A two-dimensional coordination network, (2)(∞)[Fe(III) (OH)(e,a-cis-1,4-chdc)] (1,4-chdc: cyclohexane-1,4-dicarboxylate), featuring one-dimensional iron(III)-hydroxy chains that are transversely bridged by 1,4-chdc in its pure e,a-cis conformation have been isolated. The magnetic study shows a typical spin-5/2 Heisenb…
A numerical simulation of the radiological consequences of the RB reactor reactivity excursion accident, which occurred on October 15, 1958, and an estimation of the total doses received by the operators were run by the MCNP5 computer code. The simulation was carried out under the same assumptions as those used in the…
Soy protein has been considered as a kind of natural polymer and an ecological material that was widely used in many fields such as food industry. In this paper, the soy protein isolate (SPI) was modified by glutaric dialdehyde and characterized by IR spectra, scanning electron microscopy (SEM) and X-ray diffraction (…
Patterned cathodes of La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF-6428) were deposited on 8 mol% yttria-doped stabilized zirconia (YSZ) substrates with a Gd-doped ceria barrier layer by rf-magnetron sputter deposition. Patterns were generated with triple phase boundary (TPB) lengths ranging from 50 to 1200 cm −1 . Electro…
The effects of high gamma-irradiation doses (50-300 kGy) on natural quartz crystals have been investigated by ESR technique. The ESR spectrum carried out at low temperature (120 K) displayed lines group of Al center. The higher amount of gamma doses affected ESR spectra by increasing of intensity, especially the incre…
Growth of aligned nanorod arrays on substrates are important for their device applications, but only dispersive Cu 2 O nanorods were prepared by wet processes for previous researches. In the work, single-crystalline Cu 2 O nanorod arrays were directly grown on substrates for the first time via a NaOH-assisted dry proc…
A facile and one-step colorimetric detection of hydrazine has been developed for the first time during the formation of size-controlled amidosulfonic acid capped gold nanoparticles (AA-AuNPs). Hydrazine served not only as a target analyte but also a reductant to react with chloroauric acid (HAuCl4). In order to obtain…
Mie scattering centers comprised of high-refractive-index Cu 2 O are prepared using a rapid one-step electrodeposition procedure. The deposition of cubic nanoparticles is facilitated by a high-pH precursor solution, which allows for low Cu 2 O nucleation density and large grain size. The scattering resonant frequency…
FexOy hollow nanospheres were synthesized inside cage type mesoporous silica LP-FDU-12 through nanocasting. The sample was reduced to Fe3O4 and then further oxidized to γ-Fe2O3 with little changes in morphology and size. The Verwey transition is observed in the Fe3O4 hollow nanosphere system for the first time with ma…
Nanoscopic NaCl was prepared by elimination from sodium malonate and phenacyl chloride with a particle diameter of 100 nm. The NaCl crystals were added to either poly(D,L)lactide or polysulfone (dissolved in dichloromethane) as water-soluble porogens. The dispersion was applied to silicon wafers by dip-coating. After…
We present three different in-situ post anodization electrochemical techniques to thin down the barrier oxide layers. These techniques include exponential voltage decay, exponential voltage decay with steps and exponential current decay. Faster rate of voltage drops in case of exponential voltage decay results in pore…
The effects of ultra high molecular weight Polyacrylonitrile (UHMW-PAN) on the rheological behavior of PAN/DMSO solution have been investigated using a cone-plate rheometer in this work. The rheological behavior was characterized by steady shear and oscillation test It is observed from the measurements that, the rheol…
Individually dispersed single-walled carbon nanotubes (SWCNTs) were isolated and stabilized from electrostatically tethered nanoplatelets in aqueous solution, following nanoplatelet-assisted exfoliation. SWCNT isolation was achieved by precipitating nanoplatelets with cations and by concurrent usage of appropriate sur…
Current-voltage characteristics of symmetric ferroelectric tunnel junction were studied in an ultrathin ferroelectric barrier with the consideration of the thickness and strain dependent converse-piezoelectric effect. With proper boundary conditions, large piezoelectric strain can be achieved in the ferroelectric barr…
As a new building materials, mechanical properties﹑physical properties and chemical properties of basalt fibers are studied in the paper. Compared with other building materials, the basalt fibers have better tensile strength than the E-glass fibers, greater failure strain than the carbon fibers as well as good resista…
In this paper, the authors report in situ surface enhanced Raman spectroscopy (SERS) experiments carried out during the electrochemical deposition of Y2O3/Au from chloride salts dissolved in hydroalcoholic solutions containing chitosan as a binder. This composite was recently proposed by the authors as an electronical…
The antharquinone-based chromophore of 11-hydroxyaklavinone is present in the structure of an anticancer agent, daunomycin. On the other hand, aklavinone is the parent aglycone of certain anthracycline antibiotics that possess anti-cancer activity too. The structures of aklavinone and its 11-hydroxy derivative have ma…
The prevalence of chronic kidney disease and peripheral arterial disease is increasing. Thus, it is increasingly problematic to image these patients as the number of patients needing a vascular examination is increasing accordingly. In high-risk patients with impaired kidney function, intravascular administration of i…
A Johnson-Cook type damage law, with pressure and temperature coefficients from published literature, is applied to simulations of carbon steel chip formation in general engineering built up edge (bue) conditions. Secondary shear zone damage and strain-rate contours are predicted with incipient bue appearance. The mod…
Bacterial cellulose (BC) was altered by means of 0.5-2.5% w/v diacetylglycerol in acetone-water through impregnation process provided DGBC composites. Results from the scanning electron microscope images, revealed that diacetylglycerol filled the pores of BC, leads to the significant enhanced in hydrophilicity and cau…
