2 Abstract: The stainless steel (SS) has been used as a material for building Ultra High Vacuum (UHV) Chamber. The nano crystalline phases of SS have been identified from XRD (X-Ray Diffraction) spectra. We have also studied the surface morphology of SS with using SEM (Scanning Electron Microscopy) technique. The obta…
This paper analyzes the way in which the parameters of the reluctance synchronous motors influence the value of the electromagnetic torque in steady state. In order to do this there are presented the necessary computation relations and a series of characteristics obtained by simulation with the help of a Matlab progra…
In the long run, nuclear waste packages at the Yucca Mountain repository are likely to evolve into a combination of corroded materials mixed with relicts of intact Alloy-22 and other waste package materials. Different rates of corrosion, due to physical and chemical disturbances in the environment of the repository, w…
Neste estudo foram avaliados mecanismos citotóxicos de alguns antibacterianos usados nos tratamentos de infecções ósseas, nomeadamente vancomicina, tetraciclina, tigeciclina e metronidazol numa gama de concentrações de 0,005 μg/mL a 100 μg/mL. Relativamente à vancomicina não foi encontrada nenhuma evidência de citotox…
Techniques of dye-sensitized nanocrystalline solar cells(DSSCs) having a conversion efficiency of AM 1.5G solar light to electric power over 11 % are reported. In this paper,the fundamental structure and the principle of DSSCs are introduced and the development of key components, including nanoporous semiconductor fil…
The development of nuclear resonance (NMR) imaging techniques as a clinical diagnostic modality has prompted the need of compounds, which enhance the image contrast between normal and diseased tissue and/or indicate the status of organ or blood flow. Complexes of paramagnetic transition metal and lanthanide ions with…
This paper reviews the two main configurations of M V switchgear and advantages of both concepts in the l ight of user requirements. The paper then presents an impro ved fixed pattern design which goes beyond the requirem ents of users who specify withdrawable equipment.
We report on a study to realize solid oxide fuel cells as micro power generators burning hydrogen or eventually butane. The sputter deposited electrolyte layer of yttria stabilized zirconia (YSZ) was 200 to 400 nm thick. The membrane was supported by a nickel grid that was fabricated by electrochemical deposition. Ope…
PHBV is an important sustainable product as it is produced from renewable resources, is completely biodegradable, and can be moulded as a petrochemical thermoplastic. The mechanical behaviour and biodegradability of this semicrystalline material strongly depends on its morphology. In this article we show how the amorp…
The computations of the phonon dispersion curves (PDC) of four equiatomic K based binary alloys viz. K0.5Li0.5, K0.5Na0.5, K0.5Rb0.5 and K0.5Cs0.5 to second order in local model potential is discussed in terms of real-space sum of Born von Karman central force constants. Instead of the concentration average of the for…
ZnO nanoparticles were prepared by injecting atomized droplets of spray solution containing zinc precursor into a heated reactor. Structural properties of ZnO nanoparticles thus created were investigated using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The TEM picture showed nearly monodispers…
The natural zeolites as very effective mineral sorbents are often used for adsorption of many metals and other pollutants in the process of water purification. This study focused on the results of using the unique adsorption and chelating affinity of one of the most spread natural zeolites - clinoptilolite for reducti…
The impact of the variables was evaluated by measuring bending strength properties and comparing matched laboratory and field exposure samples. The physical test data show the positive effects of adding a buffering system to model FR compounds and the negative effects of increasing the moisture in the environment duri…
Den Grundstein für die Miba AG mit Hauptsitz in Laakirchen (Oberösterreich) legte der damals 21-jährige Franz Mitterbauer, Vater des heutigen Vorstandsvorsitzenden Peter Mitterbauer, bereits im Jahr 1927, als er die Schlossereiwerkstätte seines Lehrherrn in Laakirchen übernahm. Der Einmannbetrieb spezialisierte sich r…
The crystal electric field levels' scheme of the heavy fermion (HF) CeCu 4Si compound has been studied employing inelastic neutron diffraction (INS) and specific heat measurements. INS spectra reveal the presence of the excitation peaks at about 8.9 meV and 13 meV. The resulting levels' sequence consists of three doub…
We investigate the electrical properties of three different trilayer organic light-emitting diodes (OLEDs), one of which is based on a conventional layered structure and the others on a blended structure where an emitting layer (EML) is uniformly or stepwise mixed with an electron transport layer (ETL), Tris-(8-hydrox…
Summary: Intrathecal and/or high-dose intravenous admi nistration of methotrexate (MTX) in the treatment of ma lignancies such as acute lymphoblastic leukaemia (ALL) has been associated with cases of mild to severe neurotoxicity. The pathogenic mechanism of neurotoxicity is not clear, possibly MTX-associated biochemic…
Waveguiding properties of linear 1D arrays of metal nanoparticles have recently attracted considerable attention. For applications in nanophotonics, integrated optical circuits, etc., the dispersive properties of surface plasmon polaritons (SPPs) in such waveguides are of primary importance and have been studied exten…
Recent advances in scanning/transmission electron microscopy (S/TEM) achieved by the TEAM Project have established new benchmarks in quantitative microscopy for spatial resolution (50 pm), sensitivity (single atom detection of light and heavy elements), and measurement precision (better than 5 pm). The achievements of…
