It has been amply demonstrated that thin films of organofunctional silanes deposited by dipping or spraying on metals, such as aluminum, can provide protection against various forms of corrosion. In this paper we show that denser films with higher pore resistance and better corrosion protection performance can be obta…
A new methodology for the computation of the low-temperature part of phase diagrams without recourse to any experimental information is presented. A central element is a procedure for deciding whether formation of crystalline solid solution phases can take place in the chemical system. Via global exploration of the en…
The interaction between a chromia-forming alloy interconnect and ( La , Sr ) MnO 3 ∕ Y 2 O 3 – ZrO 2 (LSM/YSZ) and Gd-doped CeO 2 (GDC)-impregnated LSM electrodes is investigated under solid oxide fuel cell operating conditions. LSM/YSZ and GDC-impregnated LSM composite electrodes show much higher electrochemical acti…
Dispersion of copper oxide via a solvent-free method enables mesoporous silica SBA-15 to become a versatile trap of nitrosamines, exhibiting a high capability to capture volatile nitrosamines and tobacco special nitrosamines (TSNA). 3%CuO/SBA-15 can remove 85% of N-nitrosopyrrolidine (NPYR) in gaseous flow, one fifth…
The reaction of copper(II) hydroxide with 2,2'-bipyridine (bipy) (1 : 1) in alkaline aqueous solution (pH 14) at room temperature affords the alternating carbonate/hydroxo-bridged copper(II) polymeric chain compound {[Cu3(bipy)3(mu-OH)2(mu-CO3)2].11H2O}n, 1, as determined by single-crystal X-ray diffraction. The struc…
Understanding phosphorus-soil interactions is necessary for environmentally sound management of P. The focus of this study was to characterize the P forms and sorption properties of Louisiana calcareous soils and to investigate relationships between these variables and soil matrix properties. Five mildly calcareous so…
Hydrogen-bonded films of poly(vinylpyrrolidone) (PVPON) and poly(acrylic acid) (PAA) were built on a silicon and quartz surface using the layer-by-layer (LBL) assembly technique. Upon incubation, PVPON and PAA chains in the film can attain high-level miscibility and the film becomes homogeneous and transparent. TGA an…
A range of nanocomposites containing polyethylene and montmorillonite (MMT) clay was prepared using different procedures, such that the extent of MMT dispersion varied. The interactions that occur were then studied, together with the effect of MMT dispersion on structure and short-term dielectric breakdown. When the M…
Complexes of lanthanum(III) with bis-coumarins: 3,3'-benzylidene-bis(4-hydroxy-2H-1-benzopyran-2-one) (H(2)L1) and bis(4-hydroxy-2-oxo-2H-chromen-3-yl)-(1H-pyrazol-3-yl)-methane (H(2)L2) were synthesized by reaction of lanthanum(III) salt and the ligands, in amounts equal to metal : ligand molar ratio of 1 : 2. The co…
In the present study, we examined tissue distribution and the antitumor effect of doxorubicin (DOX) after intravenous injection of the pegylated liposomes entrapping the DOX complex with gamma-cyclodextrin (gamma-CyD) (complex-in-liposome) in BALB/c mice bearing colon-26 tumor cells, compared with those of DOX solutio…
This is a review of one manufacturer's efforts toward testing National Electrical Manufacturers Association (NEMA) low-voltage motor insulation for compatibility with adjustable-speed drives (ASDs). Partial-discharge-inception-voltage (PDIV) measurements were selected as a tool to evaluate the future performance of th…
Single-walled carbon nanotube bundles have the potential to provide an attractive solution for the resistivity and electromigration problems faced by traditional copper interconnect. In this paper, we discuss the modeling of nanotube bundle resistance for on-chip interconnect applications. Based on recent experimental…
Hexagonal boron nitride was grown on nickel (110) by chemical vapor deposition of borazine. The h-BN layers on Ni(110) were investigated by low energy electron diffraction (LEED) and angular resolved photoemission (ARUPS). LEED shows a (1 × 6) and a (7 × 5) super structure. ARUPS from the σ bands of h-BN indicates sin…
Luminescence properties of ZnO films, which have been epitaxially grown on c-sapphire (0001) substrates by plasma-assisted molecular beam epitaxy, are investigated by means of different excitation sources and their measurement conditions. With the increase of measurement temperature, photoluminescence spectra clearly…
Gold nanoparticles stabilize chymotrypsin (ChT) against denaturation at the air-water interface through catenation and preferential localization of the nanoparticles at the air-water interface with concomitant decrease in interfacial energy.
A Metal-Insulator-Metal (MIM) device based on a Cu2O insulator has electrical characteristics significantly dependent on the oxide to top electrode (TE) interface. Cu/Cu2O/TE devices with various top electrodes have different thermal release characteristics, related to trap depth. The behavior of the device during era…
BSCF hollow fiber membranes possessing an asymmetric layered structure were prepared using a modified phase inversion process followed by subsequent sintering at temperatures from 1100 to 1175 ˚C. The fibers were characterized by SEM, and tested for air separation at ambient pressure and temperatures between 650 and 9…
Several difluoroisothiocyanato‐based biphenyl tolanes exhibiting high optical birefringence are presented and their representative molecular structure is shown below. The optical birefringence of these liquid crystals lies between 0.44 to 0.48. Several eutectic mixtures of the biphenyltolanes with other compounds have…
