This paper develops an objective method of drafting pressure garments to provide predetermined skin-and-garment interfacial pressures on patients. To predict interfacial pressure induced by different sizes of pressure garments on a particular curved surface of the human body, the relationship between the tensile prope…
An oxygen-doped GeSbTe interface layer improves the overwriting characteristics of the phase-change optical disk in the blue wavelength. The thermal and optical properties of oxygen-doped GeSbTe film and its crystal structure were investigated. Crystallization temperature and activation energy of the amorphous Ge–Sb–T…
The identification and discrimination of cubic ( c ) and metastable t ′‐zirconia phases by conventional X‐ray diffraction has proved to be a difficult problem because of the crystallographic similarities of the two phases. In this study, the c ‐phase and t ′‐phase in biphasic metastable zirconia samples have been succ…
Abstract For a better understanding of the physical and electronic properties of emissive carbon films, one of the best ways is to compare the results obtained with several surface and structural analysis techniques. In this article, different types of carbon film depositions for developing large flat panel displays b…
The tensile behaviour of solution annealed type 304L, solution annealed type 304, and solution annealed and sensitised type 304 stainless steels was investigated in hydrogen and helium under a pressure of 1·1 MPa over the temperature range 300–80 K at strain rates ranging from 4·2×10-5 to 4·2×10-2 s-1. For 304L steel,…
The stability of the intermetallics Gd(Fe, T) 12 and the site preferences of the ternary 3d or 4d transition element T are investigated by using a series of interatomic pair potentials, Φ Fe-Fe ( r ), Φ Fe-Gd ( r ), Φ Fe-T ( r ), Φ T-T ( r ), Φ T-Gd ( r ), and Φ Gd-Gd ( r ), for the first time. The calculated results…
ABSTRACT: Pepsin‐solubilized collagen (PSC) prepared from the skin of 3 fish species—common horse mackerel, yellow sea bream, and tiger puffer—were separated into 2 fractions, major and minor, by ammonium sulfate precipitation. These collagen fractions were further purified by phosphocellulose column chromatography. F…
Different mechanisms of spin pairing in doubly reduced polyoxometalates are studied on the basis of quantum-chemical DFT calculations. Using the nitrosyl derivative of decamolybdate [Mo(10)O(25)(OMe)(6)(NO)](-) (I) as an example, we elucidate an important role of the delocalization of "blue electrons". The charge dist…
The formation of silicon powder by pyrolysis of silane diluted in argon at different concentrations has been studied. A hot wall gasphase reactor was used for the thermal decomposition of SiH4 at 1000 °C and atmospheric pressure. The composition, morphology, size, and shape of the particles produced has been studied u…
Porous poly(ε-caprolactone) (PCL) films were prepared by the removal of poly(L-lactide) (PLLA) from phase-separated PLLA/PCL blend films using the selective Proteinase K™-catalyzed hydrolysis of PLLA and subsequent elution of its water-soluble oligomers and monomer into the surrounding hydrolysis media. Polarimetry, g…
Abstract A theoritical model of the production of open‐cell microcellular foam is presented. This model allows the prediction of the conditions necessary to produce these materials. Experiments verify the model quite well. The results of the batch processing experiments indicate the processing parameters that promote…
Abstract The application of carbon-silica dual phase fillers (CSDPF) to natural rubber compound was investigated. It was found that these new fillers give significantly better overall performances in comparison with the conventional fillers—carbon black and silica. In a typical truck-tread compound, due to its high po…
Optical properties of Yb3+–Tb3+ codoped silica sol-gel samples have been studied after the gel to glass transition. Different upconversion emissions have been observed under near infrared excitation at about 1 μm. The Tb3+ ions are excited by means of energy transfer processes from Yb3+ ions. The temporal evolution of…
The luminescence lifetimes of An(III) and Ln(III) ions [An=Am and Cm; Ln=Nd, Sm, Eu, Tb and Dy] were measured in dimethyl sulfoxide(DMSO), N,N-dimethylformamide(DMF), methanol(MeOH), water and their perdeuterated solvents. Nonradiative decay rates of the ions were in the order of H 2 O > MeOH > DMF > DMSO, in…
The structural and electrical characteristics of a thermally grown gallium oxide on GaN films were investigated. A furnace oxidation at 850 °C for 12 h resulted in the formation of monoclinic β-Ga2O3, 88 nm in thickness. From the I–V measurements of the metal–oxide–semiconductor (MOS) structure, the breakdown field st…
We report the first experimental results on the temperature dependent in-plane and cross-plane thermal conductivities of a symmetrically strained Si/Ge superlattice and a Ge quantum-dot superlattice measured by the two-wire 3 omega method. The measured thermal conductivity values are highly anisotropic and are signifi…
A simple one-dimensional continuum model for electromigration transport has been fairly successful as a tool for understanding many empirical observations of electromigration phenomena in encapsulated interconnect lines on integrated circuits. In this paper, the development of the one-dimensional continuum electromigr…
To resolve relationships between members of the family Thermomonosporaceae, phylogenetic analyses using three sets of nucleotide sequences from 16S rDNA, 23S rDNA and the 16S-23S internal transcribed spacer (ITS) were carried out. Nearly all species of the family were included in this study. On the basis of congruous…
Photoinduced effects on the charge- and orbital-ordered (CO/OO) states in a layered perovskite manganite ${\mathrm{La}}_{0.5}{\mathrm{Sr}}_{1.5}{\mathrm{MnO}}_{4}$ have been investigated with femtosecond polarization-sensitive pump-probe spectroscopy. Disappearance of the optical birefringence as well as conspicuous c…
Polarized photoluminescence in orientated thin films of π-conjugated oligomers is demonstrated here. Vapor-deposited thiophene/p-phenylene co-oligomers are described and it is shown that these molecules form epitaxial needle-like crystals (see Figure). Molecular modification of the co-oligomers enables the emission co…
