for exhaustible diesel oil. Several communications has focused on the development process ...

The objective of this study was to synthesize compounds Mo/TixZr1-xO2 catalytic materials, and its evaluation in Sour Gas Shift reactions and selective catalytic reduction with ammonia (SCR-NH3). The catalyst supports ...
