CuCo co-doped ZnO nanorods have been synthesized via a soft chemistry route without using any surfactant, seed and catalyst. Structural analyses reveal that the samples of nominal compositions Cu0.01Co0.02Zn0.97O and Cu0.02Co0.01Zn0.97O have single hexagonal wurtzite structure without forming any extra secondary phase…
C / β -SiC / Si hybrid microtubes have been fabricated by releasing prestressed C/Si bilayer structures and treating with a postannealing process. Detailed characterization reveals the synthesis of β-SiC via a solid phase reaction at the C/Si interface. Remarkably, the production of β-SiC is promoted in the tube wall…
Abstract Bibliometric methods, in particular citation analysis, are used to evaluate the International Journal of Materials Research (IJMR) and its two predecessor journals Zeitschrift für Metallkunde (ZfM) and Internationale Zeitschrift für Metallographie (IZfM). Firstly, the coverage of the journals by the various l…
Ultrafine-grained materials, having grain sizes in the submicrometer or nanometer range, may be readily produced by processing bulk solids through the application of severe plastic deformation (SPD) and this leads to the possibility of revealing different flow mechanisms when these materials are tested at elevated tem…
Structural characteristics and thermal behaviour of the conventionally solidified Al–Cu–Fe alloys with nominal compositions of Al70Cu20Fe10, Al65Cu20Fe15 and Al63Cu25Fe12 were investigated by X-ray diffraction, scanning electron microscopy, and differential thermal analysis techniques. Results show that a single quasi…
The (SYCM) oxide with a cubic perovskite structure was examined as a promising cathode material for intermediate temperature solid oxide fuel cells (IT-SOFCs). The electrical conductivity, thermal expansion coefficient (TEC), and reactivity with gadolinia-doped ceria (GDC) or yttria-stabilized zirconia (YSZ) were stud…
The dehydration behavior of the paraelectric phase of was investigated by thermogravimetric and X-ray diffraction analyses, and then the phase diagrams of system were established. The relationship between the onset temperature of dehydration and the partial pressure of water is below . The thermodynamically stable pha…

The interaction of octaethyl-and octaphenyltetrapyrazinoporphyrazines with dimethylsulfoxide was investigated. The structure of proton transfer complexes has been defined. The complex formation of magnesium octaethyltetrapyrazinoporphyrazine was studied in pyridine. Kinetic parameters of the reaction are defined and t…
Three zirconium alloys (Zry-4, Zry-2, and NDA) were corrosion tested at 633 K in pure water and in mixed gas of Ar and oxygen. In both environments, their corrosion rate showed cyclic changes. The time and the weight gain at the transition point changed with their corrosion resistance. In the pure water corrosion test…

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E> 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. Th…
The inhibiting action of sinapinic and gentisic acid on Al-0.8Mg alloy in 0.5 mol dm-3 NaCl solution was studied using potentiodynamic polarization method, linear polarization method, and electrochemical impedance spectroscopy measurements. Investigations were performed on a rotating disc electrode in a quiescent solu…
New methacrylic monomers containing pendant azobenzene structures have been prepared by reacting azobenzene assemblies possessing phenolic functions with methacryloyl chloride. The most favorable synthetic routes are described together with the yields obtained. The new monomers have been purified and completely charac…
The magnetic resonance of various split ring resonators (SRRs) is numerically investigated to analyze the dependence of the resonance frequency on their parameter designs. The behavior of the magnetic resonance frequency in the configuration of the 2-cut singlering SRR (2C-SRR) shows a larger shift in relation to the…
This paper presents how metamaterials can be used to enhance antenna bandwidth. To this purpose, a particular metamaterial cell is introduced for which its design parameters are detailed. This cell is then used to enhance the performances of a microstrip antenna which can be found in communication systems.
The electrochemical injection of holes into the valence band of mercaptopropionic acid stabilised CdTe quantum dots in aqueous solution was investigated employing a glassy carbon rotating disc electrode. Analysis of the first exciton peak and the electrochemical responses as a function of the particle size was perform…
ZnO thin films were prepared on a quartz substrate by sol-gel method and a UV photodetector was constructed on the ZnO thin films, with a circular spiral structure in contact with 30 nm IrO2 electrodes. The ZnO thin films were crystallized at various crystallized temperature (600∼700°C) for 1 hour in pure oxygen atmos…
The aqueous extract of Cassia auriculata leaves (Awali), Erythrina variegate leaves (Pangora) and Dioscorea bulbifera bulbs(Kand) were investigated for their anthelmintic potential against earthworms (Eicinia faeteda), tapeworms(Raillietina spiralis) and roundworms(Ascardia galli). Various concentrations (10-50 mg/ml)…
