We present the comparative measurements of the angular dependence of the anisotropic magnetoresistance (AMR) of magnetite (Fe3O4) films on MgO(001) nonvicinal and vicinal substrates (2.86° miscut along the ⟨100⟩ direction). The AMR behavior for current parallel and perpendicular to the direction of step edges is quite…
Abstract A new method based on the online measured electrical conductance is presented for the characterization of the kinetics of dispersion of organoclay in a polar rubber matrix during melt mixing. The charge carriers available in the clay galleries become released as a result of the dispersion processes; thus, the…
In this work, we have studied the influence of seed layer on the microstructure of the Cu underlayer and its effect on the structure and magnetic properties of subsequently deposited SmCo5 films. Our investigation concentrated on the thickness effect of Ta seed layer. Our study has shown that a smooth Ta seed layer ca…
Acid functionalized multiwall carbon nanotube ink was deposited onto carbon fiber fabric via dip coating. Repeatable staircaselike current-field curves were observed in the field emission data. These atypical curves are attributed to resonant tunneling through localized surface states in a quantum well structure, whic…
ZM6 magnesium alloy was prepared by solid recycling process. Effect of heat treatment on microstructure and mechanical properties of the alloy was investigated. Cold pressing was employed to prepare extrusion billets of ZM6 chips, then the billets were hot extruded at 773 K with an extrusion ratio of 25:1. During hot…

Crystallizing solutions of proteins often contain various nonelectrolyte additives that arise from the purification process of proteins or from the reagents employed in the screening kits. Currently, limited knowledge exists about the influence of these additives on the mechanisms underlying the crystallization proces…
Pb ( Zr , Ti ) O 3 (PZT)-based ternary compound thin films, 0.06PMnN-0.94PZT(50/50) (PMnN-PZT), are deposited on Si-based heterostructures by rf magnetron sputtering system. The intrinsic PZT(50/50) thin films are also deposited on the same kind of substrates for comparison. The PMnN-PZT thin films show the similar po…
The properties of silver and aluminium wire-grid polarizers are examined in the volume plasmon frequency region where the transmittances of field with polarizations parallel and perpendicular to the grid lines are reversed with respect to their behavior outside the plasma region. Analysis of the behavior is conducted…
Cd 0.1 Zn 0.9 Se quantum dots with fluorescent emission centered on 614 nm were covalently coupled to a 11-amino-1-undecanethiol monolayer self-assembled on a gold surface. A 594 nm laser was used to excite surface plasmons in the gold film and the resulting surface plasmon enhanced fluorescence of the quantum dots wa…
The electronic Raman scattering of bulk graphite at zero magnetic field reveals a structureless signal characteristic of a metal. For $B\ensuremath{\gtrsim}2\text{ }\text{T}$, several peaks at energies scaling linearly with magnetic field were observed and ascribed to transitions from the lowest energy Landau level(s)…
Deformation twinning has been observed in room-temperature rolled nanocrystalline Ni. The growth of the deformation twins via the emission of partial dislocations from a grain boundary has been examined in detail. Partial dislocations on neighboring slip planes may migrate for different distances and then remain in th…
Abstract A new method for the compensation of matrix effects in biosensing experiments referred to as reflective interferometric Fourier transform spectroscopy (RIFTS) has been developed recently [1]. It employs a porous silicon sensor comprised of two porous silicon layers stacked one on top of the other. The structu…
La 2 − x R x CuO 4 (R: Pr, Y, Nb) polycrystalline ceramics have been prepared by a spark plasma sintering process. Analysis of the microstructure and phase composition shows that pure La 2 CuO 4 ceramics with a high density can be obtained, and no impurity phases appear. All the samples exhibit a metal–semiconductor t…
We present a quantitative study of 180° domain wall motion in epitaxial BiFeO3 (111) films, which can be treated as a nearly ideal single-domain environment. The domains were dynamically written by applying voltage pulses and examined by the piezoresponse force microscope technique. A transition of domain growth behav…
A simple biomolecule-assisted hydrothermal approach was developed to synthesize ZnSe nanoparticles in this article. As-prepared zinc selenide was characterized by XRD, TEM, FTIR and UV-vis technologies. During the whole procedure, L-glutamic acid acted not only as complexing and capping agent, but a bridging agent bet…
The purpose of this work is to study the self-assembling of some synthesized thiol surfactants namely (mercaptopropane-, mercaptohexane-, mercaptooctane-, and mercaptodecane sodium sulfonate) on the fabricated gold nanoparticles. The self-assembling of these surfactants on gold nanoparticles characterized using differ…
Abstract Eine Helix findet Nachahmer : Die Chiralität einer helicalen, propellerähnlichen Micelle wurde von funktionellen Gruppen auf der Oberfläche einer Mesopore von chiralem mesoporösem Siliciumdioxid übernommen. Eine derart eingeprägte supramolekulare Chiralität kann auf das Natriumsalz von Poly(propiolsäure) und…
We report on the observations of room-temperature ferromagnetism and ferroelectricity in the epitaxial thin film of ${\text{BaTi}}_{0.98}{\text{Co}}_{0.02}{\text{O}}_{3}$ (CBTO) with detailed structural and magnetic analyses. The films are single phase with an inhomogeneous distribution of ${\text{Co}}^{2+}$ dopants i…
Abstract We report the preparation, through palladium‐catalyzed transformations, of the indolylfulgimide linker conjugate 1 , containing an adamantane core and nitrile anchoring groups. The ethynylene‐linker 12 for the final Sonogashira coupling was prepared through palladium‐mediated cyanation of an iodo‐substituted…
