Radiation characteristics of a wide-band dipole antenna over an electromagnetic band-gap (EBG) reflector are investigated. The mushroom-like EBG structure is used as the EBG reflector. The analysis is performed using Method of Moment. It is shown that wideband characteristics of the voltage standing wave ratio (VSWR)…
The optical properties of sol-gel spin-coated ZnO and F-doped ZnO (FZO) thin films were investigated using ultraviolet-visible and temperature-dependent photoluminescence spectroscopies. The FZO films showed on average of > 80% optical transmittance over the entire visible region, and the transmittance spectra and the…
Lead-free KNbO3single crystals and (K0.38Na0.52Li0.04)-(Nb0.86Ta0.1Sb0.04)O2.97textured ceramics were investigated as a function of temperature using Raman spectroscopy and loading dilatometry.
Magnesium single crystals of three dierent orientations were deformed by tension at room temperature to investigate the geometrical criterion resulting from the Schmid law for activation of basal and non-basal slip systems. Changes of crystallographic orientations of investigated single crystals were systematically me…
A three-dimensional bandpass frequency selective structure (FSS), consisting of a 2D periodic array of two vertically placed microstrip lines and one inserted metallic bar, is presented to realize wideband filtering response. Through analyzing the propagation characteristic, it is obtained that two substrate modes and…
High impedance metasurfaces (HIMSs) formed by interwoven conductor arrays are proposed. Bandwidth comparable with that of the basic square patches is achieved at an order of magnitude smaller unit cells. The presented structures are apt for small mobile terminals and low frequency applications.
The objective of this paper is a generalization of printed media publications and publications of polymeric insulations’ manufacturers with a view to distinguish strengths and weaknesses of polymeric insulation, summarize experience in application of polymeric insulation and if possible to observe a tendency of its fu…
Electron diffraction is used to show (for the first time) that the reverse α → γ transformation in an Fe-32% Ni during slow heating develops via the formation of an intermediate paramagnetic 9 R phase. Coarse extended lamellae form according to a shear mechanism in the central part of the temperature range of the reve…
A transient reduced order model (ROM) for electric machines based on singular value decomposition (SVD) is proposed. The ROM generation process starts with computation fluid dynamics (CFD) results of an electric machine model, from which SVD is used to calculate the approximate subspace that the temperature solution b…
In this work, we report on an innovative approach which integrates GaN-on-Diamond microstrip MMICs with a state-of-the-art microchannel cooler and provides a significant thermal advantage for high power GaN applications. Specifically, we describe efforts to develop a wide bandwidth, GaN-on-Diamond MMIC power amplifier…
The study is concerned with high-purity SnO2 and ZnO powders produced from salt solutions of corresponding metals by low-temperature hydrothermal synthesis. Fragments of SnO2 and ZnO ceramic targets formed as 1 × 8 cm bars are fabricated by dry pressing. The bars are used to form composite targets for ion-beam sputter…
The poor mechanical properties of akermanite (AKM), especially fracture toughness, limits its applications in bone tissue engineering, although it possesses favorable biological performance. In this research, silicon carbide whiskers (SiCw) are added in order to reinforce AKM scaffolds with controllable porous structu…
Atomistic modeling based on the accurate first-principles method is used to investigate the lattice parameter, elastic constant, elastic modulus including bulk modulus (B) and shear modulus (G), Poisson's ratio, and elastic anisotropy of Al, NiAl and Ni3Al under extreme condition. The elastic constants obtained from c…
Anisotype n -ZnSe/ p -InSe and n -ZnSe/ p -GaSe heterojunctions are obtained for the first time. They are grown on layered crystalline GaSe and InSe substrates by annealing in Zn vapor. It is found that these heterojunctions are sensitive to light in the near-infrared and visible spectral ranges.

Nanoscale epitaxy or nanoepitaxy for fabricating macroscopically well-aligned nanoscale heterogeneous interfaces on a Si substrate is demonstrated, combining bottom-up and top-down processes efficiently. TiO 2 sputtered in vacuum was selectively nucleated on the atomically flat surfaces of individual CeO 2 nanocubes p…

Neuronal networks cultured on microelectrode arrays (MEAs) have been utilized as biosensors that can detect all or nothing extracellular action potentials, or spikes. Coating the microelectrodes with carbon nanotubes (CNTs), either pristine or conjugated with a conductive polymer, has been previously reported to impro…
X-ray microanalyses of sub-micrometer features require that a lower accelerating voltage be used. This reduction in the accelerating voltage reduces the penetrating distance of the beam electrons and thereby reduces the analytical volume. Two general strategies have been proposed for achieving the smallest analytical…
Several decades of cumulated research evidence have proven that aggregation of beta-amyloid 42 (Aβ42) is the main cause of neuronal death in the brains of patients with Alzheimer's disease. Therefore, inhibition of Aβ42 aggregation holds great promise for the prevention and treatment of Alzheimer's disease. To this en…
