Author … In addition to being a fission product of uranium, as described above, another way to produce ruthenium is to start with molybdenum, which has a price averaging between $10 and $20/kg, in contrast with ruthenium's $1860/kg. The isotope Mo, which has an abundance of 9.6% in natural molybdenum, can be transmuted to Mo by slow neutron irradiation. Mo and its daughter product, Tc, both have beta-decay half-lives of roughly 14 minutes. The end product is stable Ru. Alterna…

WebMay 2, 2014 · Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable). Or even better, we can remove one proton from … WebNMR is a powerful characterization tool and we propose to study the surface of silica or bismuth nanoparticles dedicated to medical applications in order to evidence the covalent grafting of organic molecules on their surface. For that aim, DOSY experiments are particularly useful and allow for the discrimination of molecules interacting strongly with …
