Biocompatible Silver-containing a-C:H and a-C coatings: A Comparative Study
(SpirngerLink, 2007-04-18)
Hydrogenated diamond-like-carbon (a-C:H) and hydrogen-free amorphous carbon (a-C) coatings are known to be biocompatible and have good chemical inertness. For this reason, both of these materials are strong candidates to ...

In situ mechanical, temperature and gas exposure treatments of materials combined with variable energy positron beam techniques
(ScienceDirect, 2002-06-21)
An overview is given of the extension of the Delft variable energy positron (VEP) beam facility with equipment for in situ heating, cooling, 4-point bending, hydrogen permeation and gas ad- and absorption of bulk materials, ...

Breather collisions: A survey of recent results
(2005)
We present some results on breather collisions in DNLS lattices, with special focus on systems with saturable nonlinearity. We also review some other works concerning to collisons in FPU and Klein-Gordon lattices, proposing ...

Compositional depth profiling analysis of thin and ultrathin multilayer coatings by radio-frequency glow discharge optical emission spectroscopy
(ScienceDirect, 2006-06-20)
In most of the industrial applications of multilayer coatings, a detailed knowledge of the interlayer structure and the interfaces is needed. In comparison with standard surface analysis techniques (SIMS, XPS, AES, etc.), ...

Static and moving breathers in a DNA model with competing short–range and long–range dispersive interactions
(2001)
So far, all the studies on breathers on DNA have considered models with either short–range or long-range interaction. However, none of them have considered both kinds of interactions. When both interactions are taken ...

Space Charge Studies on Mid-voltage Cable by Thermally Stimulated Depolarization Currents in the Melting Temperature Range.
(IEEE, 2004)
In the present work, a XLPE mid-voltage cable from General Cable CO. has been studied by Thermally stimulated depolarization currents. Systematic measurements have been carried out in order to compare the conductive ...

Effect of breather existence on reconstructive transformations in mica muscovite
(2008)
Reconstructive transformations of layered silicates as mica muscovite take place at much lower temperatures than expected. A possible explanation is the existence of breathers within the potassium layer. Numerical analysis ...

Localized oscillations in nonlinear hamiltonian Klein-Gordon lattices. Breathers and Anderson modes
(2002)
There are two different sources of localization in discrete lattices: • Anderson modes in disordered harmonic lattices [1] • Discrete breathers in homogeneous nonlinear lattices [2]

Discrete breathers collisions in nonlinear Schrödinger and Klein-Gordon lattices
(2008)
Collisions between moving localized modes (moving breathers) in non- integrable lattices present a rich outcome. In this paper, some features of the interaction of moving breathers in Discrete Nonlinear Schrödinger and ...

Nano-porosity in silica reinforced methyltrimethoxysilane coatings studied by positron beam analysis
(ScienceDirect, 2003-06)
The porosity in particle reinforced sol-gel coatings has been studied. Silica particles (Ludox-TM40) are introduced into methyl silicate coatings to increase the hardness, the elastic modulus and the fracture toughness. ...
