A TDDFT-based Study on the Proton-DNA Collision
R. Seraide, M. A. Bernal, G. Brunetto +2
The interaction of heavy charged particles with DNA is of interest for several areas, from hadrontherapy to aero-space industry. In this paper, a TD-DFT study on the interaction of…
Synthesis, characterization and computational simulation of graphene nanoplatelets stabilized in poly(styrene sulfonate) sodium salt
Celina M. Miyazaki, Marco A. E. Maria, Daiane Damasceno Borges +8
The production of large area interfaces and the use of scalable methods to build-up designed nanostructures generating advanced functional properties are of high interest for many…
Nanodroplets Impacting on Graphene
Ygor M. Jaques, Gustavo Brunetto, Douglas S. Galvao
The unique and remarkable properties of graphene can be exploited as the basis to a wide range of applications. However, in spite of years of investigations there are some importan…
Torsional 'Superplasticity' of Graphyne Nanotubes
Jose M. de Sousa, Gustavo Brunetto, Vitor R. Coluci +1
Graphyne is a planar two-dimensional carbon allotrope formed by atoms in sp, sp2, and sp3 hybridized states. Topologically graphyne nanotubes (GNTs) can be considered as cylindrica…
High Pressure Induced Binding Between Linear Carbon Chains and Nanotubes
Gustavo Brunetto, Nádia F. Andrade, Douglas S. Galvão +1
Recent studies of single-walled carbon nanotubes (CNTs) in aqueous media have showed that water can significantly affect the tube mechanical properties. CNTs under hydrostatic comp…
Graphene-like Membranes: From Impermeable to Selective Sieves
G. Brunetto, D. S. Galvao
Recently, it was proposed that graphene membranes could act as impermeable atomic structures to standard gases. For some other applications, a higher level of porosity is needed, a…
Simulating pump-probe photo-electron and absorption spectroscopy on the attosecond time-scale with time-dependent density-functional theory
Umberto De Giovannini, Gustavo Brunetto, Alberto Castro +2
Molecular absorption and photo-electron spectra can be efficiently predicted with real-time time-dependent density-functional theory (TDDFT). We show here how these techniques can…
A Nonzero Gap Two-Dimensional Carbon Allotrope from Porous Graphene
G. Brunetto, P. A. S. Autreto, L. D. Machado +3
Graphene is considered one of the most promising materials for future electronic. However, in its pristine form graphene is a gapless material, which imposes limitations to its use…
Designing Conducting Polymers Using Bioinspired Ant Algorithms
Bruno V. C. Martins, Gustavo Brunetto, Fernando Sato +2
Ant algorithms are inspired in real ants and the main idea is to create virtual ants that travel into the space of possible solution depositing virtual pheromone proportional to ho…
