Intermediate and high-mass ion beams from a 10-cm Duopigatron
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-06)
Experimental studies of a 10-cm Duopigatron as a source of argon, krypton, and xenon ion beams are reported. Source plasma instabilities are examined, and the mass dependence of oscillation frequencies and instability onset ...
Concentration dependence of the first cumulant for partially labeled chains in dilute solutions
(John Wiley & Sons, Inc., 1984-05)
We use Zimm's single-contact approximation to investigate the concentration dependence of the first cumulant for partially labeled chains in dilute solutions. This approximation allows us to express interchain properties ...
The reaction of pyrite with diphenyl ether
(Elsevier, 1984)
Diphenyl ether is converted into diphenyl sulfide (largely), dibenzofuran, phenoxybiphenyls, diphenoxybiphenyls, and several other sulfur- containing compounds by reaction with pyrite at 350-360[deg].
Gold-titania interactions: Temperature dependence of surface area and crystallinity of TiO2 and gold dispersion
(Elsevier, 1984-05)
The influence of temperature on the BET surface area, crystallinity, and anatase/rutile phase transformation of blank TiO2 and Au/TiO2 catalysts is studied. Presence of gold delays the recrystallization of anatase and the ...
Ultrastructural and microanalytical results from echinoderm calcite: Implications for biomineralization and diagenesis of skeletal material
(Elsevier, 1984)
Magnesian calcite skeletal elements of the modern crinoid echinoderm Neocrinus blakei were studied using high resolution TEM, high voltage TEM and STEM microanalysis. Unlike inorganic magnesian calcites which are compositionally ...
Electrolyte-moderated interactions in water/oil microemulsions
(Elsevier, 1984-11)
Interactions between the disperse phase droplets of water-in-oil (W/O) microemulsions of Aerosol-OT are profoundly affected by the addition of small amounts of electrolyte. We find that the effect of added electrolyte in ...
Formation And Growth of Amorphous Phases By Solid-State Reaction In Elemental Composites Prepared By Cold-Working
(American Institute of Physics, 1984)
Effects of anharmonicity of molecular vibrations on the diffraction of electrons : Part V. Tetrahedral molecules
(Elsevier, 1984-05)
Unless the skewing of radial distribution peaks is properly taken into account, diffraction analyses of gas molecules may lead to geometrically inconsistent arrays of internuclear distances. It is shown how to derive the ...
Coagulation processes with a phase transition
(Elsevier, 1984-01)
Smoluchowski's coagulation equation with a collection kernel K(x, y) ~ (xy)[omega] with describes a gelation transition (formation of an infinite cluster after a finite time tc (gel point)). For general [omega] and t > ...
Calculations on the helium isoelectronic sequence using Coulomb Green's function variables
(Elsevier, 1984-02-24)
Calculations on the ground states of the helium isoelectronic series are carried out using variational wavefunctions of the form [psi] (x,y), in which x and y are the combinations r1 + r2 +/- r12 occurring in the Coulomb ...
