The purpose of this research is to investigate the corrosion rate of low carbon steel in saline environment. The influence of variety of conditions that represent the actual conditions in practice such as the flow velocity and solution composition, particularly Na+, Cl - and SO 4 -2 , content were performed. Weight lo…
We, the Editors and Publisher of the journal Artificial Cells, Nanomedicine, and Biotechnology, have retracted the following article:Sahar Jahangiri & Abolfazl Akbarzadeh (2016) Preparation and in vitro evaluation of Methotrexate-loaded magnetic nanoparticles modified with biocompatible copolymers. Artificial Cells, N…
A series of oligomers based on the mixture of thioetherdiphthalic anhydride isomers and 4,4′-oxydianiline with 4-phenylethynylphthalic anhydride as reactive endcapping reagent were prepared. The calculated molecular weights were in the range of 1150–5070 g mol −1 with different degrees of polymerization ( n = 1, 3, 5,…
SUMMARY In order to study the acoustic noise generated by transformer cores, the impacts of the types of core joint and the number of laminations per layer on noise levels were investigated. In addition, localized magnetostrictions on transformer cores were measured with strain gages, and the differences caused by the…
We report polycrystalline BaTiO3 with cooperative magnetization behavior associated with the scarce presence of about 113 atomic ppm of Fe ions, clearly displaying magnetoelectric coupling with significant changes in magnetization (up to ΔM/M ≈ 32%) at the ferroelectric transitions. We find that Fe ions are segregated…
The aim of this work is to examine the properties of CNTs formed on Fe-Co and Ni-Co bimetallic catalysts supported on different phases of TiO2 (anatase and rutile) by wet impregnation method. The CNTs are grown from decomposition of acetylene via Thermal CVD at 700°C using the prepared catalysts. The nanomaterials wer…
Picture frame test on woven fabrics is not completely controlled and misalignment is one of the tremendous factors. The aim of this study was to investigate the effect of misalignment on the shear response of plain woven fabric in picture frame test. Misaligned and aligned specimens of plain woven fabric were tested,…
Relying on an exact time evolution scheme, we identify a novel transient energy transfer phenomenon in an exactly-solvable quantum microscopic model consisting of a three-level system coupled to two non-Markovian zero-temperature bosonic baths through two separable quantum channels. The dynamics of this model can be s…
Cu/Cu2O composite structures have been discovered to show sizable ferromagnetism (FM) with the potential applications in spintronic devices. To date, there is no consensus on the FM origin in Cu/Cu2O systems. Here, first principles calculations are performed on the interface structure to explore the microscopic mechan…
Heterojunctions of p-type cubic boron nitride (cBN) and n-type silicon with sp2-bonded BN (sp2BN) interlayers are fabricated under low-energy ion impact by plasma-enhanced chemical vapor deposition, and their rectification properties are studied at temperatures up to 573 K. The rectification ratio is increased up to t…
Ring-opening polymerization (ROP) of monofunctional neopentylglycol carbonate (NPGC) with or without bifunctional di(trimethylolpropane) carbonate (DTMPC), which are derived from available corresponding alcohols, affords linear polycarbonates or covalently-linked polycarbonate networks, respectively. A series of avail…
A novel type of nanotwinned austenitic stainless steel consisting of the nanotwinned grains embedded in coarsened nano‐sized grains and recrystallized matrix was synthesized. Potentiodynamic polarization measurements indicate that the nanotwinned samples exhibit a higher passive ability in the acidic solution and a co…
Phosphorus-containing epoxy resin is an intrinsic flame-retardant thermoset polymer with P element chemically grafted on the backbone of the macromolecular chains. In this article, two inorganic metal hydroxide flame retardants, aluminum hydroxide and magnesium hydroxide possessing similar flame retardance mechanism,…
Here, we report a determination of monoclinic nanodomains in PMN-xPT with x = 31%PT by using scanning convergent beam electron diffraction (SCBED). We show the presence of 60 ± α degree nanodomains with Cm-like symmetry as well as significant variations (α) in local polarization directions across lengths of ∼10 nm. Th…
We study two-dimensional transport of quasiparticles in bilayer graphene through a modified P\"oschl-Teller potential, a potential with hyperbolic profile. Both scattering by well and tunneling through a barrier are investigated. At normal incidence the oscillating and evanescent wave states are completely decoupled,…
Fibrous sepiolite(Sep)/fluororubber (FKM) composite was prepared by co‐mixing and heat molding. Fibrous aggregation of acid sepiolite(aSep) was prepared by acid exfoliation of mineral sepiolite, and then organic sepiolite(oSep) was prepared by coupling agent modification of aSep. The crystal structure, chemical compos…
In this work untreated and alkali treated nonwoven coconut fiber mats/epoxy resin composites were manufactured using the resin transfer molding process. The alkaline solution removes some impurities present on fibers superficial layers and the effect regarding fiber/matrix adhesion were investigated by thermogravimetr…
The objective of this study was to evaluate mechanical (tensile modulus and strength and flexural modulus and strength) and physical (water absorption and thickness swelling) properties of wood–plastic composites made from industrial wood particles used for manufacturing three-layer particleboards and highdensity poly…
Abstract A catalyst consisting of copper nanoparticles (15–20 nm in size) supported on ordered mesoporous cobalt monoxide was synthesized by the one‐step reduction of ethanol from nanocast copper cobalt spinel oxides. The small‐angle X‐ray scattering patterns showed that the ordered mesostructure was maintained after…
In this Letter, we study numerically diffraction gratings for surface plasmon polaritons. Investigated plasmonic gratings consist of a periodic set of dielectric ridges located on the metal surface. The grating period is comparable with the wavelength of the incident wave. The simulation results obtained within the ri…
