چکیده
Abstract Nanomaterials and nanocomposites have gained relevance in science technology due to their excellent properties. Therefore, the characterization of these materials is important. Thermogravimetric analysis a powerful technique for iron-carbon nanotubes (Fe/MWCNT) as hybrid nanomaterials, which may be prepared by impregnation step (alkaline or microwave-assisted precipitation). High-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD situ XRD), photoelectron spectroscopy (XPS), thermogravimetric (TGA) were instrumental techniques used characterize materials. Through TGA, it was possible determine quantity effective impregnated iron on MWCNT. Further, nitrogen atmosphere reveals thermal event reflecting reduction C from MWCNT shape signal reflects dispersion size particles surface. This related particle sizes chemical nature oxides present. Thermal events TGA correlated with results obtained XRD, XPS, HR-TEM. The presence smaller well-distributed nanoparticles impacts reducing TGA. temperature observed curves metal compounds present, such nitrates oxides. These suggest that can rapid economical evaluation different Fe/MWCNT material facilitate estimation structural nanohybrid permit projections potential applications.

Designing Neat and Composite Carbon Nanotube Materials by Porosimetric Characterization
We propose a porosimetry-based method to characterize pores formed by carbon nanotubes (CNTs) in the CNT agglomerates for designing neat CNT-based materials and composites. CNT agglomerates contain pores between individual CNTs and/or CNT bundles (micropore < 2 nm, mesopores 2-50 nm, and macropores > 50 nm). We investigated these pores structured by CNTs with different diameters and number of w...
