    Notes: Abstract  Nod factors are lipochitooligosaccharides (LCOs) secreted by rhizobia. Nod factors trigger the nodulation programme in a compatible host. A bioassay was set up to test how crude (NGR234) and purified (NodS) Nod factors influence cell division and somatic embryogenesis in a conifer, Norway spruce (Picea abies). The Nod factors promoted cell division in the absence of auxin and cytokinin. More detailed studies showed that NodS stimulates development of proembryogenic masses from small cell aggregates and further embryo development. However, stimulation was only observed in low-density cell cultures. Our data suggest that rhizobial Nod factors substitute for conditioning factors in embryogenic cultures of Norway spruce.

    Iron antimony oxide selective oxidation catalysts – an inelastic neutron scattering study (2000)
    Springer
    Topics in catalysis 11-12 (2000), S. 223-227 
    Details
    ISSN: 1572-9028
    Keywords: allyl iodide ; 3-iodopropene ; allylpalladium chloride ; selective oxidation catalyst ; inelastic neutron scattering ; vibrational spectra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The inelastic neutron scattering spectra of allyl iodide (3-iodopropene, CH2=CHCH2I) and allylpalladium chloride, and allyl iodide dosed onto activated iron(III) oxide and iron antimonate catalysts at room temperature have been determined to characterise the adsorbed allyl species. The spectra are energy loss vibrational spectra in the range 16–4000 cm−1. Allyl iodide is not decomposed on the surface and interacts through the localised C = C bond, more strongly with iron antimonate than with iron(III) oxide.
