In order to facilitate the circuit design and simulation at extreme temperatures, APEI, Inc. fully characterized a custom-built SiC VJFET transistor at temperatures up to 525 °C and built a Spice model based on the characterization data. The temperature effects were also formulized in this Spice model to ensure its un…
Abstract Dibenzotetrathiafulvalene (DBTTF) analogs containing fused thiophene spacers were synthesized and characterized by cyclic voltammetry, UV–vis absorption spectroscopy, quantum chemical calculations, single-crystal X-ray analysis, overlap integral calculations, field-effect transistor (FET) characteristics, X-r…
Reticle quality and the capability to qualify a reticle are key issues for EUV Lithography. We expect current and planned optical inspection systems will provide inspection capability adequate for development and production of 2X HP masks. We illustrate inspection technology extendibility through simulation of 193nm-b…
Nanocrystalline Bi5Ti3FeO15 layered perovskite exhibiting Aurivillius phase was synthesized by polymerized complex (PC) method and investigated for its physico-chemical as well as optical properties. The crystallization of Bi5Ti3FeO15 synthesized by PC method was found to occur in the temperature range of 800-1050 deg…
This article presents an original method for the theoretical analysis of the intensity radiated by a dielectric waveguide with rough walls. The method is based on Maxwell's equations under their covariant form written in nonorthogonal coordinate systems adapted to the geometry of the waveguide. The solutions are found…
Abstract The structural changes of three Cu clusters containing 51–53 atoms during their melting processes have been studied by employing molecular dynamics simulations. The local structures in the atomic density shells are presented according to the pair index of Honeycutt and Andersen. Structural transformation temp…
In this article, using Kinetic Monte simulations on super-lattices, we study the evolution of extended defects during epitaxial growth. Specifically we show that, in the case of misoriented, close-packed substrates, a single-layer stacking fault can either extend throughout the entire epilayer (i.e. extended from the…
To evaluate the binding characteristics of [(3)H]Ro15-4513 with the central benzodiazepine (BZ) receptor, inhibition experiments of [(3)H]Ro15-1788 and [(3)H]Ro15-4513 were performed both in vitro and in vivo, using two BZ ligands, flunitrazepam (FNP), and ethyl-β-carboline-3-carboxylate (β-CCE). FNP inhibited the bin…
Understanding electronic communication among interacting constituents of multicomponent molecular architectures is important for rational design in diverse fields including artificial photosynthesis and molecular electronics. One strategy for examining ground-state hole/electron transfer in an oxidized tetrapyrrolic a…
We present a multitechnique approach to study the detailed chemical and magnetic structure of uranium/gadolinium multilayers. At low temperature the saturation magnetization is found to be $\ensuremath{\sim}60\mathrm{%}$ of that of bulk gadolinium. We address this problem, which is found in many other multilayers and…
With H2O-polyols (glycerol, ethylene glycol and polyethylene glycol 400) mix-solvent as media in the NaCl-NaOH-NaNO3 electrolytic system, we developed a simple and efficient electrochemical route for the synthesis of Cu2O nanocrystals with different morphology. The SEM results indicated that electrolytic media and cur…
Abstract The synthesis of polypyrrole (PPy)/AgCl nanocomposites with their size ranging around 70–100 nm are achieved by using magnetic ionic liquid as the oxidant in the interface polymerization system. The interface polymerization leads to the formation of uniform and unaggregated nanocomposites with a relatively na…
Ruthenium(II) and palladium(II) complexes [Ru(DMSO)(L)Cl2] and [Pd(L)Cl]Cl, where L = 2,6-bis(pyrazol-1-yl)pyridine (bpp) or 2,6-bis(3,5-dimethylpyrazol-1-yl)pyridine (bdmpp) have been synthesized. All complexes were characterized by elemental analysis, IR, 1H NMR, UV-Vis, and cyclic voltammetry measurements.
Far infrared (FIR) is becoming more widely accepted within the automotive industry as a powerful sensor to detect Vulnerable Road Users like pedestrians and bicyclist as well as animals. The main focus of FIR system development lies in reducing the cost of their components, and this will involve optimizing all aspects…
Nanocrystalline nickel matrix composites reinforced with the nanosized ceria particles have been synthesized by cathodic pulsed electrodeposition. The reinforcement is synthesized by the high energy ball milling (HEBM) technique. Both the reinforcement and composites have been characterized by XRD, TEM and SEM coupled…
We prepared a photocatalyst using diatom frustules by the liquid phase deposition (LPD) method. Purified native frustules were reacted with boric acid (H3BO3) and ammonium hexafluorotitanate ((NH4)2TiF6) in order to cover the frustule surface with a TiO2 film. Scanning electron microscopy (SEM) observation revealed th…
Focused electron beam induced processing (FEBIP) of volatile organometallic precursors has become an effective and versatile method of fabricating metal-containing nanostructures. However, the electron stimulated decomposition process responsible for the growth of these nanostructures traps much of the organic content…
A generalized Ginzburg-Landau equation describing dissipative solitons dynamics in negative-refractive-index materials is derived from Maxwell equations. This equation having only real terms with opposite sign differs from the usual Ginzburg-Landau equation for positive-refractive-index media. A cross-compensation bet…
In this article, the design aspects of a new digital differential relay for power transformer protection to recognize inrush currents are proposed. The relay design is based on a percentage differential characteristic combined with an extended magnetizing inrush restraint module, which is implemented by a fuzzy infere…
Polarons---electrons coupled with lattice vibrations---play a key role in transport and optical properties of many semiconductors. Here, we calculate the energy spectrum and thermopower of Fr\"ohlich polarons confined to a potential well as a function of the well thickness. We show that the polaron mass enhancement in…
