(U,Pu)O2 solid solutions are completely soluble in boiling 5 and 10 M nitric acid up to plutonium concentrations of 55 and 65 wt% of PuO2, respectively. The dissolution of the solid solutions decreases drastically at plutonium concentrations above 35 and 40 wt% of PuO2 in 5 and 10 M nitric acid, respectively, with a t…
Article Single crystal X-ray investigation of norsethite, BaMg(CO3)2: one more mineral with an aplanar carbonate group was published on October 1, 1985 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 171, issue 1-4).
Abstract Molecular weight distributions, long chain branching frequency, and solution viscosities of samples of commercial poly(vinyl alcohol) (PVA) are reported. The PVA was fully reacetylated to poly(vinyl acetate) (PVAc) for characterizations by size exclusion chromatography using a low angle light scattering detec…
The formation of the tetragonal Fe14La2B phase has been examined in both as-cast and melt-spun Fe-La-B alloys using thermal and magnetic techniques together with x-ray diffraction analysis. It is found that this phase exists in both types of alloys and that it is produced by annealing at relatively low temperatures. T…
<p>The well-resolved ESR powder spectra of blue platinum complexes prepared from 1-methylhydantoin and 5-methyl-2-pyrrolidinone offer the possibility of probing various structural models. A good agreement between the experimental and the calculated spectra is obtained by assuming that the hyperfine structure is…
Abstract The topic of electromagnetic interference (EMI) has been reviewed briefly to outline the need for conductive composite materials. The characteristics of a conductive filler which lead to high efficiency at small filler concentrations were examined qualitatively. One of these characteristics, aspect ratio, was…

SUMMARY The methods for vitrifying pure liquid water are reviewed: jet‐freezing of water/oil emulsions, vitrification of thin water layers on an electron‐microscope specimen grid, high‐pressure jet‐freezing and rapid cooling of aerosol droplets on a cryoplate. The first three need a liquid cryomedium for heat transfer…
We describe a new Thiobacillus species which is a gram-negative, motile, rod-shaped organism having polar flagella. The optimum growth temperature is 43 to 45°C, and the optimum pH range is 6.0 to 7.5. This organism is obligately chemolithotrophic and autotrophic and has ribulose bisphosphate carboxylase activity. It…
This paper is concerned with the a priori theory of the photoemission process in solids. Scattering-theoretical and response-theoretical approaches are discussed and a new demonstration of their equivalence is given. The elastic photoemission spectrum is analyzed in detail and an expression exact to all orders in inte…
Electrical conduction in amorphous In x Se 100- x films is actually n -type, although some workers have considered it to be p -type, since p -type conduction is observed in the partially-crystallized films. A fairly large upward-Fermi-level-shift appears, in particular, in films with composition near x =40. Raman meas…
