Abstract The three-dimensional crystal structure of rotationally disordered illite/smectite (I/S) in K-bentonite samples from the Appalachian basin and neighboring areas is described using the parameters of 1) P 0 , the proportion of zero-degree layer stacking rotations, such as in the polytype series 1Md-1M ; 2) P cv…

Abstract In order to realize a higher valency ion conduction in solids, the Sc2(WO4)3 material which possesses a larger tunnel size for ion migration was selected to reduce the electrostatic interaction and the single crystals of Sc2(WO4)3 were grown to eliminate grain boundary effects found in polycrystalline state.…
Measurements of the enthalpy relaxations in liquid orthoterphenyl in the supercooled state have been carried out using specific-heat spectroscopy over the frequency range from 2 Hz to 6.3 kHz, as a function of temperature and as a function of pressure. The observed \ensuremath{\alpha}-relaxation peaks in the phase of…
A comparative study of cyclic fatigue damage from Hertzian contacts in silicon carbide ceramics with homogeneous microstructure (fine, equiaxed grains, strong grain boundaries) and heterogeneous microstructure (coarse, contiguous elongate grains, weak interphase boundaries) is presented. Observations of the surface an…
The solution structure of the isolated fragments 1-20 (beta-hairpin), 21-40 (alpha-helix) and 41-56 (beta-hairpin), corresponding to all the secondary structure elements of the protein G B1 domain, have been studied by circular dichroism and nuclear magnetic resonance techniques. In the protein G B1-(1-20) fragment tu…
Two complexes of gallium with 3-hydroxy-4-pyrones were synthesized as potential pharmaceutical compounds for oral administration. These compounds were analyzed by powder X-ray diffraction followed by computer indexing of the data. The first compound, tris(3-hydroxy-2-methyl-4-pyronato)gallium [Ga(C 6 H 5 O 3 ) 3 ], wa…
Organic materials are particularly well suited for the fabrication of pyroelectric devices due to their processability and ease of formulation as thin films with low thermal capacity and low thermal conductance. Attempts to produce organic structures which can be used as active elements in such devices are described.
For many years now, two‐component epoxy coatings have been used in a wide range of industrial applications, including traditional market areas such as floor paints and concrete sealers. Originally, the majority of such products were thinned with petroleum‐based solvents, but in the 1970s, Thomas Swan introduced Casami…

SUMMARY A general formulation for the secondary fluorescence correction is presented. It is intended to give an intuitive appreciation for the various factors that influence the magnitude of the secondary fluorescence correction, the specimen geometry in particular, and to serve as a starting point for the derivation…

Abstract The effect of blend ratio on the crosslinking characteristics and dynamic elastic properties of HDPE/EPDM blends was studied by a torque rheometer. The crosslink density (a measure of tensile strength) first increases and then decrease with increase in EPDM content. The dynamic elastic property (a measure of…
Abstract The rheology of aqueous suspensions of Na halloysites with different particle shape has been investigated using a Haake rotary viscometer. Three halloysites from New Zealand were used: Matauri Bay (MB), Te Akatea (TA) and Opotiki (Op) which are mainly composed of thick long tubules, short thin laths, and sphe…

A binary Lennard-Jones fluid was cooled in an NPT ensemble by molecular-dynamics simulations. Depending on the cooling rate, we find a sharp transition from the melt either into a disordered structure or into a phase of icosahedral long-range order. We also observed a decagonal phase.
Statistically designed experiments have been made using partial carboxymethylated cotton fabric. The effects of three reaction parameters (concentrations of sodium hy droxide and monochloroacetic acid and time period) on wet pickup and carboxyl content are presented using polynomial models. Monochloroacetic acid conce…
