The surface stability of intertidal cohesive sediments maintained in a laboratory tidal ecosystem was examined in relation to the migratory behavior of epipelic diatoms. Stability was measured by a new portable device—a cohesive strength meter. Diatom#x2010;inhabited sediments increased significantly in surface stabil…
Recent development of shape memory alloys is reviewed, emphasis being placed on theTi–Ni, Cu–based and ferrous alloys which are considered as practical materials for applications among many shape memory alloys. Crystal structures of the parent and martensitic phases are described, and the crystallography of the marten…
The author reviews surface flashover (i.e. voltage breakdown along the surface of insulators), primarily in vacuum. He discusses theories and models relating to surface flashover and pertinent experimental results. Surface flashover of insulators in vacuum generally is initiated by the emission of electrons from the c…
Methodology is described for the culture of avian and mammalian chondrocytes in ionotrophically gelled "semi-solid" and "hollow" alginate beads. Chondrocytes grown in "semi-solid" gels exhibited a spherical shape as opposed to a fibroblastic morphology observed in monolayer culture. In the "semi-solid" beads, the cell…
Solidification behaviour controls the size and shape of grains, the microstructure, the extent of segregation, the distribution of inclusions, the extent of defects such as porosity and hot cracks, and ultimately the properties of weld metal. In the past, theories related to single crystal growth technology and the so…

The adsorption of CO and CO2 on cerium oxide has been studied by Fourier-transform infrared spectroscopy (F.t.i.r.). For CO adsorption at room temperature, in addition to linearly adsorbed CO (2177 and 2156 cm–1), two kinds of carbonate (unidentate: 854, 1062, 1348 and 1454 cm–1 and bidentate: 854, 1028, 1286 and 1562…

Starting from a general quantum-mechanical perturbation theory on the nonlinear optical (NLO) effect in crystals, this review gives a systematic presentation of the basic concepts and calculation methods of the ‘anionic group theory for the NLO effect of crystals’ and a brief discussion of the approximations involved.…

The pharmacokinetics (distribution, metabolism, bioavailability, excretion) and toxicity (acute and subacute toxicity, mutagenicity) of a superparamagnetic iron oxide preparation (AMI-25), currently used in clinical trials, were evaluated by 59Fe radiotracer studies, measurements of relaxation times, the ability to re…
The polyanilines are a class of polymers the base form of which has the general formula [graphic omitted] containing y reduced and (1 –y) oxidized repeat groups. y can in principle be varied continuously from one, the completely reduced material, to zero to give the completely oxidized polymer. The emeraldine oxidatio…
Issues concerning powder consolidation methods compatible with the colloidal approach and issues associated with other powder processing steps, viz., densification and microstructural control, are presented with regard to research directions leading to more reliable ceramics.
Volume 13 of Reviews in Mineralogy presents much of our present-day knowledge of micas. Since 1984 was too much material available to attempt to cover all of the hydrous phyllosilicates in one volume, the micas were treated first because of their abundance in nature and the fact that many detailed studies had been car…
The temperature dependence of Cr 3+ photoluminescence has been measured in the garnets Y 3 Ga 5 O 12 , Gd 3 Sc 2 Al 3 O 12 and Gd 3 Sc 2 Ga 3 O 12 . The observed intensities in the 2 E g to 4 A 2g and 4 T 2g to 4 A 2g emission transitions are interpreted using a model based on the effects of small changes in unit-cell…
Successful growth of (100)ErAs single-crystal films on (100)GaAs has been demonstrated. Reflection high-energy electron diffraction, low-energy electron diffraction (LEED), and Rutherford backscattering with channeling indicate single-crystal growth. LEED from the ErAs shows a (1×1) structure. Overgrowth of GaAs on Er…
Deuterium NMR of nematic droplets in a polymer matrix reveals the effect of confinement on molecular orientational ordering near the nematic-isotropic ($N\ensuremath{-}I$) phase transition. For large droplets of 0.35 \ensuremath{\mu}m in diameter, the $N\ensuremath{-}I$ transition is first order. For droplets of less…
