  • AbstractIntroductionExperimentalResults and DiscussionGeneral DiscussionConclusionsAcknowledgmentsA fast and efficient automated method using a sequential injection analysis (SIA) system, based on the Griess, reaction was developed for the determination of nitrate and nitrite in infant formulas and milk powder. The system enables to mix a measured amount of sample (previously constituted in the liquid form and deproteinized) with the chromogenic reagent to produce a colored substance whose absorbance was recorded.

Synthesis and Reactions of Cubane-Type IronSulfur A family of soluble, reduced ironsulfur clusters with nuclearities 4, 8, and 16 having tertiary phosphine ligation and based on the Fe4S4 cubane-type structural motif has been synthesized. The results of this investigation substantially extend and improve the results of our original work on ironsulfurphosphine clusters (Goh, C.; Segal, B. M.; Huang, J.; Long, J. R.; Holm, R. H.
