Effects of differential sintering kinetics due to differential green density were studied by fabricating agglomerate‐powder matrix specimens from two Al 2 O 3 /ZrO 2 (30 vol%) powders and subjecting them to a cyclic sintering schedule to allow intermittent observations. Low‐green‐density compacts sintered faster than…

PK 11195 [1-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinolinecarboxamide] is a new ligand for the "peripheral-type" benzodiazepine binding sites, chemically unrelated to benzodiazepines. It displaces with a very high potency (IC50 congruent to 10(-9) M) [3H]-RO5-4864 (a benzodiazepine which specifically labe…
It is shown that the current status of the least-squares profile-refinement method, for the determination of crystal structures from X-ray and neutron powder diagrams, allows the simultaneous determination of crystallite-size and lattice-strain parameters. As profile-shape functions the Voigt, pseudo-Voigt and Pearson…

Doping effect of various transition metal halides on polyacetylene were studied in the solution doping as a function of doping time and solvent.
The Weibull distribution for the strength of a long fiber is reviewed, with emphasis on its derivation via extreme-value theory. It is shown that a corresponding Weibull distribution, but with different scale and shape parameters, is appropriate for the lower tail distribution of a bundle of parallel fibers under gene…

Smaller, more charge-intensive electrodes are needed for "safe" stimulation of the nervous system. In this paper we review critical concepts and the state of the art in electrodes. Control of charge density and charge balance are essential to avoid tissue electrolysis. Chemical criteria for "safe" stimulation are revi…
The antiferromagnetic phases of MnO, NiO, and the solid solutions ${\mathrm{Mn}}_{x}{\mathrm{Ni}}_{1\ensuremath{-}x}\mathrm{O}$ ($x=0.24, 0.48, 0.77$) have been examined by high-resolution powder neutron diffraction. The solid solutions have random cation distributions, and N\'eel temperature and mean cation-moment me…
The paper focuses on the derivation of the constitutive law for a material containing flat, planar microcracks. The damage law is derived from the dissipation potential in conjunction with the orthogonality principle. The dissipation potential is shown to exist in the space of conjugate thermodynamic forces related to…
Large single crystals of black phosphorus have been grown under high pressure, and by using the crystals, the Hall measurements have been done in a range from 4.2 K to 550 K. All the undoped samples have exhibited p -type conduction, while we have succeeded in obtaining n -type crystals by doping Te impurity. The effe…
Polyacetylene/polysiloxane interface states have been investigated using metal-insulator-semiconductor (MIS) diodes. The 1-mm2 MIS diodes (Al/polysiloxane/polyacetylene) have been fabricated by use of a conventional photolithographic technique. The I-V and C-V measurements were used to explore the polyacetylene/polysi…

Indium tin oxide (ITO) films have been prepared by the magnetron sputtering technique from a target of a mixture of In2O3 and SnO2 in the proportion 9:1 by weight. By optimizing the deposition conditions it has been possible to produce highly transparent (transmission ∼90%) and conducting (resistivity ∼10−5 Ω cm) ITO…
A detailed study of the polarization and depolarization behavior of 7:65:35 and 8:65:35 lead lathanum zirconate titanate transparent ceramics under dc bias and constant heating rates has been carried out. The dielectric permittivity exhibits a new anomaly near 0 °C in freshly thermally depoled samples which is associa…
Abstract A preparative method has been established for obtaining chitosan products which have a desired degree of deacetylation of up to virtually 100%. Effective deacetylation was attained by intermitently washing the intermediate product in water two or more times during the alkali treatment. The weight average mole…
Optical-absorption, -emission, and -excitation spectra are presented for ${\mathrm{Er}}^{3+}$ ions in fluorozirconate glass. Measured oscillator strengths of the transitions between $J$ manifolds at 300 and 15 K are compared with calculated electric and magnetic dipole oscillator strengths. Radiative rates for five lu…
