Electronic structure study of TiO2 polymorphs, evaluation of formic acid adsorption on dry (001) and (100) TiO2(B) facets by DFT calculations
Luciana Fernández-Werner, Ricardo Faccio, Helena Pardo +1
Structural and electronic properties comparison between anatase, rutile and monoclinic TiO2(B) titania polymorphs in bulk and related nanostructures simulated by two-dimensional sl…
Electronic and structural distortions in graphene induced by carbon vacancies and boron doping
Ricardo Faccio, Luciana Fernández-Werner, Helena Pardo +3
We present an ab initio study on the structural and electronic distortions of modified graphene by creation of vacancies, inclusion of boron atoms, and the coexistence of both, by…
Temperature oscillations of magnetization observed in nanofluid ferromagnetic graphite
S. Sergeenkov, N. S. Souza, C. Speglich +5
We report on unusual magnetic properties observed in the nanofluid room-temperature ferromagnetic graphite (with an average particle size of l=10nm). More precisely, the measured m…
Manifestation of finite temperature size effects in nanogranular magnetic graphite
S. Sergeenkov, N. S. Souza, C. Speglich +5
In addition to the double phase transition (with the Curie temperatures T_C=300K and T_{Ct}=144K), a low-temperature anomaly in the dependence of the magnetization is observed in t…
Synthesis, characterization and magnetic properties of room-temperature nanofluid ferromagnetic graphite
N. S. Souza, S. Sergeenkov, C. Speglich +7
We report the chemical synthesis route, structural characterization, and physical properties of nanofluid magnetic graphite (NFMG) obtained from the previously synthesized bulk org…
Mechanical properties of Graphene Nanoribbons
Ricardo Faccio, Pablo A. Denis, Helena Pardo +2
Herein, we investigate the structural, electronic and mechanical properties of zigzag graphene nanoribbons upon the presence of stress applying Density Functional Theory within the…
