We present a method of calculation of the effective magnetic permeability of magnonic metamaterials containing periodically arranged magnetic inclusions of arbitrary shapes. The spectrum of spin wave modes confined in the inclusions is fully taken into account. Within the scope of the proposed method, we compare two a…
In this paper we give a method by computer-assistance to prove a pattern formation. As a typical model we consider two dimensional time-dependent reaction-diffusion equations with Neumann boundary conditions. For suitable system parameters we solve (approximately) the parabolic problem, hoping for some convergence to…
The need for electrical energy is growing fast as a result of the expanding world population and economic activities. On top of this the energy need of each individual is also growing. At present the growth in energy demand is not matched by the growth in energy generation because of insufficient energy production. Th…
This thesis describes a series of experiments on the control of the optical properties of the nitrogen-vacancy (NV) center in diamond, and on control of the electron and nuclear spin states associated with the NV center. The NV center is a fluorescing atomic defect center in diamond, consisting of a substitutional nit…
This letter describes a new inorganic shadow mask that has been employed for the evaporation of all-epitaxial Al/Al2O3/Al superconducting tunnel junctions. Organic resists that are commonly used for shadow masks and other lift-off processes are not compatible with ultra-high vacuum deposition systems, and they can bre…
We show that the Cauchy--Born model of a single-species 2-lattice is second order if the atomistic and continuum kinematics are connected in a novel way. Our proof uses a generalization to 2-lattices of the point symmetry of Bravais lattices. Moreover, by identifying similar symmetries in multi-species pair interactio…
Les critères de localisation et d’endommagement sont généralement basés sur un cadre dissipatif et ce travail s’intéresse aux couplages thermomécaniques accompagnant les micromécanismes de déformation. Il repose en partie sur des données expérimentales obtenues précédemment dans le laboratoire par Bodelot pour un poly…
Polymer brushes have been shown in many investigations to be one of the most powerful systems to control interfacial properties [1-11]. Brushes can be used to coat colloidal particles, thereby strongly enhancing the colloidal CONTENTS 7.1 Introduction ...................................................................…
As a method for mechanical surface treatment, shot peening has been widely used to improve the fatigue strength of materials. However, the influence of residual stresses introduced by shot peening depends on their stability. The stability of residual stresses during fatigue may be studied in two stages: the first cycl…
In the vast literature that covers the subject of polymer brushes, one may find numerous studies concerning brush formation and properties on flat surfaces. Since the introduction of the concept, polymer brushes have been studied traditionally on flat macroscopic surfaces due to the applicability of well-established e…
To improve flame retardation of poly(ethylene terephthalate) (PET) against burning, resorcinol bis(diphenyl phosphate) (RDP), phosphorous containing flame retardant, was incorporated into PET backbone by radical reaction pathway. Radical endcapping of PET with RDP was confirmed by spectroscopic and thermal analysis. F…

Stimuli-responsive polymers attract an ever-growing interest for the design of “smart” surfaces or interfaces, where properties (surface energy (Yakushiji et al. 1998), adhesion (Jones et al. 2002), friction (Ikeuchi et al. 1996, Chang et al. 2007)) can be strongly altered upon application of an external stimulus, suc…
Surface properties of substrates are among the most important contributors to their applications, especially when the application involves the interaction of the surfaces with foreign media or entities. As an example, the surface properties are of tremendous importance when the chromatographic separations of proteins,…

The Integral spacecraft, a Gamma, X-Ray and optical telescope operated by ESOC since 17/10/2002, is in a highly elliptical high inclination orbit and experiences a perigee passage through the Van Allen radiation belts every 3 sidereal days. As the high radiation experienced during these passages would damage the instr…
In uniform and isotropic systems the three-dimensional pair distribution function and the structure factor can be restored from two-dimensional observations of the sliced volume with finite thickness without scanning along the third dimension. By numerically simulating such observations of a known system, it is explic…
In the title compound, [PtCl(2)(C(9)H(7)N)(2)]·CH(3)NO(2), the Pt(II) cation is four-coordinated in an essentially square-planar environment by two N atoms from two quinoline ligands and two Cl(-) anions. One of the nearly planar quinoline ligands [maximum deviations = 0.042 (6) and 0.018 (7) Å] is almost perpendicula…
Novel cationic fluorinated polyacrylate latex was synthesized and characterized using Infrared spectrum (IR). Then it was utilized as waterproofing agent to treat wet blue leather and the effects of various parameters, such as dose of fluorinated acrylate latex, processing time, temperature, etc., on hydrophobic prope…
