Graphene is a two dimensional material composed by carbon atoms arranged in a honeycomb lattice. During the past decade, it has attracted enormous interest due to the relativistic Dirac nature of its charge carriers and ...

There are many examples of the oil relevance in today’s society, such as, manufacturing of materials, fuels production and huge significance on the country's economy. Concerning the exploration of this product some ...

Since the 90s, the petroleum industry has been conducting research on alloys that are wear and corrosion resistant once several equipment parts used in the oil exploitation, extraction and production, such as pipes, joints, ...

In general the physical properties of materials depend intrinsically on symmetries. A property clearly dependent on symmetry is the ability of non-centrosymmetric materials to generate light with twice the incident frequency, ...

In this work, we made use of first principles calculations based on the density functional theory formalism to describe structural and electronic properties of carbon and boron nitride nanomaterials. The thesis is composed ...

In the last years, the study of bidimensional semiconductors (2D) has attracted great interest aiming scientific and technological applications, because they are promising materials for the production of ultrafine and ...
