Optically active luminescent perylene thin films deposited by plasma polymerization
(American Chemical Society, 2009-01)
This work reports about the preparation of plasma polymerized thin films of perylene with thicknesses ∼30−150 nm and their characterization by different methods and the analysis of their optical properties. Highly absorbent ...

Discrete solitons in nonlinear Schrödinger lattices with a power-law nonlinearity
(2009)
We study the discrete nonlinear Schrödinger lattice model with the onsite nonlinearity of the general form, |u|2σu|u|2σu. We systematically verify the conditions for the existence and stability of discrete solitons in the ...

Solitons for the cubic-quintic nonlinear Schrödinger equation with time and space modulated coefficients
(2009)
In this paper, we construct, by means of similarity transformations, explicit solutions to the cubic–quintic nonlinear Schrödinger equation with potentials and nonlinearities depending on both time and spatial coordinates. ...

Discrete breathers in a forced-damped array of coupled pendula: modeling, computation, and experiment
(2009)
In this work, we present a mechanical example of an experimental realization of a stability reversal between on-site and intersite centered localized modes. A corresponding realization of a vanishing of the Peierls-Nabarro ...

Environmental modelling in the Gulf of Cadiz: Heavy metal distributions in water and sediments
(Elsevier, 2009)
The Gulf of Cadiz (GoC) connects the Atlantic Ocean and the Mediterranean Sea. An environmental study of the GoC is carried out through numerical modelling. First, a 3D baroclinic model is used to obtain the residual circulation ...

Electrical characteristics of mixed Zr–Si oxide thin films prepared by ion beam induced chemical vapor deposition at room temperature
(Elsevier, 2009)
Mixed Zr–Si oxide thin films have been prepared at room temperature by ion beam decomposition of organometallic volatile precursors. The films were flat and amorphous. They did not present phase segregation of the pure ...

Models for radioactivity dispersion assessments in Andalusian coastal waters: Gulf of Cádiz and Alborán Sea
(EDP Sciences, 2009)
Rapid response models for the assessment of the consequences of a radioactive spill in the coastal waters of Andalusia (south of Spain) have been developed. These waters comprise the Gulf of Cadiz, GoC, (Atlantic Ocean) ...

Characteristic times in the English Channel from numerical modelling: supporting decision-making
(IOP Science, 2009)
A numerical model that simulates the dispersion of radionuclides in the English Channel has been applied to study the dispersion of conservative and non-conservative radionuclides released from the La Hague nuclear ...

Occupational dosimetric assessment (inhalation pathway) from the application of phosphogypsum in agriculture in South West Spain
(Elsevier, 2009)
Phosphogypsum (PG) has been traditionally applied as Ca-amendment in saline marsh soils in SW Spain, where available PG has 710 ± 40 Bq kg−1 of 226Ra. This work assesses the potential radiological risk for farmers through ...

Driven and damped double sine-Gordon equation: The influence of internal modes on the soliton ratchet mobility
(2009)
This work studies the damped double sine-Gordon equation driven by a biharmonic force, where a parameter λ controls the existence and the frequency of an internal mode. The role of internal oscillations of the kink width ...
