In this study, the effect of single and double-layer thin film coatings on the reflectance spectrum of silicon surfaces has been investigated. Thin film coatings have been prepared by vacuum evaporation of the materials with suitable refractive index. Reflectance measurements in the visible and near infrared have show…
In this study, thirty-six cultivars of U.S. upland cotton are selected and their wax content determined by the Conrad method. Both ring spun and open-end yarns are then made from these cottons. Various fiber and yarn properties are measured before and after wax removal using AFIS, HVI, the West Point cohesion tester,…
In this study, we investigated the relative contributions of atomic number (Z) and density (rho) to the degradation of the electron backscatter diffraction (EBSD) pattern quality for nanoparticles < 500 nm in diameter. This was accomplished by minimizing the diffuse scattering from the conventional thick mounting subs…
Abstract The crystalline texture and mechanical (tensile and flexural) properties of injection molded nylon 6 were evaluated to understand the influence of the melt temperature ( T mlt ), one of the key‐processing variables. The mechanical properties are found to be sensitive to T mlt only below ∼ 250°C. Rapid quenchi…
Surfacings on steel orthotropic decks act compositely with the steel deck plate and must be regarded as an integral part of the structural deck system. Surfacing materials are generally visco-elastic to plastic and behave elastically only at low temperatures. Elastic moduli of most surfacings strongly depend on temper…
Anodic polarization behaviors of Alloy 600 (UNS N06600) and Alloy 690 (UNS N06690) have been studied as a function of lead content in a solution of pH 4 and pH 10 at 90°C. As the amount of lead in the solution increased, and critical current densities and passive current densities of Alloy 600 and Alloy 690 increased,…

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…
