Interparticle diffraction: a new concept for interstratification of clay minerals

Paul Nadeau、M. J. Wilson、W. J. McHardy 等 4 位作者1984-12-01Clay Minerals

Abstract A new conceptual model for interstratified clays is proposed, based on complementary use of the transmission electron microscope (TEM) and X-ray diffraction (XRD). Clays yielding interstratified XRD patterns are shown to be composed of aggregates of fundamental particles (here defined as an individual or free…

Landau theory of cholesteric blue phases: The role of higher harmonics

H. Grebel、R. M. Hornreich、S. Shtrikman1984-12-01Physical Review A

The Landau theory of blue phases (BP) in cholesteric liquid systems is further developed by systematically including the effect of higher harmonics in the structure factor on the free energy. The inclusion of a third harmonic results in two new body-centered-cubic (bcc) structures, ${O}_{b}^{8}$ and ${O}_{c}^{8}$, in…

Point defects in bcc crystals: Structures, transition kinetics, and melting implications

Frank H. Stillinger、Thomas A. Weber1984-12-01The Journal of Chemical Physics

Structures corresponding to various potential energy minima have been examined for a classical model whose pair interactions produce a body-centered-cubic crystalline ground state. The method used is molecular dynamics computer simulation for 128 particles with frequent steepest-descent mapping onto nearby minima. The…

Glucose metabolism in the extreme thermoacidophilic archaebacterium Sulfolobus solfataricus

Mario De Rosa、A. Gambacorta、Barbara Nicolaus 等 6 位作者1984-12-01Biochemical Journal

Sulfolobus solfataricus is a thermophilic archaebacterium able to grow at 87 degrees C and pH 3.5 on glucose as sole carbon source. The organism metabolizes glucose by two main routes. The first route involves an ATP-dependent phosphorylation to give glucose 6-phosphate, which readily isomerizes to fructose 6-phosphat…

Development of phase morphology in incompatible polymer blends during mixing and its variation in extrusion

Kyonsuku Min、James L. White、John F. Fellers1984-12-01Polymer Engineering and Science

Abstract An experimental study of the development of phase morphology in incompatible polymer melt blends of polyethylene/polystyrene (PE/PS), polyethylene/polycarbonate (PE/PC), and polyethylene/nylon‐6 (PE/N6) is presented. Different temperatures (180°C, 240°C) of mixing and polyethylene molecular‐ weight levels wer…

Abstract A new molecular mechanism for the healing phenomenon in semicrystalline linear polycondensates (healing resulting from chemical reactions between macromolecules located in the interfacial surface) is demonstrated. Strips of commercial poly(ethylene terephthalate) are annealed at 258°C in order to avoid melt s…

Magnesia from seawater: a review

Asif S. Bhatti、D. Dollimore、A. Dyer1984-12-01Clay Minerals

Abstract The process developed in the UK to produce magnesium hydroxide from seawater is described, together with the heat treatment that the hydroxide receives to produce the active oxide. Some of the characteristics required of the dolomite used in the process are also discussed. Impurities introduced by the seawate…

The driving-force dependence of electrochemical rate parameters: origins of anodic-cathodic asymmetries for metal-aquo redox couples

Joseph T. Hupp、Michael J. Weaver1984-12-01The Journal of Physical Chemistry

The consequences of differences in the intramolecular force constants and the ionic entropies between the oxidized and reduced states of aquo redox couples upon their electrochemical kinetics are examined as a function of the driving force. A generalized harmonic oscillator model is utilized that involves estimating t…

Kinetics of the Early Hydration of Tricalcium Aluminate in Solutions Containing Calcium Sulfate

Paul W. Brown、LAWRENCE O. LIBERMAN、Geoffrey Frohnsdorff1984-12-01Journal of the American Ceramic Society

The rates of reaction of 3CaO. Al 2 O 3 , in sulfate‐containing solutions of three compositions were investigated. It was observed that the rates of calcium and sulfate uptake decreased with increasing calcium hydroxide concentration. In a further experiment using a calcium sulfate solution, which also contained NaOH,…
