Interlayer exchange coupling (IEC) behavior in epitaxial Co2MnSi (20 nm)/Cr/Fe (7 nm) trilayers has been investigated against Cr spacer thickness (tCr= 0.3-6.3 nm). High-quality trilayer samples have grown on a Cr (5 nm)/Au (30 nm)/Cr (15 nm) buffer layer on a MgO substrate by ultrahigh vacuum (UHV) compatible dc sput…
Here we present a new method for improving adhesion between natural rubber (NR) and polyester fabric. This is done by in situ grafting of maleic anhydride (MA) onto NR in a two-roll mill. The grafting procedure was followed by infrared spectroscopy (FT-IR). The effect of ultraviolet/ozone (UV/O3) radiation on the stab…
This paper reports that the large-scale single crystalline boron carbide nanobelts have been fabricated through a simple carbothermal reduction method with B/B 2 O 3 /C/Fe powder as precursors at 1100°C. Transmission electron microscopy and selected area electron diffraction characterizations show that the boron carbi…
Mixed oxide fuel assemblies (MFA-1 and MFA-2 assemblies) were irradiated in the fast flux test facility to evaluate the irradiation performance of fast reactor core fuels at high burnups and high fast neutron fluences. The MFA-1 and MFA-2 assemblies achieved respective peak pellet burnups of 147 and 162GWd/t, and resi…
Pressureless‐sintered BaTiO 3 ceramics containing ferroelectric domains are subjected to Vickers microindentation at room temperature. Domain switching along indentation cracks is investigated using electron backscatter diffraction (EBSD) in a scanning electron microscope. Crystallographic orientation relationships be…
This paper studies the electronic structure and native defects in transparent conducting oxides CuScO 2 and CuYO 2 using the first-principle calculations. Some typical native copper-related and oxygen-related defects, such as vacancy, interstitials, and antisites in their relevant charge state are considered. The resu…
Carbon powder has been functionalized with nitroazobenzene groups by the reduction of 3-methoxy-6-methyl-4- [(2-nitro-4-methylphenyl) azo] benzene diazonium zinc chloride double salt (“ Fast Corinth V zinc chloride double salt”) in the presence of hypophosphorous acid as a chemical reducing agent. This provides an eas…
YAG:Ce nanosized spherical precursors were synthesized by coprecipitation using ammonium hydrogen carbonate as precipitant. Composition, phase transition, morphologies, and luminescence properties of the powders during calcination were studied. The precursors directly convert to pure YAG structure at about 900°C. The…
Of the four reported complexes (Ph2Bq-x2), where x2��5,7-dibromo (1); 5,7-diphenyl (2); 5,7-bis(biphenyl-4-yl); 5,7-bis(9,9-dihexylfluoren); q��8-quinolinelate, the replace- ment of 5,7-bis(biphenyl-4-yl) and 5,7-bis(9,9-dihexylfluoren) by di(p-nitrostyryl) (3) and distyoyl (4), respectively, can also cause significan…
The effect of cationic template on the adsorption of copper-phthalocyanine-3,4′,4′′,4′′′-tetrasulfonic acid tetrasodium salt [Cu(tsPc)−4·4Na+] in MCM-41 and MCM-48 mesoporous materials was investigated, using cetyltrimethylammonium bromide (CTAB) as the cationic template and tetraethyl-orthosilicate as the silica sour…
The influence of deformation conditions on the formability of magnesium alloy was systematically investigated using the experimental method and finite element analysis. The research activity aimed to gain further insight into the formability of magnesium alloy AZ31 (aluminium 3 wt per cent, zinc 1 wt per cent) and to…
Triple molybdates of the compositions Rb 5 LnHf(MoO 4 ) 6 (5:1:2) and Rb 2 LnHf 2 (MoO 4 ) 6.5 (2:1:4), Ln = Ce-Lu, were prepared by solid-phase reactions. The temperature dependence of the electrical conductivity of the compounds Rb 5 LnHf(MoO 4 ) 6 (5:1:2) at 200–500°C was studied.
We present preliminary studies of magnetic and transport properties of Ge 1-x-y Sn x Mn y Te mixed crystals with 0.091 x 0.105 and 0.012 y 0.115. Qualitative analysis of our experimental results showed the appearance of a spin-glass phase at T < 50 K. The transport characterization (resistivity and Hall effect measure…
We have recently been able to grow single-walled carbon nanotubes by purely thermal chemical vapour deposition (CVD) at temperatures as low as 400 degrees C. This has been achieved by separating the catalyst pre-treatment step from the growth step. In the pre-treatment step, a thin film catalyst is re-arranged into a…
Corona discharge is being detected by UV imaging detection technology at home and abroad in recent years. This technology is used in the corona tests of bundled conductors in this paper. In order to further research the corona characteristic, optimize geometry parameters and diameter of sub-conductor, and increase cor…
This paper presents a novel three-phase laminated-core variable inductor made for the purpose of voltage stabilization in electric power systems. The proposed variable inductor has three-phase secondary ac windings together in one laminated-core to reduce the size and weight in comparison with the other single-phase o…
The magnetic properties of La0.7Ca0.3MnO3(LCMO) manganite thin films were studied with magnetometry and ferromagnetic resonance as a function of film thickness. They maintain the colossal magnetoresistance behavior with a pronounced metal-insulator transition around 150-200 K, except for the very thinnest films studie…
A thin coating with an extended reaction (see Acoust. Phys. 53 , 535 (2007)) is used to reduce the reflection and scattering of waves from an infinite cylinder. The coating is shown to be more efficient compared to conventional coatings.
Abstract Cobalt nanoparticles loaded on an activated carbon catalytically excavated the activated carbon when it was heat-treated in a 1 atm stream of a mixture of hydrogen and argon gases at high temperature. The BET surface area of the activated carbon decreased from 2210 to 1750 m2 g−1, and the mesopore volume incr…
Optical imaging using unspecific contrast agents as well as targeted and disease-specific agents play a vital role in preclinical research. Moreover, optical imaging is on the verge of establishing itself as a clinically relevant imaging modality. Also in-vitro diagnostical procedures rely to a large degree on optical…
