The Stable Isotopes of Oxygen in Research and Technical Applications

Abstract

The stable isotopes of oxygen have proved to be efficient research tools; however, only a sinall fraction of the possible applications of these isotopes have been examined so far. The present progress report deals with five basic types of isotopic effects whose investigation and evaluation offer information of a new kind about physical, chemical, and biological systems and processes.

Stable Isotope Geochemistry

“…Friedman et al (1962) conducted laboratory experiments to determine the length of time necessary for single water drops to reach isotopic equilibrium with water vapor. The formation and growth of hailstones has been investigated by Majoube and Roth (cited by Staschewski 1974) by analyzing the radial distribution of the respective isotopes. The formation and growth of hailstones has been investigated by Majoube and Roth (cited by Staschewski 1974) by analyzing the radial distribution of the respective isotopes.…”

Geração química de oxigênio-18 molecular no estado singlete, ¹⁸O₂ (¹Δg), e estudos de lesões em DNA

“…Independentemente da verdadeira cronologia da descoberta desse elemento, somente a partir de 1787 ele foi denominado oxigênio, que significa gerador de ácido, por Lavoisier, que acreditava que todos os ácidos continham oxigênio (Ho et aI., 1995 (Staschewski, 1974 (Khan, 1976 de 2 e 6 ns dentro de miceias de dodecil sulfato de sódio (SDS) e brometo de cetiltrimetilamônio (CTAB), respectivamente (Lissi et ai., 1993). Isso significa que o processo ocorre em toda colisão (controlada por difusão).…”
