Mesoporous tin oxide nanoparticles were synthesized by a solid-state mechanochemical route for use as a sorbent in a 68Ge/68Ga generator.
Using a novel, cost-effective and environmentally friendly biosynthesis method, Ni-doped SnO2 nanoparticles have been synthesized. Gas sensing results suggest that the Ni-dopant is a promising additive to fabricate low cost SnO2 based sensors.
