    摘要: A process for preparing superparamagnetic transition metal nanoparticles by introducing into a gas stream a hydrocarbon and a transition metal carboxyl wherein the transition metal carbonyl is introduced downstream from the hydrocarbon; wherein at the point of introduction of the hydrocarbon the gas stream is in the form of a plasma, and wherein at the point of introduction of the transition metal carbonyl the gas stream is at a temperature of at least 1000° C.; followed by quenching to form carbon-coated transition metal nanoparticles; and wherein the gas stream consists essentially of at least one inert gas and hydrogen.

    摘要: Method and apparatus for isotope separation using the combination of selective pre-excitation by light radiation with further collisional processing in a DC, rf or microwave gas discharge field to recover ionized atoms or dissociated molecules of the selected isotope. Thus, uranium atoms or molecules in gas phase are irradiated in an interaction volume with light radiation of selected wavelength to raise energy states to a relatively stable second or mid-level. At the same time a gas discharge within said interaction volume subjects raised energy atoms or molecules to a collisional process tending to raise a significant number through the energy ladder to the respective ionization continuum or dissociation light whereupon the charged atoms or molecules may be collected as an enriched bulk of selected isotopic species.

    摘要: Glass microspheres were subjected to a multistep spheroidization process resulting in optimized resonant light scattering properties, characterized by a reduction in the particle to particle variation in the intensity contrast of the resonant light scattering spectra. The microspheres have utility in bioanalytical systems which rely on detection of changes in resonant light scattering for detection of analytes.

    摘要: Glass microspheres were subjected to a multistep spheroidization process resulting in enhanced resonant light scattering properties, characterized by having at least three sharp, well-defined resonance peaks in their resonant light scattering spectra. The microspheres have utility in bioanalytical systems which rely on detection of changes in resonant light scattering for detection of analytes.
