The toughening of wood-plastic composites (WPC) based on silane/ peroxide macro crosslink poly(propylene) (PP) systems was studied. A 23 experimental design was adopted to initially optimize three parameters: silane, wood flour, and talc contents of the WPC formulation. The WPCs were manufactured on a co-rotation twin…
This text arose from a study originally undertaken for the Department of Energy to characterize the principal safety features of light water reactors of western design. This text should be of use to professional engineers interested in safety assessment of operating light water reactors, students interested in the pri…
Abstract Mineral deposition is observed in both bacterial and eukaryotic organisms through a broad range of mechanisms. Both organic and inorganic components play crucial roles in the formation of mineralized tissues, and acidic proteins are particularly important in this context owing to their ability to stimulate nu…
Entrapment of cytotoxic drugs inside endocytizable carriers such as liposomes improves the specificity of the drug and reduces its toxicity towards non diseased cells. Work in this field has resulted in the development of polyacrylamide nanocapsules. The major advantage of alkylcyanoacrylates over other acrylic deriva…
Our objective in this book and in subsequent volumes of the Uniscience Series on Water Pollution Control Technology, is to provide a reference manual for design engineers, planners, and managers in industry and government. This is particularly important in the present critical period for implementation of water pollut…
The object of this book is to review and to discuss some important applications of polymers in electronics. The first three chapters discuss the current primary applications of polymers in semiconductor device manufacturing: polymers as resist materials for integrated circuit fabrication, polyimides as electronics pac…
This chapter reviews the areas of collagen structure which have been analyzed by X-ray diffraction and to examine questions at various levels of connective tissue organization that may be resolved by X-ray studies. X-ray diffraction is a tool capable of determining structure from the molecular level to the tissue leve…
This paper studies the magnetization process in electrical steel sheets for rotational magnetizations as they occur in the magnetic circuit of electrical machines. A four-pole rotational single sheet tester is used to generate the rotating magnetic flux inside the sample. A field-oriented control scheme is implemented…
BACKGROUND AND PURPOSE: Previous studies have evaluated various gadolinium based contrast agents and their association with gadolinium retention, however, there is a discrepancy in the literature concerning the linear agent gadobenate dimeglumine. Our aim was to determine whether an association exists between the admi…
The relationship between Mn concentration and Curie temperature (TC) is studied for Mn-doped ZnSnAs2 ferromagnetic semiconductors, epitaxially grown on InP substrates by molecular beam epitaxy. In the ferromagnetic phase, Mn distributions in a (Zn,Mn,Sn)As2 thin film with 7.2 cation percent (cat. %) Mn are investigate…
The novel hollow spindle with spiral guide grooves is introduced into the manufacture of Murata vortex spun yarn for the sake of enhancing the vortex yarn’s strength. By means of numerical simulation, the airflow characteristics in the conventional twisting chamber and novel twisting chamber of Murata vortex spinning…
Abstract This work represents the first complete experimental and theoretical study of the infrared (IR) spectra of pharmacolite, Ca(AsO3OH)·2H2O; vladimirite, Ca4(AsO3OH)(AsO4)2·4H2O; and picropharmacolite, Ca4Mg(AsO3OH)2(AsO4)2·11H2O. IR spectra, collected at both room and liquid nitrogen temperature, have shown sim…
In this study, azomethine polyphosphonates were synthesized by solution polycondensation of phenylphosphonic dichloride with various azomethine diols such as [4-(4-hydroxy phenyl) iminomethyl] phenol, [(4-(4-hydroxy-3-methoxy phenyl) iminomethyl)] phenol and [4-(4-hydroxy-3-ethoxy phenyl) iminomethyl] phenol using tri…
The physical-mechanical properties of bamboo-polyethylene composites (BPCs) change depending on the environmental temperature and exposure to moisture during outdoor use. In this study, the water absorption, density, mechanical properties, and wear rate of the composites were tested after immersion in water, and four…
The syntheses, structural characterization, and magnetic properties of three lanthanide complexes with formulas [Ln(L1)3] (Ln = Dy (1Dy); Er (1Er)); and [Dy(L2)2] (2Dy) were reported. Complexes 1Dy and 1Er are isostructural with the metal ion in distorted trigonal-prismatic coordination geometry, but exhibit distinct…
We consider primitive aperiodic substitutions of constant length $q$ and prove that, in order to have a Lebesgue component in the spectrum of the associated dynamical system, it is necessary that one of the eigenvalues of the substitution matrix equals $\sqrt{q}$ in absolute value. The proof is based on results of Que…
Abstract Recently, ZnO nanowire field effect transistors (FETs) have received renewed interest due to their extraordinary low dimensionality and high sensitivity to external chemical environments and illumination conditions. These prominent properties have promising potential in nanoscale chemical and photo-sensors. I…
As the threat of global climate change due to combustion emissions becomes increasingly alarming, the search for clean and sustainable alternative energy is of paramount importance. With this objective in mind, harnessing solar energy is particularly attractive due to ongoing improvements in silicon‐, perovskite‐, and…
A novel scheme is designed to prepare superior catalysts with good activity, high selectivity, outstanding stability, excellent resistance to sintering and carbon deposition. In the scheme, the ions of lanthanum, strontium, cobalt, and gallium were confined into La 1– x Sr x Co 0.65 Ga 0.35 O 3 with perovskite structu…
Perpendicular magnetic tunnel junctions (MTJs) have attracted increasing attention owing to the low energy consumption and wide application prospects. Herewith, against Julliere's formula, an inverse tunnel magnetoresistance (TMR) appears in tetragonal Fe4N/BiFeO3/Fe4N perpendicular MTJs, which is attributed to the bi…
