Abstract In this paper, an advanced optical thin film structure, which can be used for fabricating multidomain display is introduced. It is composed of multilayer patterned birefringent thin films, of which each thin film is formed by a liquid crystal (LC) polymer layer with spatially varying optical axes controlled b…
Abstract Colorless single crystals of TiTa2O7 and TiNb2O7 are prepared by melting stoichiometric mixtures of Nb2O5 or Ta2O5, and TiO2 at 1973 and 1873 K, respectively.
Induced voltages by indirect lightning cause faults, damage to equipment and malfunctions to electric power systems, compromising the quality, continuity and reliability of the electrical energy supply. In this context, research development is crucial to improve lightning protection procedures, especially for electric…
The phosphorescence decay kinetics of triplet excitations being energy donors in matrix-isolated donor—acceptor pairs has been analyzed using numerical simulation. It has been noted that the inclusion of states of donor—acceptor pairs in which both molecules are in the triplet state during energy transfer can have an…
It is found that if thermoelectric material has a structure in the form of alternating regions with low and high thermal conductivity and electrical conductivity, and thus the width of the regions with low thermal conductivity and electrical conductivity does not exceed the mean free path of electrons in them, then th…
This paper studies the behavior of the corona effect in dry air and coaxial configuration for different pressure values. The study is conducted in a system of four parallel-connected coaxial cylinders placed inside a controlled pressure chamber. During the tests, DC current is measured through the coaxial system for v…
High-speed mechanical agitation is commonly used to produce microbubbles and droplets for ultrasound imaging and therapy. This technique results in a high concentration (~1010 particles/mL) of polydisperse particles (less than 400 nm to greater than 15 μm in diameter). Differential centrifugation has been used to isol…
A therapeutic method named Myocardial Cavitation Enabled Therapy aiming at noninvasive cardiac tissue reduction is modeled here. Sparsely distributed microlesions induced by ultrasound cavitation of contrast agents are hypothesized to cause myocardial shrinkage. The objective is to model lesion formation based on the…
In this study, a hard-grade paving asphalt with a penetration, of 10/20 (0.1 mm) and a limestone aggregate were used to produce a hard-grade asphalt mixture AC - 20 (HaGAM). Basic performance tests, such as a wheel rutting test at 60°C, a three-point beam bending test at −10°C, and an indirect tensile strength test du…
Abstract In this paper, we report efficiency enhancement of indium phosphide (InP) quantum dot‐based light‐emitting diodes (QD‐LEDs) using polyethylenimine (PEI) surface modifier. Adapting solution processed PEI layer on top of the aluminum‐doped zinc oxide (Al:ZnO) nanoparticle (NP) layer, the leakage current of inve…
Going beyond traditional cavity-concepts, recently conceived nanolasers employ plasmonic resonances for feedback, allowing them to concentrate light into mode volumes that are no longer limited by diffraction [1]. The use of localized surface plasmon resonances as cold-cavity modes, however, is only one route to lasin…
With the integration of cores increasing, the on-chip-network (NoC) latency and the throughput are getting worse in traditional structures. This paper proposed a novel parameter-based on the hierarchical mesh interconnected NoC (PHMNoC) to improve the integration and performance. We use structural parameters and cross…
The properties of BiFeO 3 /intermediate layer/substrate structures fabricated by radio-frequency magnetron sputtering at low temperatures (450°C) and by deposition on substrates and intermediate layers between the substrate and the BiFeO 3 film have been investigated. In the structures, glass substrates or commercial…
Transcranial focused ultrasound therapy is becoming a viable tool for treatment of brain related disorders. The technique has been used for treatment of essential tremors and chronic neuropathic pain with good results. In addition, the technique has a broad scope of potential applications including: tumor ablation, lo…
We demonstrate spatial and temporal control over metamaterial properties using coherent interactions of beams of light on plasmonic metasurfaces. This is illustrated by all-optical logical operations between two images.
Abstract A thin polarized‐light emitting film is fabricated by aligning nanorods in an electric field and subsequent polymerization. A polarization ratio of 0.60 is obtained with this method. The thickness of the film is in the order of a few micrometer, and the method is compatible with large‐scale processing on chea…
Back Cover: Extended molecular dynamics simulations for G = 4 neutral and protonated PAMAM-EDA in water and its subsequent coarse-graining permit an accurate analysis of conformational properties. The trajectories are used to compute binary interactions between bead-like dendrimers. These interactions are shown to obe…
The present paper reveals the seasonal change of the species composition and the population density of the freshwater ostracodes living in the biotpe of the University Museum of the University of the Ryukyus. The two sampling localities, A and B, are respectively situated in the pond in imitation of a rice paddy and i…
The effect of uniform pressure on the activation parameters of the kinetic equation that describes the exponential dependence of the steady-state creep rate and the lifetime of polycrystalline metals on stress and temperature is estimated. It is shown that, under pressure, the parameters that determine the behavior of…
The recent renewed interest in diffraction gratings as mirrors for vertical-cavity surface-emitting lasers (VCSELs) stimulated the development of fast and accurate full-wave simulators. In fact, their modeling requires large sets of scattering analyses, which can be effectively carried out by means of mode-matching te…
