Optical properties and refractive index sensitivity of reactive sputtered oxide coatings with embedded Au clusters
(AIP Publishing, 2014-02-14)
In the present study, nanocomposite coatings of Au clusters embedded in two different oxides, TiO2 and Al2O3, were synthesized using pulsed DC magnetron sputtering. The depositions were carried out in three steps, by ...

Influence of the surface morphology and microstructure on the biological properties of Ti–Si–C–N–O coatings
(ScienceDirect, 2010-08-02)
Detailed structural, microstructural, biofilm formation and cytotoxicity studies were performed on Ti–Si–C–ON hard coatings prepared by DC reactive magnetron sputtering, in order to evaluate the relation among these ...

Nonlinear Dirac equation solitary waves in external fields
(2012)
We consider nonlinear Dirac equations (NLDE's) in the 1+1 dimension with scalar-scalar self-interaction g2κ+1(Ψ¯¯¯Ψ)κ+1 in the presence of various external electromagnetic fields. We find exact solutions for special external ...

From nodeless clouds and vortices to gray ring solitons and symmetry-broken states in two-dimensional polariton condensates
(2014)
We consider the existence, stability and dynamics of the nodeless state and fundamental nonlinear excitations, such as vortices, for a quasi-two-dimensional polariton condensate in the presence of pumping and nonlinear ...

Control of the optical properties of silicon and chromium mixed oxides deposited by reactive magnetron sputtering
(ScienceDirect, 2011-03-31)
The development of mixed-oxide thin films allows obtaining materials with better properties than those of the different binary oxides, which makes them suitable for a great number of applications in different fields, such ...

Compositional and structural properties of nanostructured ZnO thin films grown by oblique angle reactive sputtering deposition: effect on the refractive index
(IOP Science, 2012-12-17)
In this work, we report the successful growth of ZnO nanostructured films by oblique angle magnetron sputtering deposition (OAD) from a Zn target in a mixture gas of Ar/O2. The film microstructure and the surface morphology ...

Vibrational mechanics in an optical lattice: controlling transport via potential renormalization
(American Physical Society, 2012)
We demonstrate theoretically and experimentally the phenomenon of vibrational resonance in a periodic potential, using cold atoms in an optical lattice as a model system. A high-frequency (HF) drive, with a frequency ...

Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials
(Springer Verlag, 2012)
We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of nonresonant pumping and nonlinear damping. ...

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 ...
