This book presents original research results on the leading edge of chemistry research. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. Topics discussed include lymphoscintigraphy using 99mTc-labeled colloidal particles; structural and stereoisomers in the chemistry of Ge, Sn and Pb complexes; Re/Tc radiopharmaceutical design utilizing orthogonal and metal template based click reactions; modulation of yield and stereoselectivity of glycosylation; advances in asymmetric Diels-Alder reactions; fructose and the Reaven’s syndrome; hydroxyacids and neurodegenerative disorders; the transmutation of technetium; applications of the Von Mises distribution (VMD) of circular statistics to chemical and environmental engineering; and the molecular composition and uses of technetium.
