The corrosion inhibition efficiency of a potential polynuclear Schiff base, (s)-2-(anthracene-9 (10H)-ylidene amino)-5-guanidinopentanoic acid (A9Y5GPA), on carbon steel (CS) in 1 M hydrochloric acid solution has been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS), and potent…
X-ray microanalysis conducted using the scanning electron microscope is a technique that allows the determination of chemical elements in bulk or semi-thick specimens. The lowest concentration of an element that can be detected is in the order of a few mmol/kg or a few hundred parts per million, and the smallest amoun…
Electric field activated nonlinear transport is investigated in polypyrrole thin film in both in-plane and out-of-plane geometries down to 5 K and strong anisotropy is observed. A morphological model is suggested to explain the anisotropy through inter-chain and intra-chain transport. The deviation from the variable r…
We evaluated electronic structures and magnetic moments in Co3FeN epitaxial films on SrTiO3(001). The experimentally obtained hard x-ray photoemission spectra of the Co3FeN film have a good agreement with those calculated. Site averaged spin magnetic moments deduced by x-ray magnetic circular dichroism were 1.52 μB pe…
Rhodium supported on lanthanoid (La, Ce, Pr, or Nd)-containing ZrO2 was investigated as a three-way catalyst following an aging treatment (oxidation at 1273 K) that simulates 80 000 km of mileage in real vehicles. The properties of rhodium were assessed by transmission electron microscopy, CO chemisorption, and temper…
Abstract We have demonstrated that oligo(phenylisoxazolyl)benzenes 3–6 formed polymeric assemblies. The intermolecular associations were discussed using thermodynamic parameters. The formation of the polymeric assemblies were confirmed by DOSY and AFM measurements. The large polymeric structures were observed both in…
In this work, a hybrid‐polymer nanocomposite film, based on polyvinyl butyral/amino‐silane functionalized nano alumina, was fabricated by melt processing. The calcium degradation measurements suggest the functionalized nanocomposite films exhibit higher resistance towards moisture penetration as compared to the neat a…
N-type doping of graphene with long-term chemical stability in air represents a significant challenge for practical application of graphene electronics. This paper reports a reversible doping method to achieve highly stable n-type graphene nanomeshes, in which the SU-8 photoresist simultaneously serves as an effective…
The strong softening of the tetragonal shear elastic constant (C′) is the main reason for the second magnetostriction peak observed in Fe100–xGax alloys. Here, we study the coupling between chemical order and magnetism with the aim to understand the origin of the elastic softening. We demonstrate that C′ strongly depe…
Two types of multi-walled carbon nanotubes (MWCNTs) were used to modify unsaturated polyester (UP) through the formation of composites. The pristine MWCNTs, polyester, and the obtained carbon nanotubess/polyester composites were characterized chemically and physically using scanning electron microscopy, surface area a…
Wollastonite‐filled α ‐isotactic polypropylene (iPP) and β ‐iPP were prepared through introduction of wollastonite (W) and wollastonite with β ‐nucleating surface (W x ) in iPP matrix. The α ‐ and β ‐nucleating ability of wollastonite, crystalline morphology, and mechanical properties of injected iPP filled by wollast…
Graphene Oxide (GO) was prepared from natural graphite and treated with different types and various amounts of cationic surfactants to form the intercalation nanocomposites. The resulting specimens were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrum (FT-IR), X-ray diffraction…
A novel method of Pickering emulsion polymerization stabilized by graphene oxide (GO) and the role of adding salt (NaCl) were first described here. The ability of GO lower the interfacial tension and the effect of adding salt (NaCl) on particle adsorption at the oil–water interface were studied. It was found that GO n…
(18)O/(16)O exchange annealing and subsequent Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) analysis is used to investigate oxygen transport in dense, nanocrystalline (average grain size d ≈ 300 nm) ceramics of nominally un-doped BaTiO3. Isotope penetration profiles are obtained as a function of temperatur…
We show that a rectangular metallic waveguide loaded with metamaterial elements consisting of electric-field-coupled (ELC) resonators placed at the sidewalls can operate well below the cutoff frequency of the respective unloaded waveguide. For the example considered of a waveguide with square cross-section and origina…
Globally, graphene magnetism has captivated the attention of researchers in recent years. To obtain magnetic ordering, irregularities in the carbon network, like defects, adatoms, etc., are essential. Herein, we report on spin transport and magnetic correlations in graphene-like nanocarbon sheets (GNCs) that were dope…
To realize transparent conducting oxide (TCO) films with the combined desirable characteristics of both SnO2 and ZnO, SnO2:F/ZnO:F bilayered thin films were fabricated with varying thickness of over-layer using a simplified spray pyrolysis technique. The electrical studies revealed that the bilayered films exhibit les…
From high-precision Brillouin spectroscopy measurements, six elastic constants (C11, C33, C44, C66, C12, and C14) of a flux-grown GeO2 single crystal with the α-quartz-like structure are obtained in the 298-1273 K temperature range. High-temperature powder X-ray diffraction data is collected to determine the temperatu…
Arrays of twisted carbon nanotubes and nanotube ropes are equivalent to a torsional spring capable of storing energy. The advantage of carbon nanotubes over a twisted rubber band, which is used to store energy in popular toys, is their unprecedented toughness. Using ab initio and parametrized density functional calcul…
Based on polymer perfusion behaviour inside carbon nanotube (CNT) networks, the thermal transport performances of the CNT networks with various extents of polymer intercalation are studied by dividing them into two parts: thermal transport at the tube contact interfaces of CNT junctions and along the tube axis. The th…
