We have investigated the structural and electrical properties of the metal/ferroelectric/insulator/semiconductor (MFIS) structure that incorporates a MgO/SiO2 insulating buffer between a ferroelectric layer and Si substrate. Highly oriented lead–zirconate–titanate [Pb(Zr,Ti)O3, or PZT] films were grown on the MgO-buff…
In this study, the kinetic behaviors of four lanthanide ions, Sm(3+), Dy(3+), Yb(3+) and Lu(3+), when mixed with a polyazamacrocyclic chelating agent 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (DOTA), were investigated by capillary electrophoresis (CE) in the pH range of 2.0-6.0. At pH 2.0, the format…
The bacteria causing foaming in activated sludge plants are considered to be hydrophobic, and their hydrophobicity is assumed to be a crucial factor in their foam-forming ability. This study showed no consistent relationship between cell surface hydrophobicity (CSH), as determined by microbial adherence to hydrocarbon…
Article Controlling the absorption dynamic of water-based ink into porous pigmented coating structures to enhance print performance was published on May 1, 2002 in the journal Nordic Pulp & Paper Research Journal (volume 17, issue 2).
Cationic bis(phosphino)palladium complexes were generated in situ from the reaction of (dppf)PdCl(CH 3 ), (dippf)PdCl(CH 3 ), (dppe)PdCl(CH 3 ), (dppf)PdCl 2, (dippf)PdCl 2, and (dppe)PdCl 2 (dppf = bis(diphenylphosphino)ferrocene, dippf = bis(diisopropylphosphino)ferrocene, and dppe = bis(diphenylphosphino)ethane) wi…
Iodine species released into a reactor containment building following a loss-of-coolant accident is determined by the relative timing and quantity of iodine and other fission products released from the fuel, chemical thermodynamics in the fuel channel, and reaction kinetics in cooler regions of the heat transport syst…
We report the formation of a primitive icosahedral quasicrystal with increased stability in Al-Mn-Be alloys close to the compound Al15Mn3Be2 by melt spinning and injection casting. The crystal structure of this compound was unknown. We show that in as-cast as well as heat treated condition the intermetallic phase HI h…
PURPOSE: Nitinol, a nickel-titanium alloy, is a valuable material in the construction of interventional endoluminal devices because of its biocompatibility, super elasticity, high resiliency and shape memory. The possibility of nickel toxicity has been raised with devices constructed of Nitinol. Our investigation exam…
The objective of this study was to demonstrate that simple fractionation and selective dissolution techniques can be used to provide detailed chemical and mineralogical analyses of flue gas desulfurization by-products. The material studied was a mine grout prepared as a 1:1 mixture (wt./wt.) of fly ash (FA) and filter…
The thermal degradation in air of hemp fabric treated with various compounds containing nitrogen, phosphorus, halogens, and boron, in combinations of two compounds, has been studied by differential thermal analysis and thermogravimetry from ambient temperature to 600 C. The kinetic parameters were obtained using the e…
We have discovered massive icosahedral multiply twinned particles of boron carbide among soot produced during the arc evaporation of carbon and boron in the presence of magnesium. The observation is striking because 5-fold symmetry in large micron size crystals is extremely rare. It is suggested that the icosahedral s…
Abstract High‐luminance triode‐structure field‐emission‐display (FED) panel using carbon nanotubes (CNTs) as emitters was first presented in 1999.[1,2] The demonstrated panel showed a good legibility and excellent luminance. After that, the emission stability in ambient gas was evaluated, and reported in 2000.[3] The…
The severity of four different soil environments toward the development of near-neutral pH stress corrosion cracking (SCC) of pipeline steel was evaluated using slow strain-rate testing (SSRT). These soils were collected from pipeline sites where near-neutral pH SCC has been observed. It was demonstrated in this inves…
Abstract Particulate process modeling is critical for system design and control used widely in the chemical industly. Previous methods have focused on the assumption of appropriate models that can capture system behavior. A new technique presented is based on viewing the population balance from an inverse problem pers…
SSV1 is a virus infecting the extremely thermophilic archaeon Sulfolobus shibatae. The viral-encoded integrase is responsible for site-specific integration of SSV1 into its host genome. The recombinant enzyme was expressed in Escherichia coli, purified to homogeneity, and its biochemical properties investigated in vit…
Films of pure high-quality multiwall carbon nanotubes are grown by laser-assisted thermal chemical vapor deposition in a cold wall reactor. A CO2 laser is used to locally heat a substrate on which nanotubes are grown, employing the catalytic activity of iron nanoparticles. Two kinds of experiments are reported: In a t…
Selective growth of singly oriented (110)-, (100)-, and (111)-MgO films on Si(100) substrates were obtained by pulsed laser deposition. The effects of deposition temperature, ambient oxygen pressure, and etching of the substrate on the structural properties of the films were studied. It is found that the crystalline o…
We correlate fine structure with the adsorption behavior of new (lyocell) and conventional (viscose, modal) regenerated cellulose fibers. We have studied the molecular structure, the fine structure and, most important of all, the amorphous regions and voids in the system. Differences in adsorption properties of all th…
Nanosized powders of single‐phase zinc gallate (ZnGa 2 O 4 ) spinel were hydrothermally synthesized from solutions in the presence of NaOH over the pH range of 1.9 to 7.0 and from solutions above pH 7.0, i.e., the very basic medium (pH of 13.85), by removing the residual ZnO phase by washing with aqueous H 2 SO 4 from…
