Epoxy resins together with glass fibers had been extensively used as the core substrate in electronic applications due to its superior mechanical properties and chemical resistance. Due to its application in high heat environment, flame retardants became a required additive for the epoxy resins to prevent any flame mi…
A singly phenoxido-bridged dinuclear Cu ∥ complex, [Cu 2 (L) 2 (SCN) 2 (H 2 O)], has been obtained from a Schiff-base ligand (2-[{[2-(dimethylamino)ethyl]imino}methyl]-6-methoxyphenol), generated by condensation of o-vanillin with N,N-dimethylethane-1,2-diamine. The Cu(II) complex has been fully characterised by analy…
The effects of Li2CO3-V2O5 (LV) co-doped on the sinterability, phase compositions and microwave dielectric properties of 0.6Mg4Nb2O9-0.4SrTiO3 composite ceramics have been investigated. All specimens were prepared by solid-state reaction method and sintered at 1050-1200oC for 5h. With an amount LV addition, the densif…
The second-harmonic generation (SHG) circular dichroism in the light of reflection from chiral films of tripod-like chiral molecules is investigated. The expressions of the second-harmonic generation circular dichroism are derived from our presented three-coupled-oscillator model for the tripod-like chiral molecules.…
Starting from the wave normal tracing treatment in the Savart polariscope that relates the Jones matrix to its transmission performance, this paper establishes a simple and effective model for the Jones matrix at an arbitrary incidence in the spatial domain. Analytical expressions of all the matrix components are dete…
Flexible, reflective, bistable displays have become the focus of significant research over the past decade due to their appeal for alternative applications requiring low power, small form factor, and flexibility. Some of the first flexible displays to be offered in the market are non-traditional Reflex™ displays in un…
Single crystals of BiRe 2 O 6 of typical volume 0.03 mm 3 were grown by chemical vapor transport and characterized using room-temperature single-crystal neutron diffraction in monoclinic C 2/ c symmetry with cell parameters a = 16.1178(11), b = 4.9235(3), c = 5.5278(3) Å and β = 92.475(5) ° ( R all = 11.39 wR all = 7.…
With increasing scale of Network-on-Chips (NoCs), the power caused by long line wires between cores counts for a significant proportion of the NoCs energy consumption. Most of the study on NoCs topologies assume that interconnect wires between cores are same length and are short lines. Taking 2D 4×4 torus network as a…
Abstract This paper first describes a semi-quantitative methodology for assessing the corrosion likelihood of existing production pipelines which was developed by the Company and applied over its worldwide operations. This methodology is based on a quantitative answer to three key practical questions, requiring the in…
The crystal structure of a ferroelectric lead metaniobate containing 10 mole% barium was refined using the Rietveld method on diffraction patterns obtained using multiple diffraction techniques. Cu Kα X-ray diffraction, synchrotron diffraction, and neutron diffraction were used to provide complementary information on…
A simple combustion process has been proposed to systematically synthesize Ca3((P, V)O4)2: Eu3+. All the Ca3((P, V)O4)2: Eu3+ products were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spect rophotometer. The results indicate that Ca3((P, V)O4)2: Eu3+ phosphor particles…
A series of 1, 10-phenanthroline terbium/ polyvinyl alcohol hybrid materials with different coupling agent contents were prepared by sol-gel method. The morphology and photophysical properties were investigated. FT-IR was applied to characterize the structure of the obtained hybrid material, SEM and fluorescence spect…
The polytetrafluoroethylene (PTFE) films are deposited on glass using conventional rf-magnetron sputtering method. Their hydrophobic properties are investigated for application as an anti-fouling coating layer on the screen of displays. It is found that the hydrophobicity of PTFE films largely depends on the sputterin…
YVO4:Eu3+ red phosphor was prepared by combustion synthesis without any post heat treatment at 700 oC-900 oC, using urea, oxalate acid and metal nitrates as raw materials. The product can emit bright red light under ultraviolet light irradiation. The phase compositions and luminescence properties were studied via X-ra…
Abstract The cover picture shows the structure of a fluorescent polymer consisting of a ligand‐functionalised polylactide coordinated to Re(CO)3(phen). This polymer can passively target cancer tissue and transport the fluorescent dye to the cancer cell membranes, where it can be detected by fluorescence microscopy, wh…
YVO4:Eu3+,Ln (Ln = Bi3+, La3+, Li+) red phosphors were prepared by combustion synthesis, and effect of the Bi3+, La3+, Li+ doping ions on luminescence properties was studied. After doping with Bi3+, the emission intensity, excited by 322nm UV, decreased, but the absorption at 365nm was effectively enhanced; the bright…
Nano calcium carbonate (CaCO3) of good evenness and narrow particle size range were synthesized by controlling conditions and adding agents to improve the evenness and reduce particle surface strength. It was shown that the evenness degree was improved by all additives used, and the particle size was decreased only by…
Abstract This chapter discusses the typical compositional ranges of superalloys, the role of major base metals (iron, cobalt, and nickel), and the effects of common alloying additions. It describes how chromium, aluminum, and titanium as well as refractory elements, grain-boundary elements, reactive elements, and oxid…
This paper presents the development and implementation of a three-phase universal active filter consisting of three single-phase modules. Each single-phase module is controlled by a digital signal processor. The proposed active filter can compensate the present harmonic distortion in the voltage, as well as under and…
Ca3(VO4)2: Eu3+, Bi3+ phosphor powders were prepared by the combustion synthesis or the solid state reaction at room temperature, respectively. The phase composition, morphology and photo-luminescence of the Ca3(VO4)2: Eu3+, Bi3+ phosphors were investigated by X-ray diffraction, scanning electron microscope, and spect…
