Opinion evolution in the presence of constant propaganda: Homogeneous and localized cases
(Springer, 2021-01)
The opinion evolution of a group of agents arranged in a square lattice in the presence of external constant propaganda is studied. The contagion between agents is modeled according to the voter model, but the effect of ...
Light pseudoscalar meson masses under strong magnetic fields within the SU(3) Nambu-Jona-Lasinio model
(American Physical Society, 2021-11)
We calculate the pole masses of pseudoscalar mesons in a strongly magnetized medium within the framework of the SU(3) Nambu-Jona-Lasinio model, using a magnetic field-independent regularization scheme. We employ both a ...
Synthesis and characterization of Cu2+ substituted magnetite
(SPRINGER, 2011-11-01)
Samples of magnetite, both pure and doped with divalent copper, Fe3-xCuxO4, with x = 0, 0.05, 0.10 and 0.20 atm.%, were synthesized hydrothermally. The samples were characterized by Atomic Absorption Spectroscopy, Mössbauer ...
Towards a full understanding of the growth dynamics and optical response of self-assembled photonic colloidal crystal films
(Royal Society of Chemistry, 2009-12)
Recent advances in the comprehension of the growth dynamics of colloidal crystal films opens the door to rational design of experiments aiming at fabricating lattices in which the density of intrinsic defects is minimized. ...
About the species formed during the electrochemical half oxidation of polyaniline: Polaron-bipolaron equilibrium
(Pergamon-Elsevier Science Ltd, 2018-04)
The UV–Vis spectra of polyaniline (Pani) films were measured in the range 200 nm–900 nm, at constant potential as well as sweeping the potential. Both free standing films and Pani films deposited on ITO substrates were ...
Sintering kinetics of nanocrystalline Ce0.9Zr0.1O2 prepared by gel combustion method
(Springer, 2020-01-23)
The sintering process of nanometric Ce0.9Zr0.1O2 mixed oxides prepared by the amino acid–nitrate gel combustion method was analyzed by dilatometry using the constant heating rate (CHR) and stepwise isothermal dilatometry ...
ESTUDIO ESTRUCTURAL POR RAYOS X Y DE TEMPERATURA DE TRANSICIÓN A SUPERCONDUCTIVIDAD DE LA ALEACIÓN Pb-Bi

Inter-domain interactions in charged lipid monolayers
(American Chemical Society, 2014-01)
Phase coexistence is common in model biomembranes with the presence of domains formed by lipids in a dense phase state modulating lateral diffusion of species through hydrodynamic and electrostatic interactions. In this ...
Structural order in ultrathin films of the monolayer protected clusters based upon 4 nm gold nanocrystals: an experimental and theoretical studyStructural order in ultrathin films of the monolayer protected clusters based upon 4 nm gold nanocrystals: an experimental and theoretical study
(Royal Society of Chemistry, 2014-05)
The structural order in ultrathin films of monolayer protected clusters (MPCs) is important in a number of application areas but can be difficult to demonstrate by conventional methods, particularly when the metallic core ...
Magnetic catalysis and inverse magnetic catalysis in nonlocal chiral quark models
(American Physical Society, 2017-02)
We study the behavior of strongly interacting matter under an external constant magnetic field in the context of nonlocal chiral quark models within the mean field approximation. We find that at zero temperature the behavior ...
