An analytical solution to the problem of energy spectra of sputtered atoms under light-ion bombardment of plane-parallel layer is obtained. The proposed theory is based on the invariant embedding principle applied in combination with the discrete flow method. This approach provides absolutely precise fulfillment of th…
Contrary to the overall trend in the worldwide economy, 2009 actually has turned out a good year for the physica status solidi journal series. With more than 10.000 published pages, pss (a), pss (b), pss (c), and pss (RRL) continue to be major players on the stage of journals covering the entire broad spectrum of soli…
Because of power consumption increase, global warming, and limitation of installation, not only high reliability and interruption capability but also compact and light power apparatuses are needed. In this paper, E field calculation and experiment were processed to identify the influence of the shape of end shield and…
Zinc oxide thin films are becoming increasingly popular for their wide range of properties and the ability to deposit these films on organic substrates for applications such as biotemplating, OLEDs, or deposition on fabrics for functionalization purposes including power generation from the flexing and deformation of w…
Mesenchymal Stem Cells (MSC) are gaining in popularity as an experimental therapy for a number of conditions including graft-versus-host disease, Crohn's disease, myocardial infarction, etc. Most applications require that MSCs be expanded to achieve an adequate cell-dose for therapy. Prior data suggest that MSC underg…
In a recent paper, Varischetti et al. (Plasma Phys. Contr. F. 2008, 50, 105008-1–15) have found that in a slab geometry the effect of the flow shear in the field-aligned parallel flow on the linear mode stability of the ion temperature gradient (ITG)-driven modes is not very prominent. They found that the flow shear a…
The local atomic structure and surface morphology of thin semiconductor films of Ge have been studied via extended X-ray absorption fine structure spectroscopy and atomic force microscopy. The films have been obtained by thermal evaporation of a material in an ultrahigh vacuum at different substrate temperatures. The…
In this paper, by comparing among different equations of state, we would like to find one equation of state, which can be applied in wide range of pressures for fcc metals. The equations of state for fcc metals: Al, Cu, Ag have been studied with ultrasonic data. Compared with experimental DAC data, it is found that th…
A novel europium(III) complex, [Eu(C7H5O2)2(C7H6O2)2(C12H8N2)2Cl], was synthesized and characterized by elemental analysis and single-crystal X-ray determination. It crystallizes in the monoclinic system, space group Cc with a = 17.2814(16), b = 17.9421(17), c = 14.9971(14) Å, β = 101.6510(10)°, Z = 4, ρ c = 1.508 g/c…
Unified power quality conditioner is a powerful tool to settle the power quality problems. In reason of power devices technology promotion and their cost reduction, it is predicable that UPQC will attain wide spread usage. Therefore its lifetime and efficiency would become important issues. In this paper a control sys…
A 15 nm thick high temperature AlGaN nucleation layer was grown on a slightly off-orientedc-plane sapphire substrate by metal–organic vapor phase epitaxy. The evaluation of this layer by high resolution X-ray diffraction yields a nucleation with a threefold distribution of the rotational disorder within about 4° in th…
Kurzfassung Mithilfe von sogenannten Schädigungsmodellen kann das Verformungs- und Versagensverhalten von metallischen Werkstoffen beschrieben werden. Die auf der Mikrostrukturebene ablaufenden Schädigungsvorgänge werden dabei mit kontinuumsmechanischen Ansätzen beschrieben. Bei diesen klassischen Schädigungsmodellen…
The stability and size effect analysis of different isomeric structures of Mg n(n = 1–5) nanowires have been investigated by employing ab-initio approach. We have considered various geometrical structures up to five atoms to explore the minimum energy configuration. In the present study, we have calculated various phy…
Data on electron diffraction study of bismuth films during heating are presented for various partial oxygen pressures in the gas phase. The formation of bismuth oxide phases is completed in several seconds.
The luminescence excited upon the discharge of molecular gases O 2 , N 2 O, and CO onto a Zn 2 SiO 4 -Mn crystalline phosphor surface prefilled with oxygen atoms is studied. An interpretation of this phenomenon in terms of the model of acceleration of the surface heterogeneous recombination of oxygen atoms in the appe…
The magnetoresistance of and Hall effect in polycrystalline α-U in the temperature interval 4.2–77K and transverse magnetic fields B to 4T have been investigated. It is found that below 43K the Hall coefficient RH of α-uranium depends on the magnetic field. The strong temperature dependence of the RH below 43K which i…
For many decades, the international community has viewed a ban on production of nuclear weapons-usable fissile materials as a truly significant step that would bring the world closer to the dual go...
Moisture absorption behaviour of polymer matrix composites (PMCs) in humid and tropical environments is a complex phenomenon. Moisture diffusion weakens the fibre/matrix interface which leads to deterioration of mechanical properties. Hygrothermic ageing of carbon/vinylester, glass/vinylester, carbon/epoxy and glass/e…
In order to explore the functionalization of wearable fabrics for power generation, barium titanate (BTO) was deposited on nickel tape and on carbon fiber fabric employing pulsed laser deposition (PLD) methods under conditions normally not considered ideal to produce optimum ferroelectric properties, namely, at temper…
The density functional theory calculations on the manganese complex ([Mn(8-OHQ) 3 ] · CH 3 OH, 8-OHQ = 8-hydroxyquinoline) is made and its stabilization, molecular orbital composition, orbital energies, and NBO charge distribution have been investigated. The crystal structure of the complex closely resembles the optim…
