Ge 140 a. Stable Isotope Geochemistry. 9 units (3-0-6); second term, 2020-21. An introduction to the principles and applications of stable isotope systems to earth science, emphasizing the physical, chemical and biological processes responsible for isotopic fractionation, and their underlying chemical-physics principles.

As aging nuclear reactors require increased maintenance, and even shut down completely, the strain on their production is being felt far beyond the energy industry: inside oncology and cardiac clinics. But help is on the way.

In this respect, −6.57‰ is the most negative Ge isotope composition value reported in any sphalerite or seafloor sulfides to date. Controls on Ge isotope fractionation during extreme weathering of basalts. Both theoretical calculations and adsorption and coprecipitation experiments indicate that light Ge isotopes are preferentially enriched on the surfaces of Fe-oxyhydroxides (Δ 74 Ge Fe-oxide–Solution = − 1.6 to −4.4‰) (Li and Liu, 2010, Pokrovsky et al., 2014).

We present measurements of Ge isotope composition and ancillary data for samples of river water, low- and high-temperature hydrothermal fluids, and seawater. The dissolved δ74Ge composition of analyzed rivers ranges from 2.0 to 5.6 per mil, which is significantly heavier than previously determined values for silicate rocks (δ74Ge=0.4-0.7 per mil, Escoube et al., Geostand.

New ENDF-6 formatted nuclear data libraries are presented for 70,72,73,74,76 Ge, for incident neutrons and protons.
