Abstract The crystal structure of malachite is refined ( R = 0.021) with the intensity values of 635 independent neutron reflexions from a single crystal, rather free from absorption and extinction. Concerning the structural geometry, no essential deviations occur from the known results of x-ray diffraction. The therm…

Abstract In spite of the importance of fatigue behavior in engineering plastics, relatively few fundamental studies have been made of the effects of polymer structure, molecular weight, composition, and morphology on fatigue crack propagation (FCP). As, part of a broad program for the study of such effects, the role o…

Samples in the composition range Fe0.95O-Fe0.88O quenched from about 1000°C, have been studied by electron diffraction/microscopy with special emphasis on the dark-field technique. The set of morphologies obtained by quenching and annealing confirms a spinodal-like decomposition in an oxygen-rich and an almost stoichi…

Cell adhesion and spreading were studied on sulphonated polystyrene dishes in serum-free saline (Mn, Na, Cl, buffer) i.e., without an intervening protein layer. Spreading as a function of surface charge density, SCD, peaked around 2-10 negative charges per square nanometer, corresponding to a monomolecular layer of su…

Abstract The early development of ideas on cation exchange from 1850 to 1900 is described. From 1900 to the present, the coverage has been divided as the work has concentrated on soil acidity, alkali soils, and classical cation exchange studies. The discovery of crystallinity in soil clays and the rediscovery of the i…

Both structures have been observed in the same highly annealed fiber, suggesting that the polymer should not be regarded as…

The effects of Dy doping and sintering parameters on the properties of BaTiO 3 ceramics were studied. The average grain size decreases with increasing Dy content and is controlled at ∼1.5 μ m by 0.8 at.% Dy. The Curie temperature change, associated with ≤1.2 at.% Dy, is <3°C. The dielectric constant is ∼2600 for sp…
