The study of ceramic composites assisted by computer simulation is well spread nowadays. It is an interest of the ceramic industry the development of materials models trustfully enough to reduce cost with prototypes and ...

Samples of a polypropylene (PP) homopolymer were nucleated with three different nucleating agents: 1,3:2,4-bis (3,4-dimethylobenzylideno) sorbitol (DMDBS), bis(4-propylbenzylidene) propilsorbitol (propilsorbitol), and ...

In this study nanocomposites of polyamide-6 (PA-6) reinforced with silica nanoparticles (SiO2) were prepared in order to promote improved mechanical properties for engineering applications. The nanoparticles’ surfaces ...

The morphology of extruded multiphase polymer systems is usually assessed through off-line characterization methods such as microscopy, which require much time for sample preparation and analysis of the results. This ...

The constant search for means to reduce the energetic consumption motivates the use of high emissivity ceramic coatings in many high temperature applications. Its use aims to increase heat transfer efficiency by radiation ...

The discovery of new promising oil extraction sites in Brazil coast led to a great search for novel functionalized materials to withstand the demanding conditions from offshore oil exploitation. Stainless steels, such ...

Itaipu Binational along with the Swiss company power generation Kraftwerke Oberhasli AG/KWO, are developing a battery of nickel-sodium salt (Na/NiCl2), which uses β/β"-Al2O3 ceramic as solid electrolyte, to apply on electric ...

Solution blow spinning is a technique to produce micro- and nano-scale fibers, forming films with high porosity and surface area. Chemical modifications or the incorporation of nanostructures in these fibers can improve ...

In this research project, epoxy/carbon nanotubes/mineral fillers hybrid nanocomposites were produced using a high energy sonication process. Moreover, two epoxy resins based on DGEBA with different viscosities were used, ...

During steel ingot solidification, internal voids are expected to be formed in its interior. Such voids, if they stay in the final product after the forging step, will hurt the performance and properties of the final ...
