A new parametrization scheme of DFT-D is proposed with the aim of devising a methodology for the study of graphitic material. The main feature of the new system is the geometry optimization within the fitting scheme. The DFT-D parameters are obtained for the benzene dimer, a good model molecule for graphitic systems. Very accurate CCSD(T) results are used(More)
A simple and expedite electrochemical methodology was developed for the determination of ciprofloxacin, based on a glassy carbon (GC) electrode modified by a combination of multi-walled carbon nanotubes (MWCNT) with β-cyclodextrin (β-CD) incorporated in a polyaniline film. The combined use of β-CD and MWCNT in the electrochemical sensor leads to a(More)
The benzene dimer is arguably the simplest molecular analogue of graphitic materials. We present the systematic study of minima and transition states of the benzene dimer with semiempirical and molecular mechanics (MM) methods. Full minimizations on all conformations were performed and the results, geometries, and binding energies were compared with CCSD(T)(More)
The properties of graphene nanoribbons are highly dependent on structural variables such as width, length, edge structure, and heteroatom doping. Therefore, atomic precision over all these variables is necessary for establishing their fundamental properties and exploring their potential applications. An iterative approach is presented that assembles a small(More)
Twisted two-dimensional aromatic frameworks have been prepared by overcrowding the nodes with bulky and rigid substituents. The highly distorted aromatic framework with alternating out-of-plane substituents results in diminished interlayer interactions that favor the exfoliation and dispersion of individual layers in organic media.
