Magnetic gears have attractive features such as low acoustic noise and maintenance-free operation in comparison with conventional mechanical gears. Planetary type magnetic gears, especially, have higher transmission torque than the other types. Therefore, the magnetic gears are expected to be put into practical use. T…
This paper presents a Single-Phase Active Conditioner, which primal function is regulate load voltage, thus protecting the most sensitive loads from sags, swells, flicker and voltage harmonics. It is constituted by two back-to-back H-bridge converters. One regulates load voltage, the other DC-link voltage. This paper…
Under an unbalanced load 2nd harmonic DC link and 3rd harmonic at AC input current of a shunt APF appear due to the fundamental negative frequency load current. These low order harmonics can cause a series of high order harmonics at both of AC and DC sides. In this paper a new control method is presented to eliminate…
The machine under study is a surface-mounted outer rotor permanent magnet (PM) synchronous machine with concentrated windings, which is integrated in a flywheel of a diesel engine. The main objective of this work is to build an accurate nonlinear transient finite element method (FEM) model coupling to circuit model an…
The frequently used biomaterial in hard tissue replacement, such as dental and orthopaedic implants, is titanium. (Ball et al., 1996; Hook et al., 2002a; Huang et al., 2003; Imamura et al., 2008; Jones et al., 2000; Walivaara et al., 1994; Yang et al., 2003) These kind of biomaterial applications made of titanium are…
This work presents the production and characterization of thin films produced by RF Magnetron Sputtering technique for applications as high-k materials. RF co-sputtering was used for deposition of amorphous films on silicon substrates. Targets of 85.5TeO2-14.5ZnO (in wt.%) and bulk gold with purity of 99.99% were RF s…
Ti3O5 nano- and microfibers were obtained via annealing of C-doped TiO2 thin films aiming at solar cell electrodes and photocatalysis applications. 1.5wt% and 3.0 wt% carbon-doped TiO2 films were deposited by e-beam evaporation and were annealed for 120min at 700oC, 900oC and 1000oC in wet nitrogen (0.8%H2O). The film…
Stochiometric reaction of salicylaldoxime and tantalum or niobium ethoxide in toluene at room temperature resulted in formation of [M 2 O(C 7 H 5 NO 2 ) 2 (C 2 H 5 O) 4 ], M=Ta and Nb which were crystallized from CH 2 Cl 2 at −5 °C and characterized by spectroscopic techniques. The molecular structures of [Ta 2 O(C 7…
Microstructure of Si1-xCx films grown epitaxially onto Si wafers was studied. Clusters formed by Si and interstitial carbon were observed in Si1-xCx films by transmission electron microscopy. It was found that the cluster size increases with the total carbon content. Electron holography has determined that clusters ar…
We measured the density dependence of both the photoluminescence (PL) spectrum and the PL lifetime of CdSe/ZnS core-shell colloidal quantum dots (QDs) from 0.01 to 10.0 nmol/ml at room temperature. We found that the PL lifetime increased drastically while the PL spectrum changed slightly with an increase in the densit…
The crystal structures of the isostructural title compounds poly[(μ-benzene-1,4-dithiolato)dithallium], Tl(2)(SC(6)H(4)S), and poly[(μ-benzene-1,4-diselenolato)dithallium], Tl(2)(SeC(6)H(4)Se), were solved by simulated annealing from high-resolution synchrotron X-ray powder diffraction. Rietveld refinements of an init…
Nowadays, hydorxyapatite (HA) is widely used as bioceramics in reconstructive surgery, in dentistry and as drug delivery materials due to the good biocompatibility and osteoconductivity [Hench, 1998]. One of the limitations for the usage of these materials is their low mechanical strength. Thus, many researchers focus…
We present a multiple-scattering method to study the dispersion of multilayer honeycomb arrays of metallic nanoparticles. Three types of stacking are considered. It is shown that the energy spectra for these multilayer photonic structures strongly depend on the distances between the layers, stacking number of layers,…
The gas-phase reaction mechanism between palladium monoxide and methane has been theoretically investigated on the singlet and triplet state potential energy surfaces (PESs) at the CCSD(T)/AVTZ//B3LYP/6-311+G(2d, 2p), SDD level. The major reaction channel leads to the products PdCH(2) + H(2)O, whereas the minor channe…
BACKGROUND: Successful protein structure prediction requires accurate low-resolution scoring functions so that protein main chain conformations that are close to the native can be identified. Once that is accomplished, a more detailed and time-consuming treatment to produce all-atom models can be undertaken. The earli…
Using grand canonical Monte Carlo simulation we show, for the first time, the influence of the carbon porosity and surface oxidation on the parameters of the Dubinin-Astakhov (DA) adsorption isotherm equation. We conclude that upon carbon surface oxidation, the adsorption decreases for all carbons studied. Moreover, t…
Studies in recent years have focused mainly on strain mediated magnetoelectric (ME) effects in magnetostrictive-piezoelectric composites. This report is on resonance ME effects in a piezoelectric bimorph. The effect arises due to combination of piezoelectricity and the Ampere force on the sample that carries an ac ele…
The use of survivinT34A mutant targeted disruption of survivin, the strongest inhibitor of apoptosis protein overexpressed in tumors, has proved a promising strategy for advanced cancers. However, hyperthermia, as a cytotoxic enhancer, regularly activates the expression of survivin to counteract the heat-induced antit…
This paper investigates the various aspects of designing and exploiting a flyback type of regenerative voltage equalizer circuit for supercapacitor stacks consisting of multiple cells. The impact of circuit parameters (magnetising inductance, peak current), operating modes (constant switching frequency or constant pea…
. By comparing the two-state and a three-state unfolding processes of proteins, the order of the unfolding free energy was always inconsistent with the order of stability observed. This raises the question about the accuracy of the evaluated unfolding free energy values of three-state models. In this chapter, the line…
