Journal ArticleDOI
Comparative study of first- and second-order Raman spectra of MWCNT at visible and infrared laser excitation
E.F. Antunes,Anderson Oliveira Lobo,Evaldo José Corat,Vladimir Jesus Trava-Airoldi,Airton Abrahão Martin,C. Veríssimo +5 more
TL;DR: In this paper, first-and second-order Raman spectra of multwalled carbon nanotubes (MWCNTs) and three other graphitic materials (powdered graphite, carbon fiber, and pyrolytic graphite) were compared.
Journal ArticleDOI
Influence of diameter in the Raman spectra of aligned multi-walled carbon nanotubes
TL;DR: In this paper, the relative intensity of the G′ band and the G and G′ bandwidths have high sensitivity to tube diameter distribution and also to structural variations along the tube axis, while the D band is sensitive to structural organization, particularly along tube axis.
Journal ArticleDOI
Evaluation of residual iron in carbon nanotubes purified by acid treatments
Elilton Rodrigues Edwards,E.F. Antunes,Edson Cocchieri Botelho,Maurício Ribeiro Baldan,Evaldo José Corat +4 more
TL;DR: A detailed analysis by X-ray photoelectron spectroscopy was carried out on multi-walled carbon nanotube (MWCNT) surfaces after non-oxidative and oxidative purification treatments in liquid-phase.
Journal ArticleDOI
Porous boron-doped diamond/carbon nanotube electrodes.
Hudson Zanin,Paul W May,David J. Fermín,Daniela Plana,Sara M. C. Vieira,William I. Milne,Evaldo José Corat +6 more
TL;DR: These nanostructured CNT/BDD composite electrodes have the excellent, well-known characteristics associated with BDD, but also they have electroactive areas and double-layer capacitance values ∼450 times greater than those for the equivalent flat BDD electrodes.
Journal ArticleDOI
Adhesion studies of diamond-like carbon films deposited on Ti6Al4V substrate with a silicon interlayer
TL;DR: In this paper, the authors observed the behavior of different thicknesses of silicon interlayer between diamond-like carbon (DLC) films and Ti6Al4V substrates and analyzed the relation of growth parameters to the mechanical properties of DLC films.
