Aqueous Homogeneous Reactors (AHRs) or simply solution reactors present nowadays a promising alternative to produce medical isotopes, especially 99Mo. The AHR medical production concept has been proposed to produce medical isotopes directly in the fu

One of the many applications of stable isotope analyses is in hydrological studies. As the isotope concentration of elements in water vary as a result of fractionation due to physico-chemical processes, each water has its own “fingerprints”, so t
