It is reported that field emission can effectively enhanced for aligned carbon nanotubes (CNTs) as field emitters when the ratio of distance between neighboring nano-tubes to the height of each individual CNT is about 2. In this paper, we proposed pillar array design of CNTs to fulfill the optimum R/H ratio (the ratio…
The design and synthesis of novel copolymers which consist of a linear methoxypoly(ethylene glycol) block and a dendrimeric poly(ester-sulfide) block with potential applications in drug delivery are described. The copolymers bear hydroxyl or alkene functional groups and were prepared via a divergent approach using rea…
The effect of the annealing temperature (390°C, 410 °Cand 430°C) on the stress relaxation of air side and tin side of ion exchanged glasses was investigated. The annealing time dependence of stress at different temperature can be well fitted by a second order exponential function. The stress relaxation rate on tin sid…
The Naval Undersea Warfare Center has funded a project to investigate the accuracy of various bolt models used to represent actual shipboard bolted connections within an analytical shock survivability assessment. The ultimate goal within this project is to develop finite element bolt representations that are not only…
The domain structure and its relation with the microstructure were studied in BST glass-ceramics with different concentration of AlF3 additive using several microscopic methods. It was shown that the increase of the AlF3 concentration led to larger grain size and smaller fraction of the glass regions. The piezoelectri…
We reported on a convenient route to synthesize rhombohedra boron nitride (r-BN) micro-rod using urea (CO(NH2)2) and sodium borohydride (NaBH4) through thermal treatment at 1300 °C. The structure, morphology, and chemical composition of the obtained samples were characterized by X-ray diffraction (XRD), scanning elect…
Discontinuities in the derivatives of a continuous refractive index profile n(z) enhance reflection, such reflection planes may be used to devise dielectric mirrors or filters. A triangular stack profile is proposed as an example.
Ba0.5CaxSr0.5-xTiO3 (BCST) ceramics, where x = 0, 0.1, 0.2, 0.3 and 0.4, were prepared by the conventional solid state reaction technique. X-ray diffraction (XRD) analysis confirmed the formation of BST perovskite phase structure besides some calcium oxide peaks for samples with high Ca content, x. Scanning electron m…
Elastic properties of wurtzite InxGa1−xN and InxAl1−xN alloys are investigated using the first principles calculations. For alloys with uniform distribution of In atoms, a Vegard-like approximation can describe the composition dependences of C12, C13, and C44 in InxGa1−xN, and C12, C13, and C33 in InxAl1−xN, whereas s…
Abstract New measurements of ion transport in the scrape‐off layer (SOL) during inter‐ELM periods are obtained from a retarding field analyzer (RFA) in the ASDEX Upgrade tokamak. The ion current density measured in the far SOL features large‐amplitude bursts associated with turbulent plasma filaments passing the RFA.…
In this study, a novel material, Z-2, 3-bis(4-(thiophen-3-yl)-phenyl) –acrylonitrile (Z-TPA), was synthesized and characterized. Optical and electrochromic properties of its homopolymer and copolymer with 3, 4-Ethylenedioxythiophene (EDOT) were investigated in details. UV–vis absorption and fluorescence spectra showed…
The crystallization in the three-component systems Rb2SO4-MSO4-H2O (M = Mg, Co, Ni, Cu, Zn) is studied by the method of isothermal decrease of supersaturation. It has been established that isostructural double compounds, Rb2M(SO4)2·6H2O (M = Mg, Co, Ni, Cu, Zn), , crystallize from the ternary solutions within wide con…
The accurate representation of the forming limit properties in the material model is very important for predicting the onset of failure. In this study, the FLCs for two dual phase steels DP780 and DP600 were experimentally obtained. The FLSCs were derived numerically by setting up stretching models in ABAQUS in which…
The compositions of Ce0.8−xSm0.2PrxO2−δ (x=0, 0.02, 0.04, 0.06) were prepared through the sol-gel route. The effect of Pr addition on the crystal structure, densification and thermal expansion of Ce0.8Sm0.2O2−δ was studied. The powder X-ray diffraction (XRD) analysis showed that all the samples exhibit a fluorite stru…
Micrometric 2D arrays of Ba(NO3)2 were spontaneously produced on a glass substrate through crystal growth induced by evaporation of water from viscous solutions containing polyvinyl alcohol (PVA). Specific trigonal microarrays were formed when the {111} face of Ba(NO3)2 was parallel to the substrate. Aligned triangles…
The great interest toward chalcogenide materials is due to the simple technology of preparation in bulk forms and thin films; good thermal and mechanical properties; transparency and photo-sensibility in the IR spectral range. These advantages determine the possibilities for potential application of these materials li…
Reduction of Si percentage in Fe-Nb-Cu-B-Si alloys known as Finemets results in 1.5 T saturation, surpassing so the standard Sirich compositions. However the other soft-magnetic properties are worse due mainly to magnetostriction and the consequences of socalled macroscopic heterogeneity. Therefore phosphorus has been…
To my wife, Elizabeth Kay Berner, for her unstinting encouragement and understanding throughout the many years of my devoting myself to my research, and for her collaboration in the writing of three books. This autobiography covers the past 55 years of my research in geochemistry. I try to show how
A new technique of atomic layer deposition (ALD) has been the first introduced to fabricate PbS-doped silica fiber, whose optical properties are measured. The fiber exhibits photoluminescence property in the wavelength range 1100-1185 nm.
