The lighter isotope generally forms weaker bonds than the heavier one and tends to react faster. The change in isotopic abundance is called fractionation (Karasov & Martínez del Rio 2007).

As a result, the heavier isotopes react more slowly than the lighter isotopes leading to isotopic separation or fractionation between reactant and product in both physical and biological reactions.

were used to predict the potassium isotope fractionation. The interactions of the potassium isotopes are involved in the functioning of the sodium-potassium-adenosine triphosphatase (Na/K ATPase ...

The stable isotope concentrations of a molecular compound or material are presented in ratio form as the molar ratio of the heavy-to-light isotopes. Since this ratio is small, we typically present ...

Hereby, the development of analytical techniques for high-precision isotope and trace element measurements and the development of quantitative tools for the investigation of local and large-scale ...

The Stable Isotope Laboratory in the Department of Geological and Environmental Sciences at Western Michigan University uses known stable isotope techniques for geochemical, hydrological and other ...

A new testing technique developed using synchrotron light could significantly improve how we monitor the effectiveness of ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...
