The epoxy resin modified with carboxyl-terminated polybutadiene presented improved impact resistance and outstanding mechanical performance in terms of flexural and tensile

Different carbon nanostructured materials, such as nanotubes, nanofibers, nanosprings and nanooctopus, were grown by changing the metal catalyst and experimental parameters of

isotherms to experimental data shows that copper adsorption increases 3.5-fold for MAC, the oxidized sample, as compared with data for RAC. Experiments conducted in this work show

materials were compared with a commercial activated carbon, they presented higher values in several properties (specific surface area and volume of pores), characteristics that

In this paper we investigate the characteristics of SiC obtained by high temperature annealing of amorphous hydrogenated silicon carbide a-Si 1-x C x :H films deposited by PECVD

In order to understand the effect of nitrogen incorporation on the structure of the films, the parameters were determined from the Raman spectra analysis of the films and found to

On one hand, when agglomerated silica spheres where used as patrix, porous carbon matrixes with very high specific surface area and a relatively narrow pore size distribution

FTIR and NMR spectra were qualitatively similar for all samples (Figure 1) and aromaticity indexes and elemental analysis data obtained are shown in Table 1..
