Proton-induced reactions on molybdenum
WebbThe most suitable reactions for the production of 99Mo is 100Mo(p,pn)99Mo and 100Mo(p,2p) Nb(15 s) → 10099Mo. For production of 99mTc the Mo(p,2n)99mTc reaction is preferable. Several authors have reported a variety of data of proton induced reactions on the molybdenum but most of these studies are limited to a maximum proton energy … WebbFör 1 dag sedan · Among those, homogenous catalysis and Li-mediated systems are most often pursued, owing to the shortcomings of the N 2 electroreduction in NH 3 in aqueous environment. Indeed, (i) theoretical calculations evidenced that, in the presence of an aqueous proton source, most electrocatalyst surfaces favour the hydrogen evolution …
