Universal asymptotic behavior in nonlinear systems driven by a two-frequency forcing
(American Physical Society, 2013)
We examine the time-dependent behavior of a nonlinear system driven by a two-frequency forcing. By using a nonperturbative approach, we are able to derive an asymptotic expression, valid in the long-time limit, for the ...

Thermal equilibrium in Einstein’s elevator
(American Physical Society, 2013)
We report fully relativistic molecular-dynamics simulations that verify the appearance of thermal equilibrium of a classical gas inside a uniformly accelerated container. The numerical experiments confirm that the local ...

PT-symmetry management in oligomer systems
(2013)
We study the effects of management of the PT-symmetric part of the potential within the setting of Schrödinger dimer and trimer oligomer systems. This is done by rapidly modulating in time the gain/loss profile. This gives ...

Kinks supersónicos en redes repulsivas
(Real Sociedad Española de Física, 2013-07-07)
We have founds supersonics kinks in a model for the cation layer of mica muscovite. They are proposed as a posible explanation for the dark tracks in the mineral

Tidal circulation, sediment and pollutant transport in Cádiz Bay (SW Spain): A modelling study
(Elsevier, 2013)
A numerical model to simulate the dispersion of particle-reactive tracers in Cádiz Bay (SW Spain) has been developed. It includes a hydrodynamic submodel to provide water currents, a sediment transport submodel, which ...

Ag+ release and corrosion behavior of zirconium carbonitride coatings with silver nanoparticles for biomedical devices
(ScienceDirect, 2013-05-15)
Zirconium carbonitride coatings with silver nanoparticles were produced by DC unbalanced dual magnetron sputtering system, using two targets, Zr and Zr/Ag in an Ar, C2H2 and N2 atmosphere. Stainless steel 316L and silicon ...

Ag+ release inhibition from ZrCN–Ag coatings by surface agglomeration mechanism: structural characterization
(IOP Science, 2013)
New multifunctional materials based on well-established materials to which functional properties are added, such as antibacterial performance, have become a relevant research topic, in order to meet the requirements of ...

High- and low-energy x-ray photoelectron techniques for compositional depth profiles: destructive versus non-destructive methods
(IOP Science, 2013-01-17)
Hard x-ray photoelectron spectroscopy (HAXPES), angle-resolved x-ray photoelectron spectroscopy (ARXPS) and x-ray photoelectron spectroscopy (XPS) with simultaneous Ar+ bombardment are used to obtain chemical information ...

First spectral emissivity study of a solar selective coating in the 150–600 1C temperature range
(ScienceDirect, 2013-10)
A complete experimental study of temperature dependence of the total spectral emissivity has been performed, for the first time, for absorber–reflector selective coatings used in concentrated solar power (CSP) systems for ...

Advanced surface characterization of silver nanocluster segregation in Ag–TiCN bioactive coatings by RBS, GDOES, and ARXPS
(SpringerLink, 2013)
Surface modification by means of wear protective and antibacterial coatings represents, nowadays, a crucial challenge in the biomaterials field in order to enhance the lifetime of bio-devices. It is possible to tailor the ...
