The selection and design of motor for electric and hybrid vehicle is very important as the motor in this application should posses high power density, higher efficiency, fit in to limited space, and supreme heat removal capacity. One of the better selection for this kind may be an axial flux brushless DC motor. In thi…
New magnetic structures such as multilayer systems of magnetic nanoislands being alternating layers of nanoislands of various magnets have been proposed. The electric, magnetic, and magnetooptical properties of the systems have been studied. The magnetoresistance of ∼2% related to the anisotropic effect has been revea…
A method of making transition metal oxide materials that result in resistive switching properties stable over time and temperature is described. We have developed an ultra low temperature (≤450°C) process for carbonyl ligand modified NiO thin films based on the chemical solution deposition (CSD) for correlated electro…
Abstract Finite element analyses are performed in order to determine the effective thermal conductivity of closed‐cell Alporas® foam and open‐cell M‐Pore® sponge. The investigated finite element models are based on high resolution micro‐computed tomography images. The complex structures of the real materials are very…
The application of high-dielectric-constant (k) materials, e.g., Si3N4, ZrO2, and HfO2, to localized surface plasmon resonance (LSPR) excited by a Au nanoparticle structure has been investigated and simulated for the enhancement of light absorption in Si-based thin film solar cells by using Mie theory and three-dimens…
Treatment of N-phenyl- p-phenylenediamine and two equivalents of aniline with potassium dichromate in hot water acidified with a small amount of sulfuric acid gives 3-phenylamino-5-phenyl-7-aminophenazinium sulfate (pseudo-mauveine). The oxidation of N-phenyl- p-phenylenediamine and o-toluidine with potassium dichroma…
In our experiment the intermetallic layer (IML) formation during Infrared (IR) and Vapour Phase (VP) soldering was investigated. A testboard was designed, onto which fifty pieces of 0603 (1.5 × 0.75 mm) size chip resistors were mounted. For the soldering, profiles with different Qη factors (750, 1000, 1250 s°C) were s…
As flip chip packages continue to migrate to Pb-free solder and micro-bumping (μbump) for 3D IC stacking, achieving high reliability with reduced dimension and concurrent increase in current density has become one of the major challenges for microelectronic packaging systems. In this study, the electromigration (EM) p…
The authors have focused attention on an outer rotor permanent magnet vernier machine, ORPMVM, as a high-efficiency in-wheel machine. A general PMVM has two characteristics: generating a large torque in a lower speed, the torque per current is larger. These characteristics are suitable for a directly driven in-wheel m…
The dependence of transistor characteristics on grain boundary (GB) position in short-channel ZnO thin film transistors (TFTs) has been investigated using two-dimensional numerical simulations. To simulate the device accurately, both tail states and deep-level states are taken into consideration. It is shown that both…
The carrier recombination processes in Cu(In1-x ,Ga x )Se2 (CIGS) thin films were investigated by time-resolved microscopic-photoluminescence (µ-PL) measurement at room temperature. For films with x = 0.45, the spatial distribution of the donor–acceptor pair luminescence is much larger than the grain size. The PL deca…
BACKGROUND: The objective of this study was to compare the transfection efficiency of anionic liposomes coated with polyethylenimine (PEI) with that of PEI and Lipofectamine 2000(™) using the plasmid DNA encoding green fluorescent protein in a human hepatoma (Huh7) cell line. METHODS: Factors affecting transfection ef…
This paper deals with an innovative via-last TSV polymer filling process dedicated to straight (non-slopped), high aspect ratio (2:1 to 5:1) TSV, partially filled with copper. New polymers were investigated for this purpose. Firstly, the need for a polymer filling process is pointed out. Potential reliability issues a…
The aim of this paper is to compare the performances of the three-parameter sine-fit (3PSF) and the four-parameter sine-fit (4PSF) algorithm when a sine wave corrupted by a Gaussian noise is analyzed. Algorithm accuracy is evaluated by means of the expected sum-squared fit error and the normalized frequency required b…
The Proton Exchange Membrane Fuel Cell (PEMFC) is being investigated as an alternate power source for various applications as transportation and emergency power supplies. Fuel cell systems are characterized by high costs and complex auxiliary devices. For this reason, a fuel cell emulator can be used as a suitable and…
We propose the η-carbide–type correlated-electron metal Fe 3 Mo 3 N as a new candidate for testing geometric frustration in itinerant-electron magnets. In this compound, ferromagnetism is abruptly induced from a non-magnetic non–Fermi-liquid ground state either when a magnetic field (∼14 T) applied to it or when it is…
In tests with Hele–Shaw cells containing silica sand, O 2 profiles were measured after formation of a capillary fringe (CF) with a nutrient broth, that was inoculated with Pseudomonas putida. After 7 d, the CF became anaerobic up to 2 cm above the water level. Within the next 3 cm at decreasing water saturation, the O…
We present our most recent developments in 4H-SiC DMOSFETs. A 4H-SiC DMOSFET with an active area of 0.1 cm2showed a specific on-resistance of 3.7 mΩ-cm2with a gate bias of 20 V, and an avalanche voltage of 1500 V with gate shorted to source at 25°C. A threshold voltage of 3.5 V was extracted from the DMOSFET, and a su…
This paper presents a novel reconfigurable sensing scheme with the flexibility to change reading precision of analog resistance levels for MLC PCM. A 2Mcell PCM chip was fabricated in 90nm CMOS technology and was tested. Operating at 8-bits precision (adequate for 7b/cell PCM i.e., 128 resistance levels), read access…
GaN Super Heterojunction Field Effect Transistors (Super HFETs) based on the polarization junction (PJ) concept are demonstrated on Sapphire substrates.
