Nanotechnology based on the use of submicronic particles of inorganic and/or organic origin has the potential to revolutionalize the clinical management of cancer; the possibility of real time monitoring of disease progression and effects of therapy is now real. Especially, iron oxide super paramagnetic nanoparticles…
The crystal structure of kudriavite, (Cd,Pb)Bi 2 S 4 , a new mineral species, was solved from single-crystal X-ray-diffraction data and refined to R = 4.9% (4.3% for a model with split mixed-cation sites). Lattice parameters are a 13.095(1), b 4.0032(3), c 14.711(1) A, β 115.59(1)°, V 695.6(1) A 3 . The structure is e…
New chiral pincer ligands having CH=N moieties were synthesized by condensation of 1 H -pyrrole-2,5-dicarbaldehyde with l -methionine and l -histidine methyl esters. Their reduction under mild conditions (NaBH 4 , −30°C) gave the corresponding amine ligands in high yields. An improved procedure for the preparation of…
We have performed a detailed resonant x-ray scattering (RXS) study at the $\mathrm{Mn}\phantom{\rule{0.3em}{0ex}}K$ edge of $\mathrm{La}\mathrm{Mn}{\mathrm{O}}_{3}$ by measuring the $(h,0,0)$, $(0,k,0)$ and $(0,0,l)$ forbidden reflections $(h,k,l=3,5)$ between 10 and $300\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ in the $…
Article Crystal structures of iron distannide, FeSn2, and cobalt distannide, CoSn2 was published on June 1, 2007 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 222, issue 2).
The silica-supported nickel phosphide, Ni2P/SiO2, was prepared by the temperature-programmed reduction method, and the influence of reduction conditions (H2 flow rate, reduction temperature, and time) on the textural properties of the catalyst was investigated. There was no remarkable difference in BET specific surfac…
Transport, magnetic, and structural properties of Sm1−xAxMnO3, where A is Ca and Sr, have been investigated systematically over the range of doping 0⩽x⩽0.52. For x<0.30, both systems are ferromagnetic (FM) insulator, and the resistivity (ρ) can be described well by polaron hopping model. Above x=0.30, Sr-doped…
Due primarily to cell sourcing issues, many in the field of tissue engineering have opted to create scaffolds that promote in situ regeneration, using the body as both the bioreactor and the cell source for the remodeling of scaffolds, resulting in the formation of native tissue. This practice raises many concerns, wi…
The kinetics of molybdenite oxidation was studied by non-isothermal TGA-DTA with heating rate 5 oC.min -1 .The model-fitting kinetic approach applied to TGA data .The Coats-Redfern method used for model fitting. The popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. The…
The emergency power supply system, which is composed of a SMES system cooled by liquid hydrogen and a fuel cell (FC), is proposed as a backup for supplying electricity to hospitals, high-rise office buildings, and intelligent equipment. The capacity of the system is 2 MW for 10 hours. At a power failure, the SMES imme…
Two ZnO nanostructures with multisegment structure have been synthesized by a chemical vapor deposition (CVD) method on a silicon substrate. The top size of the nanostructures can reduce to 10−30 nm, which is beneficial to field emission applications. Scanning and transmission electron microscope methods are applied t…
In this study, BiFeO 3 (BFO) epitaxial film was deposited on SrRuO 3 (100)/SrTiO 3 (100) substrates by pulsed laser deposition (PLD). Phase-pure BFO thin film was obtained by introducing a mask between the target and the substrate in the deposition chamber. The use of the mask brought about an improvement in the morph…
Semi-cycloaliphatic (semi-alicyclic) polybenzoxazoles (PBOs) were investigated as candidates for flexible plastic substrates for liquid crystal displays (LCDs). PBOs were prepared by the one-pot polycondensation in polyphosphoric acid (PPA) from 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane (BAHP6F) with 1,3- and…
Abstract The use of surface energy (wettability) contrast to direct liquid into designated areas, so that flexible substrates can be coated with a discrete pattern in a continuous, roll‐to‐roll manner is described. The method makes use of a substrate prepatterned with lyophilic and lyophobic regions. When this substra…
Several zirconium alloys with differing weight percentages of Cr, Fe, Cu, and Mo were exposed to flowing, pure supercritical water at 500°C for up to 150 days in an effort to determine their corrosion behavior for consideration in the supercritical water reactor. The weight gains of the alloys were measured, and oxide…
Transformer no-load loss and noise have been reduced considerably because of improved core material and improved core design. The variation of normal or interlaminar flux distribution (z direction) in a three-phase transformer core has been measured under pulse width modulation (PWM) excitation (no-load) with switchin…
A new phase-transition mastering (PTM) process was developed for Blu-ray Disc read-only memory (BD-ROM) mastering. Results obtained with both a 266 and 405 nm laser beam recorder (LBR) are discussed in this paper. The feasibility of BD-ROM mastering was successfully demonstrated on both LBRs. With the insight that 25…
Phosphonium compounds are known to act as corrosion inhibitors of mild steel in acidic solutions. They may be added to hydraulic oils or drilling fluids to provide scale and corrosion inhibition. They can be applied on the substrate by immersion or be incorporated in a polymeric coating. In the present work, allyl tri…
Co 3 O 4 nanowire arrays are fabricated by electrodeposition with following heat-treatment in atmosphere ambient. Photoluminescence is investigated at 295 K. In the experiment, when increasing the excitation light wavelength from 260 nm to 360 nm, two kinds of emissions corresponding to the increasing excitation light…
