Nowadays super-duplex stainless is an important material for the Oil and Gas industries, especially for off-shore production. In deep water exploitation the reliability of production system is very important. Corrosion resistance for pitting of the high alloyed duplex stainless steels with high Mo and N content has to…
In the past decade many structures of nucleic acids have been determined, which have contributed to our understanding of their biological functions. However, crystals containing nucleic acids often diffract X-rays poorly. This makes electron-density interpretation difficult and requires a great deal of expertise in cr…
PURPOSE: To compare enhancement of the liver and pancreas quantitatively on late hepatic arterial phase images among various gadolinium-based contrast agents (GBCAs) at 1.5 Tesla (T) MRI. MATERIALS AND METHODS: Patients underwent consecutive MR studies with the following GBCAs: gadopentetate dimeglumine (0.1 mmol/kg)…

In a recent paper by Ngai and Capaccioli ["Unified explanation of the anomalous dynamic properties of highly asymmetric polymer blends," J. Chem. Phys. 138, 054903 (2013)] the authors claimed that the so-called coupling model (CM) provides a unified explanation of all dynamical anomalies that have been reported for dy…
Two experiments were conducted to evaluate the effect of chitosan as a biological sanitizer on chicken skin during storage. For experiment 1 (two trials) five skin samples of equal size were dipped into a solution containing 106 cfu/mL of Salmonella Typhimurium (ST) for 30s. Skin samples were then removed and dipped i…
Ag 9 FeS 4.1 Te 1.9 was prepared by solid state synthesis from stoichiometric amounts of the elements at 873 K. The compound forms gray crystals which are stable against air and moisture. The crystal structure was determined by X-ray diffraction from selected single crystals. Ag 9 FeS 4.1 Te 1.9 crystallizes in the sp…
Abstract Concentrated nitric acid‐treated multiwalled carbon nanotubes (MWCNTs) are functionalized with active poly(4‐chloromethyl styrene) (PCMS) through the esterification reaction of the carboxyl groups of the former and the p‐benzyl chloride groups of the latter in the presence of a phase‐transfer catalyst. Charac…
The fusion of graphene with silicon may provide an effective solution to the problem of scale in electronic devices. This approach will allow the excellent electronic properties of graphene to be combined with known Si device technologies. We review the epitaxial growth of graphene on Si substrates (GOS) for fabricati…
A novel hexagonal tungsten oxide (HTO)-like layered framework containing a main-group cation, In(3+), and a lone-pair cation, Te(4+), is reported. Na(1.4)InTe(3.6)O(9.4) exhibits a layered structure consisting of InO6, TeO3, and TeO4 polyhedra. The synthesis, crystal structure determination, characterization, and reac…
A series of arsenotungstates formulated as (H 2 en) 3.5 [HAs 2 W 8 O 31 ]·6H 2 O ( 1 ), Na 0.5 (H 2 en) 6.5 {Ni 3 (en)[B-α-AsW 9 O 34 ][B-β-AsW 8 O 31 ]}Cl 1.5 ·9H 2 O ( 2 ), and [H 2 en] 4 {[Ni 4 (Hen) 2 ][B-α-AsW 9 O 34 ] 2 }·5H 2 O ( 3 ) have been sequentially synthesized by controlling the reaction process. First,…
Abstract New mixed‐valence Cu I –Cu II 1D coordination polymers of the structure [Cu I 2 Cu II X 2 (Pip‐dtc) 2 (CH 3 CN) 2 ] n [Pip‐dtc = piperidine‐1‐carbodithioate; X = Br ( 1a ), I ( 1b )] containing a dithiocarbamate derivative have been synthesized and structurally characterized by X‐ray diffraction. The 1D infin…
The structure of kaolinite at the atomic level, including the effect of stacking faults, is investigated using inelastic neutron scattering (INS) spectroscopy and density functional theory (DFT) calculations. The vibrational dynamics of the standard crystal structure of kaolinite, calculated using DFT (VASP) with norm…
First-principles calculations based on the density functional theory (DFT) within the generalized gradient approximation (GGA) have been used to study Sc -doped TiO 2 , rutile and anatase, crystals. Local defect microstructure, electronic and electrical properties have been obtained and discussed in the present work.…
Background: Despite the wide range of applications, there is a serious lack of information on the impact of the nanoparticles on human health and the environment. The present study was done to determine the range of dangerous concentrations of iron oxide nanoparticle and their effects on mouse embryonic stem cells. Me…
This work aims at studying the effect of the milling conditions on the microstructure and mechanical properties of a ZrB₂-5 vol% Si₃N₄ matrix reinforced with chopped Hi-Nicalon SiC fibers. Several composites were obtained using different milling conditions in terms of time, speed and type of milling media. The composi…
Abstract The crystal structure of syndiotactic polystyrene (sPS) co‐crystals of δ‐class is discussed with the aim of identifying molecular descriptors that allow predicting the lattice distortions induced by the inclusion of guest molecules inside the cavities of the nanoporous δ‐form. Based on the consideration that…
In this work, we studied enzyme-catalyzed oxidation of single-walled carbon nanotubes (SWCNTs) produced by the high-pressure carbon monoxide (HiPco) method. While oxidation via strong acids introduced defect sites on SWCNTs and suppressed their near-infrared (NIR) fluorescence, our results indicated that the fluoresce…
A field-effect transistor has been fabricated utilizing an epitaxial film of unstrained zinc-substituted magnetite (Fe 3 O 4 ) as the active channel. A thin film of Fe 2.5 Zn 0.5 O 4 was grown on a lattice-matched MgO(001) substrate by pulsed-laser deposition and covered by a parylene gate insulator to dope charge car…
Abstract Syndiotactic polystyrene (sPS) forms cocrystals with a variety of chemical compounds. The guest molecules can be easily replaced with other kinds of molecules under certain conditions. The guest‐exchange process, on exposure to liquid triethylene glycol dimethyl ether (TEGDME), is followed by time‐resolved si…
