Drafting force is the direct and intuitive factor resulting in fiber motion in a drafting zone. Utilizing data collected from an ITT Draftometer, this paper discusses the effect of draft ratio and ratch in both the break and the main draft zones on drafting force and the coefficient of variation (CV) of drafting force…
Abstract Terbium alkoxides in homometallic ― [Tb 3 (μ 3 ‐O t Bu) 2 (μ 2 ‐O t Bu) 3 (O t Bu) 4 (HO t Bu) 2 ] ( 1 ), [Tb{OC( t Bu) 3 } 3 (THF)] ( 2 ) ― and heterometallic configurations ― [TbAl(μ 2 ‐O i Pr) 3 (O i Pr) 3 ( i PrOH)] 2 ( 3 ), [TbAl 3 (μ 2 ‐O i Pr) 6 (O i Pr) 6 ] ( 4 ) ― were synthesized and characterized b…
We report a theoretical study of the impact of finite size on the magnetocaloric effect (MCE) of thin Ho films. For strong external field strengths, the adiabatic temperature change ΔTad is comparable to the value found in bulk Ho, reaching about 12 K for an external field strength change ΔH = 50 kOe. For thicknesses…
To minimize radial compliance mismatch between native arteries and vascular prostheses over the entire blood pressure range, a biomimetic woven prosthesis sample with a bilayer wall has been developed. Poly(trimethylene terephthalate) (PTT) filaments were used as the circumferential yarns in the inner layer to increas…
In this research a novel method of coarse wool slandering with minimum tensile strength reduction was explored. To obtain the optimum condition, the response surface methodology through the central composite design in Design of Experiments (DOE) was applied and the optimum values for application conditions were obtain…
The aim of this study was to determine the metastable zone width of aqueous solutions of glycine for non-seeded batch crystallizations. The saturation curve was determined by studying the heating rate influence on the apparent saturation temperatures of several solutions. A linear regression was then applied to obtain…
The multistrata nanoparticle is the culmination of tunable, dual-peak, UV–vis–NIR spectrum extinction characteristics, trimodal imaging contrast, simple synthesis, and facile surface modification capabilities into a single <60 nm diameter, novel, multifunctional, multilayered nanosphere that seeks to relieve current m…
We have investigated the influence of the electric bias field on the magnetic and transport properties of (011)-oriented La0.9Ba0.1MnO3 (LBMO) thin film epitaxially grown on (011)-0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN–PT) single crystal substrate. It was found that strain and polarization effects induced by electric bias…
Abstract The second osmotic virial coefficient, B 22 , of protein solutions is a function of the protein interaction potentials and, thus, summarizes many solution parameters leading to crystallization or precipitation of proteins. B 22 of hen egg‐white lysozyme and bovine serum albumin was measured by static light sc…
Magnetic moment, exchange interaction and Curie temperature (TC) have been calculated for Co2TiGa and Co2FeGa by a first-principles density functional calculation combined with a linear response method. The exchange interaction is dominated by Co-Co pairs in Co2TiGa while that of Co2FeGa is mainly contributed by Fe-Co…
Several electromechanical devices, each consisting of a small bundle of single-walled carbon nanotubes suspended over an actuation electrode, have been fabricated and operated electrically. The nanotubes are assembled on the electrodes using dielectrophoresis, a potential high-rate nanomanufacturing process. A large d…
BACKGROUND: Several human studies have demonstrated the feasibility of intra-arterial delivery of mitoxantrone in systemic malignancies. Computational models predict that an intra-arterial bolus injection of mitoxantrone during transient cerebral hypoperfusion will enhance brain tissue drug deposition in comparison wi…
Based on first principles calculations, we propose a solubility control method of magnetic impurities in dilute magnetic semiconductors (DMSs). The low solubility of Mn in (Ga,Mn)As is experimentally and theoretically known. We show that donor atoms, such as Li, introduced at the interstitial sites in GaAs enhance the…
Abstract A series of poly(butyl methacrylate)s (PBMAs) with various molar masses (33 000–270 000 g mol −1 ), which were densely grafted on fumed silica nanoparticles (PBMA–SiO 2 ), were synthesized by surface‐initiated atom transfer radical polymerization. The dynamic viscoelastic behavior of PBMA–SiO 2 was systematic…
The μ-(oxo)bis[phthalocyaninato] aluminum(III) (AlPc)(2)O films, with the crystallites oriented preferably in one direction, were obtained via chemical transformation of chloroaluminum(III) phthalocyanine AlClPc film upon its annealing in magnetic field. A comparative analysis of the influence of postdeposition anneal…
Abstract Interference of alternative current (AC) on corrosion of X65 steel was investigated in soil. It was observed that the unfavorable effect of interfering AC was able to be effectively inhibited by increasing the direct current density of the cathodic protection (CP) system. A clear correlation was established b…
Abstract The effect of initial supersaturation and temperature on crystal morphology below and above the threshold for the onset of spherulitic growth has been compared for calcium carbonate, L ‐glutamic acid, and an aromatic amine derivative in aqueous systems. For the vaterite polymorph of calcium carbonate is has a…
Abstract The creep behavior of new polymers prepared by free radical polymerization of styrene‐crosslinked resins obtained from linseed oil and derived wood flour (WF) composites have been analyzed. Results of short‐time flexural creep tests at different temperatures are reported. The effects of the wood flour content…
Abstract Ternary solid‐liquid equilibrium diagrams of the system methanol/carbamazepine (CBZ)/nicotinamide (NCT) were generated and are discussed in the range between 5 and 50 °C. A study of the phase diagrams reveals that co‐crystals could successfully be prepared. An evaporative crystallization method was used to pr…
Abstract Stability of the passive state was assessed for pure Zr and four Zr–Nb alloys (2.5, 5.0, 10.0, 25.0 at.% Nb) after 24 h exposure to naturally aerated 3.5% NaCl solution (pH = 6). Open circuit potential values indicated that all the Zr–Nb alloys studied and the pure Zr undergo spontaneous passivation due to sp…
