Bioorganometallic Technetium and Rhenium Chemistry: Fundamentals for Applications

Technetium and Rhenium - Coordination Chemistry and Nuclear Medical Applications

Compostos de coordenação do elemento radioativo tecnécio são empregados para diagnóstico em medicina nuclear, sendo vários complexos do nuclídeo emissor de radiação γ Tc usados rotineiramente na obtenção de imagens de órgãos. As tendências modernas da química radiofarmacêutica concentram-se na marcação de moléculas biologicamente ativas tais como peptídeos, esteróides ou outras espécies com rec...

Unusual metalloporphyrin complexes of rhenium and technetium.

Long-chain rhenium and technetium glucosamine conjugates.

A series of five glucosamine-conjugated organometallic complexes of the tricarbonyl cores of technetium-99m and rhenium were made. Glucosamine was derivatized at the C-2 nitrogen with long chain alkyl spacers linked to either pyridyl-tert-nitrogen-phenol tridentate chelates or cyclopentadienyl ligating groups. The metal complexes of the tridentate ligands were formed by refluxing with [Re(CO)(3...

Chemical Kinetics – Fundamentals and Applications in Atmospheric and Combustion Chemistry

Shock tubes are quite universal tools to study high-temperature reactions in the gas phase (800 K < T < 3000 K). A gas mixture is rapidly (t < 1 μs) heated by a travelling shock wave, and species formed behind the shock front are time-resolved detected, where we use absorption spectroscopy [1] and mass spectrometry. [2] Kinetic data are inferred from the concentration-time profiles. A recent ex...
