Stable and metastable pitting corrosion of Ti was investigated in neutral and acidic halide solutions. In agreement with earlier findings by others, Br− were found to be significantly more aggressive in triggering pitting corrosion of Ti than Cl−. In Br−-containing solutions, the major factors influencing the occurren…
Plasma protein adsorption patterns on surfaces may give vital information to evaluate biocompatibility of biomaterials designed for direct blood-contacting applications or tissue integration. Adsorption of human serum proteins on four different types of biomaterials (glass, aminosilanized glass, hyaluronan and sulfate…
The crotonase homolog, 6-oxo camphor hydrolase (OCH), catalyzes the desymmetrization of bicyclic beta-diketones to optically active keto acids via an enzymatic retro-Claisen reaction, resulting in the cleavage of a carbon-carbon bond. We have previously reported the structure of OCH (Whittingham, J. L., Turkenburg, J.…
Quantitative analysis method for the calculation of three-dimensional (3D) orientation of poly(trimethylene terephthalate) (PTT) with polarized FTIR-ATR spectroscopy has been discussed. To experimentally obtain a set of four ATR infrared spectra required for 3D orientation analysis, it is necessary to rotate a sample…
A method for thin-film deposition has been studied. The method is based on metal sputtering in a hollow cathode configuration with supply of a reactive gas in the vicinity of the substrate. The working gas and entrained sputtered atoms exit the cathode through an elongated slot. The reactive gas is thereby largely pre…
We propose an input-dependent shape function for the stop model to remove its property of equal vertical chords regardless of dc bias. We compare several identification methods for the stop model and show that the input-dependent shape function improves the ability to represent the stop model effectively. A least-squa…
Thermal elasticity and electrical resistivity with the magnetic phase transition were studied in FeRh alloy films prepared by ion-beam sputtering and subjected to post-annealing. Fe/sub 49.7/Rh/sub 50.3/ and Fe/sub 48.9/Rh/sub 51.1/ films deposited on conventional glass substrate and subjected to post-annealing at 600…
Techniques to fabricate thorium-uranium dioxide fuel [(Th,U)O2] have been developed, and the thermal conductivity of (Th,U)O2 pellets has been measured. Mixtures of thorium dioxide (ThO2) and uranium dioxide (UO2) powders were successfully wet-milled, compacted, and sintered at 1700°C to fabricate (Th,U)O2 pellets. Th…
Helium release measurements and diffusion coefficient calculations of helium in a neutron-irradiated α-SiC have been carried out in the temperature range of 750 1,260°C. The powder was obtained from SiC ceramics containing B4C, of which 10B concentration was 4.2×1016atom/mg. Neutron irradiation was conducted up to a f…
Abstract The dinucleating macrocyclic ligand (L2;2)2−, prepared by the [1:1] cyclic condensation of N,N′-dimethyl-N,N′-ethylenedi(5-bromo-3-formyl-2-hydroxybenzylamine) and ethylenediamine, has dissimilar N(amine)2O2 and N(imine)2O2 metal-binding sites sharing two phenolic oxygen atoms. It has afforded μ-acetato-di-μ-…
Investigations on electrical and electrochemical properties of a new silver tungstate glass system: x[0.75AgI: 0.25AgCl]: (1−x)[Ag2O: WO3], where 0.1≤x≤1 in molar weight fraction, are reported. A “quenched [0.75AgI: 0.25AgCl] mixed system/solid solution” was used as a host salt in place of the traditional host AgI for…
There have been many studies to recycle abandoned Nd-Fe-B magnets. Of these, some studied the conversion of sintered Nd-Fe-B magnet scrap to bonded magnet powder. This conversion, however, has never been used in production yet. The present study aims to develop a highly coercive magnet powder for bonded magnets from N…
The self-assembled two-dimensional random networks composed of isolated SWNTs are obtained by a simple floating catalyst CVD method. A remarkable advantage of this technique is that the random networks can be formed at relatively low temperature with a wide density range, which is distinct from the previous reports. W…
Abstract Size sorted magnetic nanoparticles based on copper ferrite have been chemically synthesized. Their magnetic properties have been investigated at low temperature using Mossbauer spectroscopy and magnetisation measurements. The thermal variation of the magnetization is strongly affected by finite size and surfa…
Abstract This paper reviews the utilization of waste rubber and waste plastics for the preparation of thermoplastic elastomers (TPEs). TPEs based on ground rubber tire (GRT), waste EPDM rubber, waste nitrile rubber, recycled rubber, latex waste, and waste plastics are described with respect to composition and physical…
Hot deformed magnets can be commercially produced from hyper-stoichiometric nanocrystalline Nd-Fe-B compositions. This paper summarizes the influence of the rare-earth component (Nd, Pr, Dy) and gallium to magnetic properties and hot workability of die-upset magnets based upon hyper-stoichiometric compositions. Increa…
Thin cadmium sulfide (CdS) films (100–130 nm) are deposited on glass from an alkaline solution. The films are annealed in air, in the vicinity of a CdCl 2 source, at different temperatures (280–400°C) and for different time periods (below 75 min). The change in some of the optoelectronic parameters (resistivity, direc…
The ferritic-austenitic duplex-steels have a very complex precipitation and transformation behaviour, which requires professional treatment. Especially the precipitation of the {sigma}-phase causes considerable changes with regard to the mechanical as well as the corrosive properties, which are to be considered during…
Thermal stability and the effectiveness of coatings for high-temperature magnets are assessed. Based on several years of experiments and observations, these high-temperature magnets are determined to be metallurgically stable at temperatures up to 550/spl deg/C. These uncoated high-temperature magnets, held at 300/spl…
Investigations of the oxidation behavior of Sm(Co, Fe, Cu, Zr)/sub z/-type high temperature permanent magnets are of particular importance for the assessment of their stability under application conditions in the temperature range up to 500/spl deg/C. Sintered magnets of the Sm/sub 2/Co/sub 17/-type were studied regar…
