Indium Tin Oxide (ITO) thin films on Polyethylene Terephtalate (PET) substrate were prepared by Roll-to-Roll sputter system with targets of 5 wt% and 10 wt% $SnO_2$ at room temperature. The influence of the chromaticity (b*) and transmittance properties of the ITO Films were investigated. The ITO thin films were depos…

Abstract Der Einsatz von Aluminiummatrix‐Verbundwerkstoffen (AMC) in Strukturbauteilen erfordert geeignete Fügetechnologien. Ein wichtiger Aspekt dabei ist die Erhaltung des eingestellten Eigenschaftsprofils der Verbundwerkstoffe während des Fügeprozesses. Besonders kritisch ist die thermische Belastung des Grundwerks…

Abstract From the application point of view, the most interesting compositions in the lead zirconate titanate solid solutions, PbZrxTi1-xO3 (PZT), are those near the centre of the phase diagram, where tetragonal and rhombohedral phases are separated by a boundary nearly independent on temperature. The composition of t…
Improvements in torque at low currents using a rotor with spiral sheets are analyzed. Several rotors and stators have been built combining different constructive and mechanical characteristics of the related elements: inertias, constructive materials, geometrical shapes of the sheets and geometrical disposition of the…
Transformations of the carbon-monoxide adsorption layers on metallic nanosystems including group VIII metals are studied with the use of Fourier-transform infra-red (FTIR) spectroscopy. Depending on the experimental conditions, not only the state of the chemisorption layers, but also the surface structure of the syste…

An array of micro/nano structures have been obtained by laser surface treatment on sintered LaB6pellets employing a picosecond pulsed Nd: YAG laser at a pressure ~1times10-3mbar. The x-ray diffraction pattern of the laser treated pellet shows a set of well defined diffraction peaks, indexed to the cubic phase of LaB6…

In this study, self-assembled alternating film using poly(diallyldimethylammonium chloride) (PDDAC) and meso-tetrakis(4-carboxyphenyl)porphyrin (MTCP) was prepared as a multilayer deposition on glass substrate. This preparation technique for dye deposition may provide new feasibilities to achieve the manufacture of ul…
There has been a lot of effort to make Silicon optically active. In this work we examine two methods of generating nanocrystals of Silicon from bulk fragments. This approach of ours allows us to play with the shape of the nanocrystals and therefore the degeneracy of the conduction band minimum. We go on to examine whe…
Selective enhancement and suppression of the photoluminescence arising from Si0.5Ge0.5/Si multiple quantum wells by photonic crystals (PCs) have been demonstrated. The formation of the stop band in PCs is designed to be a filter as well as a reflector. It is found that the self-assembled PCs are able to selectively en…

It has been experimentally established that the sign of the change in the efficiency of electromagnetic-acoustic transformation under elastic tension is determined by the sign of the saturation magnetostriction and depends on the magnetic state of a ferromagnet. It is shown that, after annealing, as a result of relaxa…
Properties of photoluminescence and Förster energy transfer dynamics based on an organic pyridium salt trans-4-[p-(N-Hydroxyethyl-N-methylamino)Styryl]-N-methylpyridinium iodide (ASPI) and organic small molecule Alq3 in PMMA polymeric thin films are investigated by steady-state and time-resolved fluorescent spectra as…
