ISSN: 1550-7408Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: SYNOPSIS. With the aid of electron microprobe analysis on ciliate spreads, we detected zinc in ciliates and its accumulation in the endoplasm. A correlation was found between the amount of zinc accumulation and its concentration in the medium. By the same microprobe analysis of ultrathin sections, we determined semiquantitatively the zinc accumulation in the intracytoplasmic granules and its presence in macronuclei and in intra- and extracellular bacteria.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8927Keywords: Electrolyte conductance ; single-ion conductance ; ion-pair formation ; ethanol-water ; acetonitrile-water ; isodielectric mixturesSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Precise conductance measurements of solutions of lithium, sodium and potassium nitrates were made at 25°C in acetonitrile-water and ethanol-water isodielectric mixtures, containing up to 15 mole percent organic-solvent, and the data analyzed by the 1978–80 Fuoss conductance equations. Single ion conductances were determined with the help of transference numbers in the case of ethanol-water mixtures. Ion-pair association constants are discussed in terms of contact and solvent-separated ion-pairs and were found to be almost equal to those for the halides. The anion appears more sensitive than the cations to the solvent structure in mixtures rich in water.Type of Medium: Electronic ResourceURL: -

Lanthanum-modified lead titanate thin films have been prepared by a diol-based sol-gel method from precursor solutions with a growing excess of PbO. The films were crystallized with thermal treatments at 650 °C and heating rates of 10 °C min-1 and higher than 500 °C min-1 by direct insertion in a pre-heated furnace. The structure, microstructure, and composition of the films were studied by grazing-incidence X-ray diffraction, electron microscopies, and energy-dispersive X-ray spectroscopy. A 20 mole % excess of PbO must be included in the precursor solution in order to compensate PbO volatilization occurring during the thermal treatment and, thus, obtain single-phase perovskite-type structure films. Non-textured porous films were obtained when a 10 °C min-1 rate is used, whereas [001]/[100] oriented films without porosity were obtained when rapid heating was used. Dielectric permittivity, ac current density, hysteresis loops, and switching curves were measured in the films. Values of remanent polarization and coercive field are comparable to those reported for similar films. The effects on the ferroelectric properties of an electrical and a post-crystallization thermal treatments were characterised.Type of Medium: Electronic ResourceURL: -

ISSN: 0360-6376Keywords: Physics ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: In the presence of oxygen, polymeric materials may undergo diffusion-limited heterogeneous degradation with significant oxidation occurring only near the surfaces. It is important in studying polymer degradation (and in designing accelerated aging experiments) to be able to determine under what conditions heterogeneous degradation occurs, and to estimate the extent of significant oxidative penetration under those conditions. We describe here the use of several techniques for identification of oxidative degradation gradients. A rapid determination of oxidation depth is accomplished by optical examination of metallographically polished cross-sectioned samples; oxidized and nonoxidized regions are distinguished by differences in surface reflectivity. A more detailed determination of the shapes of degradation gradients is accomplished by performing a series of sensitive determinations of relative hardness changes across the surface of cross-sectioned, polished samples. Typical oxidation depths for the commercial polymers examined are on the order of fractions of millimeters over a dose-rate range of 104-106 rad/h. Significant variations among different materials are found, as would be expected given differences in oxygen consumption and permeation rates. A detailed example is given of the tensile property behavior of a Viton material over a range of dose rates where the degradation is seen to change from strongly heterogeneous at high dose rates to homogeneous as the dose rate is lowered. Degradation differences in this material are very pronounced: at high dose rates the polymer undergoes primarily crosslinking to give a hard brittle material, whereas under lower dose rates, where oxygen permeation is complete, the polymer undergoes predominantly scission to yield a soft, easily stretchable material.Additional Material: 6 Ill.Type of Medium: Electronic ResourceURL:
