Andreia Fonseca de Faria,Diego Stéfani T. Martinez,Stela Maris Meister Meira,Ana C.M. de Moraes,Adriano Brandelli,Antonio G. Souza Filho,Oswaldo Luiz Alves +6 more
TL;DR: This work provides the first direct evidence that GO-Ag nanocomposites can inhibit the growth of microbial adhered cells, thus preventing the process of biofilm formation, and support the idea thatGO-Ag Nanocomposite may be applied as antibacterial coatings material to prevent the development of biofilms in food packaging and medical devices.
Journal ArticleDOI
Optimized graphene transfer: Influence of polymethylmethacrylate (PMMA) layer concentration and baking time on graphene final performance
Gabriela Borin Barin,Gabriela Borin Barin,Yi Song,Iara F. Gimenez,Antonio G. Souza Filho,Ledjane Silva Barreto,Jing Kong +6 more
TL;DR: In this article, the influence of transfer parameters on the final structure, morphology and electrical properties of graphene were investigated, and it was shown that a double layer of PMMA can enhance or degrade graphene quality depending on its concentration.
Journal ArticleDOI
Review on the symmetry-related properties of carbon nanotubes
Eduardo B. Barros,Eduardo B. Barros,Ado Jorio,Georgii G. Samsonidze,Rodrigo B. Capaz,Antonio G. Souza Filho,Josué Mendes Filho,Gene Dresselhaus,Mildred S. Dresselhaus +8 more
TL;DR: In this paper, the basic properties of carbon nanotubes from the standpoint of group theory are reviewed, and the zone folding scheme is reviewed in the light of the helical symmetry of the nanotube.
Journal ArticleDOI
Thermal decomposition and structural reconstruction effect on Mg–Fe-based hydrotalcite compounds
Odair Pastor Ferreira,Oswaldo Luiz Alves,D. X. Gouveia,D. X. Gouveia,Antonio G. Souza Filho,José A. C. de Paiva,Josué Mendes Filho +6 more
TL;DR: In this article, the thermal decomposition and structural reconstruction of Mg-Fe-based hydrotalcites have been studied through thermogravimetric analyses, X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy and Mossbauer Spectroscopy.
Journal ArticleDOI
Raman evidence for pressure-induced formation of diamondene
Luiz Gustavo Pimenta Martins,Luiz Gustavo Pimenta Martins,Matheus J. S. Matos,Alexandre Rocha Paschoal,Paulo Freire,N. F. Andrade,A. L. Aguiar,Jing Kong,Bernardo R. A. Neves,Alan B. de Oliveira,Mario S. C. Mazzoni,Antonio G. Souza Filho,Luiz Gustavo Cançado +12 more
TL;DR: Spectroscopic evidence for the formation of diamondene is provided by performing Raman spectroscopy of double-layer graphene under high pressure and is explained in terms of a breakdown in the Kohn anomaly associated with the finite size of the remaining graphene sites surrounded by the diamondene matrix.
