Abstract Anodically etched two‐dimensional (2‐D) arrays of highly ordered sub‐200 nm in diameter vertical cylindrical pores were fabricated on p‐type Si wafers, with a resistivity of 6–8 Ω cm, by non‐lithographic pre‐patterning of the silicon substrate through a self‐assembled porous anodic alumina (PAA) thin film, di…
Abstract A new Eu‐containing copolymer was successfully fabricated through two steps. First, the Eu‐containing monomer was synthesized from 4‐Vinylbenzoic acid and europium ion (Eu 3+ ) complex, which rare‐earth ions connect with the ligand by covalent bands. Next, the copolymer was obtained by free‐radical copolymeri…
Abstract In this paper we prove the existence and uniqueness of a global in time, regular solution to the Cahn–Hilliard system coupled with viscoelasticity. The system arises as a model, regularized by a viscous damping, of phase separation process in a binary deformable alloy quenched below a critical temperature. Th…
Abstract A novel copper‐poly(vinyl alcohol) (PVA)/silica complex was prepared and its chemical structure, thermal, and mechanical properties were studied. The results showed that the crystallinity of PVA first increased and then decreased by the addition of copper chloride, whereas, the thermal decomposition temperatu…
The effects of ethanol on the thickness and ionization of adsorbed polymer layer on pigment were investigated. The results showed that the thickness of adsorbed polymer layer decreased with the increase of the ethanol concentration, and then the pigment particles aggregated when the concentration of ethanol is higher…
The present investigation reports a new processing technique that can reduce the sintering temperature of Sr‐ and Mg‐doped lanthanum gallate (LSGM), a good candidate material for the electrolyte of the solid oxide fuel cell (SOFC). When LSGM was sintered at 1623 K for 5 h in N 2 or O 2 , the samples were densified ove…
Erbium oxide dielectrics with a thickness of ∼6 nm were fabricated in situ on In0.53Ga0.47As channels. Leakage current and capacitance densities were characterized as a function of applied voltage using metal-oxide-semiconductor capacitors with two different top electrode materials, Pt and Al. Leakage current densitie…
( 1 − x ) Pb ( Mg 1 / 3 Nb 2 / 3 ) O 3 - x PbTiO 3 (PMNT) (with x=0.1) thin films were prepared on Pt-coated silicon substrates by radio-frequency magnetron sputtering and postdeposition annealing method. A well-crystallized pyrochlore phase structure, which started to nucleate and grow at 450–500 °C, was formed in th…
Abstract The cyclic fatigue crack behavior of polyvinyl chloride (PVC), with (PVC‐M) and without (PVC‐U) chlorinated polyethylene (CPE) impact modifier, was studied. The effect of impact modifier upon fatigue crack growth rate and threshold was evaluated at frequencies of 1, 7, and 20 Hz. It was shown that the additio…
Abstract We have analyzed Cu(InGa)Se 2 thin films, fabricated by standard deposition technique for solar cells, by near‐field scanning optical microscopy (NSOM) which allows for simultaneous detection of photoluminescence (PL) and AFM‐like topography. In comparison with our former confocal microscopy studies this appr…
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…
