    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The side-effects of pesticides and metal cations are reviewed with regard to input, distribution, persistence and toxicity. The sensitivity of microbial processes is discussed in relation to adaptability and resistance of microbial populations. Procedures for an ecological assessment of toxic side-effects are discussed.

    Homogeneous Chromium Catalysts for Olefin Polymerization (1998)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 1998 (1998), S. 15-24 
    Details
    ISSN: 1434-1948
    Keywords: Chromium ; Organometallics ; Homogeneous catalysis ; Olefin polymerization ; Polyethylene ; Chemistry ; General Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Chromium-based heterogeneous catalysts are used extensively for the polymerization of olefins. There are few homogeneous model systems that allow investigation of the reaction mechanisms and unique characteristics of chromium catalysts. Coordinatively unsaturated paramagnetic chromium alkyls containing a Cp*CrIIIR fragment (Cp* = η5-C5Me5, pentamethylcyclopentadienyl) catalyze the polymerization of ethylene and α-olefins. Correlations between molecular structure and catalytic activity are reviewed.
