The convergence to the fixed point near at a transcritical bifurcation and the organization of the extreming curves for a parametric perturbed Hassell mapping are investigated. The evolution of the orbits towards the fixed ... -
Resonant electron tunneling spectroscopy of antibonding states in a Dirac semimetal
Marques, Y.; ; ; Seridonio, A. C. (Physical Review B, 2018) [Artigo]
Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphene. Moreover, it was suggested that under ... -
Effect of different synthesis methods on the textural properties of calcium tungstate (CaWO4) and its catalytic properties in the toluene oxidation
