    Notes: [Auszug] The net reaction, shown in Fig. 1, involves the irreversible oxidation6 of EDTA; the reaction is endoergic by approximately 20 kilocalories per mol EDTA consumed. This reaction is sensitised in aqueous solutions by the photoexcited triplet state of frw-(2,2-bipyridine)ruthenium2+ (ref. 7). ...

    Notes: [Auszug] Fig. 1 General scheme for water photodecomposition using two half cells of water-in-toluene microemulsions. The model system involves the generation of an oxidised donor (D) and a reduced acceptor (AJ) in the water droplets of two separate half cells using the two sensitisers Si and S2 ...

    Notes: Summary Euphorbia lathyris, a plant which has been proposed as an ‘energy farm’ candidate yields a total of 35% of its dry weight as simple organic extractables. Chemical analyses of the extracts show that 5% of the dry weight is a mixture of reduced terpenoids, in the form of triterpenoids, and 20% of the dry weight is simple sugars in the form of hexoses. The terpenoids can be converted to a gasoline-like substance and the sugars can be fermented to alcohol. Based on a biomass yield of about 25 dry tons ha−1 year−1, the total energy that can be obtained from this plant in the form of liquid fuels is 48 MJ ha−1 year−1, 26 MJ in the form of hydrocarbons and 22 MJ in the form of ethanol. A conceptual process study for the large scale recovery ofEuphorbia lathyris products indicates that this crop is a net energy producer. Several lines of investigation have been started to increase the hydrocarbon yield of this plant. Tissue cultures ofE. lathyris have been established and will be used for selection, with the aim of regenerating a superior plant. Biochemical studies have been initiated to elucidate regulation of terpenoid metabolism. Future plans include eventual genetic engineering to select the most desirable plant for hydrocarbon production.
